The cutest, most useful pet in Minecraft.
That's a bold claim, so allow me to demonstrate. Adorable Hamster Pets stuffs Minecraft with pint-sized, jiggly fur-missiles that have a craving for... diamonds.
Perfect for anyone who surveys their diamond-encrusted empire and mutters, “Needs more rodents.”
These hamsters like to bounce, shoulder-surf, hoard snacks, sniff for things, and moonlight as throwable projectiles, all while adding maximum charm and helping with your inventory clutter. Tame, feed, or yeet at will; (ethics optional).
TL;DR Features, for the Impatient
- 3000+ Wild Variants – (discovery! science! questionable taming decisions!)
- Procedural Breeding – discover up to 2.2 million unique variants through breeding
- Acorn Armor – from biodegradable Acorn shells to Netherite plating
- Dynamic Animations – procedural napping, cleaning, and personality-based sit/sleep poses
- Wear Up to Three Hamsters – mount them on your shoulders & head, jiggle physics included
- Shoulder-Surfing Perks – portable creeper radar & diamond divination, powered by cheese
- Hamster Yeet™ (press G) – turns your shoulder buddies into furry, squeaky missiles
- Tamed Wander Mode – link them to Hamster Beds so they stop following you
- Item Stealing – hamsters play high-stakes keep-away with your valuables; highly configurable
- Potent Vegetables – stuff their face with Steamed Green Beans and witness the chaotic zoomies
- Diamond Sniffing – complete with dramatic sulking animations if they accidentally find gold instead
- Cheek Pouches of Holding – six inventory slots inside the hamster (cheeks visibly expand when full)
- Automatic Eating From Cheeks – they can snack on their own if they have Hamster Food Mix
- Wild Cucumber & Green Bean Bushes – use them for rodent bribes... or decor, if you're into that
- Cheese Crafting – surprisingly moist snack for players; hamsters find it intoxicating
- In-Game Guidebook – a wealth of ancient hamster knowledge, plus cozy illustrations
- Custom Advancement Tree – so you can gamify your rodent wrangling
- Global Loot Injection – find hamster gear in ancient loot chests; archaeologists baffled
- Hyper-Configurable – customize everything, from spawning to yeet velocity
- Widely-Compatible – all interactions & mechanics based on configurable c:tags
Bribe them with Sliced Cucumber and they'll follow you like a furry, ankle-biting shadow. They have unique personalities that dictate how they sit and nap. Yes, they even have a dedicated "Path to Slumber" animation sequence.
Lure up to three hamsters onto your person using Cheese. They aren't just static decorations; they are fully animated, physics-enabled passengers that bounce when you jump and hold on for dear life when you sprint. While up there, they act as portable radar systems, squeaking alerts for nearby Creepers and Diamonds.
For when words fail and you need a furry, surprisingly aerodynamic solution— press 'G'. Behold as your shoulder companion becomes a surprisingly effective, albeit concussed, projectile. Includes satisfying particle trail, impact sound effects, and the Doppler Effect! Does enough damage by default to kill a creeper, which is... really convenient.
So, you want a server? I gotchu.
I've researched many different server hosts and also tried a few myself. Until recently, I thought Apex Hosting was the best... until I tried Indifferent Broccoli. They deserve at least 7 out of 5 stars in my book. They are superior in every way:
- Top-Tier Hardware (they live up to their slogan of eating lag for breakfast)
- Full Modded Support (even on their cheapest servers. Apex doesn't offer that)
- Incredible Customer Service (you can literally just ping them on Discord and they fix it)
- Affordable (somehow cheaper than Apex Hosting while also being better :O)
- Approachable (just feels like a group of friends who love gaming)
- Uninterrupted Uptime (my server generated chunks 24/7 for 3 days lol)
And I just recently discovered their Split the Cost feature. Your server comes with a payment link— toss it in the group chat, and your friends can directly contribute to the server's monthly bill in two seconds. Ridiculously easy. I thought it was so cool I give it its own paragraph LOL.
Sign up by clicking the banner above. You'll get yourself a great server AND help fund my hamster shenanigans for future updates!
Throw a hamster at an Oak Tree. It will vanish into the canopy, physically rustling the leaves and raining down Acorns. You can use the acorns to craft Acorn Armor and the stylish Acorn Hat accessory.
Craft a Hamster Bed, link it to your hamster, and place it. They will stop following you and wander freely near their bed. If they get stuck somewhere, just go to sleep— they'll find their way home during the night. Comes with numerous interactive controls specific to each bed.
P.S. - Don't place the bed upside down. Just don't do it.
If they smell diamonds while on your shoulder, put them down. They will lead you to the ore. Note: they sometimes mistake Gold for Diamond, and will exhibit a dramatic sulking animation when they realize their error.
They'll energetically implement hamster kung fu on enemies. They like round-house kicks. Even includes particle effects on their feet.
Craft Acorn Armor (works like Wolf Armor, negates all damage until it breaks). Upgrade it with Smithing Templates found in chests:
- Iron: Aerodynamic. Reduces wind resistance for a faster throw.
- Gold: Lightweight. Grants a permanent movement speed buff.
- Diamond: The "Expensive Therapy" upgrade. Cures kleptomania. A diamond-clad hamster is so satisfied with its own shininess that it will fetch shiny things for you instead of stealing them.
- Netherite: Dense. Grants Knockback Resistance and massive throw impact damage.
Your hamster's love for shiny things may have evolved into full-blown kleptomania. Unless wearing Diamond armor, they will steal valuable items dropped on the floor and run away with them. Catch them to retrieve your loot (just diamonds by default; configurable).
OUTDATED AS OF v3.6.0 - UNDER CONSTRUCTION
73+ variants spawn based on biome (White in snow, Black in caves, Lavender in magical biomes). Compatible with Terralith/Biomes O' Plenty/Oh the Biomes You'll Go out of the box. Configurable enough to work with any other mod that adds custom biomes. When bred, they pass their diverse fur coat palettes on to their offspring, with a polite attempt to not exactly copy their parents' overlay patterns, ensuring maximum genetic variety in your ever-growing population.
A Field Guide to Hamster Habitats
- Orange & Cream: The most common type, often found sunning themselves in Plains, Savannas, Deserts, and non-frigid Beaches. Badlands also seem to attract the Orange ones.
- Chocolate: Prefers the shaded canopy of Forests and non-snowy Taigas (excluding Cherry Groves, those are special).
- Black: Enjoys the damp ambiance of wet biomes like swamps and the mysterious depths of the Deep Dark.
- Light Gray & Dark Gray: These stoic shades are common in non-frozen mountainous regions and also share cave real estate with their Black brethren.
- White: Exclusively found in most snowy biomes (Plains, Taiga, Groves, etc.) and makes up about 30% of the population in the extremely chilly Ice Spikes.
- Blue: A master of glacial camouflage. This rare variant's cool, blue-tinted fur is an uncanny match for the shimmering ice and packed snow of the most frigid landscapes. While vary rare in the default game, (only spawns in Ice Spikes), its love for ice means it might also be spotted in other crystalline wonderlands added by mods.
- Lavender: Less about survival and more about style, this variant's dusty purple coat is a perfect match for the fantastical flora of magical biomes. Look for them amidst the pink petals of Cherry Groves and the strange hues of Mushroom Fields. Their preference for the peculiar means you might also find them in other enchanted forests or mystical groves added by mods.
Feed them Hamster Food Mix to earn their trust and cheek pouch access. Sneak + Right-Click to access 6 inventory slots. They will automatically eat Hamster Food Mix from here if hurt.
For reasons known only to Notch himself, Ravagers and Spiders are utterly terrified of hamsters. The mere sight of a tiny ball of fluff will send these hulking monstrosities fleeing in the opposite direction. Highly effective crowd control, especially if you have arachnophobia.
You get one automatically the first time you join a world (unless you turned that off in the config, you rebel). It contains tips. Read it. Or use it as kindling, but don't come crying into the Discord server unless you've read it first.
Need a new one? Craft it with minecraft:book + adorablehamsterpets:sliced_cucumber, or get a new one for free by vising the config and clicking the "I Lost My Book" button. You can also grab it from the Creative Mode tab if you're lazy.
Cucumber and Green Bean Bushes
- Cucumbers: Found in warm or dry biomes (Plains, Savannas, Jungles). Right-click seeded bushes to harvest. Essential for crafting Sliced Cucumber, the only currency wild hamsters accept for taming.
- Green Beans: Found in wet or temperate areas (Swamps, Lush Caves, Flower Forests). Harvest these to craft Steamed Green Beans, a potent performance-enhancing drug for small rodents.
Slightly Less Useless Sunflowers
Vanilla sunflowers merely exist; mine produce. Right-click the head to harvest Sunflower Seeds (used for food mix). They naturally replace vanilla sunflowers in valid biomes. They can be farmed and will regrow seeds eventually. Be patient.
New Food Stuffs
- Cucumber/Green Beans: Grow 'em, eat 'em raw (if you must), slice 'em, steam 'em. Culinary possibilities are… present. Wild hamsters go nuts for these.
- Steamed Green Beans: A suspiciously potent super-food for your hamster. Grants temporary buffs, followed by a mandatory "please wait" period. Don't get greedy.
- Hamster Food Mix: Allegedly gourmet. Heals well, bypasses their irritating pickiness, and is the key to unlocking their cheek pouches. Craft it. Or don't. Your hamster, your problem.
- Cheese: Not only can it lure hamsters onto your shoulder, it's player-edible. Surprisingly nutritious (think cooked porkchop levels) and you can scarf it down about 30% faster than most foods. The only catch? The... distinctively moist eating sound. Consider it an acquired taste. Its nutritional value is fully configurable, for those of you who felt cheese was somehow "unbalanced." Plebs.
Feed your hamster Steamed Green Beans to trigger a state of pure, unadulterated zoomies. They gain substantial buffs to Speed, Strength, and Regeneration, and will proceed to run energetic circles around you (complete with particle trails) until the sugar crash hits.
This humble pile of leaves and twigs, officially known as Hamster Bedding, is the cornerstone of hamster interior design. You'll need it to craft the aforementioned Hamster Beds.
But its true calling? Unnecessary ambiance. Right-click the item in the air (or put it in a Dispenser) to unleash a glorious poof of decorative leaf particles.
These aren't just any particles. Oh no. I've blessed them with a ridiculously over-engineered client-side physics simulation. They float with a gentle pendulum sway, react to a universal wind drift that slowly changes direction over a three-minute cycle, (or stays static if you toggle it) and are subject to "spatially-coherent wind gusts"—a fancy way of saying they all realistically blow in the same direction at the same time.
I even created an "indoors/outdoors" detection algorithm so the system is even smart enough to know when it's indoors, regardless of how you built your house or what materials you used. This system disables the wind effects indoors so you don't get a sudden gust of wind in your hobbit hole. You already have enough going on in there.
It's deeply unnecessary, and I'm incredibly satisfied with it.
P.S. - Remember, don't place your hamster bed upside down. Don't even think about it.
Hamsters have a dedicated Bling inventory slot. Right-click them (or use their inventory) to equip accessories. Use Pink Petals for pure style points, or the Acorn Hat to boost yields during Tree Heists. Many more fashion items are planned for future updates!
Future Accessory Plans
The current accessory collection is... sparse, but the hamster haberdashery is just getting started. The Discord community suggestion box is overflowing with ideas that range from "brilliant" to "medically concerning," so future updates might just include some of the following hamster adornments:
- Adventuring Gear: For the hamster with heroic delusions. Think tiny swords, shields, armadillo armor, and even a dried kelp eye-patch.
- Fruit-Themed Headwear: Because who doesn't want a hamster wearing a tiny banana?
- More Flower Decoration Types: We've already got pink petals, but we need ALL THE COLORS.
- Hats and Crowns: Flower crowns for when your hamster needs to feel like the tiny, unelected monarch of the forest floor, and top hats for absolute sophistication.
- And much, much more...
These are subject to change! Got a genius idea for the next hamster accessory that absolutely needs to exist? Think you've designed the perfect tiny helmet? Bring your brilliant, weird, and wonderful ideas to The Cheek Pouch Discord Server. Make sure you select "Share Your Genius" in the screening questions to get the @Idea Generator role, and then unleash your creativity in the suggestions channel.
A custom advancements tab, "The Hamster Life," guides you through the thrilling world of hamster husbandry, from finding your first seed to... um, yeeting.
The goal was a subtle, spoiler-lite tutorial system designed for people who hate reading manuals (I know you're out there). If you're ever wondering "what am I supposed to do with this rodent?", just press L and check the advancements tree. It follows a logical progression, gently nudging you from basic foraging and taming all the way up to advanced mechanics like cheek-pouch management, bed linking, and the various... jiggly physics experiments.
If you follow the advancements, you'll naturally discover most features in the mod without needing to tab out to your browser every three minutes. Plus, I spent way too much time writing the unique titles and descriptions for each one, so they are worth checking out. You might even experience a small chuckle.
- Go Outside: Wander aimlessly through Plains, Savannas, Forests, Swamps, etc., until you trip over Wild Cucumber Bushes or Wild Green Bean Bushes. Right-click the ones that look like they have seeds. Collect said seeds.
- Pretend to Farm: Plant seeds on farmland. Wait. Harvest. Try not to starve while waiting for virtual vegetables.
- Questionable Crafting: Turn Cucumbers into Sliced Cucumber (the bait). Turn Green Beans into Steamed Green Beans via furnace (for buffs). Cobble together various seeds and carrots into Hamster Food Mix (for healing). Turn Milk into Cheese (the Shoulder Shenanigans starter kit). Refer to your recipe book, I'm not writing recipes here.
- Attempt Taming: Find a wild hamster. Sneak. Hold Sliced Cucumber. Approach like you're diffusing a tiny, furry bomb. Click. Repeat until successful or rage-quit.
- Basic Hamster Operations: Right-click to sit/stand. Sneak + Right-click for cheek inventory access (after feeding Food Mix!). Wave Cheese around to shoulder-mount. By default, you crouch to dismount, or Press 'G' to dismount... rapidly. However, the whole dismounting process is highly configurable. You can choose between a single or double tap, and also set a custom keybind if you like.
Total Control
Uses Fzzy Config for configuration. If you have Mod Menu, click the button. If not, venture into the config/adorablehamsterpets folder and edit main.toml by hand like some kind of digital caveman.
Thanks to the magic of Fzzy Config, all the server-side settings are validated and synced from the server. That means if you have a server, you set the rules. Whatever you decide the taming difficulty, hamster damage, or acceptable cheese nutrition levels are, your players will abide by it. They can't change these core settings locally unless you give them the keys to the kingdom. A few purely cosmetic client-side settings are the exception, but the important stuff? That's all you.
There are no hard-coded hamster interaction items— everything can be modified.
- Redefine their diet. Make your hamsters demand Nether Stars for taming. Make them steal only dirt blocks. Whatever. Live your truth.
- Fine-tune the physics. Adjust the velocity, damage, and cooldown of the Hamster Yeet. Tweak the potency of the Green Bean zoomies.
- Become a cheese tycoon, or nerf it into the ground. The nutritional value of cheese is fully configurable and even syncs with AppleSkin's HUD on Minecraft 1.21.1 (older versions are out of luck due to API shenanigans).
Out-of-the-Box Harmony
From the beginning the goal was to make this play nice with the big names. Hamster spawning is pre-tuned for gorgeous world-gen mods like Terralith, so your lavender hamsters will actually show up in lavender fields, but It also works with massive mods like Oh The Biomes You'll Go and Biomes O' Plenty, though expect to see a lot of the common orange variant until I've had enough coffee to map out their 8,000+ biomes. (As of version 3.4.0, you can now do this yourself! Check Config > Hamster Spawn Settings > Variant Spawning by Biome)
Wild bushes and sunflowers should pop up just fine in any modded landscape, but if you run into issues, you can tweak the settings: Config > Worldgen: Bush & Sunflower Stuff.
Thanks to some glorious assistance from @CasualAnimalEnjoyer, this mod is also compatible with the following mods by default:
Immersion, Because Details 💅🏼
The sound effect and particle systems are smart enough to keep up with customized items. For example, if you mount your hamster with an emerald instead of cheese, it won't make a "squish" sound anymore; it'll make a satisfying "clink" and sparkle with emerald particles. This dynamic system applies to most interactions, ensuring the audio and visual feedback always matches your custom configuration. (Even works with custom modded items!)
Want to make a gameplay video? A review? An addon that gives them tiny hats? A parody song about the cheese economy? Go for it. I love seeing the stuff this community creates, and I want to keep it welcoming.
However, please don't use my branding (the logo, specific asset art, or official-sounding social posts) to advertise your own stuff. Nah fam.

Some cave hamsters have inhaled a little too much redstone dust, so naturally the treatment now includes a flute solo. Redstone Fever introduces rare aggressive cave encounters and a sunlight rescue challenge, while the new Acorn Flute can distract threats, call trained hamsters to your shoulder from a configurable distance, and is also used to obtain a new music disc.

Why? Because I didn't want to overwrite everyone's custom worldgen config settings in case some people have spent a lot of time on it.
### Added
- Redstone Fever**
- You might now come across rare wild aggressive cave hamsters with scars, glowing red eyes, rapid health regen, new animations, redstone particles, 3 new custom sound effect types, and unpredictable circular energy bursts. Thanks to [@The Retro Stitcher](https://theretrostitcher.com/) for the original Redstone Fever concept/idea!
- Currently, Redstone Fever is only applied when a hamster first spawns. Existing hamsters cannot contract it. I might add contagiousness in the future if it's requested.
- Food cannot tame, distract, or pacify an untreated hamster. You'll need to play a riff on the Acorn Flute to briefly interrupt its attacks while it keeps watching you with those red eyes. Lead it above redstone depth and keep it in direct clear sunlight for 3 Minecraft days to cure the condition and restore ordinary wild behavior.
- How do you lead it? You're the bait. Better find some good armor. For your toes.
- Spawning, sunlight treatment, aggression, bursts, and eligible dimensions are configurable. The Jade HUD overlay can optionally show Severe, Recovering, or Nearly Cured status if you enable it.
- Added a set of hidden config settings commissioned by the **After Beyond Networks** team for their upcoming "Ultimate Nightmare" event. These settings allow pre-existing wild hamsters to resolve one hidden surface-surprise roll when first approached by a player. Each result persists, so reloading or changing the chance cannot reroll the same hamster. These settings are purposefully hidden at the bottom of the config under "Commissioned Features." This changelog is the only place they will be mentioned.
- Acorn Flute & Acorn Music Disc**
- Thanks to [@The Retro Stitcher](https://theretrostitcher.com/) for the base Acorn Flute idea, the crafting recipes and the flute textures!
- Craft separate Lush, Ember, and Harmony Acorn Flutes from Acorn Shards, string, and pitcher plants or torchflowers. All three stack to 16 and share the same mechanics; the color is purely cosmetic at this stage, but does affect the color of the musical note particles.
- Play from your main hand to begin one of random riff sounds. You can play again right away to switch sounds. Switching items ends your active performance immediately. You can't play a flute if you aren't holding it. Duh. Different players can perform at the same time, so multiplayer flute incidents remain fully supported. I tried to make sure all the sounds were in E minor, but I'm not a music expert, lol.
- Server owners can turn up an Anti-Spam Cooldown that enforces a minimum wait between flute plays (config, just 0.5 seconds by default— I didn't want to punish your shaky aim if you intended to summon the hamster to your shoulder but missed the target and played a normal riff instead).
- Normal riffs can be heard up to 80 blocks away (very quiet) and distract threats within 16 blocks by default.
- You can distract creepers and fevered hamsters with the flute. Server owners can decide whether you should be able to calm all creepers or charged creepers only in the config.
- Fevered hamsters keep pursuing players while distracted, but won't attack or frantically sprint around in circles.
- Look directly at an owned hamster within 8 blocks while you have an open shoulder or head slot, and your flute will play a shorter chiff sound instead of the normal riff. The hamster will think about what that means, and then jump onto your shoulder. Successfully repeating this will train that exact hamster from a 3-second response toward 1 second after a configurable number of mounts (50 by default). A new optional Jade HUD line shows
Untrained,Learning,Responsive, orAttuned. I left it off by default since the Jade HUD is already getting crowded. - A flute-assisted sunlight cure qualifies that exact hamster for the Acorn Music Disc ritual. Tame it, mount it, then throw it at a charged creeper while any player's normal riff is actively calming the creeper. The qualified rescuer must make the killing throw; but failed attempts do not consume the qualification so if you can find another charged creeper you can try again.
- A successful ritual replaces the ordinary Cheese Music Disc drop with one Acorn Music Disc. It contains a fully licensed zampoña style version of the AHP theme song.
- Acorn Ring**
- Craft an Acorn Ring from an Acorn Hat and four Copper Ingots, or find one independently in uncommon loot chests.
- Wear it in your offhand with no extra mod, or in a ring slot through [**Accessories**](https://modrinth.com/mod/accessories)
[**Curios API**](https://modrinth.com/mod/curios) on Forge/NeoForge.
- When two players both wear a ring, their pets will not target the other player or pets that player owns—even in
- An offhand ring stays out of sight. Removing either ring ends protection without starting a fight.
- By default, the ring also keeps you from accidentally hitting your own pets. A separate setting can extend that
- Hamster Combat Timer**
- Standard-mode hamsters now abandon a fight after 30 seconds without relevant combat from their owner. Menace mode remains professionally unreasonable.
- Per-Hamster Armor Visibility**
- Each hamster inventory now has a compact checkbox for hiding that hamster's armor without removing its protection.
- Hamster Turning Animations**
- Idling hamsters now shuffle their paws and rock their body when rotating in place instead of gliding around like a robotic turntable.
- Hamster Reset Command**
- Added
/ahp reset_hamsterfor server OPs. It returns the nearest hamster to a freshly spawned wild state while
cooldowns, and other history get a clean slate.
- Redstone Fever Admin Commands**
- Added
/ahp redstone_fever applyand/ahp redstone_fever curefor server OPs. With no target, each affects the nearest live hamster within 16 blocks; pass an entity selector when the whole cave needs attention. Doesn't work on tamed hamsters, and admin cures won't grant advancements. - New Hamster Tips Guidebook Entries**
- Redstone Fever**
- Explains how to interrupt attacks with an Acorn Flute riff, and the **Musical Rodentry** entry gained a page hinting at how to get the new Acorn Music Disc.
- Acorn Flute**
- Explains how a riff distracts creepers and interrupts fevered hamsters, how to summon a hamster onto your shoulder, and how successful mounts train that hamster to respond faster.
- Hide & Seek Minigame**
- Explains the start message, hiding-place clues, time limit and reward so people don't keep asking me why their hamster disappeared lol.
- New Advancements**
- Redstone Fever**
- Discover a hamster suffering from Redstone Fever. Apparently prolonged redstone exposure has side effects.
- Flute-Assisted Recovery**
- Cure a fevered hamster with prolonged direct sunlight and good music. Medical licensing remains pending.
- The Final Note**
- Complete the Acorn Music Disc ritual with the same hamster you helped cure. Poetic. Legendary.
- Hide and Squeak**
- Find your hamster during a game of Hide & Seek before time runs out. Apparently this counts as responsible pet ownership.
### Changed
- Limited Sulking & Knocked Out States**
- Hamsters now recover from being knocked out or sulking within 10 seconds at most.
- I did this so you can more easily find your hamsters easier after throwing them. When they were permanently knocked out, they would never teleport to you in that condition.
- Teleport Rescue**
- My custom rescue code that brings following hamsters with you through all kinds of teleports is now silent and does not include particle effects. Its destination and delayed-spawn behavior remain unchanged. I just wanted to make sure it won't conflict with the new [**Void Hamster**](https://docs.google.com/document/d/1xlr4_pgvQ2KUDc4nyUVGhpClXSoFtABiVfZbJshMgps/edit?usp=sharing) coming in the next update.
- Long-distance rescue now cancels active minigames when the owner moves far enough away, while ordinary minigame behavior remains uninterrupted and commanded-sitting or bed-sleeping hamsters stay in place.
- Teleport Rescue now applies to hamsters that are knocked out and sulking. When they spawn next to you at the new location, they will be normal.
- Fast and Slow Hamster Dancing**
- Hamsters now bounce to Fast song matches and loop a new swaying animation to Slow matches. The existing
dancingMusicDiscStringssetting and all saved values remain the Fast list; the new Slow list defaults tolow-fiandzampoñaand wins when both lists match. For example, if a song name contained both “hamster” and “zampoña," a nearby hamster would do the slower dance. - Food Gets a Hamster's Attention**
- Every configured hamster food can now lure eligible hamsters, temporarily interrupting ordinary combat without
- Begging is reserved for taming food and shoulder-mount treats. Other food attracts them without the performance.
- Recipe Output Adjustments**
- Hamster Food Mix crafting now produces 4 Hamster Food Mix instead of 1.
- Acorn Composting**
- Acorns now compost more reliably, and now you can also compost Acorn Shards for a smaller but still useful contribution, and Acorn Hats provide the lowest contribution.
- Cycle Aggression States Without Sneaking**
- Configured Pacifist, Standard, and Menace items now change aggression through ordinary feeding.
- If the hamster is already in Standard aggression mode, configured sunflower seeds remain ordinary food.
- Flowers now equip as accessories with sneak + right-click, keeping normal right-click available for feeding.
- Instantly End Hamster Fights**
- Feeding your hamster a flower during a fight will instantly wipe its memory of the current target without enabling Pacifist mode.
- Trying to enable **Pacifist mode**? Just feed it a second flower while it is calm.
- Less Frequent Hide & Seek Games**
- Doubled the default initiation interval from roughly 3 minutes to roughly 6 minutes. *Existing worlds retain their
default.*
- Shoulder Hamster Throw Selection**
- Throwing now skips hamsters whose cooldown is still active and selects the next ready hamster in the configured
- Snowshoe Hamsters**
- Hamsters now walk on top of powdered snow instead of sinking in, and thrown hamsters land on the drift rather than vanishing into it. Hamsters are lightweights so it feels like it always should have been this way. Now your hamsters can comfortably watch you freeze to death.
### Fixed
- Chiseled Bookshelves**
- The Hamster Tips guidebook can now be stored in chiseled bookshelves.
- Crop Tag Compatibility**
- Cucumber and Green Bean crops now work with vanilla crop and farmland-maintenance checks, improving compatibility with crop-focused mods.

- Missing White & Pearl Rose Hamsters**
- If you've been exploring snowy biomes hoping to find pure white hamsters, you might have wondered why you were getting mostly blue and sky-colored hamsters instead. Snowy biomes were accidentally getting lumped into the "Icy" environment group, but they now correctly spawn with their intended snowy coat colors.
- This happened because the color-sorting system checks for Icy biomes before Snowy ones, and the Icy filter was accidentally set up to catch anything labeled as "snowy." Since snowy biomes got caught in the icy filter first, they were given icy blue palettes instead of white ones.
- If you've been looking for Pearl Rose hamsters in Magical Environments and couldn't find any, it wasn't just bad luck. A typo in the Magical Environment config names kept the settings from loading correctly, so Pearl Rose hamsters couldn't spawn there.
- Also cleaned up a few modded biome defaults and restored compatibility tag support so hamsters spawn properly across modded biomes.

<font color="red">**IMPORTANT:**</font> If you've been looking for **White** or **Pearl Rose** hamsters and couldn't find them, this update fixes that— but **with one important condition:** you must follow the _**Missing White & Pearl Rose Hamsters**_ instructions down below (I colored it red) to manually restore the affected settings to their new defaults. Why? Because I didn't want to overwrite everyone's custom worldgen config settings in case some people have spent a lot of time on it.
### Added
- Redstone Fever**
- You might now come across rare wild aggressive cave hamsters with scars, glowing red eyes, rapid health regen, new animations, redstone particles, 3 new custom sound effect types, and unpredictable circular energy bursts. Thanks to [@The Retro Stitcher](https://theretrostitcher.com/) for the original Redstone Fever concept/idea!
- Currently, Redstone Fever is only applied when a hamster first spawns. Existing hamsters cannot contract it. I might add contagiousness in the future if it's requested.
- Food cannot tame, distract, or pacify an untreated hamster. You'll need to play a riff on the Acorn Flute to briefly interrupt its attacks while it keeps watching you with those red eyes. Lead it above redstone depth and keep it in direct clear sunlight for 3 Minecraft days to cure the condition and restore ordinary wild behavior.
- How do you lead it? You're the bait. Better find some good armor. For your toes.
- Spawning, sunlight treatment, aggression, bursts, and eligible dimensions are configurable. The Jade HUD overlay can optionally show Severe, Recovering, or Nearly Cured status if you enable it.
- Added a set of hidden config settings commissioned by the **After Beyond Networks** team for their upcoming "Ultimate Nightmare" event. These settings allow pre-existing wild hamsters to resolve one hidden surface-surprise roll when first approached by a player. Each result persists, so reloading or changing the chance cannot reroll the same hamster. These settings are purposefully hidden at the bottom of the config under "Commissioned Features." This changelog is the only place they will be mentioned.
- Acorn Flute & Acorn Music Disc**
- Thanks to [@The Retro Stitcher](https://theretrostitcher.com/) for the base Acorn Flute idea, the crafting recipes and the flute textures!
- Craft separate Lush, Ember, and Harmony Acorn Flutes from Acorn Shards, string, and pitcher plants or torchflowers. All three stack to 16 and share the same mechanics; the color is purely cosmetic at this stage, but does affect the color of the musical note particles.
- Play from your main hand to begin one of random riff sounds. You can play again right away to switch sounds. Switching items ends your active performance immediately. You can't play a flute if you aren't holding it. Duh. Different players can perform at the same time, so multiplayer flute incidents remain fully supported. I tried to make sure all the sounds were in E minor, but I'm not a music expert, lol.
- Server owners can turn up an Anti-Spam Cooldown that enforces a minimum wait between flute plays (config, just 0.5 seconds by default— I didn't want to punish your shaky aim if you intended to summon the hamster to your shoulder but missed the target and played a normal riff instead).
- Normal riffs can be heard up to 80 blocks away (very quiet) and distract threats within 16 blocks by default.
- You can distract creepers and fevered hamsters with the flute. Server owners can decide whether you should be able to calm all creepers or charged creepers only in the config.
- Fevered hamsters keep pursuing players while distracted, but won't attack or frantically sprint around in circles.
- Look directly at an owned hamster within 8 blocks while you have an open shoulder or head slot, and your flute will play a shorter chiff sound instead of the normal riff. The hamster will think about what that means, and then jump onto your shoulder. Successfully repeating this will train that exact hamster from a 3-second response toward 1 second after a configurable number of mounts (50 by default). A new optional Jade HUD line shows
Untrained,Learning,Responsive, orAttuned. I left it off by default since the Jade HUD is already getting crowded. - A flute-assisted sunlight cure qualifies that exact hamster for the Acorn Music Disc ritual. Tame it, mount it, then throw it at a charged creeper while any player's normal riff is actively calming the creeper. The qualified rescuer must make the killing throw; but failed attempts do not consume the qualification so if you can find another charged creeper you can try again.
- A successful ritual replaces the ordinary Cheese Music Disc drop with one Acorn Music Disc. It contains a fully licensed zampoña style version of the AHP theme song.
- Acorn Ring**
- Craft an Acorn Ring from an Acorn Hat and four Copper Ingots, or find one independently in uncommon loot chests.
- Wear it in your offhand with no extra mod, or in a ring slot through [**Accessories**](https://modrinth.com/mod/accessories)
[**Curios API**](https://modrinth.com/mod/curios) on Forge/NeoForge.
- When two players both wear a ring, their pets will not target the other player or pets that player owns—even in
- An offhand ring stays out of sight. Removing either ring ends protection without starting a fight.
- By default, the ring also keeps you from accidentally hitting your own pets. A separate setting can extend that
- Hamster Combat Timer**
- Standard-mode hamsters now abandon a fight after 30 seconds without relevant combat from their owner. Menace mode remains professionally unreasonable.
- Per-Hamster Armor Visibility**
- Each hamster inventory now has a compact checkbox for hiding that hamster's armor without removing its protection.
- Hamster Turning Animations**
- Idling hamsters now shuffle their paws and rock their body when rotating in place instead of gliding around like a robotic turntable.
- Hamster Reset Command**
- Added
/ahp reset_hamsterfor server OPs. It returns the nearest hamster to a freshly spawned wild state while
cooldowns, and other history get a clean slate.
- Redstone Fever Admin Commands**
- Added
/ahp redstone_fever applyand/ahp redstone_fever curefor server OPs. With no target, each affects the nearest live hamster within 16 blocks; pass an entity selector when the whole cave needs attention. Doesn't work on tamed hamsters, and admin cures won't grant advancements. - New Hamster Tips Guidebook Entries**
- Redstone Fever**
- Explains how to interrupt attacks with an Acorn Flute riff, and the **Musical Rodentry** entry gained a page hinting at how to get the new Acorn Music Disc.
- Acorn Flute**
- Explains how a riff distracts creepers and interrupts fevered hamsters, how to summon a hamster onto your shoulder, and how successful mounts train that hamster to respond faster.
- Hide & Seek Minigame**
- Explains the start message, hiding-place clues, time limit and reward so people don't keep asking me why their hamster disappeared lol.
- New Advancements**
- Redstone Fever**
- Discover a hamster suffering from Redstone Fever. Apparently prolonged redstone exposure has side effects.
- Flute-Assisted Recovery**
- Cure a fevered hamster with prolonged direct sunlight and good music. Medical licensing remains pending.
- The Final Note**
- Complete the Acorn Music Disc ritual with the same hamster you helped cure. Poetic. Legendary.
- Hide and Squeak**
- Find your hamster during a game of Hide & Seek before time runs out. Apparently this counts as responsible pet ownership.
### Changed
- Limited Sulking & Knocked Out States**
- Hamsters now recover from being knocked out or sulking within 10 seconds at most.
- I did this so you can more easily find your hamsters easier after throwing them. When they were permanently knocked out, they would never teleport to you in that condition.
- Teleport Rescue**
- My custom rescue code that brings following hamsters with you through all kinds of teleports is now silent and does not include particle effects. Its destination and delayed-spawn behavior remain unchanged. I just wanted to make sure it won't conflict with the new [**Void Hamster**](https://docs.google.com/document/d/1xlr4_pgvQ2KUDc4nyUVGhpClXSoFtABiVfZbJshMgps/edit?usp=sharing) coming in the next update.
- Long-distance rescue now cancels active minigames when the owner moves far enough away, while ordinary minigame behavior remains uninterrupted and commanded-sitting or bed-sleeping hamsters stay in place.
- Teleport Rescue now applies to hamsters that are knocked out and sulking. When they spawn next to you at the new location, they will be normal.
- Fast and Slow Hamster Dancing**
- Hamsters now bounce to Fast song matches and loop a new swaying animation to Slow matches. The existing
dancingMusicDiscStringssetting and all saved values remain the Fast list; the new Slow list defaults tolow-fiandzampoñaand wins when both lists match. For example, if a song name contained both “hamster” and “zampoña," a nearby hamster would do the slower dance. - Food Gets a Hamster's Attention**
- Every configured hamster food can now lure eligible hamsters, temporarily interrupting ordinary combat without
- Begging is reserved for taming food and shoulder-mount treats. Other food attracts them without the performance.
- Recipe Output Adjustments**
- Hamster Food Mix crafting now produces 4 Hamster Food Mix instead of 1.
- Acorn Composting**
- Acorns now compost more reliably, and now you can also compost Acorn Shards for a smaller but still useful contribution, and Acorn Hats provide the lowest contribution.

- The Symphonic Dairy advancement now displays its title instead of its translation key.
- Missing White & Pearl Rose Hamsters**
- If you've been exploring snowy biomes hoping to find pure white hamsters, you might have wondered why you were getting mostly blue and sky-colored hamsters instead. Snowy biomes were accidentally getting lumped into the "Icy" environment group, but they now correctly spawn with their intended snowy coat colors.
- This happened because the color-sorting system checks for Icy biomes before Snowy ones, and the Icy filter was accidentally set up to catch anything labeled as "snowy." Since snowy biomes got caught in the icy filter first, they were given icy blue palettes instead of white ones.
- If you've been looking for Pearl Rose hamsters in Magical Environments and couldn't find any, it wasn't just bad luck. A typo in the Magical Environment config names kept the settings from loading correctly, so Pearl Rose hamsters couldn't spawn there.
- Also cleaned up a few modded biome defaults and restored compatibility tag support so hamsters spawn properly across modded biomes.
- <font color="red">You'll need to restore a few worldgen config settings to get these fixes.</font> To opt into the corrected defaults without resetting your entire worldgen config, open the AHP config screen, go to **World Generation → Region-Based Color Filters**, and follow the exact reset locations below:

<font color="red">**IMPORTANT:**</font> If you've been looking for **White** or **Pearl Rose** hamsters and couldn't find them, this update fixes that— but **with one important condition:** you must follow the _**Missing White & Pearl Rose Hamsters**_ instructions down below (I colored it red) to manually restore the affected settings to their new defaults. Why? Because I didn't want to overwrite everyone's custom worldgen config settings in case some people have spent a lot of time on it.
### Added
- Redstone Fever**
- You might now come across rare wild aggressive cave hamsters with scars, glowing red eyes, rapid health regen, new animations, redstone particles, 3 new custom sound effect types, and unpredictable circular energy bursts. Thanks to [@The Retro Stitcher](https://theretrostitcher.com/) for the original Redstone Fever concept/idea!
- Currently, Redstone Fever is only applied when a hamster first spawns. Existing hamsters cannot contract it. I might add contagiousness in the future if it's requested.
- Food cannot tame, distract, or pacify an untreated hamster. You'll need to play a riff on the Acorn Flute to briefly interrupt its attacks while it keeps watching you with those red eyes. Lead it above redstone depth and keep it in direct clear sunlight for 3 Minecraft days to cure the condition and restore ordinary wild behavior.
- How do you lead it? You're the bait. Better find some good armor. For your toes.
- Spawning, sunlight treatment, aggression, bursts, and eligible dimensions are configurable. The Jade HUD overlay can optionally show Severe, Recovering, or Nearly Cured status if you enable it.
- Added a set of hidden config settings commissioned by the **After Beyond Networks** team for their upcoming "Ultimate Nightmare" event. These settings allow pre-existing wild hamsters to resolve one hidden surface-surprise roll when first approached by a player. Each result persists, so reloading or changing the chance cannot reroll the same hamster. These settings are purposefully hidden at the bottom of the config under "Commissioned Features." This changelog is the only place they will be mentioned.
- Acorn Flute & Acorn Music Disc**
- Thanks to [@The Retro Stitcher](https://theretrostitcher.com/) for the base Acorn Flute idea, the crafting recipes and the flute textures!
- Craft separate Lush, Ember, and Harmony Acorn Flutes from Acorn Shards, string, and pitcher plants or torchflowers. All three stack to 16 and share the same mechanics; the color is purely cosmetic at this stage, but does affect the color of the musical note particles.
- Play from your main hand to begin one of random riff sounds. You can play again right away to switch sounds. Switching items ends your active performance immediately. You can't play a flute if you aren't holding it. Duh. Different players can perform at the same time, so multiplayer flute incidents remain fully supported. I tried to make sure all the sounds were in E minor, but I'm not a music expert, lol.
- Server owners can turn up an Anti-Spam Cooldown that enforces a minimum wait between flute plays (config, just 0.5 seconds by default— I didn't want to punish your shaky aim if you intended to summon the hamster to your shoulder but missed the target and played a normal riff instead).
- Normal riffs can be heard up to 80 blocks away (very quiet) and distract threats within 16 blocks by default.
- You can distract creepers and fevered hamsters with the flute. Server owners can decide whether you should be able to calm all creepers or charged creepers only in the config.
- Fevered hamsters keep pursuing players while distracted, but won't attack or frantically sprint around in circles.
- Look directly at an owned hamster within 8 blocks while you have an open shoulder or head slot, and your flute will play a shorter chiff sound instead of the normal riff. The hamster will think about what that means, and then jump onto your shoulder. Successfully repeating this will train that exact hamster from a 3-second response toward 1 second after a configurable number of mounts (50 by default). A new optional Jade HUD line shows
Untrained,Learning,Responsive, orAttuned. I left it off by default since the Jade HUD is already getting crowded. - A flute-assisted sunlight cure qualifies that exact hamster for the Acorn Music Disc ritual. Tame it, mount it, then throw it at a charged creeper while any player's normal riff is actively calming the creeper. The qualified rescuer must make the killing throw; but failed attempts do not consume the qualification so if you can find another charged creeper you can try again.
- A successful ritual replaces the ordinary Cheese Music Disc drop with one Acorn Music Disc. It contains a fully licensed zampoña style version of the AHP theme song.
- Acorn Ring**
- Craft an Acorn Ring from an Acorn Hat and four Copper Ingots, or find one independently in uncommon loot chests.
- Wear it in your offhand with no extra mod, or in a ring slot through [**Accessories**](https://modrinth.com/mod/accessories)
[**Curios API**](https://modrinth.com/mod/curios) on Forge/NeoForge.
- When two players both wear a ring, their pets will not target the other player or pets that player owns—even in
- An offhand ring stays out of sight. Removing either ring ends protection without starting a fight.
- By default, the ring also keeps you from accidentally hitting your own pets. A separate setting can extend that
- Hamster Combat Timer**
- Standard-mode hamsters now abandon a fight after 30 seconds without relevant combat from their owner. Menace mode remains professionally unreasonable.
- Per-Hamster Armor Visibility**
- Each hamster inventory now has a compact checkbox for hiding that hamster's armor without removing its protection.
- Hamster Turning Animations**
- Idling hamsters now shuffle their paws and rock their body when rotating in place instead of gliding around like a robotic turntable.
- Hamster Reset Command**
- Added
/ahp reset_hamsterfor server OPs. It returns the nearest hamster to a freshly spawned wild state while
cooldowns, and other history get a clean slate.
- Redstone Fever Admin Commands**
- Added
/ahp redstone_fever applyand/ahp redstone_fever curefor server OPs. With no target, each affects the nearest live hamster within 16 blocks; pass an entity selector when the whole cave needs attention. Doesn't work on tamed hamsters, and admin cures won't grant advancements. - New Hamster Tips Guidebook Entries**
- Redstone Fever**
- Explains how to interrupt attacks with an Acorn Flute riff, and the **Musical Rodentry** entry gained a page hinting at how to get the new Acorn Music Disc.
- Acorn Flute**
- Explains how a riff distracts creepers and interrupts fevered hamsters, how to summon a hamster onto your shoulder, and how successful mounts train that hamster to respond faster.
- Hide & Seek Minigame**
- Explains the start message, hiding-place clues, time limit and reward so people don't keep asking me why their hamster disappeared lol.
- New Advancements**
- Redstone Fever**
- Discover a hamster suffering from Redstone Fever. Apparently prolonged redstone exposure has side effects.
- Flute-Assisted Recovery**
- Cure a fevered hamster with prolonged direct sunlight and good music. Medical licensing remains pending.
- The Final Note**
- Complete the Acorn Music Disc ritual with the same hamster you helped cure. Poetic. Legendary.
- Hide and Squeak**
- Find your hamster during a game of Hide & Seek before time runs out. Apparently this counts as responsible pet ownership.
### Changed
- Limited Sulking & Knocked Out States**
- Hamsters now recover from being knocked out or sulking within 10 seconds at most.
- I did this so you can more easily find your hamsters easier after throwing them. When they were permanently knocked out, they would never teleport to you in that condition.
- Teleport Rescue**
- My custom rescue code that brings following hamsters with you through all kinds of teleports is now silent and does not include particle effects. Its destination and delayed-spawn behavior remain unchanged. I just wanted to make sure it won't conflict with the new [**Void Hamster**](https://docs.google.com/document/d/1xlr4_pgvQ2KUDc4nyUVGhpClXSoFtABiVfZbJshMgps/edit?usp=sharing) coming in the next update.
- Long-distance rescue now cancels active minigames when the owner moves far enough away, while ordinary minigame behavior remains uninterrupted and commanded-sitting or bed-sleeping hamsters stay in place.
- Teleport Rescue now applies to hamsters that are knocked out and sulking. When they spawn next to you at the new location, they will be normal.
- Fast and Slow Hamster Dancing**
- Hamsters now bounce to Fast song matches and loop a new swaying animation to Slow matches. The existing
dancingMusicDiscStringssetting and all saved values remain the Fast list; the new Slow list defaults tolow-fiandzampoñaand wins when both lists match. For example, if a song name contained both “hamster” and “zampoña," a nearby hamster would do the slower dance. - Food Gets a Hamster's Attention**
- Every configured hamster food can now lure eligible hamsters, temporarily interrupting ordinary combat without
- Begging is reserved for taming food and shoulder-mount treats. Other food attracts them without the performance.
- Recipe Output Adjustments**
- Hamster Food Mix crafting now produces 4 Hamster Food Mix instead of 1.
- Acorn Composting**
- Acorns now compost more reliably, and now you can also compost Acorn Shards for a smaller but still useful contribution, and Acorn Hats provide the lowest contribution.
- Cycle Aggression States Without Sneaking**
- Configured Pacifist, Standard, and Menace items now change aggression through ordinary feeding.
- If the hamster is already in Standard aggression mode, configured sunflower seeds remain ordinary food.
- Flowers now equip as accessories with sneak + right-click, keeping normal right-click available for feeding.
- Instantly End Hamster Fights**
- Feeding your hamster a flower during a fight will instantly wipe its memory of the current target without enabling Pacifist mode.
- Trying to enable **Pacifist mode**? Just feed it a second flower while it is calm.
- Less Frequent Hide & Seek Games**
- Doubled the default initiation interval from roughly 3 minutes to roughly 6 minutes. *Existing worlds retain their
default.*
- Shoulder Hamster Throw Selection**
- Throwing now skips hamsters whose cooldown is still active and selects the next ready hamster in the configured
- Snowshoe Hamsters**
- Hamsters now walk on top of powdered snow instead of sinking in, and thrown hamsters land on the drift rather than vanishing into it. Hamsters are lightweights so it feels like it always should have been this way. Now your hamsters can comfortably watch you freeze to death.

# **The Punchy Patch**
In addition to a bunch of new mini-games, idle animations and QoL features (including hamster armor trims & toggleable aggression states!), this patch introduces 5 new super cute, first-person animations to your rodent-handling experience, courtesy of the amazing **Punchy mod!** I've been working closely with [**@Dev Punchy Man**](https://modrinth.com/mod/punchy-fpa) to overhaul how it feels to pick up, pet, yeet, and dismount your hamsters.
### 👉🏼 [**Showcase video**](https://www.youtube.com/watch?v=YGRdjOTCMHo) 👈🏼
### Added
- New First-Person Animations** _(Optional: Requires Punchy v2.6.0+)_
- Note: The Punchy mod is **not a required dependency** for Adorable Hamster Pets. It is only required if you want to experience these specific new first-person animations listed below:
- Petting/Tickling Animation** _(Requires Punchy v2.6.0+)_
- You can finally pet your hamster! If you stare affectionately at your hamster for a **while sneaking** (about 15 seconds on average), you might just reach down, pick it up and give it some tickles. Comes with a new animation where the hamster flips over on your hand and asks for a belly rub! Also added a dedicated "Pet Hamster" keybind (unbound by default) for when you don't feel like waiting for the random chance to kick in.
- For those with the patience of a fruit bat, pressing your "Pet Hamster" key or clicking your mouse will cancel the petting animation. You don't need to be sneaking to use the keybind.
- If the hamster was sitting before you picked it up to pet it, it will remain seated when you place it back down, making this a great way to manually re-position tamed hamsters around your base.
- Shoulder Mounting Animations** _(Requires Punchy v2.6.0+)_
- Luring a hamster to your shoulder is no longer a boring teleport. You will now physically lift them up, complete with the hamster adorably bouncing on your hands or running up your arm. Three new unique animations; dynamically changing depending on their destination (left shoulder, right shoulder, head).
- Hamster Yeet Animations** _(Requires Punchy v2.6.0+)_
- Holding down the throw key (
G) grabs a specific hamster off your shoulder and holds it in front of your face. _(For more info, see "Hamster Yeet Mechanics" below)._ - While queued up, the hamster also plays its own new animation _(Requires Punchy v2.6.0+)_ where it eagerly wiggles its butt and kicks its back feet in anticipation of being hurled through the air.
- Releasing the throw key (
G) executes the throw, which is immediately followed by a new Punchy animation where you wave goodbye to your furry projectile. - If you release the key before the short charging period (
15 ticks) is over, you safely abort the throw. Your character will politely place the hamster back onto the exact shoulder it came from. - Hamster Yeet Mechanics**
- The Yeet Queuing System**
- Throwing a hamster is no longer instant. You must hold down the throw key (
Gby default) to "queue" a hamster for throwing. Includes new animations if the Punchy mod is installed. _(for more info, see "New First-Person Animations" above)_. - Releasing the throw key (
G) executes the throw. - If you release the key before the short charging period (
15 ticks) is over, you safely abort the throw. This charging period of15 ticksis not configurable, due to its duration needing to match the Punchy mod's animation. But it's quite short— only0.75 seconds— so hopefully it won't impact gameplay. - Hamsters Weigh Less**
- Added a
Downward Force (Gravity)slider to the config, allowing you to fine-tune how far hamsters fly without needing to increase their initial thrust. - Reduced the default gravitational force by ~30%, so hamsters will fly a little bit further now. (Useful for recording hamster flights with the Flashback mod, which gets buggy when entities are moving very quickly through the air).
- FOV Zoom**
- Added a smooth FOV zoom effect while queueing the Hamster Yeet, identical to drawing a vanilla bow. This FOV zoom will help indicate the new charging period for anyone who doesn't have Punchy installed, since the new animations are part of Punchy.
- Cooldown Recovery**
- If you're impatient, feeding your hamster will now incrementally reduce its throw cooldown (similar to how feeding accelerates baby growth).
- More Feedback**
- A new action bar message will let you know when the hamster has recovered from its concussion and is ready for launch.
- More Flower Accessories**
- Expanded the old "Pink Petal" accessory. You can now equip **any flower in the
#flowerstag** onto your hamster instead of just Pink Petals. - There are 12 unique textures. The texture assignment logic automatically scans the registry names of flowers. It uses an extensive list of color keywords and botanical families to ensure almost any flower you apply (even modded flowers) will have the correct color palette.
- The color assignment logic is completely data-driven. You can easily force a modded flower to use a specific color palette using standard Minecraft Item Tags (e.g., adding an item to
#adorablehamsterpets:flower_accessories/overlay_wither_rose). - For a tutorial, pop over to [**The Cheek Pouch**](https://discord.gg/w54mk5bqdf) Discord server, visit the **FAQ channel**, and search for _Custom Flower Accessories._
- Added new pages to the *Hamster Tips* guidebook explaining how the dynamic color assignment and tag overrides work.
- Shader LabPBR Material Support**
- All items, blocks, particles, and entities in this mod now include their own LabPBR-compliant Specular and Normal textures (with hamsters generating theirs procedurally), giving them detailed, per-layer PBR effects (emission, subsurface scattering, specular reflections, porosity, etc.) out-of-the-box with supported shaders.
- Must have your shader's material settings set to "LabPBR" or "Hardcoded + LabPBR"
- Metal armors have a "Vanilla-inspired" glossiness by default, but if you prefer hardcore realism and want them super metallic/reflective, I added custom sliders in the config allowing you to manually fine-tune the PBR values for each individual armor type.
- Added a
Max POM Depthslider to allow fine-tuning of the procedural 3D fur displacement (only works if your shader supports POM on entities, which is extremely rare). - Armor Trims**
- Hamster Armor can now be customized with vanilla armor trims in the Smithing Table.
- The following trims are currently available: Coast, Border, Vex, Eye, Sentry, Wild
- They will naturally glow in the dark and automatically have emission with shader mods like Iris.
- Added an
Emissive Armor Trimstoggle in the client config so you can disable the glowing effect if you hate fun and prefer a non-luminescent reality. - Added a
Trim Emissive Brightnessslider to give you precision control over exactly how blinding the neon lines should be. - Configurable Aggression States**
- Hamsters now have three distinct aggression states controlled by their diet.
- Pacifist:** Sneak + right-click them any vanilla flower (e.g.,
#minecraft:flowers). They become total hippies and will refuse to attack anything, even if you are being actively mauled. - Standard:** Sneak + right-click them Sunflower Seeds to factory-reset them back to their normal, wolf-like defensive behavior.
- Menace:** Sneak + right-click them a Spider Eye to unleash their inner demon. They will actively hunt down anything on the configurable "Menace Targets" list (which defaults to all monsters and bosses), and gain an expanded follow radius to give them more room to fight. If a target is outside their follow radius, they will move frantically at the edge of the tether.
- All trigger items are fully configurable, and changing a hamster's state produces a visual and audio confirmation.
- If you have jade installed, its overlay will display the hamster's current Aggression State when it is set to something other than the default, and can be toggled in the config alongside the other genetic displays.
- Hamster Tips Guidebook Entry**
- The *Hamster Tips* guidebook now features a dedicated "Aggression States" page to explain the new mechanics. It utilizes dynamic text injection to accurately display your configured trigger items, ensuring the book is always up-to-date even if a modpack creator changes the required diets.
- Pacifist Break:** Added a
Pacifist Break on Attackconfig toggle (false by default). When enabled, a passive hamster will automatically revert to neutral if it sees you attacking something. - Crop Harvesting**
- Tamed, wandering hamsters now possess an irrepressible desire for the occasional midnight snack.
- If they find a fully mature crop nearby and they have room in their cheek pouch, they will violently pounce on it, aggressively stuff the harvest into their cheek pouches, and accidentally replant some seeds in the process.
- Includes dynamic block particles and a leaf-crunching sound effect when pouncing on the crop block.
- Includes dynamic item particles when the hamster scoops up the dropped seeds and harvest items.
- Added a new
Crop Snacking Settingsallowing you to disable the feature entirely, tweak the cooldown, or add specific crops from their menu. - Added a new custom
#adorablehamsterpets:crop_itemsunion tag so hamsters can recognize and eat/harvest most modded crops and vegetables out of the box. - Added two new "Crop Harvesting" pages to the *Hamster Tips* guidebook explaining the feature.
- Swimming Mechanics**
- Added a new swimming animation loop for hamsters that accidentally fall into the water. This seems to happen a lot when they are snacking on crops so I thought it was a good time to add it.
- Replaced the Vanilla game's erratic swimming AI with a custom, smoother physics simulation that doesn't launch them out of the water every couple of seconds like a dolphin.
- Included 7 new unique water-swishing sound effects as part of the swimming animation.
- Hamsters can now dive underwater in persuit of items they want to steal/snack on.
- They will still do their best to avoid water the rest of the time, but now they don't look so broken when they inevitably fall into it.
- Hide & Seek Mini-Game**
- Tamed hamsters now occasionally get the urge to disappear into the woodwork.
- If they find a suitable hiding spot (bushes, chests, barrels, etc.), they will leap into it and vanish.
- You have a limited time to find them (configurable, ~45-60 seconds by default) before their short attention span gets the better of them. If you try to break or interact with the block they are hiding in during that time, you win! They will pop out and reward you with an item from their cheek pouches.
- If the timer runs out before you find them, they will emerge, sulk, and you get nothing.
- The block they are hiding in will occasionally jiggle, make noise, and spawn particles to help you locate them.
- You will also see a trail of subtle particles from your location directly towards the hiding spot, provided you are within 25 blocks of the hidden hamster.
- These effects will be *very* scarce at the start, but dynamically increases in frequency/intensity as the game progresses.
- Configurability:** Everything is customizable in the config. You can adjust the initiation chance, duration, block lists, and whether they are allowed to hide inside storage blocks like chests.
- Storage Crates**
- Thanks to [**@The Retro Stitcher**](https://theretrostitcher.com/) for helping to design new compacting storage crates for Acorns, Cucumbers, Green Beans, and Hamster Food Mix.
- Fully compatible with LabPBR shader materials out-of-the-box.
- "Hamtaro" Easter Egg**
- Renaming a hamster "Hamtaro" gives it a special texture. This functions identically to the "Sweet Potato" easter egg. Both base textures provided by [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com)!
- New "Panda" Overlay Pattern**
- Added a new "Panda" fur overlay pattern to the genetics engine, allowing you to breed panda-like hamsters. To get a "Panda" hamster, you'll need a Black base coat and a white overlay with the new "Panda" pattern. These can't be found in the wild, since black hamsters do not spawn with white overlays in the wild (breaks their camouflage). Thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for the Panda inspiration!
- 3 New Music Discs & Hamster Dancing**
- A legendary new **Cheese Music Disc** featuring the Adorable Hamster Pets theme song, created by yours truly. Can only be obtained by orchestrating a high-velocity, terminal collision between an airborne hamster and a Charged Creeper.
- Alternate Versions**
- The **Parmesan Music Disc:** Features an Orchestral remix of the Adorable Hamster Pets theme song. Piglins are apparently lactose aficionados. Trade a regular Cheese Music Disc with a Piglin to receive this highly adventurous, grated alternative.
- The **Blue Cheese Music Disc:** Features a Low-Fi remix of the Adorable Hamster Pets theme song. Obtainable by tossing a regular Cheese Music Disc into the End exit portal after defeating the dragon. The void will age the cheese and violently spit it back out at you.
- ⚠️ **Content Creators ↓**
- All three songs are **fully licensed** and safe for YouTube & Twitch monetization. Feel free to feature them in your videos!
- If playing in a Jukebox, nearby hamsters will dance to the music.
- Tried one of the remixes but not a fan? Surround the Blue Cheese or Parmesan discs with regular Cheese in a crafting table to restore them to their original 8-Bit glory.
- Added new advancements and guidebook pages hinting about how to obtain them.
- Modded Music Disc Support**
- Added a
Dancing Music Discsstring list in the config that contains a few strings by default:hamster,hampter, andhamtaro. If a jukebox plays a music disc containing any of these configured strings in its name, description, or lore (case-insensitive), nearby hamsters will dance to it. - Inter-Hamster Tag Mini-Game**
- Hamsters will now spontaneously instigate games of tag with each other.
- The instigator will sprint up to an unsuspecting victim, deliver a visual (damage-free) slap (using a new cowbell sound effect), and sprint away to begin the chase.
- If the chaser catches the instigator or if the 15-second timer runs out, the game ends and both hamsters celebrate.
- Tethering:** The instigator dynamically restricts its flee path to stay within 14 blocks of you (if tamed), ensuring they don't sprint off a cliff or into an unloaded chunk during the heat of the chase.
- Player Interruption:** Right-clicking either hamster while they are playing tag with each other will instantly break up the game and send them back to their normal routines, but will not reward you with a gift.
- Population-Independent Rarity:** The probability math dynamically adjusts based on the local hamster population. Whether you have 2 hamsters in your base or an apocalyptic horde, you will only see an average of 1 game per minute in that area.
- Configurability:** Added
Enable Hamster-vs-Hamster Tag,Average Minutes Between Games, andInter-Hamster Tag Durationsettings to the config. - New Ambient Sitting Animation**
- Added a new "sitting roll" animation where sitting hamsters occasionally roll on their backs. Comes with new sound effects, and it's configurable in the new "Ambient Sitting Behaviors" config group, which also controls cleaning frequency.
- Includes a "Cartoon Rolling Sound" config toggle. By default, the hamster's rolling SFX will include a cartoon-ish slide whistle. It's subtle, but some people might get distracted easily or prefer more realism.
- Hamster Armor Template Duplication**
- Hamster Smithing Templates can now be duplicated on a crafting table!
- Use 1 Template (top center), 1 corresponding material ingot/gem (center), and 7 Acorn Shards.
- Botanical Vandalism (Sapling Trimming)**
- You can now right-click any sapling with a pair of Shears to instantly turn it into a Dead Bush. This provides a much more accessible way to gather the necessary materials for crafting Hamster Bedding if you don't live near a desert.
- Added a new page to the *Hamster Tips* guidebook detailing this mechanic.
- Free Bed Respawn Toggle**
- Added a config toggle to allow hamsters to respawn at their linked beds indefinitely without requiring a tribute item charge (like a Totem of Undying). Disabled by default.
- Dynamic Trees Compatibility**
- Added out-of-the-box support for [**Dynamic Trees**](https://modrinth.com/mod/dynamictrees) via some new config settings.
- Replaced hardcoded oak leaves checks with a new
Heistable Leaveslist in the config, allowing modpack makers to easily add other modded leaves or trees to the heist feature. - Added a new
Heistable Logslist to theTree Heist Settingsconfig, similar to theHeistable Leaveslist. This means you can now start a tree heist by throwing the hamster at a branch or the trunk. - Developed a dumber but more compatible canopy-mapping algorithm that activates automatically if
Dynamic Treesis installed, ensuring heist still works without the vanilla leaves' internaldistance from trunkproperty. - Acorn Note:** The Dynamic Trees mod adds their own type of acorns and drop methods. When that mod is installed, the only way to get the specific acorns from my mod is through the Tree Heist.
- Dehydration and NutritionZ Compatibility**
- Added built-in datapacks for the [**Dehydration**](https://modrinth.com/mod/dehydration) and [**NutritionZ**](https://modrinth.com/mod/nutritionz) mods. Cucumbers will now hydrate you, and Cheese will finally clog your arteries properly.
- Combustible Acorns**
- Acorns can now be used as furnace fuel, smelting exactly the same amount of items as a vanilla stick.
- Alternatively, placing an Acorn in the top slot of a furnace will smelt it down into a piece of Charcoal.
- World Gen Compatibility Enhancements**
- Added massive out-of-the-box biome compatibility configuration data for [**Oh The Biomes We've Gone**](https://modrinth.com/mod/oh-the-biomes-weve-gone), ensuring hamster variants properly disperse across their beautiful landscapes. Huge thanks to [**@jlk2003r**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for helping configure these lists!
- Create Mod Compatibility**
- Added out-of-the-box recipe compatibility for [**Create: Bitterballen**](https://modrinth.com/mod/create-bitterballen) and [**Create Crafts & Additions**](https://modrinth.com/mod/createaddition).
- You can now mill, crush, compact, roast, and smoke AHP Sunflower Seeds to progress through the Bitterballen tech tree seamlessly, bypassing the need to hunt down vanilla sunflowers. Thanks to [**@jlk2003r**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for teaching me about Create so I knew what recipes to add!
- Armor Tier Jumping**
- You can now upgrade Hamster Armor between any tiers using the Smithing Table (e.g., Iron to Diamond, Diamond to Netherite). Previously, all upgrades had to start from base Acorn Armor. You can also downgrade it... should you decide to do so.
- Infinite Bed Respawns**
- Added a new
Tribute One-Time Useconfig setting. When enabled, a bed only requires the tribute item (Totem of Undying by default) once, permanently unlocking infinite respawns for that specific bed and hamster. - Taming Feedback**
- The mod will now provide snarky chat feedback if you try to tame a hamster incorrectly (such as not sneaking or offering them the wrong food) and will point you to the guidebook for help.
- Hamster Bed Placement Safeguard**
- Unlinked hamster beds can no longer be placed in the world accidentally.
- Attempting to do so for the first time triggers an audible warning and chat message explaining that they must be linked to a hamster first.
- After receiving the warning, a 2-second cooldown begins. Once it expires, players are allowed to place the unlinked bed freely. The game remembers that you've been warned and won't bother you again.
- Added config settings under 'Hamster Beds & Wander Mode' to disable the warning entirely, or to clear your history so you can experience it all over again.
- The tooltips and guidebook entries have been updated to make the linking process ("right-click a hamster with bed in hand") much clearer.
- Global Notification Toggle**
- Added a
Server Disable Announcementsconfig setting. Server owners can now globally disable the notification bell icon for all connected players. - Smoker Support**
- Green Beans can now be cooked into Steamed Green Beans using a Smoker, which cooks them twice as fast as a standard furnace.
- Compostable Sunflowers**
- The custom Adorable Hamster Pets Sunflower can now be placed in a composter (matching the 65% compost chance of vanilla sunflowers).
- Plantable Acorns**
- Acorns can now be planted directly on dirt/grass to grow vanilla Oak Trees. Once placed they will become Oak Saplings.
### Changed
- Config GUI Major Overhaul**
- During development on v3.6.1, the mod's configuration file exceeded Minecraft's hard-coded networking limits due to a Fzzy Config NeoForge bug which I've already reported. As a work-around, the main config has been split into multiple smaller, organized configs. It needed to be done anyway, so I simultaneously re-organized everything, making it more intuitive to navigate.
- Dismount Keybinding Simplification**
- Removed the confusing config toggle that forced players to enable a custom keybind in the config before they could rebind the "Dismount Hamster" key in the
Controls > Key Bindsmenu. The keybind is now permanently exposed. - The "Dismount Hamster" keybind now utilizes an unbound fallback system. By default, the keybind is set to
Unbound, and the game will naturally listen to your vanillaSneakkey to dismount hamsters. However, if you manually assign a key to it in the controls menu, it will override the sneak behavior and listen exclusively to your custom key. - The default "Button-Press Behavior" config setting has been changed from
Single PresstoDouble Tapto prevent accidental dismounts when sneaking near ledges. Originally it was set to single press to mimic vanilla parrot behavior, but it's just so annoying. I finally can't stand it anymore. Lol. - Added a
Custom Key Behavior Overrideconfig toggle (true by default). When you bind a custom key for dismounting, it automatically overrides theDouble Tapbehavior and makes it aSingle Press. I assume if you assigned a dedicated key to it, you don't want to have to tap it twice. - Keybind Names**
- Renamed several of the key binds to make the
Controls > Key Bindsmenu more intuitive. - Hamster Attacking AI**
- Hamsters can no longer pathfind outside the follow radius when targeting entities. They will instead exhibit erratic behavior near the edge of the boundary.
- This prevents repetitive teleportation back to the player when the hamster is aggressively targeting something outside the follow distance.
- To compensate, follow distance has been increased by five blocks when the hamster is in MENACE mode.
- The Hamster Yeet**
- Throwing a hamster is no longer canceled/prevented if the player's crosshair is over non-solid blocks like tall grass, flowers, sugar cane etc.
- Reduced the default gravity applied to thrown hamsters by 30%, resulting in naturally longer, flatter arcs out-of-the-box. Hamsters will feel less "heavy" now during throws.
- Thrown hamsters now generate a shower of block-breaking particles upon impacting a surface.
- Resolved an issue where players throwing their hamsters very far away wouldn't hear some of the animation-based impact sounds due to vanilla audio distance attenuation.
- Hamster Tips Guidebook**
- "The Great Escape" has been renamed to "Beds & Wander Mode," and "Acorn Armor" has been renamed to "Tree Heist & Armor" so you guys won't keep coming into my Discord server asking how the beds work and where to find acorns 😂
- This has another super useful perk: Now whenever you search through the guidebook for a specific topic, you can search for things like "bed," "tree heist," or "armor" and those specific entries will pop up in the results.
- Now utilizes dynamic text injection to accurately display your configured resurrection tribute items. So now if a server owner or modpack creator changes the default item from a Totem of Undying, the guidebook will update itself automatically.
- Tag Mini-Game**
- Wild hamsters can no longer initiate a game of tag to prevent interference with taming. Tamed hamsters can still play tag with strangers if enabled in the config.
- The game will no longer randomly start while you are sneaking, preventing interference with petting.
- You can now manually start a game of tag on-demand by rapidly sneaking and un-sneaking while maintaining eye contact with a tamed hamster.
- Since there is now a manual trigger, the chance of the game starting is now much lower. You will need to stare at a hamster for ~15 seconds on average for the game to automatically start.
- Starting a game of tag now plays a sound, spawns particles, and displays an action bar message to clearly indicate that it is a fun event and not a bug.
- Hamsters will now lovingly slap you (applying knockback and brief nausea, but no damage) when the game starts.
- Added a 1-second interaction cooldown when the game starts to prevent accidentally catching the hamster immediately.
- Genetics & Color Groups**
- Renamed the
ROSEcolor group toCHERRYsince the only hamster in that group is the "Pearl Rose" hamster, which is basically pink anyway. - Added a new
RUSTcolor group. The "Rust" hamster has officially been evicted from theORANGEcategory, allowing it to have its own dedicated spawning rules. - Spawning Config Overhaul**
- Reorganized the World Gen config UI to clearly separate the global "Allow/Prevent Spawns" lists from the "Region-Based Color Filters". It now clearly explains the "filter funnel" concept so you know exactly why the Plains environment acts as a catch-all.
- Expanded the procedural spawning logic from 10 environments to 12, giving modpack makers perfect 1:1 granular control over all 12 hamster color groups.
- The Wildcard:** Added a "Priority 1: Wildcard" zone. Allows server owners to surgically extract specific biomes from broader categories and assign them unique colors without overhauling the other lists. (i.e., If you wanted to separate the environments in which Light Gray and Dark Gray hamsters spawn, now you can do so).
- Sky Environments:** Added a dedicated zone for floating island biomes to host the
SKYcolor group. Vanilla players— no need to freak out; there's still a 15% chance to findSKYhamsters instead ofWHITEin snowy areas. - Cherry Environments:** Extracted Cherry Groves out of the Magical environments so they can be balanced independently. Defaults to 100%
CHERRYhamsters. - Auburn Environments:** Added a dedicated zone targeting Badlands (and modded autumnal forests with red trees if you like). This is the exclusive new home for
RUSThamsters. (ORANGEhamsters will no longer spawn in Badlands by default). - Re-balanced Weights:** Adjusted the default spawning weights across the
Icy,Magical, andSnowyenvironments to accommodate the new color zones. - ⚠ Important Config Note for Existing Worlds**
- If you are updating an existing modpack, your old config files will obstinately hold on to their old settings. This is good, otherwise you would lose all your work every time I pushed out an update. However, this means that in order to see these new default spawn weights, you will need to right-click specific settings in the config screen and select "Restore Defaults." Alternatively, click the "Changes" button (bottom-right corner) and click "Restore Defaults" to reset everything at once (only affects the config from my mod).
- Hamster Bedding Leaf Particles**
- Doubled the visual size of the Hamster Bedding particles to better match the leaves on the trees and on the hamster bed itself.
- Pink Petal Accessories**
- Added a new config toggle (true by default) to dynamically render Pink Petal accessories on the outside of equipped armor, so your hamster can be safe and fabulous simultaneously.
- Configurable 3D Visualizer Particles**
- Added a
Continuous Genetics Cylindertoggle to the config. When disabled, the 3D bounding cylinder generated by/ahp spawn_all_bases_3Dwill only render for the first second after spawning to reduce clutter. - Spawning & Testing Commands**
- Added
/ahp undo_last_spawn. Easily discards all hamsters spawned by your very last/ahp spawn...command. Perfect for when you set up a hamster display and then accidentally run the 2-million permutation command in the wrong location. - Overhauled the
/ahp spawn_all_possible_permutations_THIS_CAN_BREAK_YOUR_WORLDcommand. It is now called/ahp spawn_random_group <count>. - You must now provide a
<count>argument. It accepts standard numbers (e.g., 500) or anall_THIS_CAN_BREAK_YOUR_WORLDstring. - Hamsters are now spawned in a completely randomized order and placement on the grid.
- If the requested count is 5,000 or less, the hamsters are spawned synchronously and instantly without invoking the asynchronous batch-spawning system.
- Added five additional optional arguments to the 2D, 3D, and randomized spawn commands:
[spacing_multiplier],[match_player_yaw],[randomize_sitting],[randomize_sleeping], and[randomize_yaw]. These arguments allow you to expand or shrink the physical distance between the spawned hamsters, force the entire grid of spawned hamsters to face one direction, a random direction, and/or give them static poses to keep things more visually interesting. - Added a new argument to the
/ahp spawn_random_groupcommand calleduse_wild_overlay_rules_for_breeding_overlays. Allows you to spawn a more realistic/natural looking random group of hamsters. - Added a new
<pose>argument to the/ahp spawn hamstercommand, allowing you to specify sitting, sleeping, idle, or none. - Added personality ID's for command-spawned hamsters. The random sitting/sleeping poses are based on that ID, so they will retain those poses even after being tamed.
- Updated the
Admin Commandschapter in the *Hamster Tips* guidebook to include descriptions for these new commands and arguments. - Hamster Bed Placement**
- Placing down a new hamster bed no longer forces the hamster to sleep in it immediately unless the conditions are correct (i.e., time of day, config settings).
- Wandering Hamster Sitting**
- Hamsters linked to a bed will no longer automatically sit down when their owner logs out or changes dimensions, as long as the bed is still intact.
### Fixed
- Hamsters Falling Into End Portals**
- Hamsters that wander into the exit End Portal will now bounce right back out, complete with particle and sound effects.
- Prevents them from teleporting to the Overworld spawn coordinates and getting lost.
- Added a toggle to the config to revert to standard vanilla behavior if desired.
- Hamster Yeet & Evilcraft Bug**
- Resolved an bug that prevented hamsters from being thrown on Forge and NeoForge dedicated servers, caused by environment annotations running on the server thread. Super niche little insect that slipped by because it doesn't exist on Fabric. You should be able to throw your hamsters in multiplayer again!
- This also resolves a server startup crash when playing with EvilCraft, which attempts to instantiate the projectile to check its blood levels. Lol.
- Food Item Stacking**
- Resolved an issue on 1.21.1 where the configurable food items became unstackable in the inventory GUI after being split or spread.
- Implemented a stable ComponentMap caching system to ensure GUI right-click dragging correctly identifies dynamic food stacks as equal.
- Sliced Cucumber Feeding**
- Resolved a bug where already-tamed hamsters would refuse to eat their taming food (e.g. Sliced Cucumber) to heal or breed.
- Projectile Accessories**
- Fixed a visual bug where a hamster's equipped armor and accessories would temporarily vanish while they were airborne during a throw.
- Server Performance**
- Resolved a few pathfinding and AI issues where tamed hamsters following the player would sometimes experience server-tick lag spikes. Usually you wouldn't notice these unless you had a lot of hamsters following you at once.
- Wander Mode Override**
- Resolved a bug where disabling Wander Mode in the global config wouldn't stop already-wandering hamsters from lingering around their beds.
- Cheese Item Texture**
- Finally fixed the 99% transparent pixel in the bottom left corner of the cheese item texture. I only recently realized what was causing it to look so strange. Lol
- Console Log Spam**
- Resolved an issue where players with internet disabled (or those playing in regions where GitHub is blocked) would receive a massive, screen-filling error stack trace in their console every 5 minutes when the mod silently checked for updates in the background. Background network failures are now politely logged as a single warning line.
- Resolved an issue where the genetics engine would spam the server console with warnings when attempting to generate wild overlays for hamsters with extremely bright base coats (like Coconut).
- Sweet Potato Easter Egg**
- Renaming a hamster to "Sweet Potato" now correctly applies the easter egg texture without accidentally deleting the hamster's eyes, skin layer, and accessories. So that's good.
- Resolved an issue where the effects would trigger immediately upon renaming a hamster via the GUI, before the screen was closed.
- Resolved an issue where the affects would not trigger at all on 1.20.1 if a hamster was renamed via the GUI.
- Missing Vanilla Tags**
- The custom AHP Sunflower block is now properly registered under the vanilla
#minecraft:flowersand#minecraft:tall_flowerstags. This resolves compatibility issues with mods like Alex's Mobs that rely on these tags to identify flowers in the world. - Flashback Mod**
- Resolved a server crash that occurred when scrubbing through replay timelines using the Flashback mod, caused by missing NBT data on Hamster Beds.
- Resolved a persistent desync issue where shoulder hamsters would disappear when scrubbing backwards or jumping to different points on the replay timeline. Future replays will hopefully be fixed via a periodic server-side data sync that runs once per second.
- File Parsing Crashes**
- Fixed a crash that occurred when reading corrupted
.jsoncache files for the supporter perk system. It will now safely ignore the corrupted file and download a fresh copy from the internet. - Guidebook Server Synchronization**
- Resolved an issue where the "Missing Guidebook" chat warning would trigger repeatedly across multiple game sessions when playing on a dedicated server due to a configuration synchronization flaw.
- Fixed an issue where players were falsely led to believe they could locally disable Guidebook Auto-Delivery on dedicated servers. These settings now properly sync from the server to the client's config UI, reflecting the server's true authority over the book's delivery.
- Food Interactions**
- Fixed a bug where players could not toggle their hamster's sitting state if they were holding Hamster Food Mix or other food items.
- "Hampter"** Custom Name
- The "Use 'Hampter' as Default Name" config setting now properly reflects on the Jade HUD overlay and the Hamster Inventory screen.
- Cheek Pouch Allowed Items**
- Fixed an issue where all vanilla food items were forbidden in the Cheek Pouch on 1.20.1 due to a typo.
- Spawn Commands**
- Resolved an issue where AI-disabled hamsters generated by
/ahp spawn_all_bases_3Dwould sometimes suffocate and die if they spawned inside each other. They are now completely invulnerable until they are tamed/woken up. - Cheek Pouch Desync**
- Fixed an issue where a hamster's cheek pouches would visually deflate in heavily modded environments due to partial NBT syncing from mods like Jade.
- Guidebook Recovery Routing**
- The "Missing Guidebook" chat warning now correctly opens the root configuration menu so the recovery button is actually visible.

# **The Punchy Patch**
In addition to a bunch of new mini-games, idle animations and QoL features (including hamster armor trims & toggleable aggression states!), this patch introduces 5 new super cute, first-person animations to your rodent-handling experience, courtesy of the amazing **Punchy mod!** I've been working closely with [**@Dev Punchy Man**](https://modrinth.com/mod/punchy-fpa) to overhaul how it feels to pick up, pet, yeet, and dismount your hamsters.
### 👉🏼 [**Showcase video**](https://www.youtube.com/watch?v=YGRdjOTCMHo) 👈🏼
### Added
- New First-Person Animations** _(Optional: Requires Punchy v2.6.0+)_
- Note: The Punchy mod is **not a required dependency** for Adorable Hamster Pets. It is only required if you want to experience these specific new first-person animations listed below:
- Petting/Tickling Animation** _(Requires Punchy v2.6.0+)_
- You can finally pet your hamster! If you stare affectionately at your hamster for a **while sneaking** (about 15 seconds on average), you might just reach down, pick it up and give it some tickles. Comes with a new animation where the hamster flips over on your hand and asks for a belly rub! Also added a dedicated "Pet Hamster" keybind (unbound by default) for when you don't feel like waiting for the random chance to kick in.
- For those with the patience of a fruit bat, pressing your "Pet Hamster" key or clicking your mouse will cancel the petting animation. You don't need to be sneaking to use the keybind.
- If the hamster was sitting before you picked it up to pet it, it will remain seated when you place it back down, making this a great way to manually re-position tamed hamsters around your base.
- Shoulder Mounting Animations** _(Requires Punchy v2.6.0+)_
- Luring a hamster to your shoulder is no longer a boring teleport. You will now physically lift them up, complete with the hamster adorably bouncing on your hands or running up your arm. Three new unique animations; dynamically changing depending on their destination (left shoulder, right shoulder, head).
- Hamster Yeet Animations** _(Requires Punchy v2.6.0+)_
- Holding down the throw key (
G) grabs a specific hamster off your shoulder and holds it in front of your face. _(For more info, see "Hamster Yeet Mechanics" below)._ - While queued up, the hamster also plays its own new animation _(Requires Punchy v2.6.0+)_ where it eagerly wiggles its butt and kicks its back feet in anticipation of being hurled through the air.
- Releasing the throw key (
G) executes the throw, which is immediately followed by a new Punchy animation where you wave goodbye to your furry projectile. - If you release the key before the short charging period (
15 ticks) is over, you safely abort the throw. Your character will politely place the hamster back onto the exact shoulder it came from. - Hamster Yeet Mechanics**
- The Yeet Queuing System**
- Throwing a hamster is no longer instant. You must hold down the throw key (
Gby default) to "queue" a hamster for throwing. Includes new animations if the Punchy mod is installed. _(for more info, see "New First-Person Animations" above)_. - Releasing the throw key (
G) executes the throw. - If you release the key before the short charging period (
15 ticks) is over, you safely abort the throw. This charging period of15 ticksis not configurable, due to its duration needing to match the Punchy mod's animation. But it's quite short— only0.75 seconds— so hopefully it won't impact gameplay. - Hamsters Weigh Less**
- Added a
Downward Force (Gravity)slider to the config, allowing you to fine-tune how far hamsters fly without needing to increase their initial thrust. - Reduced the default gravitational force by ~30%, so hamsters will fly a little bit further now. (Useful for recording hamster flights with the Flashback mod, which gets buggy when entities are moving very quickly through the air).
- FOV Zoom**
- Added a smooth FOV zoom effect while queueing the Hamster Yeet, identical to drawing a vanilla bow. This FOV zoom will help indicate the new charging period for anyone who doesn't have Punchy installed, since the new animations are part of Punchy.
- Cooldown Recovery**
- If you're impatient, feeding your hamster will now incrementally reduce its throw cooldown (similar to how feeding accelerates baby growth).
- More Feedback**
- A new action bar message will let you know when the hamster has recovered from its concussion and is ready for launch.
- More Flower Accessories**
- Expanded the old "Pink Petal" accessory. You can now equip **any flower in the
#flowerstag** onto your hamster instead of just Pink Petals. - There are 12 unique textures. The texture assignment logic automatically scans the registry names of flowers. It uses an extensive list of color keywords and botanical families to ensure almost any flower you apply (even modded flowers) will have the correct color palette.
- The color assignment logic is completely data-driven. You can easily force a modded flower to use a specific color palette using standard Minecraft Item Tags (e.g., adding an item to
#adorablehamsterpets:flower_accessories/overlay_wither_rose). - For a tutorial, pop over to [**The Cheek Pouch**](https://discord.gg/w54mk5bqdf) Discord server, visit the **FAQ channel**, and search for _Custom Flower Accessories._
- Added new pages to the *Hamster Tips* guidebook explaining how the dynamic color assignment and tag overrides work.
- Shader LabPBR Material Support**
- All items, blocks, particles, and entities in this mod now include their own LabPBR-compliant Specular and Normal textures (with hamsters generating theirs procedurally), giving them detailed, per-layer PBR effects (emission, subsurface scattering, specular reflections, porosity, etc.) out-of-the-box with supported shaders.
- Must have your shader's material settings set to "LabPBR" or "Hardcoded + LabPBR"
- Metal armors have a "Vanilla-inspired" glossiness by default, but if you prefer hardcore realism and want them super metallic/reflective, I added custom sliders in the config allowing you to manually fine-tune the PBR values for each individual armor type.
- Added a
Max POM Depthslider to allow fine-tuning of the procedural 3D fur displacement (only works if your shader supports POM on entities, which is extremely rare). - Armor Trims**
- Hamster Armor can now be customized with vanilla armor trims in the Smithing Table.
- The following trims are currently available: Coast, Border, Vex, Eye, Sentry, Wild
- They will naturally glow in the dark and automatically have emission with shader mods like Iris.
- Added an
Emissive Armor Trimstoggle in the client config so you can disable the glowing effect if you hate fun and prefer a non-luminescent reality. - Added a
Trim Emissive Brightnessslider to give you precision control over exactly how blinding the neon lines should be. - Configurable Aggression States**
- Hamsters now have three distinct aggression states controlled by their diet.
- Pacifist:** Sneak + right-click them any vanilla flower (e.g.,
#minecraft:flowers). They become total hippies and will refuse to attack anything, even if you are being actively mauled. - Standard:** Sneak + right-click them Sunflower Seeds to factory-reset them back to their normal, wolf-like defensive behavior.
- Menace:** Sneak + right-click them a Spider Eye to unleash their inner demon. They will actively hunt down anything on the configurable "Menace Targets" list (which defaults to all monsters and bosses), and gain an expanded follow radius to give them more room to fight. If a target is outside their follow radius, they will move frantically at the edge of the tether.
- All trigger items are fully configurable, and changing a hamster's state produces a visual and audio confirmation.
- If you have jade installed, its overlay will display the hamster's current Aggression State when it is set to something other than the default, and can be toggled in the config alongside the other genetic displays.
- Hamster Tips Guidebook Entry**
- The *Hamster Tips* guidebook now features a dedicated "Aggression States" page to explain the new mechanics. It utilizes dynamic text injection to accurately display your configured trigger items, ensuring the book is always up-to-date even if a modpack creator changes the required diets.
- Pacifist Break:** Added a
Pacifist Break on Attackconfig toggle (false by default). When enabled, a passive hamster will automatically revert to neutral if it sees you attacking something. - Crop Harvesting**
- Tamed, wandering hamsters now possess an irrepressible desire for the occasional midnight snack.
- If they find a fully mature crop nearby and they have room in their cheek pouch, they will violently pounce on it, aggressively stuff the harvest into their cheek pouches, and accidentally replant some seeds in the process.
- Includes dynamic block particles and a leaf-crunching sound effect when pouncing on the crop block.
- Includes dynamic item particles when the hamster scoops up the dropped seeds and harvest items.
- Added a new
Crop Snacking Settingsallowing you to disable the feature entirely, tweak the cooldown, or add specific crops from their menu. - Added a new custom
#adorablehamsterpets:crop_itemsunion tag so hamsters can recognize and eat/harvest most modded crops and vegetables out of the box. - Added two new "Crop Harvesting" pages to the *Hamster Tips* guidebook explaining the feature.
- Swimming Mechanics**
- Added a new swimming animation loop for hamsters that accidentally fall into the water. This seems to happen a lot when they are snacking on crops so I thought it was a good time to add it.
- Replaced the Vanilla game's erratic swimming AI with a custom, smoother physics simulation that doesn't launch them out of the water every couple of seconds like a dolphin.
- Included 7 new unique water-swishing sound effects as part of the swimming animation.
- Hamsters can now dive underwater in persuit of items they want to steal/snack on.
- They will still do their best to avoid water the rest of the time, but now they don't look so broken when they inevitably fall into it.
- Hide & Seek Mini-Game**
- Tamed hamsters now occasionally get the urge to disappear into the woodwork.
- If they find a suitable hiding spot (bushes, chests, barrels, etc.), they will leap into it and vanish.
- You have a limited time to find them (configurable, ~45-60 seconds by default) before their short attention span gets the better of them. If you try to break or interact with the block they are hiding in during that time, you win! They will pop out and reward you with an item from their cheek pouches.
- If the timer runs out before you find them, they will emerge, sulk, and you get nothing.
- The block they are hiding in will occasionally jiggle, make noise, and spawn particles to help you locate them.
- You will also see a trail of subtle particles from your location directly towards the hiding spot, provided you are within 25 blocks of the hidden hamster.
- These effects will be *very* scarce at the start, but dynamically increases in frequency/intensity as the game progresses.
- Configurability:** Everything is customizable in the config. You can adjust the initiation chance, duration, block lists, and whether they are allowed to hide inside storage blocks like chests.
- Storage Crates**
- Thanks to [**@The Retro Stitcher**](https://theretrostitcher.com/) for helping to design new compacting storage crates for Acorns, Cucumbers, Green Beans, and Hamster Food Mix.
- Fully compatible with LabPBR shader materials out-of-the-box.
- "Hamtaro" Easter Egg**
- Renaming a hamster "Hamtaro" gives it a special texture. This functions identically to the "Sweet Potato" easter egg. Both base textures provided by [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com)!
- New "Panda" Overlay Pattern**
- Added a new "Panda" fur overlay pattern to the genetics engine, allowing you to breed panda-like hamsters. To get a "Panda" hamster, you'll need a Black base coat and a white overlay with the new "Panda" pattern. These can't be found in the wild, since black hamsters do not spawn with white overlays in the wild (breaks their camouflage). Thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for the Panda inspiration!
- 3 New Music Discs & Hamster Dancing**
- A legendary new **Cheese Music Disc** featuring the Adorable Hamster Pets theme song, created by yours truly. Can only be obtained by orchestrating a high-velocity, terminal collision between an airborne hamster and a Charged Creeper.
- Alternate Versions**
- The **Parmesan Music Disc:** Features an Orchestral remix of the Adorable Hamster Pets theme song. Piglins are apparently lactose aficionados. Trade a regular Cheese Music Disc with a Piglin to receive this highly adventurous, grated alternative.
- The **Blue Cheese Music Disc:** Features a Low-Fi remix of the Adorable Hamster Pets theme song. Obtainable by tossing a regular Cheese Music Disc into the End exit portal after defeating the dragon. The void will age the cheese and violently spit it back out at you.
- ⚠️ **Content Creators ↓**
- All three songs are **fully licensed** and safe for YouTube & Twitch monetization. Feel free to feature them in your videos!
- If playing in a Jukebox, nearby hamsters will dance to the music.
- Tried one of the remixes but not a fan? Surround the Blue Cheese or Parmesan discs with regular Cheese in a crafting table to restore them to their original 8-Bit glory.
- Added new advancements and guidebook pages hinting about how to obtain them.
- Modded Music Disc Support**
- Added a
Dancing Music Discsstring list in the config that contains a few strings by default:hamster,hampter, andhamtaro. If a jukebox plays a music disc containing any of these configured strings in its name, description, or lore (case-insensitive), nearby hamsters will dance to it. - Inter-Hamster Tag Mini-Game**
- Hamsters will now spontaneously instigate games of tag with each other.
- The instigator will sprint up to an unsuspecting victim, deliver a visual (damage-free) slap (using a new cowbell sound effect), and sprint away to begin the chase.
- If the chaser catches the instigator or if the 15-second timer runs out, the game ends and both hamsters celebrate.
- Tethering:** The instigator dynamically restricts its flee path to stay within 14 blocks of you (if tamed), ensuring they don't sprint off a cliff or into an unloaded chunk during the heat of the chase.
- Player Interruption:** Right-clicking either hamster while they are playing tag with each other will instantly break up the game and send them back to their normal routines, but will not reward you with a gift.
- Population-Independent Rarity:** The probability math dynamically adjusts based on the local hamster population. Whether you have 2 hamsters in your base or an apocalyptic horde, you will only see an average of 1 game per minute in that area.
- Configurability:** Added
Enable Hamster-vs-Hamster Tag,Average Minutes Between Games, andInter-Hamster Tag Durationsettings to the config. - New Ambient Sitting Animation**
- Added a new "sitting roll" animation where sitting hamsters occasionally roll on their backs. Comes with new sound effects, and it's configurable in the new "Ambient Sitting Behaviors" config group, which also controls cleaning frequency.
- Includes a "Cartoon Rolling Sound" config toggle. By default, the hamster's rolling SFX will include a cartoon-ish slide whistle. It's subtle, but some people might get distracted easily or prefer more realism.
- Hamster Armor Template Duplication**
- Hamster Smithing Templates can now be duplicated on a crafting table!
- Use 1 Template (top center), 1 corresponding material ingot/gem (center), and 7 Acorn Shards.
- Botanical Vandalism (Sapling Trimming)**
- You can now right-click any sapling with a pair of Shears to instantly turn it into a Dead Bush. This provides a much more accessible way to gather the necessary materials for crafting Hamster Bedding if you don't live near a desert.
- Added a new page to the *Hamster Tips* guidebook detailing this mechanic.
- Free Bed Respawn Toggle**
- Added a config toggle to allow hamsters to respawn at their linked beds indefinitely without requiring a tribute item charge (like a Totem of Undying). Disabled by default.
- Dynamic Trees Compatibility**
- Added out-of-the-box support for [**Dynamic Trees**](https://modrinth.com/mod/dynamictrees) via some new config settings.
- Replaced hardcoded oak leaves checks with a new
Heistable Leaveslist in the config, allowing modpack makers to easily add other modded leaves or trees to the heist feature. - Added a new
Heistable Logslist to theTree Heist Settingsconfig, similar to theHeistable Leaveslist. This means you can now start a tree heist by throwing the hamster at a branch or the trunk. - Developed a dumber but more compatible canopy-mapping algorithm that activates automatically if
Dynamic Treesis installed, ensuring heist still works without the vanilla leaves' internaldistance from trunkproperty. - Acorn Note:** The Dynamic Trees mod adds their own type of acorns and drop methods. When that mod is installed, the only way to get the specific acorns from my mod is through the Tree Heist.
- Dehydration and NutritionZ Compatibility**
- Added built-in datapacks for the [**Dehydration**](https://modrinth.com/mod/dehydration) and [**NutritionZ**](https://modrinth.com/mod/nutritionz) mods. Cucumbers will now hydrate you, and Cheese will finally clog your arteries properly.
- Combustible Acorns**
- Acorns can now be used as furnace fuel, smelting exactly the same amount of items as a vanilla stick.
- Alternatively, placing an Acorn in the top slot of a furnace will smelt it down into a piece of Charcoal.
- World Gen Compatibility Enhancements**
- Added massive out-of-the-box biome compatibility configuration data for [**Oh The Biomes We've Gone**](https://modrinth.com/mod/oh-the-biomes-weve-gone), ensuring hamster variants properly disperse across their beautiful landscapes. Huge thanks to [**@jlk2003r**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for helping configure these lists!
- Create Mod Compatibility**
- Added out-of-the-box recipe compatibility for [**Create: Bitterballen**](https://modrinth.com/mod/create-bitterballen) and [**Create Crafts & Additions**](https://modrinth.com/mod/createaddition).
- You can now mill, crush, compact, roast, and smoke AHP Sunflower Seeds to progress through the Bitterballen tech tree seamlessly, bypassing the need to hunt down vanilla sunflowers. Thanks to [**@jlk2003r**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for teaching me about Create so I knew what recipes to add!
- Armor Tier Jumping**
- You can now upgrade Hamster Armor between any tiers using the Smithing Table (e.g., Iron to Diamond, Diamond to Netherite). Previously, all upgrades had to start from base Acorn Armor. You can also downgrade it... should you decide to do so.
- Infinite Bed Respawns**
- Added a new
Tribute One-Time Useconfig setting. When enabled, a bed only requires the tribute item (Totem of Undying by default) once, permanently unlocking infinite respawns for that specific bed and hamster. - Taming Feedback**
- The mod will now provide snarky chat feedback if you try to tame a hamster incorrectly (such as not sneaking or offering them the wrong food) and will point you to the guidebook for help.
- Hamster Bed Placement Safeguard**
- Unlinked hamster beds can no longer be placed in the world accidentally.
- Attempting to do so for the first time triggers an audible warning and chat message explaining that they must be linked to a hamster first.
- After receiving the warning, a 2-second cooldown begins. Once it expires, players are allowed to place the unlinked bed freely. The game remembers that you've been warned and won't bother you again.
- Added config settings under 'Hamster Beds & Wander Mode' to disable the warning entirely, or to clear your history so you can experience it all over again.
- The tooltips and guidebook entries have been updated to make the linking process ("right-click a hamster with bed in hand") much clearer.
- Global Notification Toggle**
- Added a
Server Disable Announcementsconfig setting. Server owners can now globally disable the notification bell icon for all connected players. - Smoker Support**
- Green Beans can now be cooked into Steamed Green Beans using a Smoker, which cooks them twice as fast as a standard furnace.
- Compostable Sunflowers**
- The custom Adorable Hamster Pets Sunflower can now be placed in a composter (matching the 65% compost chance of vanilla sunflowers).
- Plantable Acorns**
- Acorns can now be planted directly on dirt/grass to grow vanilla Oak Trees. Once placed they will become Oak Saplings.
### Changed
- Config GUI Major Overhaul**
- During development on v3.6.1, the mod's configuration file exceeded Minecraft's hard-coded networking limits due to a Fzzy Config NeoForge bug which I've already reported. As a work-around, the main config has been split into multiple smaller, organized configs. It needed to be done anyway, so I simultaneously re-organized everything, making it more intuitive to navigate.
- Dismount Keybinding Simplification**
- Removed the confusing config toggle that forced players to enable a custom keybind in the config before they could rebind the "Dismount Hamster" key in the
Controls > Key Bindsmenu. The keybind is now permanently exposed. - The "Dismount Hamster" keybind now utilizes an unbound fallback system. By default, the keybind is set to
Unbound, and the game will naturally listen to your vanillaSneakkey to dismount hamsters. However, if you manually assign a key to it in the controls menu, it will override the sneak behavior and listen exclusively to your custom key. - The default "Button-Press Behavior" config setting has been changed from
Single PresstoDouble Tapto prevent accidental dismounts when sneaking near ledges. Originally it was set to single press to mimic vanilla parrot behavior, but it's just so annoying. I finally can't stand it anymore. Lol. - Added a
Custom Key Behavior Overrideconfig toggle (true by default). When you bind a custom key for dismounting, it automatically overrides theDouble Tapbehavior and makes it aSingle Press. I assume if you assigned a dedicated key to it, you don't want to have to tap it twice. - Keybind Names**
- Renamed several of the key binds to make the
Controls > Key Bindsmenu more intuitive. - Hamster Attacking AI**
- Hamsters can no longer pathfind outside the follow radius when targeting entities. They will instead exhibit erratic behavior near the edge of the boundary.
- This prevents repetitive teleportation back to the player when the hamster is aggressively targeting something outside the follow distance.
- To compensate, follow distance has been increased by five blocks when the hamster is in MENACE mode.
- The Hamster Yeet**
- Throwing a hamster is no longer canceled/prevented if the player's crosshair is over non-solid blocks like tall grass, flowers, sugar cane etc.
- Reduced the default gravity applied to thrown hamsters by 30%, resulting in naturally longer, flatter arcs out-of-the-box. Hamsters will feel less "heavy" now during throws.
- Thrown hamsters now generate a shower of block-breaking particles upon impacting a surface.
- Resolved an issue where players throwing their hamsters very far away wouldn't hear some of the animation-based impact sounds due to vanilla audio distance attenuation.
- Hamster Tips Guidebook**
- "The Great Escape" has been renamed to "Beds & Wander Mode," and "Acorn Armor" has been renamed to "Tree Heist & Armor" so you guys won't keep coming into my Discord server asking how the beds work and where to find acorns 😂
- This has another super useful perk: Now whenever you search through the guidebook for a specific topic, you can search for things like "bed," "tree heist," or "armor" and those specific entries will pop up in the results.
- Now utilizes dynamic text injection to accurately display your configured resurrection tribute items. So now if a server owner or modpack creator changes the default item from a Totem of Undying, the guidebook will update itself automatically.
- Tag Mini-Game**
- Wild hamsters can no longer initiate a game of tag to prevent interference with taming. Tamed hamsters can still play tag with strangers if enabled in the config.
- The game will no longer randomly start while you are sneaking, preventing interference with petting.
- You can now manually start a game of tag on-demand by rapidly sneaking and un-sneaking while maintaining eye contact with a tamed hamster.
- Since there is now a manual trigger, the chance of the game starting is now much lower. You will need to stare at a hamster for ~15 seconds on average for the game to automatically start.
- Starting a game of tag now plays a sound, spawns particles, and displays an action bar message to clearly indicate that it is a fun event and not a bug.
- Hamsters will now lovingly slap you (applying knockback and brief nausea, but no damage) when the game starts.
- Added a 1-second interaction cooldown when the game starts to prevent accidentally catching the hamster immediately.
- Genetics & Color Groups**
- Renamed the
ROSEcolor group toCHERRYsince the only hamster in that group is the "Pearl Rose" hamster, which is basically pink anyway. - Added a new
RUSTcolor group. The "Rust" hamster has officially been evicted from theORANGEcategory, allowing it to have its own dedicated spawning rules. - Spawning Config Overhaul**
- Reorganized the World Gen config UI to clearly separate the global "Allow/Prevent Spawns" lists from the "Region-Based Color Filters". It now clearly explains the "filter funnel" concept so you know exactly why the Plains environment acts as a catch-all.
- Expanded the procedural spawning logic from 10 environments to 12, giving modpack makers perfect 1:1 granular control over all 12 hamster color groups.
- The Wildcard:** Added a "Priority 1: Wildcard" zone. Allows server owners to surgically extract specific biomes from broader categories and assign them unique colors without overhauling the other lists. (i.e., If you wanted to separate the environments in which Light Gray and Dark Gray hamsters spawn, now you can do so).
- Sky Environments:** Added a dedicated zone for floating island biomes to host the
SKYcolor group. Vanilla players— no need to freak out; there's still a 15% chance to findSKYhamsters instead ofWHITEin snowy areas. - Cherry Environments:** Extracted Cherry Groves out of the Magical environments so they can be balanced independently. Defaults to 100%
CHERRYhamsters. - Auburn Environments:** Added a dedicated zone targeting Badlands (and modded autumnal forests with red trees if you like). This is the exclusive new home for
RUSThamsters. (ORANGEhamsters will no longer spawn in Badlands by default). - Re-balanced Weights:** Adjusted the default spawning weights across the
Icy,Magical, andSnowyenvironments to accommodate the new color zones. - ⚠ Important Config Note for Existing Worlds**
- If you are updating an existing modpack, your old config files will obstinately hold on to their old settings. This is good, otherwise you would lose all your work every time I pushed out an update. However, this means that in order to see these new default spawn weights, you will need to right-click specific settings in the config screen and select "Restore Defaults." Alternatively, click the "Changes" button (bottom-right corner) and click "Restore Defaults" to reset everything at once (only affects the config from my mod).
- Hamster Bedding Leaf Particles**
- Doubled the visual size of the Hamster Bedding particles to better match the leaves on the trees and on the hamster bed itself.
- Pink Petal Accessories**
- Added a new config toggle (true by default) to dynamically render Pink Petal accessories on the outside of equipped armor, so your hamster can be safe and fabulous simultaneously.
- Configurable 3D Visualizer Particles**
- Added a
Continuous Genetics Cylindertoggle to the config. When disabled, the 3D bounding cylinder generated by/ahp spawn_all_bases_3Dwill only render for the first second after spawning to reduce clutter. - Spawning & Testing Commands**
- Added
/ahp undo_last_spawn. Easily discards all hamsters spawned by your very last/ahp spawn...command. Perfect for when you set up a hamster display and then accidentally run the 2-million permutation command in the wrong location. - Overhauled the
/ahp spawn_all_possible_permutations_THIS_CAN_BREAK_YOUR_WORLDcommand. It is now called/ahp spawn_random_group <count>. - You must now provide a
<count>argument. It accepts standard numbers (e.g., 500) or anall_THIS_CAN_BREAK_YOUR_WORLDstring. - Hamsters are now spawned in a completely randomized order and placement on the grid.
- If the requested count is 5,000 or less, the hamsters are spawned synchronously and instantly without invoking the asynchronous batch-spawning system.
- Added five additional optional arguments to the 2D, 3D, and randomized spawn commands:
[spacing_multiplier],[match_player_yaw],[randomize_sitting],[randomize_sleeping], and[randomize_yaw]. These arguments allow you to expand or shrink the physical distance between the spawned hamsters, force the entire grid of spawned hamsters to face one direction, a random direction, and/or give them static poses to keep things more visually interesting. - Added a new argument to the
/ahp spawn_random_groupcommand calleduse_wild_overlay_rules_for_breeding_overlays. Allows you to spawn a more realistic/natural looking random group of hamsters. - Added a new
<pose>argument to the/ahp spawn hamstercommand, allowing you to specify sitting, sleeping, idle, or none. - Added personality ID's for command-spawned hamsters. The random sitting/sleeping poses are based on that ID, so they will retain those poses even after being tamed.
- Updated the
Admin Commandschapter in the *Hamster Tips* guidebook to include descriptions for these new commands and arguments. - Hamster Bed Placement**
- Placing down a new hamster bed no longer forces the hamster to sleep in it immediately unless the conditions are correct (i.e., time of day, config settings).
- Wandering Hamster Sitting**
- Hamsters linked to a bed will no longer automatically sit down when their owner logs out or changes dimensions, as long as the bed is still intact.
### Fixed
- Hamsters Falling Into End Portals**
- Hamsters that wander into the exit End Portal will now bounce right back out, complete with particle and sound effects.
- Prevents them from teleporting to the Overworld spawn coordinates and getting lost.
- Added a toggle to the config to revert to standard vanilla behavior if desired.
- Hamster Yeet & Evilcraft Bug**
- Resolved an bug that prevented hamsters from being thrown on Forge and NeoForge dedicated servers, caused by environment annotations running on the server thread. Super niche little insect that slipped by because it doesn't exist on Fabric. You should be able to throw your hamsters in multiplayer again!
- This also resolves a server startup crash when playing with EvilCraft, which attempts to instantiate the projectile to check its blood levels. Lol.
- Food Item Stacking**
- Resolved an issue on 1.21.1 where the configurable food items became unstackable in the inventory GUI after being split or spread.
- Implemented a stable ComponentMap caching system to ensure GUI right-click dragging correctly identifies dynamic food stacks as equal.
- Sliced Cucumber Feeding**
- Resolved a bug where already-tamed hamsters would refuse to eat their taming food (e.g. Sliced Cucumber) to heal or breed.
- Projectile Accessories**
- Fixed a visual bug where a hamster's equipped armor and accessories would temporarily vanish while they were airborne during a throw.
- Server Performance**
- Resolved a few pathfinding and AI issues where tamed hamsters following the player would sometimes experience server-tick lag spikes. Usually you wouldn't notice these unless you had a lot of hamsters following you at once.
- Wander Mode Override**
- Resolved a bug where disabling Wander Mode in the global config wouldn't stop already-wandering hamsters from lingering around their beds.
- Cheese Item Texture**
- Finally fixed the 99% transparent pixel in the bottom left corner of the cheese item texture. I only recently realized what was causing it to look so strange. Lol
- Console Log Spam**
- Resolved an issue where players with internet disabled (or those playing in regions where GitHub is blocked) would receive a massive, screen-filling error stack trace in their console every 5 minutes when the mod silently checked for updates in the background. Background network failures are now politely logged as a single warning line.
- Resolved an issue where the genetics engine would spam the server console with warnings when attempting to generate wild overlays for hamsters with extremely bright base coats (like Coconut).
- Sweet Potato Easter Egg**
- Renaming a hamster to "Sweet Potato" now correctly applies the easter egg texture without accidentally deleting the hamster's eyes, skin layer, and accessories. So that's good.
- Resolved an issue where the effects would trigger immediately upon renaming a hamster via the GUI, before the screen was closed.
- Resolved an issue where the affects would not trigger at all on 1.20.1 if a hamster was renamed via the GUI.
- Missing Vanilla Tags**
- The custom AHP Sunflower block is now properly registered under the vanilla
#minecraft:flowersand#minecraft:tall_flowerstags. This resolves compatibility issues with mods like Alex's Mobs that rely on these tags to identify flowers in the world. - Flashback Mod**
- Resolved a server crash that occurred when scrubbing through replay timelines using the Flashback mod, caused by missing NBT data on Hamster Beds.
- Resolved a persistent desync issue where shoulder hamsters would disappear when scrubbing backwards or jumping to different points on the replay timeline. Future replays will hopefully be fixed via a periodic server-side data sync that runs once per second.
- File Parsing Crashes**
- Fixed a crash that occurred when reading corrupted
.jsoncache files for the supporter perk system. It will now safely ignore the corrupted file and download a fresh copy from the internet. - Guidebook Server Synchronization**
- Resolved an issue where the "Missing Guidebook" chat warning would trigger repeatedly across multiple game sessions when playing on a dedicated server due to a configuration synchronization flaw.
- Fixed an issue where players were falsely led to believe they could locally disable Guidebook Auto-Delivery on dedicated servers. These settings now properly sync from the server to the client's config UI, reflecting the server's true authority over the book's delivery.
- Food Interactions**
- Fixed a bug where players could not toggle their hamster's sitting state if they were holding Hamster Food Mix or other food items.
- "Hampter"** Custom Name
- The "Use 'Hampter' as Default Name" config setting now properly reflects on the Jade HUD overlay and the Hamster Inventory screen.
- Cheek Pouch Allowed Items**
- Fixed an issue where all vanilla food items were forbidden in the Cheek Pouch on 1.20.1 due to a typo.
- Spawn Commands**
- Resolved an issue where AI-disabled hamsters generated by
/ahp spawn_all_bases_3Dwould sometimes suffocate and die if they spawned inside each other. They are now completely invulnerable until they are tamed/woken up. - Cheek Pouch Desync**
- Fixed an issue where a hamster's cheek pouches would visually deflate in heavily modded environments due to partial NBT syncing from mods like Jade.
- Guidebook Recovery Routing**
- The "Missing Guidebook" chat warning now correctly opens the root configuration menu so the recovery button is actually visible.

# **The Punchy Patch**
In addition to a bunch of new mini-games, idle animations and QoL features (including hamster armor trims & toggleable aggression states!), this patch introduces 5 new super cute, first-person animations to your rodent-handling experience, courtesy of the amazing **Punchy mod!** I've been working closely with [**@Dev Punchy Man**](https://modrinth.com/mod/punchy-fpa) to overhaul how it feels to pick up, pet, yeet, and dismount your hamsters.
### 👉🏼 [**Showcase video**](https://www.youtube.com/watch?v=YGRdjOTCMHo) 👈🏼
### Added
- New First-Person Animations** _(Optional: Requires Punchy v2.6.0+)_
- Note: The Punchy mod is **not a required dependency** for Adorable Hamster Pets. It is only required if you want to experience these specific new first-person animations listed below:
- Petting/Tickling Animation** _(Requires Punchy v2.6.0+)_
- You can finally pet your hamster! If you stare affectionately at your hamster for a **while sneaking** (about 15 seconds on average), you might just reach down, pick it up and give it some tickles. Comes with a new animation where the hamster flips over on your hand and asks for a belly rub! Also added a dedicated "Pet Hamster" keybind (unbound by default) for when you don't feel like waiting for the random chance to kick in.
- For those with the patience of a fruit bat, pressing your "Pet Hamster" key or clicking your mouse will cancel the petting animation. You don't need to be sneaking to use the keybind.
- If the hamster was sitting before you picked it up to pet it, it will remain seated when you place it back down, making this a great way to manually re-position tamed hamsters around your base.
- Shoulder Mounting Animations** _(Requires Punchy v2.6.0+)_
- Luring a hamster to your shoulder is no longer a boring teleport. You will now physically lift them up, complete with the hamster adorably bouncing on your hands or running up your arm. Three new unique animations; dynamically changing depending on their destination (left shoulder, right shoulder, head).
- Hamster Yeet Animations** _(Requires Punchy v2.6.0+)_
- Holding down the throw key (
G) grabs a specific hamster off your shoulder and holds it in front of your face. _(For more info, see "Hamster Yeet Mechanics" below)._ - While queued up, the hamster also plays its own new animation _(Requires Punchy v2.6.0+)_ where it eagerly wiggles its butt and kicks its back feet in anticipation of being hurled through the air.
- Releasing the throw key (
G) executes the throw, which is immediately followed by a new Punchy animation where you wave goodbye to your furry projectile. - If you release the key before the short charging period (
15 ticks) is over, you safely abort the throw. Your character will politely place the hamster back onto the exact shoulder it came from. - Hamster Yeet Mechanics**
- The Yeet Queuing System**
- Throwing a hamster is no longer instant. You must hold down the throw key (
Gby default) to "queue" a hamster for throwing. Includes new animations if the Punchy mod is installed. _(for more info, see "New First-Person Animations" above)_. - Releasing the throw key (
G) executes the throw. - If you release the key before the short charging period (
15 ticks) is over, you safely abort the throw. This charging period of15 ticksis not configurable, due to its duration needing to match the Punchy mod's animation. But it's quite short— only0.75 seconds— so hopefully it won't impact gameplay. - Hamsters Weigh Less**
- Added a
Downward Force (Gravity)slider to the config, allowing you to fine-tune how far hamsters fly without needing to increase their initial thrust. - Reduced the default gravitational force by ~30%, so hamsters will fly a little bit further now. (Useful for recording hamster flights with the Flashback mod, which gets buggy when entities are moving very quickly through the air).
- FOV Zoom**
- Added a smooth FOV zoom effect while queueing the Hamster Yeet, identical to drawing a vanilla bow. This FOV zoom will help indicate the new charging period for anyone who doesn't have Punchy installed, since the new animations are part of Punchy.
- Cooldown Recovery**
- If you're impatient, feeding your hamster will now incrementally reduce its throw cooldown (similar to how feeding accelerates baby growth).
- More Feedback**
- A new action bar message will let you know when the hamster has recovered from its concussion and is ready for launch.
- More Flower Accessories**
- Expanded the old "Pink Petal" accessory. You can now equip **any flower in the
#flowerstag** onto your hamster instead of just Pink Petals. - There are 12 unique textures. The texture assignment logic automatically scans the registry names of flowers. It uses an extensive list of color keywords and botanical families to ensure almost any flower you apply (even modded flowers) will have the correct color palette.
- The color assignment logic is completely data-driven. You can easily force a modded flower to use a specific color palette using standard Minecraft Item Tags (e.g., adding an item to
#adorablehamsterpets:flower_accessories/overlay_wither_rose). - For a tutorial, pop over to [**The Cheek Pouch**](https://discord.gg/w54mk5bqdf) Discord server, visit the **FAQ channel**, and search for _Custom Flower Accessories._
- Added new pages to the *Hamster Tips* guidebook explaining how the dynamic color assignment and tag overrides work.
- Shader LabPBR Material Support**
- All items, blocks, particles, and entities in this mod now include their own LabPBR-compliant Specular and Normal textures (with hamsters generating theirs procedurally), giving them detailed, per-layer PBR effects (emission, subsurface scattering, specular reflections, porosity, etc.) out-of-the-box with supported shaders.
- Must have your shader's material settings set to "LabPBR" or "Hardcoded + LabPBR"
- Metal armors have a "Vanilla-inspired" glossiness by default, but if you prefer hardcore realism and want them super metallic/reflective, I added custom sliders in the config allowing you to manually fine-tune the PBR values for each individual armor type.
- Added a
Max POM Depthslider to allow fine-tuning of the procedural 3D fur displacement (only works if your shader supports POM on entities, which is extremely rare). - Armor Trims**
- Hamster Armor can now be customized with vanilla armor trims in the Smithing Table.
- The following trims are currently available: Coast, Border, Vex, Eye, Sentry, Wild
- They will naturally glow in the dark and automatically have emission with shader mods like Iris.
- Added an
Emissive Armor Trimstoggle in the client config so you can disable the glowing effect if you hate fun and prefer a non-luminescent reality. - Added a
Trim Emissive Brightnessslider to give you precision control over exactly how blinding the neon lines should be. - Configurable Aggression States**
- Hamsters now have three distinct aggression states controlled by their diet.
- Pacifist:** Sneak + right-click them any vanilla flower (e.g.,
#minecraft:flowers). They become total hippies and will refuse to attack anything, even if you are being actively mauled. - Standard:** Sneak + right-click them Sunflower Seeds to factory-reset them back to their normal, wolf-like defensive behavior.
- Menace:** Sneak + right-click them a Spider Eye to unleash their inner demon. They will actively hunt down anything on the configurable "Menace Targets" list (which defaults to all monsters and bosses), and gain an expanded follow radius to give them more room to fight. If a target is outside their follow radius, they will move frantically at the edge of the tether.
- All trigger items are fully configurable, and changing a hamster's state produces a visual and audio confirmation.
- If you have jade installed, its overlay will display the hamster's current Aggression State when it is set to something other than the default, and can be toggled in the config alongside the other genetic displays.
- Hamster Tips Guidebook Entry**
- The *Hamster Tips* guidebook now features a dedicated "Aggression States" page to explain the new mechanics. It utilizes dynamic text injection to accurately display your configured trigger items, ensuring the book is always up-to-date even if a modpack creator changes the required diets.
- Pacifist Break:** Added a
Pacifist Break on Attackconfig toggle (false by default). When enabled, a passive hamster will automatically revert to neutral if it sees you attacking something. - Crop Harvesting**
- Tamed, wandering hamsters now possess an irrepressible desire for the occasional midnight snack.
- If they find a fully mature crop nearby and they have room in their cheek pouch, they will violently pounce on it, aggressively stuff the harvest into their cheek pouches, and accidentally replant some seeds in the process.
- Includes dynamic block particles and a leaf-crunching sound effect when pouncing on the crop block.
- Includes dynamic item particles when the hamster scoops up the dropped seeds and harvest items.
- Added a new
Crop Snacking Settingsallowing you to disable the feature entirely, tweak the cooldown, or add specific crops from their menu. - Added a new custom
#adorablehamsterpets:crop_itemsunion tag so hamsters can recognize and eat/harvest most modded crops and vegetables out of the box. - Added two new "Crop Harvesting" pages to the *Hamster Tips* guidebook explaining the feature.
- Swimming Mechanics**
- Added a new swimming animation loop for hamsters that accidentally fall into the water. This seems to happen a lot when they are snacking on crops so I thought it was a good time to add it.
- Replaced the Vanilla game's erratic swimming AI with a custom, smoother physics simulation that doesn't launch them out of the water every couple of seconds like a dolphin.
- Included 7 new unique water-swishing sound effects as part of the swimming animation.
- Hamsters can now dive underwater in persuit of items they want to steal/snack on.
- They will still do their best to avoid water the rest of the time, but now they don't look so broken when they inevitably fall into it.
- Hide & Seek Mini-Game**
- Tamed hamsters now occasionally get the urge to disappear into the woodwork.
- If they find a suitable hiding spot (bushes, chests, barrels, etc.), they will leap into it and vanish.
- You have a limited time to find them (configurable, ~45-60 seconds by default) before their short attention span gets the better of them. If you try to break or interact with the block they are hiding in during that time, you win! They will pop out and reward you with an item from their cheek pouches.
- If the timer runs out before you find them, they will emerge, sulk, and you get nothing.
- The block they are hiding in will occasionally jiggle, make noise, and spawn particles to help you locate them.
- You will also see a trail of subtle particles from your location directly towards the hiding spot, provided you are within 25 blocks of the hidden hamster.
- These effects will be *very* scarce at the start, but dynamically increases in frequency/intensity as the game progresses.
- Configurability:** Everything is customizable in the config. You can adjust the initiation chance, duration, block lists, and whether they are allowed to hide inside storage blocks like chests.
- Storage Crates**
- Thanks to [**@The Retro Stitcher**](https://theretrostitcher.com/) for helping to design new compacting storage crates for Acorns, Cucumbers, Green Beans, and Hamster Food Mix.
- Fully compatible with LabPBR shader materials out-of-the-box.
- "Hamtaro" Easter Egg**
- Renaming a hamster "Hamtaro" gives it a special texture. This functions identically to the "Sweet Potato" easter egg. Both base textures provided by [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com)!
- New "Panda" Overlay Pattern**
- Added a new "Panda" fur overlay pattern to the genetics engine, allowing you to breed panda-like hamsters. To get a "Panda" hamster, you'll need a Black base coat and a white overlay with the new "Panda" pattern. These can't be found in the wild, since black hamsters do not spawn with white overlays in the wild (breaks their camouflage). Thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for the Panda inspiration!
- 3 New Music Discs & Hamster Dancing**
- A legendary new **Cheese Music Disc** featuring the Adorable Hamster Pets theme song, created by yours truly. Can only be obtained by orchestrating a high-velocity, terminal collision between an airborne hamster and a Charged Creeper.
- Alternate Versions**
- The **Parmesan Music Disc:** Features an Orchestral remix of the Adorable Hamster Pets theme song. Piglins are apparently lactose aficionados. Trade a regular Cheese Music Disc with a Piglin to receive this highly adventurous, grated alternative.
- The **Blue Cheese Music Disc:** Features a Low-Fi remix of the Adorable Hamster Pets theme song. Obtainable by tossing a regular Cheese Music Disc into the End exit portal after defeating the dragon. The void will age the cheese and violently spit it back out at you.
- ⚠️ **Content Creators ↓**
- All three songs are **fully licensed** and safe for YouTube & Twitch monetization. Feel free to feature them in your videos!
- If playing in a Jukebox, nearby hamsters will dance to the music.
- Tried one of the remixes but not a fan? Surround the Blue Cheese or Parmesan discs with regular Cheese in a crafting table to restore them to their original 8-Bit glory.
- Added new advancements and guidebook pages hinting about how to obtain them.
- Modded Music Disc Support**
- Added a
Dancing Music Discsstring list in the config that contains a few strings by default:hamster,hampter, andhamtaro. If a jukebox plays a music disc containing any of these configured strings in its name, description, or lore (case-insensitive), nearby hamsters will dance to it. - Inter-Hamster Tag Mini-Game**
- Hamsters will now spontaneously instigate games of tag with each other.
- The instigator will sprint up to an unsuspecting victim, deliver a visual (damage-free) slap (using a new cowbell sound effect), and sprint away to begin the chase.
- If the chaser catches the instigator or if the 15-second timer runs out, the game ends and both hamsters celebrate.
- Tethering:** The instigator dynamically restricts its flee path to stay within 14 blocks of you (if tamed), ensuring they don't sprint off a cliff or into an unloaded chunk during the heat of the chase.
- Player Interruption:** Right-clicking either hamster while they are playing tag with each other will instantly break up the game and send them back to their normal routines, but will not reward you with a gift.
- Population-Independent Rarity:** The probability math dynamically adjusts based on the local hamster population. Whether you have 2 hamsters in your base or an apocalyptic horde, you will only see an average of 1 game per minute in that area.
- Configurability:** Added
Enable Hamster-vs-Hamster Tag,Average Minutes Between Games, andInter-Hamster Tag Durationsettings to the config. - New Ambient Sitting Animation**
- Added a new "sitting roll" animation where sitting hamsters occasionally roll on their backs. Comes with new sound effects, and it's configurable in the new "Ambient Sitting Behaviors" config group, which also controls cleaning frequency.
- Includes a "Cartoon Rolling Sound" config toggle. By default, the hamster's rolling SFX will include a cartoon-ish slide whistle. It's subtle, but some people might get distracted easily or prefer more realism.
- Hamster Armor Template Duplication**
- Hamster Smithing Templates can now be duplicated on a crafting table!
- Use 1 Template (top center), 1 corresponding material ingot/gem (center), and 7 Acorn Shards.
- Botanical Vandalism (Sapling Trimming)**
- You can now right-click any sapling with a pair of Shears to instantly turn it into a Dead Bush. This provides a much more accessible way to gather the necessary materials for crafting Hamster Bedding if you don't live near a desert.
- Added a new page to the *Hamster Tips* guidebook detailing this mechanic.
- Free Bed Respawn Toggle**
- Added a config toggle to allow hamsters to respawn at their linked beds indefinitely without requiring a tribute item charge (like a Totem of Undying). Disabled by default.
- Dynamic Trees Compatibility**
- Added out-of-the-box support for [**Dynamic Trees**](https://modrinth.com/mod/dynamictrees) via some new config settings.
- Replaced hardcoded oak leaves checks with a new
Heistable Leaveslist in the config, allowing modpack makers to easily add other modded leaves or trees to the heist feature. - Added a new
Heistable Logslist to theTree Heist Settingsconfig, similar to theHeistable Leaveslist. This means you can now start a tree heist by throwing the hamster at a branch or the trunk. - Developed a dumber but more compatible canopy-mapping algorithm that activates automatically if
Dynamic Treesis installed, ensuring heist still works without the vanilla leaves' internaldistance from trunkproperty. - Acorn Note:** The Dynamic Trees mod adds their own type of acorns and drop methods. When that mod is installed, the only way to get the specific acorns from my mod is through the Tree Heist.
- Dehydration and NutritionZ Compatibility**
- Added built-in datapacks for the [**Dehydration**](https://modrinth.com/mod/dehydration) and [**NutritionZ**](https://modrinth.com/mod/nutritionz) mods. Cucumbers will now hydrate you, and Cheese will finally clog your arteries properly.
- Combustible Acorns**
- Acorns can now be used as furnace fuel, smelting exactly the same amount of items as a vanilla stick.
- Alternatively, placing an Acorn in the top slot of a furnace will smelt it down into a piece of Charcoal.
- World Gen Compatibility Enhancements**
- Added massive out-of-the-box biome compatibility configuration data for [**Oh The Biomes We've Gone**](https://modrinth.com/mod/oh-the-biomes-weve-gone), ensuring hamster variants properly disperse across their beautiful landscapes. Huge thanks to [**@jlk2003r**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for helping configure these lists!
- Create Mod Compatibility**
- Added out-of-the-box recipe compatibility for [**Create: Bitterballen**](https://modrinth.com/mod/create-bitterballen) and [**Create Crafts & Additions**](https://modrinth.com/mod/createaddition).
- You can now mill, crush, compact, roast, and smoke AHP Sunflower Seeds to progress through the Bitterballen tech tree seamlessly, bypassing the need to hunt down vanilla sunflowers. Thanks to [**@jlk2003r**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for teaching me about Create so I knew what recipes to add!
- Armor Tier Jumping**
- You can now upgrade Hamster Armor between any tiers using the Smithing Table (e.g., Iron to Diamond, Diamond to Netherite). Previously, all upgrades had to start from base Acorn Armor. You can also downgrade it... should you decide to do so.
- Infinite Bed Respawns**
- Added a new
Tribute One-Time Useconfig setting. When enabled, a bed only requires the tribute item (Totem of Undying by default) once, permanently unlocking infinite respawns for that specific bed and hamster. - Taming Feedback**
- The mod will now provide snarky chat feedback if you try to tame a hamster incorrectly (such as not sneaking or offering them the wrong food) and will point you to the guidebook for help.
- Hamster Bed Placement Safeguard**
- Unlinked hamster beds can no longer be placed in the world accidentally.
- Attempting to do so for the first time triggers an audible warning and chat message explaining that they must be linked to a hamster first.
- After receiving the warning, a 2-second cooldown begins. Once it expires, players are allowed to place the unlinked bed freely. The game remembers that you've been warned and won't bother you again.
- Added config settings under 'Hamster Beds & Wander Mode' to disable the warning entirely, or to clear your history so you can experience it all over again.
- The tooltips and guidebook entries have been updated to make the linking process ("right-click a hamster with bed in hand") much clearer.
- Global Notification Toggle**
- Added a
Server Disable Announcementsconfig setting. Server owners can now globally disable the notification bell icon for all connected players. - Smoker Support**
- Green Beans can now be cooked into Steamed Green Beans using a Smoker, which cooks them twice as fast as a standard furnace.
- Compostable Sunflowers**
- The custom Adorable Hamster Pets Sunflower can now be placed in a composter (matching the 65% compost chance of vanilla sunflowers).
- Plantable Acorns**
- Acorns can now be planted directly on dirt/grass to grow vanilla Oak Trees. Once placed they will become Oak Saplings.
### Changed
- Config GUI Major Overhaul**
- During development on v3.6.1, the mod's configuration file exceeded Minecraft's hard-coded networking limits due to a Fzzy Config NeoForge bug which I've already reported. As a work-around, the main config has been split into multiple smaller, organized configs. It needed to be done anyway, so I simultaneously re-organized everything, making it more intuitive to navigate.
- Dismount Keybinding Simplification**
- Removed the confusing config toggle that forced players to enable a custom keybind in the config before they could rebind the "Dismount Hamster" key in the
Controls > Key Bindsmenu. The keybind is now permanently exposed. - The "Dismount Hamster" keybind now utilizes an unbound fallback system. By default, the keybind is set to
Unbound, and the game will naturally listen to your vanillaSneakkey to dismount hamsters. However, if you manually assign a key to it in the controls menu, it will override the sneak behavior and listen exclusively to your custom key. - The default "Button-Press Behavior" config setting has been changed from
Single PresstoDouble Tapto prevent accidental dismounts when sneaking near ledges. Originally it was set to single press to mimic vanilla parrot behavior, but it's just so annoying. I finally can't stand it anymore. Lol. - Added a
Custom Key Behavior Overrideconfig toggle (true by default). When you bind a custom key for dismounting, it automatically overrides theDouble Tapbehavior and makes it aSingle Press. I assume if you assigned a dedicated key to it, you don't want to have to tap it twice. - Keybind Names**
- Renamed several of the key binds to make the
Controls > Key Bindsmenu more intuitive. - Hamster Attacking AI**
- Hamsters can no longer pathfind outside the follow radius when targeting entities. They will instead exhibit erratic behavior near the edge of the boundary.
- This prevents repetitive teleportation back to the player when the hamster is aggressively targeting something outside the follow distance.
- To compensate, follow distance has been increased by five blocks when the hamster is in MENACE mode.
- The Hamster Yeet**
- Throwing a hamster is no longer canceled/prevented if the player's crosshair is over non-solid blocks like tall grass, flowers, sugar cane etc.
- Reduced the default gravity applied to thrown hamsters by 30%, resulting in naturally longer, flatter arcs out-of-the-box. Hamsters will feel less "heavy" now during throws.
- Thrown hamsters now generate a shower of block-breaking particles upon impacting a surface.
- Resolved an issue where players throwing their hamsters very far away wouldn't hear some of the animation-based impact sounds due to vanilla audio distance attenuation.
- Hamster Tips Guidebook**
- "The Great Escape" has been renamed to "Beds & Wander Mode," and "Acorn Armor" has been renamed to "Tree Heist & Armor" so you guys won't keep coming into my Discord server asking how the beds work and where to find acorns 😂
- This has another super useful perk: Now whenever you search through the guidebook for a specific topic, you can search for things like "bed," "tree heist," or "armor" and those specific entries will pop up in the results.
- Now utilizes dynamic text injection to accurately display your configured resurrection tribute items. So now if a server owner or modpack creator changes the default item from a Totem of Undying, the guidebook will update itself automatically.
- Tag Mini-Game**
- Wild hamsters can no longer initiate a game of tag to prevent interference with taming. Tamed hamsters can still play tag with strangers if enabled in the config.
- The game will no longer randomly start while you are sneaking, preventing interference with petting.
- You can now manually start a game of tag on-demand by rapidly sneaking and un-sneaking while maintaining eye contact with a tamed hamster.
- Since there is now a manual trigger, the chance of the game starting is now much lower. You will need to stare at a hamster for ~15 seconds on average for the game to automatically start.
- Starting a game of tag now plays a sound, spawns particles, and displays an action bar message to clearly indicate that it is a fun event and not a bug.
- Hamsters will now lovingly slap you (applying knockback and brief nausea, but no damage) when the game starts.
- Added a 1-second interaction cooldown when the game starts to prevent accidentally catching the hamster immediately.
- Genetics & Color Groups**
- Renamed the
ROSEcolor group toCHERRYsince the only hamster in that group is the "Pearl Rose" hamster, which is basically pink anyway. - Added a new
RUSTcolor group. The "Rust" hamster has officially been evicted from theORANGEcategory, allowing it to have its own dedicated spawning rules. - Spawning Config Overhaul**
- Reorganized the World Gen config UI to clearly separate the global "Allow/Prevent Spawns" lists from the "Region-Based Color Filters". It now clearly explains the "filter funnel" concept so you know exactly why the Plains environment acts as a catch-all.
- Expanded the procedural spawning logic from 10 environments to 12, giving modpack makers perfect 1:1 granular control over all 12 hamster color groups.
- The Wildcard:** Added a "Priority 1: Wildcard" zone. Allows server owners to surgically extract specific biomes from broader categories and assign them unique colors without overhauling the other lists. (i.e., If you wanted to separate the environments in which Light Gray and Dark Gray hamsters spawn, now you can do so).
- Sky Environments:** Added a dedicated zone for floating island biomes to host the
SKYcolor group. Vanilla players— no need to freak out; there's still a 15% chance to findSKYhamsters instead ofWHITEin snowy areas. - Cherry Environments:** Extracted Cherry Groves out of the Magical environments so they can be balanced independently. Defaults to 100%
CHERRYhamsters. - Auburn Environments:** Added a dedicated zone targeting Badlands (and modded autumnal forests with red trees if you like). This is the exclusive new home for
RUSThamsters. (ORANGEhamsters will no longer spawn in Badlands by default). - Re-balanced Weights:** Adjusted the default spawning weights across the
Icy,Magical, andSnowyenvironments to accommodate the new color zones. - ⚠ Important Config Note for Existing Worlds**
- If you are updating an existing modpack, your old config files will obstinately hold on to their old settings. This is good, otherwise you would lose all your work every time I pushed out an update. However, this means that in order to see these new default spawn weights, you will need to right-click specific settings in the config screen and select "Restore Defaults." Alternatively, click the "Changes" button (bottom-right corner) and click "Restore Defaults" to reset everything at once (only affects the config from my mod).
- Hamster Bedding Leaf Particles**
- Doubled the visual size of the Hamster Bedding particles to better match the leaves on the trees and on the hamster bed itself.
- Pink Petal Accessories**
- Added a new config toggle (true by default) to dynamically render Pink Petal accessories on the outside of equipped armor, so your hamster can be safe and fabulous simultaneously.
- Configurable 3D Visualizer Particles**
- Added a
Continuous Genetics Cylindertoggle to the config. When disabled, the 3D bounding cylinder generated by/ahp spawn_all_bases_3Dwill only render for the first second after spawning to reduce clutter. - Spawning & Testing Commands**
- Added
/ahp undo_last_spawn. Easily discards all hamsters spawned by your very last/ahp spawn...command. Perfect for when you set up a hamster display and then accidentally run the 2-million permutation command in the wrong location. - Overhauled the
/ahp spawn_all_possible_permutations_THIS_CAN_BREAK_YOUR_WORLDcommand. It is now called/ahp spawn_random_group <count>. - You must now provide a
<count>argument. It accepts standard numbers (e.g., 500) or anall_THIS_CAN_BREAK_YOUR_WORLDstring. - Hamsters are now spawned in a completely randomized order and placement on the grid.
- If the requested count is 5,000 or less, the hamsters are spawned synchronously and instantly without invoking the asynchronous batch-spawning system.
- Added five additional optional arguments to the 2D, 3D, and randomized spawn commands:
[spacing_multiplier],[match_player_yaw],[randomize_sitting],[randomize_sleeping], and[randomize_yaw]. These arguments allow you to expand or shrink the physical distance between the spawned hamsters, force the entire grid of spawned hamsters to face one direction, a random direction, and/or give them static poses to keep things more visually interesting. - Added a new argument to the
/ahp spawn_random_groupcommand calleduse_wild_overlay_rules_for_breeding_overlays. Allows you to spawn a more realistic/natural looking random group of hamsters. - Added a new
<pose>argument to the/ahp spawn hamstercommand, allowing you to specify sitting, sleeping, idle, or none. - Added personality ID's for command-spawned hamsters. The random sitting/sleeping poses are based on that ID, so they will retain those poses even after being tamed.
- Updated the
Admin Commandschapter in the *Hamster Tips* guidebook to include descriptions for these new commands and arguments. - Hamster Bed Placement**
- Placing down a new hamster bed no longer forces the hamster to sleep in it immediately unless the conditions are correct (i.e., time of day, config settings).
- Wandering Hamster Sitting**
- Hamsters linked to a bed will no longer automatically sit down when their owner logs out or changes dimensions, as long as the bed is still intact.
### Fixed
- Hamsters Falling Into End Portals**
- Hamsters that wander into the exit End Portal will now bounce right back out, complete with particle and sound effects.
- Prevents them from teleporting to the Overworld spawn coordinates and getting lost.
- Added a toggle to the config to revert to standard vanilla behavior if desired.
- Hamster Yeet & Evilcraft Bug**
- Resolved an bug that prevented hamsters from being thrown on Forge and NeoForge dedicated servers, caused by environment annotations running on the server thread. Super niche little insect that slipped by because it doesn't exist on Fabric. You should be able to throw your hamsters in multiplayer again!
- This also resolves a server startup crash when playing with EvilCraft, which attempts to instantiate the projectile to check its blood levels. Lol.
- Food Item Stacking**
- Resolved an issue on 1.21.1 where the configurable food items became unstackable in the inventory GUI after being split or spread.
- Implemented a stable ComponentMap caching system to ensure GUI right-click dragging correctly identifies dynamic food stacks as equal.
- Sliced Cucumber Feeding**
- Resolved a bug where already-tamed hamsters would refuse to eat their taming food (e.g. Sliced Cucumber) to heal or breed.
- Projectile Accessories**
- Fixed a visual bug where a hamster's equipped armor and accessories would temporarily vanish while they were airborne during a throw.
- Server Performance**
- Resolved a few pathfinding and AI issues where tamed hamsters following the player would sometimes experience server-tick lag spikes. Usually you wouldn't notice these unless you had a lot of hamsters following you at once.
- Wander Mode Override**
- Resolved a bug where disabling Wander Mode in the global config wouldn't stop already-wandering hamsters from lingering around their beds.
- Cheese Item Texture**
- Finally fixed the 99% transparent pixel in the bottom left corner of the cheese item texture. I only recently realized what was causing it to look so strange. Lol
- Console Log Spam**
- Resolved an issue where players with internet disabled (or those playing in regions where GitHub is blocked) would receive a massive, screen-filling error stack trace in their console every 5 minutes when the mod silently checked for updates in the background. Background network failures are now politely logged as a single warning line.
- Resolved an issue where the genetics engine would spam the server console with warnings when attempting to generate wild overlays for hamsters with extremely bright base coats (like Coconut).
- Sweet Potato Easter Egg**
- Renaming a hamster to "Sweet Potato" now correctly applies the easter egg texture without accidentally deleting the hamster's eyes, skin layer, and accessories. So that's good.
- Resolved an issue where the effects would trigger immediately upon renaming a hamster via the GUI, before the screen was closed.
- Resolved an issue where the affects would not trigger at all on 1.20.1 if a hamster was renamed via the GUI.
- Missing Vanilla Tags**
- The custom AHP Sunflower block is now properly registered under the vanilla
#minecraft:flowersand#minecraft:tall_flowerstags. This resolves compatibility issues with mods like Alex's Mobs that rely on these tags to identify flowers in the world. - Flashback Mod**
- Resolved a server crash that occurred when scrubbing through replay timelines using the Flashback mod, caused by missing NBT data on Hamster Beds.
- Resolved a persistent desync issue where shoulder hamsters would disappear when scrubbing backwards or jumping to different points on the replay timeline. Future replays will hopefully be fixed via a periodic server-side data sync that runs once per second.
- File Parsing Crashes**
- Fixed a crash that occurred when reading corrupted
.jsoncache files for the supporter perk system. It will now safely ignore the corrupted file and download a fresh copy from the internet. - Guidebook Server Synchronization**
- Resolved an issue where the "Missing Guidebook" chat warning would trigger repeatedly across multiple game sessions when playing on a dedicated server due to a configuration synchronization flaw.
- Fixed an issue where players were falsely led to believe they could locally disable Guidebook Auto-Delivery on dedicated servers. These settings now properly sync from the server to the client's config UI, reflecting the server's true authority over the book's delivery.
- Food Interactions**
- Fixed a bug where players could not toggle their hamster's sitting state if they were holding Hamster Food Mix or other food items.
- "Hampter"** Custom Name
- The "Use 'Hampter' as Default Name" config setting now properly reflects on the Jade HUD overlay and the Hamster Inventory screen.
- Cheek Pouch Allowed Items**
- Fixed an issue where all vanilla food items were forbidden in the Cheek Pouch on 1.20.1 due to a typo.
- Spawn Commands**
- Resolved an issue where AI-disabled hamsters generated by
/ahp spawn_all_bases_3Dwould sometimes suffocate and die if they spawned inside each other. They are now completely invulnerable until they are tamed/woken up. - Cheek Pouch Desync**
- Fixed an issue where a hamster's cheek pouches would visually deflate in heavily modded environments due to partial NBT syncing from mods like Jade.
- Guidebook Recovery Routing**
- The "Missing Guidebook" chat warning now correctly opens the root configuration menu so the recovery button is actually visible.

# **The Punchy Patch**
In addition to a bunch of new mini-games, idle animations and QoL features (including hamster armor trims & toggleable aggression states!), this patch introduces 5 new super cute, first-person animations to your rodent-handling experience, courtesy of the amazing **Punchy mod!** I've been working closely with [**@Dev Punchy Man**](https://modrinth.com/mod/punchy-fpa) to overhaul how it feels to pick up, pet, yeet, and dismount your hamsters.
### 👉🏼 [**Showcase video**](https://www.youtube.com/watch?v=YGRdjOTCMHo) 👈🏼
### Added
- New First-Person Animations** _(Optional: Requires Punchy v2.6.0+)_
- Note: The Punchy mod is **not a required dependency** for Adorable Hamster Pets. It is only required if you want to experience these specific new first-person animations listed below:
- Petting/Tickling Animation** _(Requires Punchy v2.6.0+)_
- You can finally pet your hamster! If you stare affectionately at your hamster for a **while sneaking** (about 15 seconds on average), you might just reach down, pick it up and give it some tickles. Comes with a new animation where the hamster flips over on your hand and asks for a belly rub! Also added a dedicated "Pet Hamster" keybind (unbound by default) for when you don't feel like waiting for the random chance to kick in.
- For those with the patience of a fruit bat, pressing your "Pet Hamster" key or clicking your mouse will cancel the petting animation. You don't need to be sneaking to use the keybind.
- If the hamster was sitting before you picked it up to pet it, it will remain seated when you place it back down, making this a great way to manually re-position tamed hamsters around your base.
- Shoulder Mounting Animations** _(Requires Punchy v2.6.0+)_
- Luring a hamster to your shoulder is no longer a boring teleport. You will now physically lift them up, complete with the hamster adorably bouncing on your hands or running up your arm. Three new unique animations; dynamically changing depending on their destination (left shoulder, right shoulder, head).
- Hamster Yeet Animations** _(Requires Punchy v2.6.0+)_
- Holding down the throw key (
G) grabs a specific hamster off your shoulder and holds it in front of your face. _(For more info, see "Hamster Yeet Mechanics" below)._ - While queued up, the hamster also plays its own new animation _(Requires Punchy v2.6.0+)_ where it eagerly wiggles its butt and kicks its back feet in anticipation of being hurled through the air.
- Releasing the throw key (
G) executes the throw, which is immediately followed by a new Punchy animation where you wave goodbye to your furry projectile. - If you release the key before the short charging period (
15 ticks) is over, you safely abort the throw. Your character will politely place the hamster back onto the exact shoulder it came from. - Hamster Yeet Mechanics**
- The Yeet Queuing System**
- Throwing a hamster is no longer instant. You must hold down the throw key (
Gby default) to "queue" a hamster for throwing. Includes new animations if the Punchy mod is installed. _(for more info, see "New First-Person Animations" above)_. - Releasing the throw key (
G) executes the throw. - If you release the key before the short charging period (
15 ticks) is over, you safely abort the throw. This charging period of15 ticksis not configurable, due to its duration needing to match the Punchy mod's animation. But it's quite short— only0.75 seconds— so hopefully it won't impact gameplay. - Hamsters Weigh Less**
- Added a
Downward Force (Gravity)slider to the config, allowing you to fine-tune how far hamsters fly without needing to increase their initial thrust. - Reduced the default gravitational force by ~30%, so hamsters will fly a little bit further now. (Useful for recording hamster flights with the Flashback mod, which gets buggy when entities are moving very quickly through the air).
- FOV Zoom**
- Added a smooth FOV zoom effect while queueing the Hamster Yeet, identical to drawing a vanilla bow. This FOV zoom will help indicate the new charging period for anyone who doesn't have Punchy installed, since the new animations are part of Punchy.
- Cooldown Recovery**
- If you're impatient, feeding your hamster will now incrementally reduce its throw cooldown (similar to how feeding accelerates baby growth).
- More Feedback**
- A new action bar message will let you know when the hamster has recovered from its concussion and is ready for launch.
- More Flower Accessories**
- Expanded the old "Pink Petal" accessory. You can now equip **any flower in the
#flowerstag** onto your hamster instead of just Pink Petals. - There are 12 unique textures. The texture assignment logic automatically scans the registry names of flowers. It uses an extensive list of color keywords and botanical families to ensure almost any flower you apply (even modded flowers) will have the correct color palette.
- The color assignment logic is completely data-driven. You can easily force a modded flower to use a specific color palette using standard Minecraft Item Tags (e.g., adding an item to
#adorablehamsterpets:flower_accessories/overlay_wither_rose). - For a tutorial, pop over to [**The Cheek Pouch**](https://discord.gg/w54mk5bqdf) Discord server, visit the **FAQ channel**, and search for _Custom Flower Accessories._
- Added new pages to the *Hamster Tips* guidebook explaining how the dynamic color assignment and tag overrides work.
- Shader LabPBR Material Support**
- All items, blocks, particles, and entities in this mod now include their own LabPBR-compliant Specular and Normal textures (with hamsters generating theirs procedurally), giving them detailed, per-layer PBR effects (emission, subsurface scattering, specular reflections, porosity, etc.) out-of-the-box with supported shaders.
- Must have your shader's material settings set to "LabPBR" or "Hardcoded + LabPBR"
- Metal armors have a "Vanilla-inspired" glossiness by default, but if you prefer hardcore realism and want them super metallic/reflective, I added custom sliders in the config allowing you to manually fine-tune the PBR values for each individual armor type.
- Added a
Max POM Depthslider to allow fine-tuning of the procedural 3D fur displacement (only works if your shader supports POM on entities, which is extremely rare). - Armor Trims**
- Hamster Armor can now be customized with vanilla armor trims in the Smithing Table.
- The following trims are currently available: Coast, Border, Vex, Eye, Sentry, Wild
- They will naturally glow in the dark and automatically have emission with shader mods like Iris.
- Added an
Emissive Armor Trimstoggle in the client config so you can disable the glowing effect if you hate fun and prefer a non-luminescent reality. - Added a
Trim Emissive Brightnessslider to give you precision control over exactly how blinding the neon lines should be. - Configurable Aggression States**
- Hamsters now have three distinct aggression states controlled by their diet.
- Pacifist:** Sneak + right-click them any vanilla flower (e.g.,
#minecraft:flowers). They become total hippies and will refuse to attack anything, even if you are being actively mauled. - Standard:** Sneak + right-click them Sunflower Seeds to factory-reset them back to their normal, wolf-like defensive behavior.
- Menace:** Sneak + right-click them a Spider Eye to unleash their inner demon. They will actively hunt down anything on the configurable "Menace Targets" list (which defaults to all monsters and bosses), and gain an expanded follow radius to give them more room to fight. If a target is outside their follow radius, they will move frantically at the edge of the tether.
- All trigger items are fully configurable, and changing a hamster's state produces a visual and audio confirmation.
- If you have jade installed, its overlay will display the hamster's current Aggression State when it is set to something other than the default, and can be toggled in the config alongside the other genetic displays.
- Hamster Tips Guidebook Entry**
- The *Hamster Tips* guidebook now features a dedicated "Aggression States" page to explain the new mechanics. It utilizes dynamic text injection to accurately display your configured trigger items, ensuring the book is always up-to-date even if a modpack creator changes the required diets.
- Pacifist Break:** Added a
Pacifist Break on Attackconfig toggle (false by default). When enabled, a passive hamster will automatically revert to neutral if it sees you attacking something. - Crop Harvesting**
- Tamed, wandering hamsters now possess an irrepressible desire for the occasional midnight snack.
- If they find a fully mature crop nearby and they have room in their cheek pouch, they will violently pounce on it, aggressively stuff the harvest into their cheek pouches, and accidentally replant some seeds in the process.
- Includes dynamic block particles and a leaf-crunching sound effect when pouncing on the crop block.
- Includes dynamic item particles when the hamster scoops up the dropped seeds and harvest items.
- Added a new
Crop Snacking Settingsallowing you to disable the feature entirely, tweak the cooldown, or add specific crops from their menu. - Added a new custom
#adorablehamsterpets:crop_itemsunion tag so hamsters can recognize and eat/harvest most modded crops and vegetables out of the box. - Added two new "Crop Harvesting" pages to the *Hamster Tips* guidebook explaining the feature.
- Swimming Mechanics**
- Added a new swimming animation loop for hamsters that accidentally fall into the water. This seems to happen a lot when they are snacking on crops so I thought it was a good time to add it.
- Replaced the Vanilla game's erratic swimming AI with a custom, smoother physics simulation that doesn't launch them out of the water every couple of seconds like a dolphin.
- Included 7 new unique water-swishing sound effects as part of the swimming animation.
- Hamsters can now dive underwater in persuit of items they want to steal/snack on.
- They will still do their best to avoid water the rest of the time, but now they don't look so broken when they inevitably fall into it.
- Hide & Seek Mini-Game**
- Tamed hamsters now occasionally get the urge to disappear into the woodwork.
- If they find a suitable hiding spot (bushes, chests, barrels, etc.), they will leap into it and vanish.
- You have a limited time to find them (configurable, ~45-60 seconds by default) before their short attention span gets the better of them. If you try to break or interact with the block they are hiding in during that time, you win! They will pop out and reward you with an item from their cheek pouches.
- If the timer runs out before you find them, they will emerge, sulk, and you get nothing.
- The block they are hiding in will occasionally jiggle, make noise, and spawn particles to help you locate them.
- You will also see a trail of subtle particles from your location directly towards the hiding spot, provided you are within 25 blocks of the hidden hamster.
- These effects will be *very* scarce at the start, but dynamically increases in frequency/intensity as the game progresses.
- Configurability:** Everything is customizable in the config. You can adjust the initiation chance, duration, block lists, and whether they are allowed to hide inside storage blocks like chests.
- Storage Crates**
- Thanks to [**@The Retro Stitcher**](https://theretrostitcher.com/) for helping to design new compacting storage crates for Acorns, Cucumbers, Green Beans, and Hamster Food Mix.
- Fully compatible with LabPBR shader materials out-of-the-box.
- "Hamtaro" Easter Egg**
- Renaming a hamster "Hamtaro" gives it a special texture. This functions identically to the "Sweet Potato" easter egg. Both base textures provided by [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com)!
- New "Panda" Overlay Pattern**
- Added a new "Panda" fur overlay pattern to the genetics engine, allowing you to breed panda-like hamsters. To get a "Panda" hamster, you'll need a Black base coat and a white overlay with the new "Panda" pattern. These can't be found in the wild, since black hamsters do not spawn with white overlays in the wild (breaks their camouflage). Thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for the Panda inspiration!
- 3 New Music Discs & Hamster Dancing**
- A legendary new **Cheese Music Disc** featuring the Adorable Hamster Pets theme song, created by yours truly. Can only be obtained by orchestrating a high-velocity, terminal collision between an airborne hamster and a Charged Creeper.
- Alternate Versions**
- The **Parmesan Music Disc:** Features an Orchestral remix of the Adorable Hamster Pets theme song. Piglins are apparently lactose aficionados. Trade a regular Cheese Music Disc with a Piglin to receive this highly adventurous, grated alternative.
- The **Blue Cheese Music Disc:** Features a Low-Fi remix of the Adorable Hamster Pets theme song. Obtainable by tossing a regular Cheese Music Disc into the End exit portal after defeating the dragon. The void will age the cheese and violently spit it back out at you.
- ⚠️ **Content Creators ↓**
- All three songs are **fully licensed** and safe for YouTube & Twitch monetization. Feel free to feature them in your videos!
- If playing in a Jukebox, nearby hamsters will dance to the music.
- Tried one of the remixes but not a fan? Surround the Blue Cheese or Parmesan discs with regular Cheese in a crafting table to restore them to their original 8-Bit glory.
- Added new advancements and guidebook pages hinting about how to obtain them.
- Modded Music Disc Support**
- Added a
Dancing Music Discsstring list in the config that contains a few strings by default:hamster,hampter, andhamtaro. If a jukebox plays a music disc containing any of these configured strings in its name, description, or lore (case-insensitive), nearby hamsters will dance to it. - Inter-Hamster Tag Mini-Game**
- Hamsters will now spontaneously instigate games of tag with each other.
- The instigator will sprint up to an unsuspecting victim, deliver a visual (damage-free) slap (using a new cowbell sound effect), and sprint away to begin the chase.
- If the chaser catches the instigator or if the 15-second timer runs out, the game ends and both hamsters celebrate.
- Tethering:** The instigator dynamically restricts its flee path to stay within 14 blocks of you (if tamed), ensuring they don't sprint off a cliff or into an unloaded chunk during the heat of the chase.
- Player Interruption:** Right-clicking either hamster while they are playing tag with each other will instantly break up the game and send them back to their normal routines, but will not reward you with a gift.
- Population-Independent Rarity:** The probability math dynamically adjusts based on the local hamster population. Whether you have 2 hamsters in your base or an apocalyptic horde, you will only see an average of 1 game per minute in that area.
- Configurability:** Added
Enable Hamster-vs-Hamster Tag,Average Minutes Between Games, andInter-Hamster Tag Durationsettings to the config. - New Ambient Sitting Animation**
- Added a new "sitting roll" animation where sitting hamsters occasionally roll on their backs. Comes with new sound effects, and it's configurable in the new "Ambient Sitting Behaviors" config group, which also controls cleaning frequency.
- Includes a "Cartoon Rolling Sound" config toggle. By default, the hamster's rolling SFX will include a cartoon-ish slide whistle. It's subtle, but some people might get distracted easily or prefer more realism.
- Hamster Armor Template Duplication**
- Hamster Smithing Templates can now be duplicated on a crafting table!
- Use 1 Template (top center), 1 corresponding material ingot/gem (center), and 7 Acorn Shards.
- Botanical Vandalism (Sapling Trimming)**
- You can now right-click any sapling with a pair of Shears to instantly turn it into a Dead Bush. This provides a much more accessible way to gather the necessary materials for crafting Hamster Bedding if you don't live near a desert.
- Added a new page to the *Hamster Tips* guidebook detailing this mechanic.
- Free Bed Respawn Toggle**
- Added a config toggle to allow hamsters to respawn at their linked beds indefinitely without requiring a tribute item charge (like a Totem of Undying). Disabled by default.
- Dynamic Trees Compatibility**
- Added out-of-the-box support for [**Dynamic Trees**](https://modrinth.com/mod/dynamictrees) via some new config settings.
- Replaced hardcoded oak leaves checks with a new
Heistable Leaveslist in the config, allowing modpack makers to easily add other modded leaves or trees to the heist feature. - Added a new
Heistable Logslist to theTree Heist Settingsconfig, similar to theHeistable Leaveslist. This means you can now start a tree heist by throwing the hamster at a branch or the trunk. - Developed a dumber but more compatible canopy-mapping algorithm that activates automatically if
Dynamic Treesis installed, ensuring heist still works without the vanilla leaves' internaldistance from trunkproperty. - Acorn Note:** The Dynamic Trees mod adds their own type of acorns and drop methods. When that mod is installed, the only way to get the specific acorns from my mod is through the Tree Heist.
- Dehydration and NutritionZ Compatibility**
- Added built-in datapacks for the [**Dehydration**](https://modrinth.com/mod/dehydration) and [**NutritionZ**](https://modrinth.com/mod/nutritionz) mods. Cucumbers will now hydrate you, and Cheese will finally clog your arteries properly.
- Combustible Acorns**
- Acorns can now be used as furnace fuel, smelting exactly the same amount of items as a vanilla stick.
- Alternatively, placing an Acorn in the top slot of a furnace will smelt it down into a piece of Charcoal.
- World Gen Compatibility Enhancements**
- Added massive out-of-the-box biome compatibility configuration data for [**Oh The Biomes We've Gone**](https://modrinth.com/mod/oh-the-biomes-weve-gone), ensuring hamster variants properly disperse across their beautiful landscapes. Huge thanks to [**@jlk2003r**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for helping configure these lists!
- Create Mod Compatibility**
- Added out-of-the-box recipe compatibility for [**Create: Bitterballen**](https://modrinth.com/mod/create-bitterballen) and [**Create Crafts & Additions**](https://modrinth.com/mod/createaddition).
- You can now mill, crush, compact, roast, and smoke AHP Sunflower Seeds to progress through the Bitterballen tech tree seamlessly, bypassing the need to hunt down vanilla sunflowers. Thanks to [**@jlk2003r**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for teaching me about Create so I knew what recipes to add!
- Armor Tier Jumping**
- You can now upgrade Hamster Armor between any tiers using the Smithing Table (e.g., Iron to Diamond, Diamond to Netherite). Previously, all upgrades had to start from base Acorn Armor. You can also downgrade it... should you decide to do so.
- Infinite Bed Respawns**
- Added a new
Tribute One-Time Useconfig setting. When enabled, a bed only requires the tribute item (Totem of Undying by default) once, permanently unlocking infinite respawns for that specific bed and hamster. - Taming Feedback**
- The mod will now provide snarky chat feedback if you try to tame a hamster incorrectly (such as not sneaking or offering them the wrong food) and will point you to the guidebook for help.
- Hamster Bed Placement Safeguard**
- Unlinked hamster beds can no longer be placed in the world accidentally.
- Attempting to do so for the first time triggers an audible warning and chat message explaining that they must be linked to a hamster first.
- After receiving the warning, a 2-second cooldown begins. Once it expires, players are allowed to place the unlinked bed freely. The game remembers that you've been warned and won't bother you again.
- Added config settings under 'Hamster Beds & Wander Mode' to disable the warning entirely, or to clear your history so you can experience it all over again.
- The tooltips and guidebook entries have been updated to make the linking process ("right-click a hamster with bed in hand") much clearer.
- Global Notification Toggle**
- Added a
Server Disable Announcementsconfig setting. Server owners can now globally disable the notification bell icon for all connected players. - Smoker Support**
- Green Beans can now be cooked into Steamed Green Beans using a Smoker, which cooks them twice as fast as a standard furnace.
- Compostable Sunflowers**
- The custom Adorable Hamster Pets Sunflower can now be placed in a composter (matching the 65% compost chance of vanilla sunflowers).
- Plantable Acorns**
- Acorns can now be planted directly on dirt/grass to grow vanilla Oak Trees. Once placed they will become Oak Saplings.
### Changed
- Config GUI Major Overhaul**
- During development on v3.6.1, the mod's configuration file exceeded Minecraft's hard-coded networking limits due to a Fzzy Config NeoForge bug which I've already reported. As a work-around, the main config has been split into multiple smaller, organized configs. It needed to be done anyway, so I simultaneously re-organized everything, making it more intuitive to navigate.
- Dismount Keybinding Simplification**
- Removed the confusing config toggle that forced players to enable a custom keybind in the config before they could rebind the "Dismount Hamster" key in the
Controls > Key Bindsmenu. The keybind is now permanently exposed. - The "Dismount Hamster" keybind now utilizes an unbound fallback system. By default, the keybind is set to
Unbound, and the game will naturally listen to your vanillaSneakkey to dismount hamsters. However, if you manually assign a key to it in the controls menu, it will override the sneak behavior and listen exclusively to your custom key. - The default "Button-Press Behavior" config setting has been changed from
Single PresstoDouble Tapto prevent accidental dismounts when sneaking near ledges. Originally it was set to single press to mimic vanilla parrot behavior, but it's just so annoying. I finally can't stand it anymore. Lol. - Added a
Custom Key Behavior Overrideconfig toggle (true by default). When you bind a custom key for dismounting, it automatically overrides theDouble Tapbehavior and makes it aSingle Press. I assume if you assigned a dedicated key to it, you don't want to have to tap it twice. - Keybind Names**
- Renamed several of the key binds to make the
Controls > Key Bindsmenu more intuitive. - Hamster Attacking AI**
- Hamsters can no longer pathfind outside the follow radius when targeting entities. They will instead exhibit erratic behavior near the edge of the boundary.
- This prevents repetitive teleportation back to the player when the hamster is aggressively targeting something outside the follow distance.
- To compensate, follow distance has been increased by five blocks when the hamster is in MENACE mode.
- The Hamster Yeet**
- Throwing a hamster is no longer canceled/prevented if the player's crosshair is over non-solid blocks like tall grass, flowers, sugar cane etc.
- Reduced the default gravity applied to thrown hamsters by 30%, resulting in naturally longer, flatter arcs out-of-the-box. Hamsters will feel less "heavy" now during throws.
- Thrown hamsters now generate a shower of block-breaking particles upon impacting a surface.
- Resolved an issue where players throwing their hamsters very far away wouldn't hear some of the animation-based impact sounds due to vanilla audio distance attenuation.
- Hamster Tips Guidebook**
- "The Great Escape" has been renamed to "Beds & Wander Mode," and "Acorn Armor" has been renamed to "Tree Heist & Armor" so you guys won't keep coming into my Discord server asking how the beds work and where to find acorns 😂
- This has another super useful perk: Now whenever you search through the guidebook for a specific topic, you can search for things like "bed," "tree heist," or "armor" and those specific entries will pop up in the results.
- Now utilizes dynamic text injection to accurately display your configured resurrection tribute items. So now if a server owner or modpack creator changes the default item from a Totem of Undying, the guidebook will update itself automatically.
- Tag Mini-Game**
- Wild hamsters can no longer initiate a game of tag to prevent interference with taming. Tamed hamsters can still play tag with strangers if enabled in the config.
- The game will no longer randomly start while you are sneaking, preventing interference with petting.
- You can now manually start a game of tag on-demand by rapidly sneaking and un-sneaking while maintaining eye contact with a tamed hamster.
- Since there is now a manual trigger, the chance of the game starting is now much lower. You will need to stare at a hamster for ~15 seconds on average for the game to automatically start.
- Starting a game of tag now plays a sound, spawns particles, and displays an action bar message to clearly indicate that it is a fun event and not a bug.
- Hamsters will now lovingly slap you (applying knockback and brief nausea, but no damage) when the game starts.
- Added a 1-second interaction cooldown when the game starts to prevent accidentally catching the hamster immediately.
- Genetics & Color Groups**
- Renamed the
ROSEcolor group toCHERRYsince the only hamster in that group is the "Pearl Rose" hamster, which is basically pink anyway. - Added a new
RUSTcolor group. The "Rust" hamster has officially been evicted from theORANGEcategory, allowing it to have its own dedicated spawning rules. - Spawning Config Overhaul**
- Reorganized the World Gen config UI to clearly separate the global "Allow/Prevent Spawns" lists from the "Region-Based Color Filters". It now clearly explains the "filter funnel" concept so you know exactly why the Plains environment acts as a catch-all.
- Expanded the procedural spawning logic from 10 environments to 12, giving modpack makers perfect 1:1 granular control over all 12 hamster color groups.
- The Wildcard:** Added a "Priority 1: Wildcard" zone. Allows server owners to surgically extract specific biomes from broader categories and assign them unique colors without overhauling the other lists. (i.e., If you wanted to separate the environments in which Light Gray and Dark Gray hamsters spawn, now you can do so).
- Sky Environments:** Added a dedicated zone for floating island biomes to host the
SKYcolor group. Vanilla players— no need to freak out; there's still a 15% chance to findSKYhamsters instead ofWHITEin snowy areas. - Cherry Environments:** Extracted Cherry Groves out of the Magical environments so they can be balanced independently. Defaults to 100%
CHERRYhamsters. - Auburn Environments:** Added a dedicated zone targeting Badlands (and modded autumnal forests with red trees if you like). This is the exclusive new home for
RUSThamsters. (ORANGEhamsters will no longer spawn in Badlands by default). - Re-balanced Weights:** Adjusted the default spawning weights across the
Icy,Magical, andSnowyenvironments to accommodate the new color zones. - ⚠ Important Config Note for Existing Worlds**
- If you are updating an existing modpack, your old config files will obstinately hold on to their old settings. This is good, otherwise you would lose all your work every time I pushed out an update. However, this means that in order to see these new default spawn weights, you will need to right-click specific settings in the config screen and select "Restore Defaults." Alternatively, click the "Changes" button (bottom-right corner) and click "Restore Defaults" to reset everything at once (only affects the config from my mod).
- Hamster Bedding Leaf Particles**
- Doubled the visual size of the Hamster Bedding particles to better match the leaves on the trees and on the hamster bed itself.
- Pink Petal Accessories**
- Added a new config toggle (true by default) to dynamically render Pink Petal accessories on the outside of equipped armor, so your hamster can be safe and fabulous simultaneously.
- Configurable 3D Visualizer Particles**
- Added a
Continuous Genetics Cylindertoggle to the config. When disabled, the 3D bounding cylinder generated by/ahp spawn_all_bases_3Dwill only render for the first second after spawning to reduce clutter. - Spawning & Testing Commands**
- Added
/ahp undo_last_spawn. Easily discards all hamsters spawned by your very last/ahp spawn...command. Perfect for when you set up a hamster display and then accidentally run the 2-million permutation command in the wrong location. - Overhauled the
/ahp spawn_all_possible_permutations_THIS_CAN_BREAK_YOUR_WORLDcommand. It is now called/ahp spawn_random_group <count>. - You must now provide a
<count>argument. It accepts standard numbers (e.g., 500) or anall_THIS_CAN_BREAK_YOUR_WORLDstring. - Hamsters are now spawned in a completely randomized order and placement on the grid.
- If the requested count is 5,000 or less, the hamsters are spawned synchronously and instantly without invoking the asynchronous batch-spawning system.
- Added five additional optional arguments to the 2D, 3D, and randomized spawn commands:
[spacing_multiplier],[match_player_yaw],[randomize_sitting],[randomize_sleeping], and[randomize_yaw]. These arguments allow you to expand or shrink the physical distance between the spawned hamsters, force the entire grid of spawned hamsters to face one direction, a random direction, and/or give them static poses to keep things more visually interesting. - Added a new argument to the
/ahp spawn_random_groupcommand calleduse_wild_overlay_rules_for_breeding_overlays. Allows you to spawn a more realistic/natural looking random group of hamsters. - Added a new
<pose>argument to the/ahp spawn hamstercommand, allowing you to specify sitting, sleeping, idle, or none. - Added personality ID's for command-spawned hamsters. The random sitting/sleeping poses are based on that ID, so they will retain those poses even after being tamed.
- Updated the
Admin Commandschapter in the *Hamster Tips* guidebook to include descriptions for these new commands and arguments. - Hamster Bed Placement**
- Placing down a new hamster bed no longer forces the hamster to sleep in it immediately unless the conditions are correct (i.e., time of day, config settings).
- Wandering Hamster Sitting**
- Hamsters linked to a bed will no longer automatically sit down when their owner logs out or changes dimensions, as long as the bed is still intact.
### Fixed
- Hamsters Falling Into End Portals**
- Hamsters that wander into the exit End Portal will now bounce right back out, complete with particle and sound effects.
- Prevents them from teleporting to the Overworld spawn coordinates and getting lost.
- Added a toggle to the config to revert to standard vanilla behavior if desired.
- Hamster Yeet & Evilcraft Bug**
- Resolved an bug that prevented hamsters from being thrown on Forge and NeoForge dedicated servers, caused by environment annotations running on the server thread. Super niche little insect that slipped by because it doesn't exist on Fabric. You should be able to throw your hamsters in multiplayer again!
- This also resolves a server startup crash when playing with EvilCraft, which attempts to instantiate the projectile to check its blood levels. Lol.
- Food Item Stacking**
- Resolved an issue on 1.21.1 where the configurable food items became unstackable in the inventory GUI after being split or spread.
- Implemented a stable ComponentMap caching system to ensure GUI right-click dragging correctly identifies dynamic food stacks as equal.
- Sliced Cucumber Feeding**
- Resolved a bug where already-tamed hamsters would refuse to eat their taming food (e.g. Sliced Cucumber) to heal or breed.
- Projectile Accessories**
- Fixed a visual bug where a hamster's equipped armor and accessories would temporarily vanish while they were airborne during a throw.
- Server Performance**
- Resolved a few pathfinding and AI issues where tamed hamsters following the player would sometimes experience server-tick lag spikes. Usually you wouldn't notice these unless you had a lot of hamsters following you at once.
- Wander Mode Override**
- Resolved a bug where disabling Wander Mode in the global config wouldn't stop already-wandering hamsters from lingering around their beds.
- Cheese Item Texture**
- Finally fixed the 99% transparent pixel in the bottom left corner of the cheese item texture. I only recently realized what was causing it to look so strange. Lol
- Console Log Spam**
- Resolved an issue where players with internet disabled (or those playing in regions where GitHub is blocked) would receive a massive, screen-filling error stack trace in their console every 5 minutes when the mod silently checked for updates in the background. Background network failures are now politely logged as a single warning line.
- Resolved an issue where the genetics engine would spam the server console with warnings when attempting to generate wild overlays for hamsters with extremely bright base coats (like Coconut).
- Sweet Potato Easter Egg**
- Renaming a hamster to "Sweet Potato" now correctly applies the easter egg texture without accidentally deleting the hamster's eyes, skin layer, and accessories. So that's good.
- Resolved an issue where the effects would trigger immediately upon renaming a hamster via the GUI, before the screen was closed.
- Resolved an issue where the affects would not trigger at all on 1.20.1 if a hamster was renamed via the GUI.
- Missing Vanilla Tags**
- The custom AHP Sunflower block is now properly registered under the vanilla
#minecraft:flowersand#minecraft:tall_flowerstags. This resolves compatibility issues with mods like Alex's Mobs that rely on these tags to identify flowers in the world. - Flashback Mod**
- Resolved a server crash that occurred when scrubbing through replay timelines using the Flashback mod, caused by missing NBT data on Hamster Beds.
- Resolved a persistent desync issue where shoulder hamsters would disappear when scrubbing backwards or jumping to different points on the replay timeline. Future replays will hopefully be fixed via a periodic server-side data sync that runs once per second.
- File Parsing Crashes**
- Fixed a crash that occurred when reading corrupted
.jsoncache files for the supporter perk system. It will now safely ignore the corrupted file and download a fresh copy from the internet. - Guidebook Server Synchronization**
- Resolved an issue where the "Missing Guidebook" chat warning would trigger repeatedly across multiple game sessions when playing on a dedicated server due to a configuration synchronization flaw.
- Fixed an issue where players were falsely led to believe they could locally disable Guidebook Auto-Delivery on dedicated servers. These settings now properly sync from the server to the client's config UI, reflecting the server's true authority over the book's delivery.
- Food Interactions**
- Fixed a bug where players could not toggle their hamster's sitting state if they were holding Hamster Food Mix or other food items.
- "Hampter"** Custom Name
- The "Use 'Hampter' as Default Name" config setting now properly reflects on the Jade HUD overlay and the Hamster Inventory screen.
- Cheek Pouch Allowed Items**
- Fixed an issue where all vanilla food items were forbidden in the Cheek Pouch on 1.20.1 due to a typo.
- Spawn Commands**
- Resolved an issue where AI-disabled hamsters generated by
/ahp spawn_all_bases_3Dwould sometimes suffocate and die if they spawned inside each other. They are now completely invulnerable until they are tamed/woken up. - Cheek Pouch Desync**
- Fixed an issue where a hamster's cheek pouches would visually deflate in heavily modded environments due to partial NBT syncing from mods like Jade.
- Guidebook Recovery Routing**
- The "Missing Guidebook" chat warning now correctly opens the root configuration menu so the recovery button is actually visible.

# **The Procedural Genetics Update**
Hamsters now utilize a fully procedural and configurable genetics engine with **3,158** new wild variants, **2,285,046** potential breeding outcomes, recessive red eyes, 13 new advancements, and a guidebook update that explains everything. Added comprehensive breeding settings to balance obsessions with server tick speed (looking at you, Janet). Also many bugs were squashed, and hamsters learned to play tag and spit out gifts from their cheeks. Make sure you update Patchouli to the latest version or your game won't launch!

### Added
- Procedural Genetics & Texture System**
- Procedural Genetics Engine**
- Hamsters are no longer pre-defined, hardcoded variants. Every hamster now possesses a fully serialized
detailing its precise genetic makeup across six distinct traits.This was accomplished by developing a 3D Hue/Saturation/Brightness (HSB) Cartesian color space. The mod uses this to mathematically map the exact color coordinates of every hamster variant into a three-dimensional neural network, which is dynamically used to calculate genetic relationships, mutations, overlay exclusion rules, and environment-spawning rules on the fly. I got the idea for creating the textures programmatically like this because that's how I made the original textures in Photoshop— using various Gradient Maps applied to a single, grayscale texture. Then I realized Java code can do the same thing! The total number of unique hamster types that spawn in the wild is now **3,231** by default, and the number of genetically inheritable hamster permutations from breeding is now **over 2.2 Million**. Want to understand the math?** Keep reading below— look for the _"Advanced Spawning & Testing Commands"_ section. I have added all sorts of fancy commands and tools to walk you through the breeding system in a way that is (hopefully) easy to understand. Dynamic Palette Swapping** Built an optimized, client-side dynamic texture generator. Instead of bloating your hard drive with over 2 million distinct PNG files, the mod dynamically recolors grayscale fur templates at runtime using custom genetic palette hex code data I designed based off my Photoshop workflow, then mixes them with hard-coded PNGs from the community. I realized the original hamster variants were just gradient maps applied to a grayscale texture in Photoshop. So, naturally, I invested an unreasonable amount of effort rebuilding Photoshop's Gradient Map tool inside Java. Does this save file space? Sort of, though tiny PNGs don't take up much space anyway. But it makes the system infinitely scalable. If I add just one new grayscale pattern or community-made texture in the future, the Java math will automatically multiply it across every single other variant in the game. For now, consider it an over-engineered proof of concept. Community Hamster Textures** Developed a parallel pipeline that automatically scans, analyzes, and genetically categorizes static, community-made PNG textures directly from the mod's JAR file. These static textures are seamlessly integrated into the procedural breeding pool alongside my programmatic colors. The rendering engine can automatically composite custom community textures into overlay masks. This means hamsters can spawn with community-made palettes serving as the color for their overlay spots and splotches! Thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com), we have 18 brand-new base hamster variants spawning in the wild! (Including *Cheesecake Mocha, Blue Fawn, Pearl Rose, Sable,* and 14 more). You can see them all in-game using the new spawn commands (see below). Expanded Overlays** Overlays are no longer just white. Wild Overlays:** Naturally spawning hamsters can now have overlays in any color that is closely related to White, Cream, or Gray, with a few configurable exceptions. To keep things looking natural, the default config ensures wild overlays are always brighter & less saturated than the base coat, Cream is disallowed on a Lavender or Blue base coat, and cave-spawned hamsters can only receive Gray overlays to help them blend in. Breeding Overlays:** A completely new secondary overlay layer, unlocked exclusively through breeding (45% chance when two first-generation wild hamsters breed). These are chosen based on the midpoint between the parents' base color in the 3D color-space coordinate system, with a bit of jitter so the baby won't always look the same when you breed two parents repeatedly, so the possibilities are nearly endless. These overlays will mathematically avoid copying the same shape/pattern as the wild overlay, to ensure they are not hidden/covered up by it. Breeding & Lifecycle Mechanics** Breeding Inheritance and Visualization Tool** Here's how it works:** When breeding two hamsters together, the color for the baby (and its overlay colors) are chosen based on a connected line between the two parents in the 3D color-space coordinate system. This means babies will tend towards the mathematical center, but occasionally one parent's color traits will strongly dominate the outcome, mimicking real-world genetics and providing visual variety within a single hamster family even if you breed the same two parents together repeatedly. Outcome Visualizer:** You can right-click two hamsters inside the 3D variants layout ( /ahp spawn_all_bases_3D) with the Hamster Tips guidebook to visualize the genetic probability distribution for their offspring via a cloud of Wax On particles. The particle spawning logic uses the exact same probability math that is used when creating babies, so it gives you a perfectly accurate representation of potential outcomes.Config Settings and Real-time Controls** Genetic Variance**: Adjusts how much a baby's base color can deviate from the exact center between its parents. Think of this as the "length" of the line between the parents. Genetic Mutation Rate**: Adjusts the random color scatter/mutations applied to babies. Think of this as the "thickness" of the line. Simulated Offspring Per Second**: Adjust the density of the 3D visualizer particle cloud. Each particle represents a potential baby. Real-time Controls:** While holding the guidebook, you can dynamically tweak the shape of the genetic probability cloud using the arrow keys: Left/Right Arrows adjust Genetic Variance; Up/Down Arrows adjust Genetic Mutation Rate. Server and Client Sync:** Since the particle visualizer is driven by the literal server-side breeding math, which is driven by the config for your server, and the changes you make with the arrow keys directly alter that config, the changes will take effect immediately for any future babies. Recessive Eye Genetics** Hamsters now possess dominant (Black) and recessive (Red) eye genetics. Red eyes do not exist in the wild. They are genetically tied to the "diluteness" (brightness/saturation) of the hamster's coat. A fully dilute hamster has up to a 50% chance of spawning with a recessive red eye gene. By selectively breeding highly dilute hamsters, players can uncover carriers ( Br) and eventually breed Red-Eyed (rr) variants. Uses punnet squares.Baby Growth Mechanics** You can now feed baby hamsters standard hamster food items to accelerate their growth. To balance this with their natural pickiness, a new config option ( Disable Baby Food Refusal) allows you to bypass their desire for dietary variety specifically for babies if you want. This is turned off by default, so to bypass their pickiness you'll need lots of **Hamster Food Mix** if you want to quickly grow them up.Feeding baby hamsters visually and mechanically accelerates their growth in smooth, continuous increments, similar to vanilla horses. Their "extra big head" proportions scale dynamically as they grow. Breeding Limitations** Added comprehensive config settings to manage hamster breeding for server owners who want to keep the population under control. Added a global Enable Breeding toggle (on by default) to instantly shut down all romance.Added a configurable Max Breeding Cycles limit per hamster to stop them from infinitely multiplying (off by default).Added a Limit Breeding By Player toggle. (also off by default). Limits can be assigned per-player based on Minecraft days or Real Life days, or simply capped as a lifetime maximum limit. Includes feedback to explain what's happening when attempting to over-feed beyond the limit.Added a /ahp reset_player_breeding_history command for server operators to reset their own breeding history.Added a /ahp reset_hamster_breeding_history command for server operators to reset a specific hamster's timesBred quota to zero.Added a convenient "Reset Breeding History" button in the Config screen that executes the command for the user (requires OP permissions). Configurable Litter Size** Added to config sliders allowing you to set the minimum and maximum litter size when hamsters get into hanky-panky. The final size of the litter will be a random number between the min and max. Breeder Whitelist** Added a config list allowing specific players to bypass the global breeding ban. In case your server needs a designated rodent baron. Post-Breeding Animation** Hamsters will now crouch down and lovingly inspect their baby(s) after the litter is born, spawn heart particles, and make affectionate sounds shortly after successfully contributing to your growing population problem. Wild Baby Configuration** Added Babies Spawn Wild setting. When enabled, babies are born feral and do not inherit their parent's ownership status, letting multiplayer groups decide who claims them.When untamed, babies no longer flee from players, making them easier to manage. Parent-Following** Babies will now randomly select a parent to follow until adulthood, instead of following their owner. Wild baby hamsters will switch to following the player if their parent is currently mounted on the player's shoulder. They will automatically resume following the parent once it is dismounted. If you want the baby to follow you instead, you must first tame it, then you can break its connection to the parent by right-clicking it with a Lure Item (Cheese by default). Added a config toggle to disable the action bar message that warns you when a newly tamed baby hamster refuses to follow you because it's still attached to its parent. Age Tracking** Hamsters now track their absolute lifetime age in ticks. Wild hamsters spawn with a random age between 1 and 30 days. Added /ahp set_age command to manually override a hamster's age (since older hamsters will start at 0 days old upon updating to this version of the mod). It accepts units (days, months, years) and provides autocomplete suggestions.If you do not specify a target, it will automatically apply to the hamster you are currently looking at. The Jade HUD overlay displays the hamster's age alongside its genetic data. Added a new Display IRL Age config setting that dictates how fast the hamster ages. If true, their age progresses at 1/72nd the normal speed (matching the real-world 24-hour cycle).Performance Improvements** Significant Overall Improvements** Flattened the entire visual render layer stack (base coat, wild overlays, breeding overlays, skin, eyes, armor, and accessories) into a single, dynamically composited texture at runtime. This completely eliminates all secondary GeoRenderLayer passes. Every hamster, regardless of its complex genetics or equipped items, now costs exactly one draw call to render (previously it was anywhere from 2 to 8!), resulting in a massive performance boost. Especially noticeable when numerous hamsters are on screen at the same time.Bare-Bones Ultra Performance Mode** Added a new Performance Mode toggle in the config (and an assignable keybind) designed specifically for viewing absurd numbers of hamsters simultaneously without melting your GPU.When enabled, it bypasses the dynamic texture engine entirely (falling back to a single flat texture) and hides almost all the model's geometry. The hamsters essentially become grayscale cubes, stripping away nearly all matrix-calculation overhead. The Jade HUD overlay will still display their exact genetic information, because the server never forgets what they are actually supposed to look like. New Config Settings** Wild Overlay Configurability** Added new Allowed Wild Overlay Zones list to the World Gen & Loot config. This allows server owners/modpack makers to explicitly control which color zones the genetics engine is allowed to use when picking an overlay for a naturally spawning hamster. Defaults to natural colors (WHITE, LIGHT_GRAY, DARK_GRAY, and CREAM).Added new Restricted Base Colors and Clashing Overlay Colors lists. By default, these prevent CREAM and DARK_GRAY wild overlays from spawning on top of BLUE and LAVENDER base coats, as these color combinations tend to look a bit strange visually.Added new Enforce Brighter Overlays and Enforce Muted Overlays toggles. Allows players to disable the overlay filtering that prevents saturated colors (like Cream) from spawning on muted bases (like Black) and darker colors from being used as overlays on top of lighter bases.Modifying the overlay settings can dramatically change the number of possible combinations for wild hamsters (3,231 by default). Red Eye Config Toggle** Don't like the red eye hamsters? You can visually disable that for your own client via a new config toggle, which makes them appear to have black eyes. Friendly Fire Config Toggle** Added Prevent Owner Friendly Fire to the Core config toggles.When enabled, players can no longer accidentally damage their own tamed hamsters. Disabled by default to remain vanilla-friendly. In the next update (hopefully), this setting will be tied to a new item: the **Acorn Ring**. I also plan to integrate with the **Trinkets** mod so you can use a trinket slot for it. Configurable Cuisine** You can now configure the nutrition and saturation values for all food items added by the mod (Cucumbers, Green Beans, Food Mix). Changed nutrition/saturation values are dynamically reflected in AppleSkin's "on-eat" HUD preview. **Unfortunately due to major API changes between MC versions, this only works on 1.21.1.* Max Mounted Hamsters Config** Added a configuration slider under 'Shoulder Hamster Settings > Core Settings' allowing players to limit the maximum number of hamsters that can be mounted simultaneously (1 to 3). Gameplay Mechanics & Interactions** Tag Mini-Game** Hamsters can now initiate a playful game of tag. If you maintain eye contact with a hamster for a few seconds, it will squeak and excitedly run away. The Chase:** The hamster will flee if you get too close and stop to playfully taunt you if you fall too far behind. Payoff:** Successfully "catching" (right-clicking) the hamster before it gets bored ends the game triggers a celebration. The hamster will then spit out a random item from its cheek pouches as a gift (pulling from the configurable cheek pouch loot lists). Stranger Danger:** By default, you can play tag with wild hamsters and hamsters owned by other players. (Can be disabled in config). Configurable Limits and Rewards** Added configs to control how often they want to play, the cooldown between games, and an anti-abuse cap on how many times a single player can play the game per in-game day (so they can't farm rewards). Added configs to control rewards: By default, hamsters will randomly pick an item from their configurable "Cheek Pouch Loot" list (the list of potential items a wild hamster might spawn with). The item does not have to be in the hamster's cheek pouch for it to give it as a gift. That can be disabled, in which case the hamster will choose the gift from a separate "Custom Tag Rewards" list in the config, which means you can make your hamster give you a diamond or any modded item (or whatever you want) when you catch it after a game of tag. Only server moderators can modify this of course. Dynamic Gaze** Hamsters will now sustain eye contact with you indefinitely, provided you are nearby and continue looking back at them, and of course as long as they don't start a game of tag. Hamster Yeet Overhaul** Thrown hamsters are now officially registered as ProjectileEntity instances while airborne. This provides automatic, out-of-the-box compatibility with external mods that use targets or hoops (such as the Tin Hoops in Caverns and Chasms).Thrown hamsters now experience dynamic physics upon impact. They will ricochet backward off of walls and entities, or skip forward when hitting floors and ceilings. Thrown hamsters now dynamically query and broadcast the native sound of the block or entity they strike (including modded blocks/entities). Impact physics are magnified when hitting Slime blocks, and completely absorbed by Honey blocks. Added a new config toggle (true by default) allowing thrown hamsters to damage their owner. Throwing your own rodent straight up in the air will now result in a realistic, concussive reunion on the way back down. Precision Tree Heists** Right-clicking Oak Leaves with a lure item (Cheese) while a hamster is on your shoulder will now initiate a "Precision Tree Heist." This sets that specific leaf block as the guaranteed exit point for the hamster. While a precision heist is active, right-clicking in the air with the lure item will set the hamster's exit direction to match the direction you are currently looking. Why?** This allows you to precisely control the exact block and angle by which your hamster will exit the tree, which makes for much more predictable recording sessions. Moonwalking Easter Egg** Name your hamster "Michael Jackson" or "Steve Irwin" and it will rotate backwards and remain that way until you change the name again. Expanded Default Diet** Hamsters can now eat seeds from almost any mod out-of-the-box. Added a robust union tag to the default config that automatically syncs with #c:seeds and #forge:seeds to ensure compatibility across all versions and mod loaders.Failsafes & Rescues** Teleport Rescue Protocol** Overhauled how hamsters follow you across vast distances or dimensions (e.g., when using Waystones). Instead of relying on their tiny legs and pathfinding AI to catch up, your player code will now safely scoop up any actively following hamsters (and their babies if the babies are following them), hold them in a little NBT pocket while the world loads, and drop them at your new location 0.75 seconds later. Void Rescue Protocol** If a player falls into the void and dies with hamsters on their shoulders, the hamsters will no longer spawn in the void and immediately perish. The system will safely teleport them back to their linked bed. If they do not have a linked bed, they will be sent to the player's personal respawn point or the world spawn. UI, HUD, & Audio** Jade Integration** Added comprehensive Jade overlay integration that reveals a hamster's exact genetic makeup (base coat, wild overlay, breeding overlay, eye genotype, etc.) when you look at them. Enabled without needing to turn on debug mode to help with breeding. Fully customizable. Each setting comes with its own toggle, and you can decide which ones show up when you sneak to keep the Jade HUD de-cluttered. GUI Renaming System** Players can now rename their hamsters directly from the Hamster Inventory screen. Features dynamic down-scaling to ensure long names always fit perfectly within the UI constraints. An interactive pencil icon and underline display when hovering/typing. New Config Options ( UI & Quality of Life > Hamster Renaming)**Enable GUI Renaming: Master toggle for the feature.Consume Name Tag: Forces players to sacrifice a Name Tag from their inventory (or the hamster's cheeks) to finalize the rename.Pencil Icon Placement: Allows swapping the icon to the left or right of the text for those who read in different directions.New Audio & Visuals** Added a brand new anim_hamster_cheek_unload animation used for gifting items, complete with item and spit particle effects.Added 4 new scratching sound variations for the cleaning animation, and switched to keyframes for the SFX to make it less repetitive and more realistic. This also has the side effect of muting the sound effect if the hamster is not on screen, and thus not being rendered. This means you will no longer hear nearby hamsters cleaning unless you can also see them. Added dynamic item sounds (clink, squish, thud, etc.) to the new gifting sequence. Commands & Admin Tools** Advanced Spawning & Testing Commands** Added /ahp spawn hamster <basePalette> <wildPattern> <wildPalette> <breedPattern> <breedPalette> <eyes>. This command features a custom Brigadier auto-complete engine that suggests exact, human-readable palette and pattern names as you type, allowing you to easily test specific genetic combinations.Added /ahp spawn_all_bases_2D. Systematically lines up every single hamster color base in the game (including custom community additions), sorted cleanly into rows by their dynamically determined, mathematical color zone.Added /ahp spawn_all_bases_3D. Spawns the hamsters hovering in a physical 3D "cylinder" representing their Hue/Saturation/Brightness coordinates. This is useful for the **Breeding Inheritance and Visualization Tool** (see below).Hue** = the degree of the circle (0-360) Saturation** = the radius of the circle (more saturated colors are closer to the edge) Brightness** = the height of the cylinder (brighter hamsters are closer to the top) By default, each /ahp spawn_all_bases... command spawns just the 45 base colors, but each one comes with 3 optional arguments to change the number of hamsters spawned: 1. [with_wild_overlays] Displays all 3,231 hamster variants that can spawn naturally in the wild.
2. [with_sample_breeding_overlays] Displays genetic combinations of every wild hamster but adds in a small sample of three breeding overlays (Tortoise Shell, Silver, and Rust). Due to the triple-multiplication math involved, this heavily increases the total number of hamsters spawned (from 3,231 up to 9,693) creating a much bigger display.
3. [author] only uses color palletes from a certain author (e.g., jimcerberus or default).
- Added
/ahp spawn_all_possible_permutations_THIS_CAN_BREAK_YOUR_WORLD. Exactly what it sounds like. Don't run it unless you have a super-flat world, a fire extinguisher for your PC, and a lot of patience. Note that every time I have run this command, my server tick speed never quite returned to baseline— even after deleting all the hamsters that were spawned using /kill @e[type=!player].Added /ahp print_genetics_report command, allowing server operators to recalculate and view the current 3D color-space math of the genetics engine at runtime. Useful because it dynamically updates its readout based on your exact AhpWorldGenConfig wild overlay settings, so you can see how your changes are affecting the total possible variant numbers without having to spawn them all.Tree Heist History Command** Added /ahp reset_tree_economy for quick clearing of tree depletion memory without needing to open the config screen.Advancements** Advancement: Carat Confusion** Triggers when a hamster leads you to Gold Ore instead of Diamond. Advancement: Load-Bearing Human** Triggers when you mount 3 hamsters simultaneously (Right, Left, Head). Genetic Progression Advancements** Added "The Collector" advancement path tracking unique wild variants tamed (up to dynamic maximum based on configuration limits). Added "The Breeder" advancement path tracking unique bred combinations (up to 1,000,000). Added a conditional advancement "Seeing Red" for successfully breeding the recessive eye trait. Does not trigger if red eyes have been turned off in the config. Implemented high-performance, non-bloating NBT storage using IntArrays to track thousands of HamsterGenome hashes without lagging the player entity.Guidebook Enhancements** Guidebook Delivery Fallback** Added a new configuration option that acts as a fallback for modpacks that disable auto-guidebook delivery on login. If enabled (default), players will automatically be given the Hamster Tips guidebook and receive a chat prompt the very first time they spot a wild hamster from <=10 blocks away. Targeting calculation includes wiggle room to ensure the event triggers even if the player's crosshair isn't perfectly on the hamster's hit box. Only triggers once, and only if the player has never yet received the guidebook (regardless of current inventory status). Lectern Reading** Added code for placing the Hamster Tips guide book into a lectern and an event handler so you can read it. You can now display your rodent knowledge in your base or wherever. Hamster Tips Guidebook Improvements** The *Hamster Tips* guidebook now uses a custom string processor to pull live data directly into the text, so I can do things like automatically displaying the exact number of mathematically possible wild variants or the name of your dynamically configured Lure Item instead of hardcoding "Cheese". Updated the "Regional Rodents" entry to explain the new biome-adaptive color logic, Wild Overlays and Jade integration. Added a new "Breeding" entry in _The Hamster Life_ chapter detailing the genetic mechanics, recessive red eyes, and feral youth mechanics. Added a new "Admin Commands" entry in _The Kitchen Drawer_ chapter detailing the various new (and old) commands the mod has to offer since some of them (especially the new ones) are super useful. Pixie-Dust Crown for Supporters** Added a dynamic, spinning, bobbing particle crown that renders above the heads of mod supporters. Uses a custom Pixie Dust particle system featuring a dense, short-lived, shimmering effect.Emits a subtle sparkling sound and includes 5 different themes (Gold, Crimson, Lavender, Ice, Emerald) by manipulating the HSB color values of a single grayscale texture at runtime. Automatically hides in first-person view to prevent visual obstruction. Powered by a remote manager that pulls configuration data asynchronously from GitHub and caches it for offline use. You will need to briefly connect to the Internet while launching Minecraft at least once to verify your ownership of the Crown. After that you can play offline and still see it! Configurable Aesthetics** Added a new Supporter Perks config group.Added a global toggle to disable rendering of all crowns if you hate fun. Added a global toggle to disable sound effects of all crowns. Added a local toggle to allow rendering your own crown in first-person mode if you want to both obstruct your view and thrill yourself. Added sliders for sound volume, particle count, crown radius, crown height, crown thickness, and vertical offset. Added a new "Toggle Supporter Crown" keybind allowing users to show/hide their own crown from both themselves and the rest of the server. A single press cycles the crown to the next available color theme, while a double-tap toggles the crown's visibility. Supporters can pick their own crown color. Your preference syncs instantly to all other players looking at you utilizing DataTracker networking.
### Changed
- Location-Centric Spawning Overhaul**
- Completely rewrote the world generation spawning logic. Instead of mapping individual hamster colors to biomes, biomes are now grouped into 9 "Spawning Environments" (e.g., Icy, Sandy, Forest, etc.)
- Each environment rolls against weighted hamster color groups. This ensures that whether a texture is procedurally generated or community-made, it mathematically evaluates its own color and automatically spawns in a biologically appropriate location.
- Diamond Sniffing Visuals & Audio**
- Added directional animations to indicate whether a buried diamond ore is above or below the hamster when it's sniffing for one and the path is obstructed.
- Added a dynamic "quick bounce" animation that intermittently triggers when the diamond ore is hidden somewhere above the hamster.
- Added a new head-shake sound effect that plays when the hamster is sniffing for ore and gets confused.
- Sweet Potato Easter Egg**
- The "Sweet Potato" Easter egg now applies a unique custom texture to the hamster, thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com)!
- Renaming a hamster "Sweet Potato" hides its normal genetics (base coat, overlays, and eye color) without permanently deleting them.
- Sweet Potato hamsters can still breed, and their offspring will genetically inherit traits mathematically blended from the sweet potato's unique color palette, but they do not spawn in the wild.
- Jade HUD Config Settings**
- Added a new "Jade Overlay Settings" section to the config under "UI & Quality of Life".
- Displays complex genetic info (Age, Base Coat, Wild Overlay, Breeding Overlay, Eye Color) by default.
- Added a "Require Sneaking" toggle (disabled by default) allowing you to hide the genetic overlay unless you are actively sneaking.
- Added individual toggles for every piece of my custom genetic info shown in the Jade overlay.
- Added additional toggles for selectively disabling default Jade info lines (Name, Health, Growth Time, Owner, Inventory) specifically for hamsters without impacting other entities, and a toggle to link their visibility to the player's sneaking state, allowing you to completely customize the HUD to your liking.
- Built a smart-formatting engine so that community texture IDs are automatically converted into localized, human-readable titles on the HUD (e.g.,
cheesecake_mocha.png -> "Cheesecake Mocha").Statue Performance & AI Toggling** Hamsters spawned with their AI disabled will now completely freeze their animation playback and no longer emit ambient idle squeaks. This attempts to reduce client-side rendering lag when hundreds of thousands of hamsters are on screen for testing, but Java itself struggles with that many cubes on screen, so it's still laggy if you try to look at 2 million+ hamsters simultaneously. You can now tame an AI-disabled hamster, which will instantly "wake it up" and turn it into a real, fully functional hamster. Added an Allow Taming to Re-Enable AI toggle to the config in case you're a server owner who wants to sell specific hamster breeds in a shop. If you have OP permissions on your server, you can turn this off to prevent players from taming and "waking up" frozen hamsters, allowing them to be used as shop displays or decorative statues.Mod Page/README** The README was functioning as a marketing poster, a technical manual, a credits roll, and a tutorial. That is too many jobs for one file. It was getting too large, so I have reorganized it, reworded it, and split a few things off into other easily accessible files, so the README only has one job now. Mount Priority** Changed default config value to HEAD_FIRST.Action Bar Config Toggles** Grouped all action bar message toggles (Shoulder Dismount, Tree Heist Start, Bed Break, Tamed Baby Warning, and Display Duration) into a new "Action Bar Messages" sub-category under "UI & Quality of Life" for easier access. Guidebook** Updated Hamster Bed entry to explicitly mention the Totem of Undying requirement for respawning. Guidebook Effects** If you obtain the Hamster Tips guidebook while viewing a chest or crafting screen, the "rediscovered" visual and audio effects will now be postponed until you close the screen, ensuring the effects do not play while you're looking at your inventory. If you keep the screen open for longer than 5 seconds after obtaining the book, the effects are silently cancelled. Cucumber Rebalance** Sliced Cucumbers are no longer inexplicably nutritious. Their default food value has been dropped from 2 hearts to 0.5 hearts to match items like Dried Kelp. Hamster Hitbox Adjustment** Shrunk the physical hitbox of hamsters by 15% to more accurately match their actual visual model size. Note: Because the bounding box is now smaller, you will need to aim slightly more accurately when trying to interact with a hamster.* Patchouli Version** Updated the internal guidebook generation logic to accommodate API breaking changes introduced in Patchouli version 1.21.1-93.You must update Patchouli to the latest version or the game will not launch. Shoulder Animation Configs** Replaced the single Forced Animation State setting with three distinct settings. You can now independently force the Head, Left Shoulder, and Right Shoulder hamsters into specific animation loops (when dynamic animations are disabled).Tree Heist Exits** Hamsters will now perform a small outward jump, launching themselves away from the tree upon successfully completing a Tree Heist. Breeding Cooldown Config** The config setting for breeding cooldown has been changed from Ticks to Seconds to make it significantly easier to manage with the slider.
### Fixed
- Config Live Changes**
- Fixed an issue where changing settings in the
World Gen & Loot config (such as wild bush or hamster spawning settings) required a full game restart to take effect. Saving changes to any config now recalibrates the mod's logic caches on both the client and the server.Visual Rotation Glitch** Attempted to fix an issue where using teleportation mods (like Waystones) or interrupting animations could cause the hamster's model to become permanently rotated backwards or upside down on the client side. I can't be 100% certain about this fix yet, because no one has been able to figure out exactly what causes it and I can't re-create it myself, so let me know if you run into it. Hamster Stretching with Shaders** Fixed a visual bug where hamsters would stretch to extreme sizes during multiplayer server lag or when pausing the game. Dismount Bug** Fixed an issue where holding down the Sneak key for more than a second would cause the OS's auto-key-repeat feature to spam the game with inputs, dismounting all of your shoulder hamsters rapidly. You can now safely hold Sneak without losing your friends. This bug has existed ever since the double-tap setting was added, but I hadn't found it because I usually play with Sneak set to "Toggle" (which means I have no reason to hold it down for extended periods). Memory Optimization** Implemented pre-caching for texture identifiers and simplified rotation math in the render loop to eliminate extra memory objects being generated every frame. Spanish Localization** Some strings in the Hamster Tips guidebook were still outdated (i.e., the Accessories and Sunflower pages). Malformed Recipe** The sliced_cucumber_from_cutting_board.json` recipe for compatibility with Farmers Delight failed to load on 1.20.1 due to a typo.

# **The Procedural Genetics Update**
Hamsters now utilize a fully procedural and configurable genetics engine with **3,158** new wild variants, **2,285,046** potential breeding outcomes, recessive red eyes, 13 new advancements, and a guidebook update that explains everything. Added comprehensive breeding settings to balance obsessions with server tick speed (looking at you, Janet). Also many bugs were squashed, and hamsters learned to play tag and spit out gifts from their cheeks. Make sure you update Patchouli to the latest version or your game won't launch!

### Added
- Procedural Genetics & Texture System**
- Procedural Genetics Engine**
- Hamsters are no longer pre-defined, hardcoded variants. Every hamster now possesses a fully serialized
detailing its precise genetic makeup across six distinct traits.This was accomplished by developing a 3D Hue/Saturation/Brightness (HSB) Cartesian color space. The mod uses this to mathematically map the exact color coordinates of every hamster variant into a three-dimensional neural network, which is dynamically used to calculate genetic relationships, mutations, overlay exclusion rules, and environment-spawning rules on the fly. I got the idea for creating the textures programmatically like this because that's how I made the original textures in Photoshop— using various Gradient Maps applied to a single, grayscale texture. Then I realized Java code can do the same thing! The total number of unique hamster types that spawn in the wild is now **3,231** by default, and the number of genetically inheritable hamster permutations from breeding is now **over 2.2 Million**. Want to understand the math?** Keep reading below— look for the _"Advanced Spawning & Testing Commands"_ section. I have added all sorts of fancy commands and tools to walk you through the breeding system in a way that is (hopefully) easy to understand. Dynamic Palette Swapping** Built an optimized, client-side dynamic texture generator. Instead of bloating your hard drive with over 2 million distinct PNG files, the mod dynamically recolors grayscale fur templates at runtime using custom genetic palette hex code data I designed based off my Photoshop workflow, then mixes them with hard-coded PNGs from the community. I realized the original hamster variants were just gradient maps applied to a grayscale texture in Photoshop. So, naturally, I invested an unreasonable amount of effort rebuilding Photoshop's Gradient Map tool inside Java. Does this save file space? Sort of, though tiny PNGs don't take up much space anyway. But it makes the system infinitely scalable. If I add just one new grayscale pattern or community-made texture in the future, the Java math will automatically multiply it across every single other variant in the game. For now, consider it an over-engineered proof of concept. Community Hamster Textures** Developed a parallel pipeline that automatically scans, analyzes, and genetically categorizes static, community-made PNG textures directly from the mod's JAR file. These static textures are seamlessly integrated into the procedural breeding pool alongside my programmatic colors. The rendering engine can automatically composite custom community textures into overlay masks. This means hamsters can spawn with community-made palettes serving as the color for their overlay spots and splotches! Thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com), we have 18 brand-new base hamster variants spawning in the wild! (Including *Cheesecake Mocha, Blue Fawn, Pearl Rose, Sable,* and 14 more). You can see them all in-game using the new spawn commands (see below). Expanded Overlays** Overlays are no longer just white. Wild Overlays:** Naturally spawning hamsters can now have overlays in any color that is closely related to White, Cream, or Gray, with a few configurable exceptions. To keep things looking natural, the default config ensures wild overlays are always brighter & less saturated than the base coat, Cream is disallowed on a Lavender or Blue base coat, and cave-spawned hamsters can only receive Gray overlays to help them blend in. Breeding Overlays:** A completely new secondary overlay layer, unlocked exclusively through breeding (45% chance when two first-generation wild hamsters breed). These are chosen based on the midpoint between the parents' base color in the 3D color-space coordinate system, with a bit of jitter so the baby won't always look the same when you breed two parents repeatedly, so the possibilities are nearly endless. These overlays will mathematically avoid copying the same shape/pattern as the wild overlay, to ensure they are not hidden/covered up by it. Breeding & Lifecycle Mechanics** Breeding Inheritance and Visualization Tool** Here's how it works:** When breeding two hamsters together, the color for the baby (and its overlay colors) are chosen based on a connected line between the two parents in the 3D color-space coordinate system. This means babies will tend towards the mathematical center, but occasionally one parent's color traits will strongly dominate the outcome, mimicking real-world genetics and providing visual variety within a single hamster family even if you breed the same two parents together repeatedly. Outcome Visualizer:** You can right-click two hamsters inside the 3D variants layout ( /ahp spawn_all_bases_3D) with the Hamster Tips guidebook to visualize the genetic probability distribution for their offspring via a cloud of Wax On particles. The particle spawning logic uses the exact same probability math that is used when creating babies, so it gives you a perfectly accurate representation of potential outcomes.Config Settings and Real-time Controls** Genetic Variance**: Adjusts how much a baby's base color can deviate from the exact center between its parents. Think of this as the "length" of the line between the parents. Genetic Mutation Rate**: Adjusts the random color scatter/mutations applied to babies. Think of this as the "thickness" of the line. Simulated Offspring Per Second**: Adjust the density of the 3D visualizer particle cloud. Each particle represents a potential baby. Real-time Controls:** While holding the guidebook, you can dynamically tweak the shape of the genetic probability cloud using the arrow keys: Left/Right Arrows adjust Genetic Variance; Up/Down Arrows adjust Genetic Mutation Rate. Server and Client Sync:** Since the particle visualizer is driven by the literal server-side breeding math, which is driven by the config for your server, and the changes you make with the arrow keys directly alter that config, the changes will take effect immediately for any future babies. Recessive Eye Genetics** Hamsters now possess dominant (Black) and recessive (Red) eye genetics. Red eyes do not exist in the wild. They are genetically tied to the "diluteness" (brightness/saturation) of the hamster's coat. A fully dilute hamster has up to a 50% chance of spawning with a recessive red eye gene. By selectively breeding highly dilute hamsters, players can uncover carriers ( Br) and eventually breed Red-Eyed (rr) variants. Uses punnet squares.Baby Growth Mechanics** You can now feed baby hamsters standard hamster food items to accelerate their growth. To balance this with their natural pickiness, a new config option ( Disable Baby Food Refusal) allows you to bypass their desire for dietary variety specifically for babies if you want. This is turned off by default, so to bypass their pickiness you'll need lots of **Hamster Food Mix** if you want to quickly grow them up.Feeding baby hamsters visually and mechanically accelerates their growth in smooth, continuous increments, similar to vanilla horses. Their "extra big head" proportions scale dynamically as they grow. Breeding Limitations** Added comprehensive config settings to manage hamster breeding for server owners who want to keep the population under control. Added a global Enable Breeding toggle (on by default) to instantly shut down all romance.Added a configurable Max Breeding Cycles limit per hamster to stop them from infinitely multiplying (off by default).Added a Limit Breeding By Player toggle. (also off by default). Limits can be assigned per-player based on Minecraft days or Real Life days, or simply capped as a lifetime maximum limit. Includes feedback to explain what's happening when attempting to over-feed beyond the limit.Added a /ahp reset_player_breeding_history command for server operators to reset their own breeding history.Added a /ahp reset_hamster_breeding_history command for server operators to reset a specific hamster's timesBred quota to zero.Added a convenient "Reset Breeding History" button in the Config screen that executes the command for the user (requires OP permissions). Configurable Litter Size** Added to config sliders allowing you to set the minimum and maximum litter size when hamsters get into hanky-panky. The final size of the litter will be a random number between the min and max. Breeder Whitelist** Added a config list allowing specific players to bypass the global breeding ban. In case your server needs a designated rodent baron. Post-Breeding Animation** Hamsters will now crouch down and lovingly inspect their baby(s) after the litter is born, spawn heart particles, and make affectionate sounds shortly after successfully contributing to your growing population problem. Wild Baby Configuration** Added Babies Spawn Wild setting. When enabled, babies are born feral and do not inherit their parent's ownership status, letting multiplayer groups decide who claims them.When untamed, babies no longer flee from players, making them easier to manage. Parent-Following** Babies will now randomly select a parent to follow until adulthood, instead of following their owner. Wild baby hamsters will switch to following the player if their parent is currently mounted on the player's shoulder. They will automatically resume following the parent once it is dismounted. If you want the baby to follow you instead, you must first tame it, then you can break its connection to the parent by right-clicking it with a Lure Item (Cheese by default). Added a config toggle to disable the action bar message that warns you when a newly tamed baby hamster refuses to follow you because it's still attached to its parent. Age Tracking** Hamsters now track their absolute lifetime age in ticks. Wild hamsters spawn with a random age between 1 and 30 days. Added /ahp set_age command to manually override a hamster's age (since older hamsters will start at 0 days old upon updating to this version of the mod). It accepts units (days, months, years) and provides autocomplete suggestions.If you do not specify a target, it will automatically apply to the hamster you are currently looking at. The Jade HUD overlay displays the hamster's age alongside its genetic data. Added a new Display IRL Age config setting that dictates how fast the hamster ages. If true, their age progresses at 1/72nd the normal speed (matching the real-world 24-hour cycle).Performance Improvements** Significant Overall Improvements** Flattened the entire visual render layer stack (base coat, wild overlays, breeding overlays, skin, eyes, armor, and accessories) into a single, dynamically composited texture at runtime. This completely eliminates all secondary GeoRenderLayer passes. Every hamster, regardless of its complex genetics or equipped items, now costs exactly one draw call to render (previously it was anywhere from 2 to 8!), resulting in a massive performance boost. Especially noticeable when numerous hamsters are on screen at the same time.Bare-Bones Ultra Performance Mode** Added a new Performance Mode toggle in the config (and an assignable keybind) designed specifically for viewing absurd numbers of hamsters simultaneously without melting your GPU.When enabled, it bypasses the dynamic texture engine entirely (falling back to a single flat texture) and hides almost all the model's geometry. The hamsters essentially become grayscale cubes, stripping away nearly all matrix-calculation overhead. The Jade HUD overlay will still display their exact genetic information, because the server never forgets what they are actually supposed to look like. New Config Settings** Wild Overlay Configurability** Added new Allowed Wild Overlay Zones list to the World Gen & Loot config. This allows server owners/modpack makers to explicitly control which color zones the genetics engine is allowed to use when picking an overlay for a naturally spawning hamster. Defaults to natural colors (WHITE, LIGHT_GRAY, DARK_GRAY, and CREAM).Added new Restricted Base Colors and Clashing Overlay Colors lists. By default, these prevent CREAM and DARK_GRAY wild overlays from spawning on top of BLUE and LAVENDER base coats, as these color combinations tend to look a bit strange visually.Added new Enforce Brighter Overlays and Enforce Muted Overlays toggles. Allows players to disable the overlay filtering that prevents saturated colors (like Cream) from spawning on muted bases (like Black) and darker colors from being used as overlays on top of lighter bases.Modifying the overlay settings can dramatically change the number of possible combinations for wild hamsters (3,231 by default). Red Eye Config Toggle** Don't like the red eye hamsters? You can visually disable that for your own client via a new config toggle, which makes them appear to have black eyes. Friendly Fire Config Toggle** Added Prevent Owner Friendly Fire to the Core config toggles.When enabled, players can no longer accidentally damage their own tamed hamsters. Disabled by default to remain vanilla-friendly. In the next update (hopefully), this setting will be tied to a new item: the **Acorn Ring**. I also plan to integrate with the **Trinkets** mod so you can use a trinket slot for it. Configurable Cuisine** You can now configure the nutrition and saturation values for all food items added by the mod (Cucumbers, Green Beans, Food Mix). Changed nutrition/saturation values are dynamically reflected in AppleSkin's "on-eat" HUD preview. **Unfortunately due to major API changes between MC versions, this only works on 1.21.1.* Max Mounted Hamsters Config** Added a configuration slider under 'Shoulder Hamster Settings > Core Settings' allowing players to limit the maximum number of hamsters that can be mounted simultaneously (1 to 3). Gameplay Mechanics & Interactions** Tag Mini-Game** Hamsters can now initiate a playful game of tag. If you maintain eye contact with a hamster for a few seconds, it will squeak and excitedly run away. The Chase:** The hamster will flee if you get too close and stop to playfully taunt you if you fall too far behind. Payoff:** Successfully "catching" (right-clicking) the hamster before it gets bored ends the game triggers a celebration. The hamster will then spit out a random item from its cheek pouches as a gift (pulling from the configurable cheek pouch loot lists). Stranger Danger:** By default, you can play tag with wild hamsters and hamsters owned by other players. (Can be disabled in config). Configurable Limits and Rewards** Added configs to control how often they want to play, the cooldown between games, and an anti-abuse cap on how many times a single player can play the game per in-game day (so they can't farm rewards). Added configs to control rewards: By default, hamsters will randomly pick an item from their configurable "Cheek Pouch Loot" list (the list of potential items a wild hamster might spawn with). The item does not have to be in the hamster's cheek pouch for it to give it as a gift. That can be disabled, in which case the hamster will choose the gift from a separate "Custom Tag Rewards" list in the config, which means you can make your hamster give you a diamond or any modded item (or whatever you want) when you catch it after a game of tag. Only server moderators can modify this of course. Dynamic Gaze** Hamsters will now sustain eye contact with you indefinitely, provided you are nearby and continue looking back at them, and of course as long as they don't start a game of tag. Hamster Yeet Overhaul** Thrown hamsters are now officially registered as ProjectileEntity instances while airborne. This provides automatic, out-of-the-box compatibility with external mods that use targets or hoops (such as the Tin Hoops in Caverns and Chasms).Thrown hamsters now experience dynamic physics upon impact. They will ricochet backward off of walls and entities, or skip forward when hitting floors and ceilings. Thrown hamsters now dynamically query and broadcast the native sound of the block or entity they strike (including modded blocks/entities). Impact physics are magnified when hitting Slime blocks, and completely absorbed by Honey blocks. Added a new config toggle (true by default) allowing thrown hamsters to damage their owner. Throwing your own rodent straight up in the air will now result in a realistic, concussive reunion on the way back down. Precision Tree Heists** Right-clicking Oak Leaves with a lure item (Cheese) while a hamster is on your shoulder will now initiate a "Precision Tree Heist." This sets that specific leaf block as the guaranteed exit point for the hamster. While a precision heist is active, right-clicking in the air with the lure item will set the hamster's exit direction to match the direction you are currently looking. Why?** This allows you to precisely control the exact block and angle by which your hamster will exit the tree, which makes for much more predictable recording sessions. Moonwalking Easter Egg** Name your hamster "Michael Jackson" or "Steve Irwin" and it will rotate backwards and remain that way until you change the name again. Expanded Default Diet** Hamsters can now eat seeds from almost any mod out-of-the-box. Added a robust union tag to the default config that automatically syncs with #c:seeds and #forge:seeds to ensure compatibility across all versions and mod loaders.Failsafes & Rescues** Teleport Rescue Protocol** Overhauled how hamsters follow you across vast distances or dimensions (e.g., when using Waystones). Instead of relying on their tiny legs and pathfinding AI to catch up, your player code will now safely scoop up any actively following hamsters (and their babies if the babies are following them), hold them in a little NBT pocket while the world loads, and drop them at your new location 0.75 seconds later. Void Rescue Protocol** If a player falls into the void and dies with hamsters on their shoulders, the hamsters will no longer spawn in the void and immediately perish. The system will safely teleport them back to their linked bed. If they do not have a linked bed, they will be sent to the player's personal respawn point or the world spawn. UI, HUD, & Audio** Jade Integration** Added comprehensive Jade overlay integration that reveals a hamster's exact genetic makeup (base coat, wild overlay, breeding overlay, eye genotype, etc.) when you look at them. Enabled without needing to turn on debug mode to help with breeding. Fully customizable. Each setting comes with its own toggle, and you can decide which ones show up when you sneak to keep the Jade HUD de-cluttered. GUI Renaming System** Players can now rename their hamsters directly from the Hamster Inventory screen. Features dynamic down-scaling to ensure long names always fit perfectly within the UI constraints. An interactive pencil icon and underline display when hovering/typing. New Config Options ( UI & Quality of Life > Hamster Renaming)**Enable GUI Renaming: Master toggle for the feature.Consume Name Tag: Forces players to sacrifice a Name Tag from their inventory (or the hamster's cheeks) to finalize the rename.Pencil Icon Placement: Allows swapping the icon to the left or right of the text for those who read in different directions.New Audio & Visuals** Added a brand new anim_hamster_cheek_unload animation used for gifting items, complete with item and spit particle effects.Added 4 new scratching sound variations for the cleaning animation, and switched to keyframes for the SFX to make it less repetitive and more realistic. This also has the side effect of muting the sound effect if the hamster is not on screen, and thus not being rendered. This means you will no longer hear nearby hamsters cleaning unless you can also see them. Added dynamic item sounds (clink, squish, thud, etc.) to the new gifting sequence. Commands & Admin Tools** Advanced Spawning & Testing Commands** Added /ahp spawn hamster <basePalette> <wildPattern> <wildPalette> <breedPattern> <breedPalette> <eyes>. This command features a custom Brigadier auto-complete engine that suggests exact, human-readable palette and pattern names as you type, allowing you to easily test specific genetic combinations.Added /ahp spawn_all_bases_2D. Systematically lines up every single hamster color base in the game (including custom community additions), sorted cleanly into rows by their dynamically determined, mathematical color zone.Added /ahp spawn_all_bases_3D. Spawns the hamsters hovering in a physical 3D "cylinder" representing their Hue/Saturation/Brightness coordinates. This is useful for the **Breeding Inheritance and Visualization Tool** (see below).Hue** = the degree of the circle (0-360) Saturation** = the radius of the circle (more saturated colors are closer to the edge) Brightness** = the height of the cylinder (brighter hamsters are closer to the top) By default, each /ahp spawn_all_bases... command spawns just the 45 base colors, but each one comes with 3 optional arguments to change the number of hamsters spawned: 1. [with_wild_overlays] Displays all 3,231 hamster variants that can spawn naturally in the wild.
2. [with_sample_breeding_overlays] Displays genetic combinations of every wild hamster but adds in a small sample of three breeding overlays (Tortoise Shell, Silver, and Rust). Due to the triple-multiplication math involved, this heavily increases the total number of hamsters spawned (from 3,231 up to 9,693) creating a much bigger display.
3. [author] only uses color palletes from a certain author (e.g., jimcerberus or default).
- Added
/ahp spawn_all_possible_permutations_THIS_CAN_BREAK_YOUR_WORLD. Exactly what it sounds like. Don't run it unless you have a super-flat world, a fire extinguisher for your PC, and a lot of patience. Note that every time I have run this command, my server tick speed never quite returned to baseline— even after deleting all the hamsters that were spawned using /kill @e[type=!player].Added /ahp print_genetics_report command, allowing server operators to recalculate and view the current 3D color-space math of the genetics engine at runtime. Useful because it dynamically updates its readout based on your exact AhpWorldGenConfig wild overlay settings, so you can see how your changes are affecting the total possible variant numbers without having to spawn them all.Tree Heist History Command** Added /ahp reset_tree_economy for quick clearing of tree depletion memory without needing to open the config screen.Advancements** Advancement: Carat Confusion** Triggers when a hamster leads you to Gold Ore instead of Diamond. Advancement: Load-Bearing Human** Triggers when you mount 3 hamsters simultaneously (Right, Left, Head). Genetic Progression Advancements** Added "The Collector" advancement path tracking unique wild variants tamed (up to dynamic maximum based on configuration limits). Added "The Breeder" advancement path tracking unique bred combinations (up to 1,000,000). Added a conditional advancement "Seeing Red" for successfully breeding the recessive eye trait. Does not trigger if red eyes have been turned off in the config. Implemented high-performance, non-bloating NBT storage using IntArrays to track thousands of HamsterGenome hashes without lagging the player entity.Guidebook Enhancements** Guidebook Delivery Fallback** Added a new configuration option that acts as a fallback for modpacks that disable auto-guidebook delivery on login. If enabled (default), players will automatically be given the Hamster Tips guidebook and receive a chat prompt the very first time they spot a wild hamster from <=10 blocks away. Targeting calculation includes wiggle room to ensure the event triggers even if the player's crosshair isn't perfectly on the hamster's hit box. Only triggers once, and only if the player has never yet received the guidebook (regardless of current inventory status). Lectern Reading** Added code for placing the Hamster Tips guide book into a lectern and an event handler so you can read it. You can now display your rodent knowledge in your base or wherever. Hamster Tips Guidebook Improvements** The *Hamster Tips* guidebook now uses a custom string processor to pull live data directly into the text, so I can do things like automatically displaying the exact number of mathematically possible wild variants or the name of your dynamically configured Lure Item instead of hardcoding "Cheese". Updated the "Regional Rodents" entry to explain the new biome-adaptive color logic, Wild Overlays and Jade integration. Added a new "Breeding" entry in _The Hamster Life_ chapter detailing the genetic mechanics, recessive red eyes, and feral youth mechanics. Added a new "Admin Commands" entry in _The Kitchen Drawer_ chapter detailing the various new (and old) commands the mod has to offer since some of them (especially the new ones) are super useful. Pixie-Dust Crown for Supporters** Added a dynamic, spinning, bobbing particle crown that renders above the heads of mod supporters. Uses a custom Pixie Dust particle system featuring a dense, short-lived, shimmering effect.Emits a subtle sparkling sound and includes 5 different themes (Gold, Crimson, Lavender, Ice, Emerald) by manipulating the HSB color values of a single grayscale texture at runtime. Automatically hides in first-person view to prevent visual obstruction. Powered by a remote manager that pulls configuration data asynchronously from GitHub and caches it for offline use. You will need to briefly connect to the Internet while launching Minecraft at least once to verify your ownership of the Crown. After that you can play offline and still see it! Configurable Aesthetics** Added a new Supporter Perks config group.Added a global toggle to disable rendering of all crowns if you hate fun. Added a global toggle to disable sound effects of all crowns. Added a local toggle to allow rendering your own crown in first-person mode if you want to both obstruct your view and thrill yourself. Added sliders for sound volume, particle count, crown radius, crown height, crown thickness, and vertical offset. Added a new "Toggle Supporter Crown" keybind allowing users to show/hide their own crown from both themselves and the rest of the server. A single press cycles the crown to the next available color theme, while a double-tap toggles the crown's visibility. Supporters can pick their own crown color. Your preference syncs instantly to all other players looking at you utilizing DataTracker networking.
### Changed
- Location-Centric Spawning Overhaul**
- Completely rewrote the world generation spawning logic. Instead of mapping individual hamster colors to biomes, biomes are now grouped into 9 "Spawning Environments" (e.g., Icy, Sandy, Forest, etc.)
- Each environment rolls against weighted hamster color groups. This ensures that whether a texture is procedurally generated or community-made, it mathematically evaluates its own color and automatically spawns in a biologically appropriate location.
- Diamond Sniffing Visuals & Audio**
- Added directional animations to indicate whether a buried diamond ore is above or below the hamster when it's sniffing for one and the path is obstructed.
- Added a dynamic "quick bounce" animation that intermittently triggers when the diamond ore is hidden somewhere above the hamster.
- Added a new head-shake sound effect that plays when the hamster is sniffing for ore and gets confused.
- Sweet Potato Easter Egg**
- The "Sweet Potato" Easter egg now applies a unique custom texture to the hamster, thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com)!
- Renaming a hamster "Sweet Potato" hides its normal genetics (base coat, overlays, and eye color) without permanently deleting them.
- Sweet Potato hamsters can still breed, and their offspring will genetically inherit traits mathematically blended from the sweet potato's unique color palette, but they do not spawn in the wild.
- Jade HUD Config Settings**
- Added a new "Jade Overlay Settings" section to the config under "UI & Quality of Life".
- Displays complex genetic info (Age, Base Coat, Wild Overlay, Breeding Overlay, Eye Color) by default.
- Added a "Require Sneaking" toggle (disabled by default) allowing you to hide the genetic overlay unless you are actively sneaking.
- Added individual toggles for every piece of my custom genetic info shown in the Jade overlay.
- Added additional toggles for selectively disabling default Jade info lines (Name, Health, Growth Time, Owner, Inventory) specifically for hamsters without impacting other entities, and a toggle to link their visibility to the player's sneaking state, allowing you to completely customize the HUD to your liking.
- Built a smart-formatting engine so that community texture IDs are automatically converted into localized, human-readable titles on the HUD (e.g.,
cheesecake_mocha.png -> "Cheesecake Mocha").Statue Performance & AI Toggling** Hamsters spawned with their AI disabled will now completely freeze their animation playback and no longer emit ambient idle squeaks. This attempts to reduce client-side rendering lag when hundreds of thousands of hamsters are on screen for testing, but Java itself struggles with that many cubes on screen, so it's still laggy if you try to look at 2 million+ hamsters simultaneously. You can now tame an AI-disabled hamster, which will instantly "wake it up" and turn it into a real, fully functional hamster. Added an Allow Taming to Re-Enable AI toggle to the config in case you're a server owner who wants to sell specific hamster breeds in a shop. If you have OP permissions on your server, you can turn this off to prevent players from taming and "waking up" frozen hamsters, allowing them to be used as shop displays or decorative statues.Mod Page/README** The README was functioning as a marketing poster, a technical manual, a credits roll, and a tutorial. That is too many jobs for one file. It was getting too large, so I have reorganized it, reworded it, and split a few things off into other easily accessible files, so the README only has one job now. Mount Priority** Changed default config value to HEAD_FIRST.Action Bar Config Toggles** Grouped all action bar message toggles (Shoulder Dismount, Tree Heist Start, Bed Break, Tamed Baby Warning, and Display Duration) into a new "Action Bar Messages" sub-category under "UI & Quality of Life" for easier access. Guidebook** Updated Hamster Bed entry to explicitly mention the Totem of Undying requirement for respawning. Guidebook Effects** If you obtain the Hamster Tips guidebook while viewing a chest or crafting screen, the "rediscovered" visual and audio effects will now be postponed until you close the screen, ensuring the effects do not play while you're looking at your inventory. If you keep the screen open for longer than 5 seconds after obtaining the book, the effects are silently cancelled. Cucumber Rebalance** Sliced Cucumbers are no longer inexplicably nutritious. Their default food value has been dropped from 2 hearts to 0.5 hearts to match items like Dried Kelp. Hamster Hitbox Adjustment** Shrunk the physical hitbox of hamsters by 15% to more accurately match their actual visual model size. Note: Because the bounding box is now smaller, you will need to aim slightly more accurately when trying to interact with a hamster.* Patchouli Version** Updated the internal guidebook generation logic to accommodate API breaking changes introduced in Patchouli version 1.21.1-93.You must update Patchouli to the latest version or the game will not launch. Shoulder Animation Configs** Replaced the single Forced Animation State setting with three distinct settings. You can now independently force the Head, Left Shoulder, and Right Shoulder hamsters into specific animation loops (when dynamic animations are disabled).Tree Heist Exits** Hamsters will now perform a small outward jump, launching themselves away from the tree upon successfully completing a Tree Heist. Breeding Cooldown Config** The config setting for breeding cooldown has been changed from Ticks to Seconds to make it significantly easier to manage with the slider.
### Fixed
- Config Live Changes**
- Fixed an issue where changing settings in the
World Gen & Loot config (such as wild bush or hamster spawning settings) required a full game restart to take effect. Saving changes to any config now recalibrates the mod's logic caches on both the client and the server.Visual Rotation Glitch** Attempted to fix an issue where using teleportation mods (like Waystones) or interrupting animations could cause the hamster's model to become permanently rotated backwards or upside down on the client side. I can't be 100% certain about this fix yet, because no one has been able to figure out exactly what causes it and I can't re-create it myself, so let me know if you run into it. Hamster Stretching with Shaders** Fixed a visual bug where hamsters would stretch to extreme sizes during multiplayer server lag or when pausing the game. Dismount Bug** Fixed an issue where holding down the Sneak key for more than a second would cause the OS's auto-key-repeat feature to spam the game with inputs, dismounting all of your shoulder hamsters rapidly. You can now safely hold Sneak without losing your friends. This bug has existed ever since the double-tap setting was added, but I hadn't found it because I usually play with Sneak set to "Toggle" (which means I have no reason to hold it down for extended periods). Memory Optimization** Implemented pre-caching for texture identifiers and simplified rotation math in the render loop to eliminate extra memory objects being generated every frame. Spanish Localization** Some strings in the Hamster Tips guidebook were still outdated (i.e., the Accessories and Sunflower pages). Malformed Recipe** The sliced_cucumber_from_cutting_board.json` recipe for compatibility with Farmers Delight failed to load on 1.20.1 due to a typo.

# **The Procedural Genetics Update**
Hamsters now utilize a fully procedural and configurable genetics engine with **3,158** new wild variants, **2,285,046** potential breeding outcomes, recessive red eyes, 13 new advancements, and a guidebook update that explains everything. Added comprehensive breeding settings to balance obsessions with server tick speed (looking at you, Janet). Also many bugs were squashed, and hamsters learned to play tag and spit out gifts from their cheeks. Make sure you update Patchouli to the latest version or your game won't launch!

### Added
- Procedural Genetics & Texture System**
- Procedural Genetics Engine**
- Hamsters are no longer pre-defined, hardcoded variants. Every hamster now possesses a fully serialized
detailing its precise genetic makeup across six distinct traits.This was accomplished by developing a 3D Hue/Saturation/Brightness (HSB) Cartesian color space. The mod uses this to mathematically map the exact color coordinates of every hamster variant into a three-dimensional neural network, which is dynamically used to calculate genetic relationships, mutations, overlay exclusion rules, and environment-spawning rules on the fly. I got the idea for creating the textures programmatically like this because that's how I made the original textures in Photoshop— using various Gradient Maps applied to a single, grayscale texture. Then I realized Java code can do the same thing! The total number of unique hamster types that spawn in the wild is now **3,231** by default, and the number of genetically inheritable hamster permutations from breeding is now **over 2.2 Million**. Want to understand the math?** Keep reading below— look for the _"Advanced Spawning & Testing Commands"_ section. I have added all sorts of fancy commands and tools to walk you through the breeding system in a way that is (hopefully) easy to understand. Dynamic Palette Swapping** Built an optimized, client-side dynamic texture generator. Instead of bloating your hard drive with over 2 million distinct PNG files, the mod dynamically recolors grayscale fur templates at runtime using custom genetic palette hex code data I designed based off my Photoshop workflow, then mixes them with hard-coded PNGs from the community. I realized the original hamster variants were just gradient maps applied to a grayscale texture in Photoshop. So, naturally, I invested an unreasonable amount of effort rebuilding Photoshop's Gradient Map tool inside Java. Does this save file space? Sort of, though tiny PNGs don't take up much space anyway. But it makes the system infinitely scalable. If I add just one new grayscale pattern or community-made texture in the future, the Java math will automatically multiply it across every single other variant in the game. For now, consider it an over-engineered proof of concept. Community Hamster Textures** Developed a parallel pipeline that automatically scans, analyzes, and genetically categorizes static, community-made PNG textures directly from the mod's JAR file. These static textures are seamlessly integrated into the procedural breeding pool alongside my programmatic colors. The rendering engine can automatically composite custom community textures into overlay masks. This means hamsters can spawn with community-made palettes serving as the color for their overlay spots and splotches! Thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com), we have 18 brand-new base hamster variants spawning in the wild! (Including *Cheesecake Mocha, Blue Fawn, Pearl Rose, Sable,* and 14 more). You can see them all in-game using the new spawn commands (see below). Expanded Overlays** Overlays are no longer just white. Wild Overlays:** Naturally spawning hamsters can now have overlays in any color that is closely related to White, Cream, or Gray, with a few configurable exceptions. To keep things looking natural, the default config ensures wild overlays are always brighter & less saturated than the base coat, Cream is disallowed on a Lavender or Blue base coat, and cave-spawned hamsters can only receive Gray overlays to help them blend in. Breeding Overlays:** A completely new secondary overlay layer, unlocked exclusively through breeding (45% chance when two first-generation wild hamsters breed). These are chosen based on the midpoint between the parents' base color in the 3D color-space coordinate system, with a bit of jitter so the baby won't always look the same when you breed two parents repeatedly, so the possibilities are nearly endless. These overlays will mathematically avoid copying the same shape/pattern as the wild overlay, to ensure they are not hidden/covered up by it. Breeding & Lifecycle Mechanics** Breeding Inheritance and Visualization Tool** Here's how it works:** When breeding two hamsters together, the color for the baby (and its overlay colors) are chosen based on a connected line between the two parents in the 3D color-space coordinate system. This means babies will tend towards the mathematical center, but occasionally one parent's color traits will strongly dominate the outcome, mimicking real-world genetics and providing visual variety within a single hamster family even if you breed the same two parents together repeatedly. Outcome Visualizer:** You can right-click two hamsters inside the 3D variants layout ( /ahp spawn_all_bases_3D) with the Hamster Tips guidebook to visualize the genetic probability distribution for their offspring via a cloud of Wax On particles. The particle spawning logic uses the exact same probability math that is used when creating babies, so it gives you a perfectly accurate representation of potential outcomes.Config Settings and Real-time Controls** Genetic Variance**: Adjusts how much a baby's base color can deviate from the exact center between its parents. Think of this as the "length" of the line between the parents. Genetic Mutation Rate**: Adjusts the random color scatter/mutations applied to babies. Think of this as the "thickness" of the line. Simulated Offspring Per Second**: Adjust the density of the 3D visualizer particle cloud. Each particle represents a potential baby. Real-time Controls:** While holding the guidebook, you can dynamically tweak the shape of the genetic probability cloud using the arrow keys: Left/Right Arrows adjust Genetic Variance; Up/Down Arrows adjust Genetic Mutation Rate. Server and Client Sync:** Since the particle visualizer is driven by the literal server-side breeding math, which is driven by the config for your server, and the changes you make with the arrow keys directly alter that config, the changes will take effect immediately for any future babies. Recessive Eye Genetics** Hamsters now possess dominant (Black) and recessive (Red) eye genetics. Red eyes do not exist in the wild. They are genetically tied to the "diluteness" (brightness/saturation) of the hamster's coat. A fully dilute hamster has up to a 50% chance of spawning with a recessive red eye gene. By selectively breeding highly dilute hamsters, players can uncover carriers ( Br) and eventually breed Red-Eyed (rr) variants. Uses punnet squares.Baby Growth Mechanics** You can now feed baby hamsters standard hamster food items to accelerate their growth. To balance this with their natural pickiness, a new config option ( Disable Baby Food Refusal) allows you to bypass their desire for dietary variety specifically for babies if you want. This is turned off by default, so to bypass their pickiness you'll need lots of **Hamster Food Mix** if you want to quickly grow them up.Feeding baby hamsters visually and mechanically accelerates their growth in smooth, continuous increments, similar to vanilla horses. Their "extra big head" proportions scale dynamically as they grow. Breeding Limitations** Added comprehensive config settings to manage hamster breeding for server owners who want to keep the population under control. Added a global Enable Breeding toggle (on by default) to instantly shut down all romance.Added a configurable Max Breeding Cycles limit per hamster to stop them from infinitely multiplying (off by default).Added a Limit Breeding By Player toggle. (also off by default). Limits can be assigned per-player based on Minecraft days or Real Life days, or simply capped as a lifetime maximum limit. Includes feedback to explain what's happening when attempting to over-feed beyond the limit.Added a /ahp reset_player_breeding_history command for server operators to reset their own breeding history.Added a /ahp reset_hamster_breeding_history command for server operators to reset a specific hamster's timesBred quota to zero.Added a convenient "Reset Breeding History" button in the Config screen that executes the command for the user (requires OP permissions). Configurable Litter Size** Added to config sliders allowing you to set the minimum and maximum litter size when hamsters get into hanky-panky. The final size of the litter will be a random number between the min and max. Breeder Whitelist** Added a config list allowing specific players to bypass the global breeding ban. In case your server needs a designated rodent baron. Post-Breeding Animation** Hamsters will now crouch down and lovingly inspect their baby(s) after the litter is born, spawn heart particles, and make affectionate sounds shortly after successfully contributing to your growing population problem. Wild Baby Configuration** Added Babies Spawn Wild setting. When enabled, babies are born feral and do not inherit their parent's ownership status, letting multiplayer groups decide who claims them.When untamed, babies no longer flee from players, making them easier to manage. Parent-Following** Babies will now randomly select a parent to follow until adulthood, instead of following their owner. Wild baby hamsters will switch to following the player if their parent is currently mounted on the player's shoulder. They will automatically resume following the parent once it is dismounted. If you want the baby to follow you instead, you must first tame it, then you can break its connection to the parent by right-clicking it with a Lure Item (Cheese by default). Added a config toggle to disable the action bar message that warns you when a newly tamed baby hamster refuses to follow you because it's still attached to its parent. Age Tracking** Hamsters now track their absolute lifetime age in ticks. Wild hamsters spawn with a random age between 1 and 30 days. Added /ahp set_age command to manually override a hamster's age (since older hamsters will start at 0 days old upon updating to this version of the mod). It accepts units (days, months, years) and provides autocomplete suggestions.If you do not specify a target, it will automatically apply to the hamster you are currently looking at. The Jade HUD overlay displays the hamster's age alongside its genetic data. Added a new Display IRL Age config setting that dictates how fast the hamster ages. If true, their age progresses at 1/72nd the normal speed (matching the real-world 24-hour cycle).Performance Improvements** Significant Overall Improvements** Flattened the entire visual render layer stack (base coat, wild overlays, breeding overlays, skin, eyes, armor, and accessories) into a single, dynamically composited texture at runtime. This completely eliminates all secondary GeoRenderLayer passes. Every hamster, regardless of its complex genetics or equipped items, now costs exactly one draw call to render (previously it was anywhere from 2 to 8!), resulting in a massive performance boost. Especially noticeable when numerous hamsters are on screen at the same time.Bare-Bones Ultra Performance Mode** Added a new Performance Mode toggle in the config (and an assignable keybind) designed specifically for viewing absurd numbers of hamsters simultaneously without melting your GPU.When enabled, it bypasses the dynamic texture engine entirely (falling back to a single flat texture) and hides almost all the model's geometry. The hamsters essentially become grayscale cubes, stripping away nearly all matrix-calculation overhead. The Jade HUD overlay will still display their exact genetic information, because the server never forgets what they are actually supposed to look like. New Config Settings** Wild Overlay Configurability** Added new Allowed Wild Overlay Zones list to the World Gen & Loot config. This allows server owners/modpack makers to explicitly control which color zones the genetics engine is allowed to use when picking an overlay for a naturally spawning hamster. Defaults to natural colors (WHITE, LIGHT_GRAY, DARK_GRAY, and CREAM).Added new Restricted Base Colors and Clashing Overlay Colors lists. By default, these prevent CREAM and DARK_GRAY wild overlays from spawning on top of BLUE and LAVENDER base coats, as these color combinations tend to look a bit strange visually.Added new Enforce Brighter Overlays and Enforce Muted Overlays toggles. Allows players to disable the overlay filtering that prevents saturated colors (like Cream) from spawning on muted bases (like Black) and darker colors from being used as overlays on top of lighter bases.Modifying the overlay settings can dramatically change the number of possible combinations for wild hamsters (3,231 by default). Red Eye Config Toggle** Don't like the red eye hamsters? You can visually disable that for your own client via a new config toggle, which makes them appear to have black eyes. Friendly Fire Config Toggle** Added Prevent Owner Friendly Fire to the Core config toggles.When enabled, players can no longer accidentally damage their own tamed hamsters. Disabled by default to remain vanilla-friendly. In the next update (hopefully), this setting will be tied to a new item: the **Acorn Ring**. I also plan to integrate with the **Trinkets** mod so you can use a trinket slot for it. Configurable Cuisine** You can now configure the nutrition and saturation values for all food items added by the mod (Cucumbers, Green Beans, Food Mix). Changed nutrition/saturation values are dynamically reflected in AppleSkin's "on-eat" HUD preview. **Unfortunately due to major API changes between MC versions, this only works on 1.21.1.* Max Mounted Hamsters Config** Added a configuration slider under 'Shoulder Hamster Settings > Core Settings' allowing players to limit the maximum number of hamsters that can be mounted simultaneously (1 to 3). Gameplay Mechanics & Interactions** Tag Mini-Game** Hamsters can now initiate a playful game of tag. If you maintain eye contact with a hamster for a few seconds, it will squeak and excitedly run away. The Chase:** The hamster will flee if you get too close and stop to playfully taunt you if you fall too far behind. Payoff:** Successfully "catching" (right-clicking) the hamster before it gets bored ends the game triggers a celebration. The hamster will then spit out a random item from its cheek pouches as a gift (pulling from the configurable cheek pouch loot lists). Stranger Danger:** By default, you can play tag with wild hamsters and hamsters owned by other players. (Can be disabled in config). Configurable Limits and Rewards** Added configs to control how often they want to play, the cooldown between games, and an anti-abuse cap on how many times a single player can play the game per in-game day (so they can't farm rewards). Added configs to control rewards: By default, hamsters will randomly pick an item from their configurable "Cheek Pouch Loot" list (the list of potential items a wild hamster might spawn with). The item does not have to be in the hamster's cheek pouch for it to give it as a gift. That can be disabled, in which case the hamster will choose the gift from a separate "Custom Tag Rewards" list in the config, which means you can make your hamster give you a diamond or any modded item (or whatever you want) when you catch it after a game of tag. Only server moderators can modify this of course. Dynamic Gaze** Hamsters will now sustain eye contact with you indefinitely, provided you are nearby and continue looking back at them, and of course as long as they don't start a game of tag. Hamster Yeet Overhaul** Thrown hamsters are now officially registered as ProjectileEntity instances while airborne. This provides automatic, out-of-the-box compatibility with external mods that use targets or hoops (such as the Tin Hoops in Caverns and Chasms).Thrown hamsters now experience dynamic physics upon impact. They will ricochet backward off of walls and entities, or skip forward when hitting floors and ceilings. Thrown hamsters now dynamically query and broadcast the native sound of the block or entity they strike (including modded blocks/entities). Impact physics are magnified when hitting Slime blocks, and completely absorbed by Honey blocks. Added a new config toggle (true by default) allowing thrown hamsters to damage their owner. Throwing your own rodent straight up in the air will now result in a realistic, concussive reunion on the way back down. Precision Tree Heists** Right-clicking Oak Leaves with a lure item (Cheese) while a hamster is on your shoulder will now initiate a "Precision Tree Heist." This sets that specific leaf block as the guaranteed exit point for the hamster. While a precision heist is active, right-clicking in the air with the lure item will set the hamster's exit direction to match the direction you are currently looking. Why?** This allows you to precisely control the exact block and angle by which your hamster will exit the tree, which makes for much more predictable recording sessions. Moonwalking Easter Egg** Name your hamster "Michael Jackson" or "Steve Irwin" and it will rotate backwards and remain that way until you change the name again. Expanded Default Diet** Hamsters can now eat seeds from almost any mod out-of-the-box. Added a robust union tag to the default config that automatically syncs with #c:seeds and #forge:seeds to ensure compatibility across all versions and mod loaders.Failsafes & Rescues** Teleport Rescue Protocol** Overhauled how hamsters follow you across vast distances or dimensions (e.g., when using Waystones). Instead of relying on their tiny legs and pathfinding AI to catch up, your player code will now safely scoop up any actively following hamsters (and their babies if the babies are following them), hold them in a little NBT pocket while the world loads, and drop them at your new location 0.75 seconds later. Void Rescue Protocol** If a player falls into the void and dies with hamsters on their shoulders, the hamsters will no longer spawn in the void and immediately perish. The system will safely teleport them back to their linked bed. If they do not have a linked bed, they will be sent to the player's personal respawn point or the world spawn. UI, HUD, & Audio** Jade Integration** Added comprehensive Jade overlay integration that reveals a hamster's exact genetic makeup (base coat, wild overlay, breeding overlay, eye genotype, etc.) when you look at them. Enabled without needing to turn on debug mode to help with breeding. Fully customizable. Each setting comes with its own toggle, and you can decide which ones show up when you sneak to keep the Jade HUD de-cluttered. GUI Renaming System** Players can now rename their hamsters directly from the Hamster Inventory screen. Features dynamic down-scaling to ensure long names always fit perfectly within the UI constraints. An interactive pencil icon and underline display when hovering/typing. New Config Options ( UI & Quality of Life > Hamster Renaming)**Enable GUI Renaming: Master toggle for the feature.Consume Name Tag: Forces players to sacrifice a Name Tag from their inventory (or the hamster's cheeks) to finalize the rename.Pencil Icon Placement: Allows swapping the icon to the left or right of the text for those who read in different directions.New Audio & Visuals** Added a brand new anim_hamster_cheek_unload animation used for gifting items, complete with item and spit particle effects.Added 4 new scratching sound variations for the cleaning animation, and switched to keyframes for the SFX to make it less repetitive and more realistic. This also has the side effect of muting the sound effect if the hamster is not on screen, and thus not being rendered. This means you will no longer hear nearby hamsters cleaning unless you can also see them. Added dynamic item sounds (clink, squish, thud, etc.) to the new gifting sequence. Commands & Admin Tools** Advanced Spawning & Testing Commands** Added /ahp spawn hamster <basePalette> <wildPattern> <wildPalette> <breedPattern> <breedPalette> <eyes>. This command features a custom Brigadier auto-complete engine that suggests exact, human-readable palette and pattern names as you type, allowing you to easily test specific genetic combinations.Added /ahp spawn_all_bases_2D. Systematically lines up every single hamster color base in the game (including custom community additions), sorted cleanly into rows by their dynamically determined, mathematical color zone.Added /ahp spawn_all_bases_3D. Spawns the hamsters hovering in a physical 3D "cylinder" representing their Hue/Saturation/Brightness coordinates. This is useful for the **Breeding Inheritance and Visualization Tool** (see below).Hue** = the degree of the circle (0-360) Saturation** = the radius of the circle (more saturated colors are closer to the edge) Brightness** = the height of the cylinder (brighter hamsters are closer to the top) By default, each /ahp spawn_all_bases... command spawns just the 45 base colors, but each one comes with 3 optional arguments to change the number of hamsters spawned: 1. [with_wild_overlays] Displays all 3,231 hamster variants that can spawn naturally in the wild.
2. [with_sample_breeding_overlays] Displays genetic combinations of every wild hamster but adds in a small sample of three breeding overlays (Tortoise Shell, Silver, and Rust). Due to the triple-multiplication math involved, this heavily increases the total number of hamsters spawned (from 3,231 up to 9,693) creating a much bigger display.
3. [author] only uses color palletes from a certain author (e.g., jimcerberus or default).
- Added
/ahp spawn_all_possible_permutations_THIS_CAN_BREAK_YOUR_WORLD. Exactly what it sounds like. Don't run it unless you have a super-flat world, a fire extinguisher for your PC, and a lot of patience. Note that every time I have run this command, my server tick speed never quite returned to baseline— even after deleting all the hamsters that were spawned using /kill @e[type=!player].Added /ahp print_genetics_report command, allowing server operators to recalculate and view the current 3D color-space math of the genetics engine at runtime. Useful because it dynamically updates its readout based on your exact AhpWorldGenConfig wild overlay settings, so you can see how your changes are affecting the total possible variant numbers without having to spawn them all.Tree Heist History Command** Added /ahp reset_tree_economy for quick clearing of tree depletion memory without needing to open the config screen.Advancements** Advancement: Carat Confusion** Triggers when a hamster leads you to Gold Ore instead of Diamond. Advancement: Load-Bearing Human** Triggers when you mount 3 hamsters simultaneously (Right, Left, Head). Genetic Progression Advancements** Added "The Collector" advancement path tracking unique wild variants tamed (up to dynamic maximum based on configuration limits). Added "The Breeder" advancement path tracking unique bred combinations (up to 1,000,000). Added a conditional advancement "Seeing Red" for successfully breeding the recessive eye trait. Does not trigger if red eyes have been turned off in the config. Implemented high-performance, non-bloating NBT storage using IntArrays to track thousands of HamsterGenome hashes without lagging the player entity.Guidebook Enhancements** Guidebook Delivery Fallback** Added a new configuration option that acts as a fallback for modpacks that disable auto-guidebook delivery on login. If enabled (default), players will automatically be given the Hamster Tips guidebook and receive a chat prompt the very first time they spot a wild hamster from <=10 blocks away. Targeting calculation includes wiggle room to ensure the event triggers even if the player's crosshair isn't perfectly on the hamster's hit box. Only triggers once, and only if the player has never yet received the guidebook (regardless of current inventory status). Lectern Reading** Added code for placing the Hamster Tips guide book into a lectern and an event handler so you can read it. You can now display your rodent knowledge in your base or wherever. Hamster Tips Guidebook Improvements** The *Hamster Tips* guidebook now uses a custom string processor to pull live data directly into the text, so I can do things like automatically displaying the exact number of mathematically possible wild variants or the name of your dynamically configured Lure Item instead of hardcoding "Cheese". Updated the "Regional Rodents" entry to explain the new biome-adaptive color logic, Wild Overlays and Jade integration. Added a new "Breeding" entry in _The Hamster Life_ chapter detailing the genetic mechanics, recessive red eyes, and feral youth mechanics. Added a new "Admin Commands" entry in _The Kitchen Drawer_ chapter detailing the various new (and old) commands the mod has to offer since some of them (especially the new ones) are super useful. Pixie-Dust Crown for Supporters** Added a dynamic, spinning, bobbing particle crown that renders above the heads of mod supporters. Uses a custom Pixie Dust particle system featuring a dense, short-lived, shimmering effect.Emits a subtle sparkling sound and includes 5 different themes (Gold, Crimson, Lavender, Ice, Emerald) by manipulating the HSB color values of a single grayscale texture at runtime. Automatically hides in first-person view to prevent visual obstruction. Powered by a remote manager that pulls configuration data asynchronously from GitHub and caches it for offline use. You will need to briefly connect to the Internet while launching Minecraft at least once to verify your ownership of the Crown. After that you can play offline and still see it! Configurable Aesthetics** Added a new Supporter Perks config group.Added a global toggle to disable rendering of all crowns if you hate fun. Added a global toggle to disable sound effects of all crowns. Added a local toggle to allow rendering your own crown in first-person mode if you want to both obstruct your view and thrill yourself. Added sliders for sound volume, particle count, crown radius, crown height, crown thickness, and vertical offset. Added a new "Toggle Supporter Crown" keybind allowing users to show/hide their own crown from both themselves and the rest of the server. A single press cycles the crown to the next available color theme, while a double-tap toggles the crown's visibility. Supporters can pick their own crown color. Your preference syncs instantly to all other players looking at you utilizing DataTracker networking.
### Changed
- Location-Centric Spawning Overhaul**
- Completely rewrote the world generation spawning logic. Instead of mapping individual hamster colors to biomes, biomes are now grouped into 9 "Spawning Environments" (e.g., Icy, Sandy, Forest, etc.)
- Each environment rolls against weighted hamster color groups. This ensures that whether a texture is procedurally generated or community-made, it mathematically evaluates its own color and automatically spawns in a biologically appropriate location.
- Diamond Sniffing Visuals & Audio**
- Added directional animations to indicate whether a buried diamond ore is above or below the hamster when it's sniffing for one and the path is obstructed.
- Added a dynamic "quick bounce" animation that intermittently triggers when the diamond ore is hidden somewhere above the hamster.
- Added a new head-shake sound effect that plays when the hamster is sniffing for ore and gets confused.
- Sweet Potato Easter Egg**
- The "Sweet Potato" Easter egg now applies a unique custom texture to the hamster, thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com)!
- Renaming a hamster "Sweet Potato" hides its normal genetics (base coat, overlays, and eye color) without permanently deleting them.
- Sweet Potato hamsters can still breed, and their offspring will genetically inherit traits mathematically blended from the sweet potato's unique color palette, but they do not spawn in the wild.
- Jade HUD Config Settings**
- Added a new "Jade Overlay Settings" section to the config under "UI & Quality of Life".
- Displays complex genetic info (Age, Base Coat, Wild Overlay, Breeding Overlay, Eye Color) by default.
- Added a "Require Sneaking" toggle (disabled by default) allowing you to hide the genetic overlay unless you are actively sneaking.
- Added individual toggles for every piece of my custom genetic info shown in the Jade overlay.
- Added additional toggles for selectively disabling default Jade info lines (Name, Health, Growth Time, Owner, Inventory) specifically for hamsters without impacting other entities, and a toggle to link their visibility to the player's sneaking state, allowing you to completely customize the HUD to your liking.
- Built a smart-formatting engine so that community texture IDs are automatically converted into localized, human-readable titles on the HUD (e.g.,
cheesecake_mocha.png -> "Cheesecake Mocha").Statue Performance & AI Toggling** Hamsters spawned with their AI disabled will now completely freeze their animation playback and no longer emit ambient idle squeaks. This attempts to reduce client-side rendering lag when hundreds of thousands of hamsters are on screen for testing, but Java itself struggles with that many cubes on screen, so it's still laggy if you try to look at 2 million+ hamsters simultaneously. You can now tame an AI-disabled hamster, which will instantly "wake it up" and turn it into a real, fully functional hamster. Added an Allow Taming to Re-Enable AI toggle to the config in case you're a server owner who wants to sell specific hamster breeds in a shop. If you have OP permissions on your server, you can turn this off to prevent players from taming and "waking up" frozen hamsters, allowing them to be used as shop displays or decorative statues.Mod Page/README** The README was functioning as a marketing poster, a technical manual, a credits roll, and a tutorial. That is too many jobs for one file. It was getting too large, so I have reorganized it, reworded it, and split a few things off into other easily accessible files, so the README only has one job now. Mount Priority** Changed default config value to HEAD_FIRST.Action Bar Config Toggles** Grouped all action bar message toggles (Shoulder Dismount, Tree Heist Start, Bed Break, Tamed Baby Warning, and Display Duration) into a new "Action Bar Messages" sub-category under "UI & Quality of Life" for easier access. Guidebook** Updated Hamster Bed entry to explicitly mention the Totem of Undying requirement for respawning. Guidebook Effects** If you obtain the Hamster Tips guidebook while viewing a chest or crafting screen, the "rediscovered" visual and audio effects will now be postponed until you close the screen, ensuring the effects do not play while you're looking at your inventory. If you keep the screen open for longer than 5 seconds after obtaining the book, the effects are silently cancelled. Cucumber Rebalance** Sliced Cucumbers are no longer inexplicably nutritious. Their default food value has been dropped from 2 hearts to 0.5 hearts to match items like Dried Kelp. Hamster Hitbox Adjustment** Shrunk the physical hitbox of hamsters by 15% to more accurately match their actual visual model size. Note: Because the bounding box is now smaller, you will need to aim slightly more accurately when trying to interact with a hamster.* Patchouli Version** Updated the internal guidebook generation logic to accommodate API breaking changes introduced in Patchouli version 1.21.1-93.You must update Patchouli to the latest version or the game will not launch. Shoulder Animation Configs** Replaced the single Forced Animation State setting with three distinct settings. You can now independently force the Head, Left Shoulder, and Right Shoulder hamsters into specific animation loops (when dynamic animations are disabled).Tree Heist Exits** Hamsters will now perform a small outward jump, launching themselves away from the tree upon successfully completing a Tree Heist. Breeding Cooldown Config** The config setting for breeding cooldown has been changed from Ticks to Seconds to make it significantly easier to manage with the slider.
### Fixed
- Config Live Changes**
- Fixed an issue where changing settings in the
World Gen & Loot config (such as wild bush or hamster spawning settings) required a full game restart to take effect. Saving changes to any config now recalibrates the mod's logic caches on both the client and the server.Visual Rotation Glitch** Attempted to fix an issue where using teleportation mods (like Waystones) or interrupting animations could cause the hamster's model to become permanently rotated backwards or upside down on the client side. I can't be 100% certain about this fix yet, because no one has been able to figure out exactly what causes it and I can't re-create it myself, so let me know if you run into it. Hamster Stretching with Shaders** Fixed a visual bug where hamsters would stretch to extreme sizes during multiplayer server lag or when pausing the game. Dismount Bug** Fixed an issue where holding down the Sneak key for more than a second would cause the OS's auto-key-repeat feature to spam the game with inputs, dismounting all of your shoulder hamsters rapidly. You can now safely hold Sneak without losing your friends. This bug has existed ever since the double-tap setting was added, but I hadn't found it because I usually play with Sneak set to "Toggle" (which means I have no reason to hold it down for extended periods). Memory Optimization** Implemented pre-caching for texture identifiers and simplified rotation math in the render loop to eliminate extra memory objects being generated every frame. Spanish Localization** Some strings in the Hamster Tips guidebook were still outdated (i.e., the Accessories and Sunflower pages). Malformed Recipe** The sliced_cucumber_from_cutting_board.json` recipe for compatibility with Farmers Delight failed to load on 1.20.1 due to a typo.

# **The Procedural Genetics Update**
Hamsters now utilize a fully procedural and configurable genetics engine with **3,158** new wild variants, **2,285,046** potential breeding outcomes, recessive red eyes, 13 new advancements, and a guidebook update that explains everything. Added comprehensive breeding settings to balance obsessions with server tick speed (looking at you, Janet). Also many bugs were squashed, and hamsters learned to play tag and spit out gifts from their cheeks. Make sure you update Patchouli to the latest version or your game won't launch!

### Added
- Procedural Genetics & Texture System**
- Procedural Genetics Engine**
- Hamsters are no longer pre-defined, hardcoded variants. Every hamster now possesses a fully serialized
detailing its precise genetic makeup across six distinct traits.This was accomplished by developing a 3D Hue/Saturation/Brightness (HSB) Cartesian color space. The mod uses this to mathematically map the exact color coordinates of every hamster variant into a three-dimensional neural network, which is dynamically used to calculate genetic relationships, mutations, overlay exclusion rules, and environment-spawning rules on the fly. I got the idea for creating the textures programmatically like this because that's how I made the original textures in Photoshop— using various Gradient Maps applied to a single, grayscale texture. Then I realized Java code can do the same thing! The total number of unique hamster types that spawn in the wild is now **3,231** by default, and the number of genetically inheritable hamster permutations from breeding is now **over 2.2 Million**. Want to understand the math?** Keep reading below— look for the _"Advanced Spawning & Testing Commands"_ section. I have added all sorts of fancy commands and tools to walk you through the breeding system in a way that is (hopefully) easy to understand. Dynamic Palette Swapping** Built an optimized, client-side dynamic texture generator. Instead of bloating your hard drive with over 2 million distinct PNG files, the mod dynamically recolors grayscale fur templates at runtime using custom genetic palette hex code data I designed based off my Photoshop workflow, then mixes them with hard-coded PNGs from the community. I realized the original hamster variants were just gradient maps applied to a grayscale texture in Photoshop. So, naturally, I invested an unreasonable amount of effort rebuilding Photoshop's Gradient Map tool inside Java. Does this save file space? Sort of, though tiny PNGs don't take up much space anyway. But it makes the system infinitely scalable. If I add just one new grayscale pattern or community-made texture in the future, the Java math will automatically multiply it across every single other variant in the game. For now, consider it an over-engineered proof of concept. Community Hamster Textures** Developed a parallel pipeline that automatically scans, analyzes, and genetically categorizes static, community-made PNG textures directly from the mod's JAR file. These static textures are seamlessly integrated into the procedural breeding pool alongside my programmatic colors. The rendering engine can automatically composite custom community textures into overlay masks. This means hamsters can spawn with community-made palettes serving as the color for their overlay spots and splotches! Thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com), we have 18 brand-new base hamster variants spawning in the wild! (Including *Cheesecake Mocha, Blue Fawn, Pearl Rose, Sable,* and 14 more). You can see them all in-game using the new spawn commands (see below). Expanded Overlays** Overlays are no longer just white. Wild Overlays:** Naturally spawning hamsters can now have overlays in any color that is closely related to White, Cream, or Gray, with a few configurable exceptions. To keep things looking natural, the default config ensures wild overlays are always brighter & less saturated than the base coat, Cream is disallowed on a Lavender or Blue base coat, and cave-spawned hamsters can only receive Gray overlays to help them blend in. Breeding Overlays:** A completely new secondary overlay layer, unlocked exclusively through breeding (45% chance when two first-generation wild hamsters breed). These are chosen based on the midpoint between the parents' base color in the 3D color-space coordinate system, with a bit of jitter so the baby won't always look the same when you breed two parents repeatedly, so the possibilities are nearly endless. These overlays will mathematically avoid copying the same shape/pattern as the wild overlay, to ensure they are not hidden/covered up by it. Breeding & Lifecycle Mechanics** Breeding Inheritance and Visualization Tool** Here's how it works:** When breeding two hamsters together, the color for the baby (and its overlay colors) are chosen based on a connected line between the two parents in the 3D color-space coordinate system. This means babies will tend towards the mathematical center, but occasionally one parent's color traits will strongly dominate the outcome, mimicking real-world genetics and providing visual variety within a single hamster family even if you breed the same two parents together repeatedly. Outcome Visualizer:** You can right-click two hamsters inside the 3D variants layout ( /ahp spawn_all_bases_3D) with the Hamster Tips guidebook to visualize the genetic probability distribution for their offspring via a cloud of Wax On particles. The particle spawning logic uses the exact same probability math that is used when creating babies, so it gives you a perfectly accurate representation of potential outcomes.Config Settings and Real-time Controls** Genetic Variance**: Adjusts how much a baby's base color can deviate from the exact center between its parents. Think of this as the "length" of the line between the parents. Genetic Mutation Rate**: Adjusts the random color scatter/mutations applied to babies. Think of this as the "thickness" of the line. Simulated Offspring Per Second**: Adjust the density of the 3D visualizer particle cloud. Each particle represents a potential baby. Real-time Controls:** While holding the guidebook, you can dynamically tweak the shape of the genetic probability cloud using the arrow keys: Left/Right Arrows adjust Genetic Variance; Up/Down Arrows adjust Genetic Mutation Rate. Server and Client Sync:** Since the particle visualizer is driven by the literal server-side breeding math, which is driven by the config for your server, and the changes you make with the arrow keys directly alter that config, the changes will take effect immediately for any future babies. Recessive Eye Genetics** Hamsters now possess dominant (Black) and recessive (Red) eye genetics. Red eyes do not exist in the wild. They are genetically tied to the "diluteness" (brightness/saturation) of the hamster's coat. A fully dilute hamster has up to a 50% chance of spawning with a recessive red eye gene. By selectively breeding highly dilute hamsters, players can uncover carriers ( Br) and eventually breed Red-Eyed (rr) variants. Uses punnet squares.Baby Growth Mechanics** You can now feed baby hamsters standard hamster food items to accelerate their growth. To balance this with their natural pickiness, a new config option ( Disable Baby Food Refusal) allows you to bypass their desire for dietary variety specifically for babies if you want. This is turned off by default, so to bypass their pickiness you'll need lots of **Hamster Food Mix** if you want to quickly grow them up.Feeding baby hamsters visually and mechanically accelerates their growth in smooth, continuous increments, similar to vanilla horses. Their "extra big head" proportions scale dynamically as they grow. Breeding Limitations** Added comprehensive config settings to manage hamster breeding for server owners who want to keep the population under control. Added a global Enable Breeding toggle (on by default) to instantly shut down all romance.Added a configurable Max Breeding Cycles limit per hamster to stop them from infinitely multiplying (off by default).Added a Limit Breeding By Player toggle. (also off by default). Limits can be assigned per-player based on Minecraft days or Real Life days, or simply capped as a lifetime maximum limit. Includes feedback to explain what's happening when attempting to over-feed beyond the limit.Added a /ahp reset_player_breeding_history command for server operators to reset their own breeding history.Added a /ahp reset_hamster_breeding_history command for server operators to reset a specific hamster's timesBred quota to zero.Added a convenient "Reset Breeding History" button in the Config screen that executes the command for the user (requires OP permissions). Configurable Litter Size** Added to config sliders allowing you to set the minimum and maximum litter size when hamsters get into hanky-panky. The final size of the litter will be a random number between the min and max. Breeder Whitelist** Added a config list allowing specific players to bypass the global breeding ban. In case your server needs a designated rodent baron. Post-Breeding Animation** Hamsters will now crouch down and lovingly inspect their baby(s) after the litter is born, spawn heart particles, and make affectionate sounds shortly after successfully contributing to your growing population problem. Wild Baby Configuration** Added Babies Spawn Wild setting. When enabled, babies are born feral and do not inherit their parent's ownership status, letting multiplayer groups decide who claims them.When untamed, babies no longer flee from players, making them easier to manage. Parent-Following** Babies will now randomly select a parent to follow until adulthood, instead of following their owner. Wild baby hamsters will switch to following the player if their parent is currently mounted on the player's shoulder. They will automatically resume following the parent once it is dismounted. If you want the baby to follow you instead, you must first tame it, then you can break its connection to the parent by right-clicking it with a Lure Item (Cheese by default). Added a config toggle to disable the action bar message that warns you when a newly tamed baby hamster refuses to follow you because it's still attached to its parent. Age Tracking** Hamsters now track their absolute lifetime age in ticks. Wild hamsters spawn with a random age between 1 and 30 days. Added /ahp set_age command to manually override a hamster's age (since older hamsters will start at 0 days old upon updating to this version of the mod). It accepts units (days, months, years) and provides autocomplete suggestions.If you do not specify a target, it will automatically apply to the hamster you are currently looking at. The Jade HUD overlay displays the hamster's age alongside its genetic data. Added a new Display IRL Age config setting that dictates how fast the hamster ages. If true, their age progresses at 1/72nd the normal speed (matching the real-world 24-hour cycle).Performance Improvements** Significant Overall Improvements** Flattened the entire visual render layer stack (base coat, wild overlays, breeding overlays, skin, eyes, armor, and accessories) into a single, dynamically composited texture at runtime. This completely eliminates all secondary GeoRenderLayer passes. Every hamster, regardless of its complex genetics or equipped items, now costs exactly one draw call to render (previously it was anywhere from 2 to 8!), resulting in a massive performance boost. Especially noticeable when numerous hamsters are on screen at the same time.Bare-Bones Ultra Performance Mode** Added a new Performance Mode toggle in the config (and an assignable keybind) designed specifically for viewing absurd numbers of hamsters simultaneously without melting your GPU.When enabled, it bypasses the dynamic texture engine entirely (falling back to a single flat texture) and hides almost all the model's geometry. The hamsters essentially become grayscale cubes, stripping away nearly all matrix-calculation overhead. The Jade HUD overlay will still display their exact genetic information, because the server never forgets what they are actually supposed to look like. New Config Settings** Wild Overlay Configurability** Added new Allowed Wild Overlay Zones list to the World Gen & Loot config. This allows server owners/modpack makers to explicitly control which color zones the genetics engine is allowed to use when picking an overlay for a naturally spawning hamster. Defaults to natural colors (WHITE, LIGHT_GRAY, DARK_GRAY, and CREAM).Added new Restricted Base Colors and Clashing Overlay Colors lists. By default, these prevent CREAM and DARK_GRAY wild overlays from spawning on top of BLUE and LAVENDER base coats, as these color combinations tend to look a bit strange visually.Added new Enforce Brighter Overlays and Enforce Muted Overlays toggles. Allows players to disable the overlay filtering that prevents saturated colors (like Cream) from spawning on muted bases (like Black) and darker colors from being used as overlays on top of lighter bases.Modifying the overlay settings can dramatically change the number of possible combinations for wild hamsters (3,231 by default). Red Eye Config Toggle** Don't like the red eye hamsters? You can visually disable that for your own client via a new config toggle, which makes them appear to have black eyes. Friendly Fire Config Toggle** Added Prevent Owner Friendly Fire to the Core config toggles.When enabled, players can no longer accidentally damage their own tamed hamsters. Disabled by default to remain vanilla-friendly. In the next update (hopefully), this setting will be tied to a new item: the **Acorn Ring**. I also plan to integrate with the **Trinkets** mod so you can use a trinket slot for it. Configurable Cuisine** You can now configure the nutrition and saturation values for all food items added by the mod (Cucumbers, Green Beans, Food Mix). Changed nutrition/saturation values are dynamically reflected in AppleSkin's "on-eat" HUD preview. **Unfortunately due to major API changes between MC versions, this only works on 1.21.1.* Max Mounted Hamsters Config** Added a configuration slider under 'Shoulder Hamster Settings > Core Settings' allowing players to limit the maximum number of hamsters that can be mounted simultaneously (1 to 3). Gameplay Mechanics & Interactions** Tag Mini-Game** Hamsters can now initiate a playful game of tag. If you maintain eye contact with a hamster for a few seconds, it will squeak and excitedly run away. The Chase:** The hamster will flee if you get too close and stop to playfully taunt you if you fall too far behind. Payoff:** Successfully "catching" (right-clicking) the hamster before it gets bored ends the game triggers a celebration. The hamster will then spit out a random item from its cheek pouches as a gift (pulling from the configurable cheek pouch loot lists). Stranger Danger:** By default, you can play tag with wild hamsters and hamsters owned by other players. (Can be disabled in config). Configurable Limits and Rewards** Added configs to control how often they want to play, the cooldown between games, and an anti-abuse cap on how many times a single player can play the game per in-game day (so they can't farm rewards). Added configs to control rewards: By default, hamsters will randomly pick an item from their configurable "Cheek Pouch Loot" list (the list of potential items a wild hamster might spawn with). The item does not have to be in the hamster's cheek pouch for it to give it as a gift. That can be disabled, in which case the hamster will choose the gift from a separate "Custom Tag Rewards" list in the config, which means you can make your hamster give you a diamond or any modded item (or whatever you want) when you catch it after a game of tag. Only server moderators can modify this of course. Dynamic Gaze** Hamsters will now sustain eye contact with you indefinitely, provided you are nearby and continue looking back at them, and of course as long as they don't start a game of tag. Hamster Yeet Overhaul** Thrown hamsters are now officially registered as ProjectileEntity instances while airborne. This provides automatic, out-of-the-box compatibility with external mods that use targets or hoops (such as the Tin Hoops in Caverns and Chasms).Thrown hamsters now experience dynamic physics upon impact. They will ricochet backward off of walls and entities, or skip forward when hitting floors and ceilings. Thrown hamsters now dynamically query and broadcast the native sound of the block or entity they strike (including modded blocks/entities). Impact physics are magnified when hitting Slime blocks, and completely absorbed by Honey blocks. Added a new config toggle (true by default) allowing thrown hamsters to damage their owner. Throwing your own rodent straight up in the air will now result in a realistic, concussive reunion on the way back down. Precision Tree Heists** Right-clicking Oak Leaves with a lure item (Cheese) while a hamster is on your shoulder will now initiate a "Precision Tree Heist." This sets that specific leaf block as the guaranteed exit point for the hamster. While a precision heist is active, right-clicking in the air with the lure item will set the hamster's exit direction to match the direction you are currently looking. Why?** This allows you to precisely control the exact block and angle by which your hamster will exit the tree, which makes for much more predictable recording sessions. Moonwalking Easter Egg** Name your hamster "Michael Jackson" or "Steve Irwin" and it will rotate backwards and remain that way until you change the name again. Expanded Default Diet** Hamsters can now eat seeds from almost any mod out-of-the-box. Added a robust union tag to the default config that automatically syncs with #c:seeds and #forge:seeds to ensure compatibility across all versions and mod loaders.Failsafes & Rescues** Teleport Rescue Protocol** Overhauled how hamsters follow you across vast distances or dimensions (e.g., when using Waystones). Instead of relying on their tiny legs and pathfinding AI to catch up, your player code will now safely scoop up any actively following hamsters (and their babies if the babies are following them), hold them in a little NBT pocket while the world loads, and drop them at your new location 0.75 seconds later. Void Rescue Protocol** If a player falls into the void and dies with hamsters on their shoulders, the hamsters will no longer spawn in the void and immediately perish. The system will safely teleport them back to their linked bed. If they do not have a linked bed, they will be sent to the player's personal respawn point or the world spawn. UI, HUD, & Audio** Jade Integration** Added comprehensive Jade overlay integration that reveals a hamster's exact genetic makeup (base coat, wild overlay, breeding overlay, eye genotype, etc.) when you look at them. Enabled without needing to turn on debug mode to help with breeding. Fully customizable. Each setting comes with its own toggle, and you can decide which ones show up when you sneak to keep the Jade HUD de-cluttered. GUI Renaming System** Players can now rename their hamsters directly from the Hamster Inventory screen. Features dynamic down-scaling to ensure long names always fit perfectly within the UI constraints. An interactive pencil icon and underline display when hovering/typing. New Config Options ( UI & Quality of Life > Hamster Renaming)**Enable GUI Renaming: Master toggle for the feature.Consume Name Tag: Forces players to sacrifice a Name Tag from their inventory (or the hamster's cheeks) to finalize the rename.Pencil Icon Placement: Allows swapping the icon to the left or right of the text for those who read in different directions.New Audio & Visuals** Added a brand new anim_hamster_cheek_unload animation used for gifting items, complete with item and spit particle effects.Added 4 new scratching sound variations for the cleaning animation, and switched to keyframes for the SFX to make it less repetitive and more realistic. This also has the side effect of muting the sound effect if the hamster is not on screen, and thus not being rendered. This means you will no longer hear nearby hamsters cleaning unless you can also see them. Added dynamic item sounds (clink, squish, thud, etc.) to the new gifting sequence. Commands & Admin Tools** Advanced Spawning & Testing Commands** Added /ahp spawn hamster <basePalette> <wildPattern> <wildPalette> <breedPattern> <breedPalette> <eyes>. This command features a custom Brigadier auto-complete engine that suggests exact, human-readable palette and pattern names as you type, allowing you to easily test specific genetic combinations.Added /ahp spawn_all_bases_2D. Systematically lines up every single hamster color base in the game (including custom community additions), sorted cleanly into rows by their dynamically determined, mathematical color zone.Added /ahp spawn_all_bases_3D. Spawns the hamsters hovering in a physical 3D "cylinder" representing their Hue/Saturation/Brightness coordinates. This is useful for the **Breeding Inheritance and Visualization Tool** (see below).Hue** = the degree of the circle (0-360) Saturation** = the radius of the circle (more saturated colors are closer to the edge) Brightness** = the height of the cylinder (brighter hamsters are closer to the top) By default, each /ahp spawn_all_bases... command spawns just the 45 base colors, but each one comes with 3 optional arguments to change the number of hamsters spawned: 1. [with_wild_overlays] Displays all 3,231 hamster variants that can spawn naturally in the wild.
2. [with_sample_breeding_overlays] Displays genetic combinations of every wild hamster but adds in a small sample of three breeding overlays (Tortoise Shell, Silver, and Rust). Due to the triple-multiplication math involved, this heavily increases the total number of hamsters spawned (from 3,231 up to 9,693) creating a much bigger display.
3. [author] only uses color palletes from a certain author (e.g., jimcerberus or default).
- Added
/ahp spawn_all_possible_permutations_THIS_CAN_BREAK_YOUR_WORLD. Exactly what it sounds like. Don't run it unless you have a super-flat world, a fire extinguisher for your PC, and a lot of patience. Note that every time I have run this command, my server tick speed never quite returned to baseline— even after deleting all the hamsters that were spawned using /kill @e[type=!player].Added /ahp print_genetics_report command, allowing server operators to recalculate and view the current 3D color-space math of the genetics engine at runtime. Useful because it dynamically updates its readout based on your exact AhpWorldGenConfig wild overlay settings, so you can see how your changes are affecting the total possible variant numbers without having to spawn them all.Tree Heist History Command** Added /ahp reset_tree_economy for quick clearing of tree depletion memory without needing to open the config screen.Advancements** Advancement: Carat Confusion** Triggers when a hamster leads you to Gold Ore instead of Diamond. Advancement: Load-Bearing Human** Triggers when you mount 3 hamsters simultaneously (Right, Left, Head). Genetic Progression Advancements** Added "The Collector" advancement path tracking unique wild variants tamed (up to dynamic maximum based on configuration limits). Added "The Breeder" advancement path tracking unique bred combinations (up to 1,000,000). Added a conditional advancement "Seeing Red" for successfully breeding the recessive eye trait. Does not trigger if red eyes have been turned off in the config. Implemented high-performance, non-bloating NBT storage using IntArrays to track thousands of HamsterGenome hashes without lagging the player entity.Guidebook Enhancements** Guidebook Delivery Fallback** Added a new configuration option that acts as a fallback for modpacks that disable auto-guidebook delivery on login. If enabled (default), players will automatically be given the Hamster Tips guidebook and receive a chat prompt the very first time they spot a wild hamster from <=10 blocks away. Targeting calculation includes wiggle room to ensure the event triggers even if the player's crosshair isn't perfectly on the hamster's hit box. Only triggers once, and only if the player has never yet received the guidebook (regardless of current inventory status). Lectern Reading** Added code for placing the Hamster Tips guide book into a lectern and an event handler so you can read it. You can now display your rodent knowledge in your base or wherever. Hamster Tips Guidebook Improvements** The *Hamster Tips* guidebook now uses a custom string processor to pull live data directly into the text, so I can do things like automatically displaying the exact number of mathematically possible wild variants or the name of your dynamically configured Lure Item instead of hardcoding "Cheese". Updated the "Regional Rodents" entry to explain the new biome-adaptive color logic, Wild Overlays and Jade integration. Added a new "Breeding" entry in _The Hamster Life_ chapter detailing the genetic mechanics, recessive red eyes, and feral youth mechanics. Added a new "Admin Commands" entry in _The Kitchen Drawer_ chapter detailing the various new (and old) commands the mod has to offer since some of them (especially the new ones) are super useful. Pixie-Dust Crown for Supporters** Added a dynamic, spinning, bobbing particle crown that renders above the heads of mod supporters. Uses a custom Pixie Dust particle system featuring a dense, short-lived, shimmering effect.Emits a subtle sparkling sound and includes 5 different themes (Gold, Crimson, Lavender, Ice, Emerald) by manipulating the HSB color values of a single grayscale texture at runtime. Automatically hides in first-person view to prevent visual obstruction. Powered by a remote manager that pulls configuration data asynchronously from GitHub and caches it for offline use. You will need to briefly connect to the Internet while launching Minecraft at least once to verify your ownership of the Crown. After that you can play offline and still see it! Configurable Aesthetics** Added a new Supporter Perks config group.Added a global toggle to disable rendering of all crowns if you hate fun. Added a global toggle to disable sound effects of all crowns. Added a local toggle to allow rendering your own crown in first-person mode if you want to both obstruct your view and thrill yourself. Added sliders for sound volume, particle count, crown radius, crown height, crown thickness, and vertical offset. Added a new "Toggle Supporter Crown" keybind allowing users to show/hide their own crown from both themselves and the rest of the server. A single press cycles the crown to the next available color theme, while a double-tap toggles the crown's visibility. Supporters can pick their own crown color. Your preference syncs instantly to all other players looking at you utilizing DataTracker networking.
### Changed
- Location-Centric Spawning Overhaul**
- Completely rewrote the world generation spawning logic. Instead of mapping individual hamster colors to biomes, biomes are now grouped into 9 "Spawning Environments" (e.g., Icy, Sandy, Forest, etc.)
- Each environment rolls against weighted hamster color groups. This ensures that whether a texture is procedurally generated or community-made, it mathematically evaluates its own color and automatically spawns in a biologically appropriate location.
- Diamond Sniffing Visuals & Audio**
- Added directional animations to indicate whether a buried diamond ore is above or below the hamster when it's sniffing for one and the path is obstructed.
- Added a dynamic "quick bounce" animation that intermittently triggers when the diamond ore is hidden somewhere above the hamster.
- Added a new head-shake sound effect that plays when the hamster is sniffing for ore and gets confused.
- Sweet Potato Easter Egg**
- The "Sweet Potato" Easter egg now applies a unique custom texture to the hamster, thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com)!
- Renaming a hamster "Sweet Potato" hides its normal genetics (base coat, overlays, and eye color) without permanently deleting them.
- Sweet Potato hamsters can still breed, and their offspring will genetically inherit traits mathematically blended from the sweet potato's unique color palette, but they do not spawn in the wild.
- Jade HUD Config Settings**
- Added a new "Jade Overlay Settings" section to the config under "UI & Quality of Life".
- Displays complex genetic info (Age, Base Coat, Wild Overlay, Breeding Overlay, Eye Color) by default.
- Added a "Require Sneaking" toggle (disabled by default) allowing you to hide the genetic overlay unless you are actively sneaking.
- Added individual toggles for every piece of my custom genetic info shown in the Jade overlay.
- Added additional toggles for selectively disabling default Jade info lines (Name, Health, Growth Time, Owner, Inventory) specifically for hamsters without impacting other entities, and a toggle to link their visibility to the player's sneaking state, allowing you to completely customize the HUD to your liking.
- Built a smart-formatting engine so that community texture IDs are automatically converted into localized, human-readable titles on the HUD (e.g.,
cheesecake_mocha.png -> "Cheesecake Mocha").Statue Performance & AI Toggling** Hamsters spawned with their AI disabled will now completely freeze their animation playback and no longer emit ambient idle squeaks. This attempts to reduce client-side rendering lag when hundreds of thousands of hamsters are on screen for testing, but Java itself struggles with that many cubes on screen, so it's still laggy if you try to look at 2 million+ hamsters simultaneously. You can now tame an AI-disabled hamster, which will instantly "wake it up" and turn it into a real, fully functional hamster. Added an Allow Taming to Re-Enable AI toggle to the config in case you're a server owner who wants to sell specific hamster breeds in a shop. If you have OP permissions on your server, you can turn this off to prevent players from taming and "waking up" frozen hamsters, allowing them to be used as shop displays or decorative statues.Mod Page/README** The README was functioning as a marketing poster, a technical manual, a credits roll, and a tutorial. That is too many jobs for one file. It was getting too large, so I have reorganized it, reworded it, and split a few things off into other easily accessible files, so the README only has one job now. Mount Priority** Changed default config value to HEAD_FIRST.Action Bar Config Toggles** Grouped all action bar message toggles (Shoulder Dismount, Tree Heist Start, Bed Break, Tamed Baby Warning, and Display Duration) into a new "Action Bar Messages" sub-category under "UI & Quality of Life" for easier access. Guidebook** Updated Hamster Bed entry to explicitly mention the Totem of Undying requirement for respawning. Guidebook Effects** If you obtain the Hamster Tips guidebook while viewing a chest or crafting screen, the "rediscovered" visual and audio effects will now be postponed until you close the screen, ensuring the effects do not play while you're looking at your inventory. If you keep the screen open for longer than 5 seconds after obtaining the book, the effects are silently cancelled. Cucumber Rebalance** Sliced Cucumbers are no longer inexplicably nutritious. Their default food value has been dropped from 2 hearts to 0.5 hearts to match items like Dried Kelp. Hamster Hitbox Adjustment** Shrunk the physical hitbox of hamsters by 15% to more accurately match their actual visual model size. Note: Because the bounding box is now smaller, you will need to aim slightly more accurately when trying to interact with a hamster.* Patchouli Version** Updated the internal guidebook generation logic to accommodate API breaking changes introduced in Patchouli version 1.21.1-93.You must update Patchouli to the latest version or the game will not launch. Shoulder Animation Configs** Replaced the single Forced Animation State setting with three distinct settings. You can now independently force the Head, Left Shoulder, and Right Shoulder hamsters into specific animation loops (when dynamic animations are disabled).Tree Heist Exits** Hamsters will now perform a small outward jump, launching themselves away from the tree upon successfully completing a Tree Heist. Breeding Cooldown Config** The config setting for breeding cooldown has been changed from Ticks to Seconds to make it significantly easier to manage with the slider.
### Fixed
- Config Live Changes**
- Fixed an issue where changing settings in the
World Gen & Loot config (such as wild bush or hamster spawning settings) required a full game restart to take effect. Saving changes to any config now recalibrates the mod's logic caches on both the client and the server.Visual Rotation Glitch** Attempted to fix an issue where using teleportation mods (like Waystones) or interrupting animations could cause the hamster's model to become permanently rotated backwards or upside down on the client side. I can't be 100% certain about this fix yet, because no one has been able to figure out exactly what causes it and I can't re-create it myself, so let me know if you run into it. Hamster Stretching with Shaders** Fixed a visual bug where hamsters would stretch to extreme sizes during multiplayer server lag or when pausing the game. Dismount Bug** Fixed an issue where holding down the Sneak key for more than a second would cause the OS's auto-key-repeat feature to spam the game with inputs, dismounting all of your shoulder hamsters rapidly. You can now safely hold Sneak without losing your friends. This bug has existed ever since the double-tap setting was added, but I hadn't found it because I usually play with Sneak set to "Toggle" (which means I have no reason to hold it down for extended periods). Memory Optimization** Implemented pre-caching for texture identifiers and simplified rotation math in the render loop to eliminate extra memory objects being generated every frame. Spanish Localization** Some strings in the Hamster Tips guidebook were still outdated (i.e., the Accessories and Sunflower pages). Malformed Recipe** The sliced_cucumber_from_cutting_board.json` recipe for compatibility with Farmers Delight failed to load on 1.20.1 due to a typo.

# The Tactical Fluff & Tree Heist Update
The hamsters were too squishy. This update introduces enchantable armor, a new accessory, and configurable bed respawning. I may have also added a questionable, overengineered method of deforestation, configurable loot injection, farming mechanics, and quality-of-life features while I was at it... and TONS of other stuff. It’s a big one. Brace yourself.
### Added
- Hamster Armor System**
- Acorn Armor:** The biodegradable base tier. Crafted from Acorn Shards and an Acorn Hat. It works like Wolf Armor— completely negating damage until it breaks.
- Tiered Upgrades:** Use the Smithing Table to plate your Acorn Armor with Iron, Gold, Diamond, or Netherite using new **Smithing Templates** found in places where normal smithing templates are usually found.
- Tactical Perks (Configurable):**
- Iron:** Reduces wind resistance, granting extra flight velocity.
- Gold:** Lightweight; grants extra movement speed.
- Diamond:** Shiny; cures kleptomania. Hamsters wearing diamond armor will **fetch** valuables instead of stealing them.
- Netherite:** Dense; grants increased throw inertia and knockback resistance.
- Enchantment Support**
- Hamster Armor can accept **Frost Walker**, **Fire Protection**, **Soul Speed**, **Mending**, and **Unbreaking**.
- Note: Protection, Thorns and Feather Falling are intentionally excluded because hamsters don't take fall damage and Hamster Armor negates 100% of incoming damage until it breaks.*
- Got any ideas for other enchantments that should be supported? Let me know on **[Discord](https://discord.gg/w54mk5bqdf)**.
- Tree Heist Mechanic**
- The Trigger:** Throw your hamster at an Oak Tree (or dismount them while staring at Oak Leaves) to initiate a heist.
- The Simulation Architecture:**
- Intelligent Canopy Mapping Algorithm:** Upon impact, a Gradient Descent Scan locates the trunk anchor. Then a Breadth-First Search utilizes leaf distance gradients to intelligently segment overlapping foliage, allowing the system to isolate and map the specific 3D shape of a single tree, even within a dense forest where the leaves are all touching.
- Proxy Entity:** Your physical hamster is temporarily swapped for an invisible, weightless
TreeSearcherentity. This proxy physically navigates the mapped leaf volume for that specific tree in real-time, randomizing its path to "rummage" for acorns. - Spatial Integrity:** The system verifies the tree's structural integrity every second. If you chop the tree down while a heist is active, the proxy detects the destruction, forces an emergency eject, and your hamster exits.
- Visual & Audio Fidelity:**
- Reactive Foliage:** A deterministically randomized physics simulation makes the leaves physically jiggle and shudder as the proxy moves through them. Each block has a unique oscillation pattern derived from its coordinates, further selling the "scurrying" effect.
- Dynamic Audio:** Sound sources track the invisible proxy's position, meaning you can hear exactly where your hamster is inside the canopy.
- The Economy:** Trees possess persistent "profitability" memory. Over-farming the same coordinates depletes yields until your hamster finds nothing and pouts.
- Lost Hamster Rescue Protocol**
- Added a new quality-of-life feature for wander mode. If a hamster is unable to find a path back to its bed while wandering, simply go to sleep in your own bed.
- When you wake up, any of your stuck hamsters will have "found their way" (teleported) back to their beds and will be sound asleep.
- Requires the hamster to be loaded and the bed to be unoccupied.
- Configurable Action Bar Duration**
- Added a new setting in "UI & Quality of Life" to adjust how long action bar messages stay on screen so now you can actually read them. I couldn't find a mod that did this so I just added it myself. Defaults to 5 seconds (vanilla is 3 seconds), adjustable up to 15 seconds.
- Hamster Tips Guide Book to Custom Creative Tab**
- Registered the guide book item in the Adorable Hamster Pets creative menu group.
- Linked my custom Advancements tree to the Guidebook with a star-shaped button on the landing page.
- Hamster Tips Guidebook Chapters**
- New "Acorn Armor" Entry:** Explains how to throw your pet at a tree for profit, and how to forge nuts into armor.
- New Category/Chapter:** "Loot & Scavenging" – detailing the new loot locations and configurability.
- Acorn Hat Accessory**
- Increases Tree Heist profitability by 2x, yielding more acorns. Fashionable and functional.
- Acorn Shards Ingredient**
- Processed Acorns used to construct the base armor.
- New Inventory Slots**
- Added dedicated **"Bling"** and **"Armor"** slots with interactive UI sounds.
- 10 Advancements**
- "Tree Heist" (Start a Tree Heist)
- "Return on Investnut" (Obtain an Acorn)
- "Ecological Menace" (Exaust a tree's supply)
- "Industrial Nutcracking" (Obtain Acorn Shards).
- "Hardened Salad" (Craft Acorn Armor)
- "Squirrel Cosplay" (Equip Acorn Hat)
- "Expensive Therapy" (Craft Diamond-Plated Acorn Armor)
- "The Immovable Object" (Craft Netherite-Plated Acorn Armor)
- "MURDERER" (Kill a hamster)
- "Rodent Reckoning" (Be killed by a hamster)
- Hamster Bed Respawning**
- Added a configuration toggle (
enableRespawnInBed) to allow hamsters linked to a bed to respawn there upon death. Disabled by default so fit the mod's vanilla-friendly theme. - Respawning hamsters retain their inventory, name, and owner. They may not retain other attributes added by external mods.
- Added tooltips to the Hamster Bed item and Jade overlay indicating if respawn is active.
- Added a new page to the Hamster Bed entry in the Hamster Tips guidebook explaining the feature.
- Dynamic Aerodynamics**
- Hamsters now react to gravity with appropriate drama. The "Flying" animation and dynamic nose-dive rotation logic are no longer exclusive to the Hamster Yeet.
- Any significant fall— whether it's jumping off a ledge or popping out of a tree— will now automatically trigger the flight pose and dynamic pitch rotation (uses smooth cosine interpolation), ensuring they always look like they are falling.
- Global Loot Table Injection**
- Common Loot**
- Items:** Cucumber, Green Bean, and Sunflower **Seeds**.
- Locations:** Villages (Houses, Butchers, Shepherds), Dungeons, Mineshafts, Shipwrecks, Outposts, Small Underwater Ruins, Trial Chamber Supply chests.
- Uncommon Loot**
- Items:** Standard Armor (Acorn, Iron, Gold).
- Locations:** Desert Pyramids, Jungle Temples, Igloos, Ruined Portals, Village Blacksmiths, Large Underwater Ruins.
- High-Tier Loot**
- Items:** Diamond Armor and Basic Upgrade Templates (Iron, Gold). (Also Netherite Armor, if enabled in config).
- Locations:** Nether Fortresses, Bastions, Stronghold Corridors, End Cities, Ancient Cities, Trial Chamber Reward chests.
- Legendary Loot**
- Items:** Accessories (just the Acorn Hat for now) and Advanced Upgrade Templates (Diamond, Netherite).
- Locations:** Woodland Mansions, Buried Treasure, Stronghold Libraries, Ominous Trial Spawners.
- Configuration:**
- Check the **World Gen & Loot** config to adjust the drop chance for every single category listed above, or disable them entirely. Requires a restart to take effect, which is why I put it in the World Gen & Loot config so you can modify it before loading into the world.
- Wild Cheek Pouch Loot**
- Wild hamsters now have a chance (Default 50%, Configurable) to spawn with scavenged items (seeds, nuggets, etc.) in their cheek pouches.
- Context-Aware Scavenging**: Hamsters found in caves have a unique loot pool containing raw ores, glowing berries, and other subterranean treasures. I did not add Diamonds to the list, but you can certainly do that yourself in the config.
- Lopsided Cheeks**: There is a 60% chance the loot will spawn in only one cheek, creating a cute, asymmetrical look.
- Logic**: These items drop on death (also configurable), or persist when tamed— meaning if you tame a wild hamster with full cheeks, you get to keep the loot once you unlock the pouch.
- Configuration**
- The **World Gen & Loot** config includes an "Extra Loot" list. You can define exactly what items wild hamsters spawn with (even items from other mods) and tweak their rarity separately from the default loot list, which is also configurable. Requires a restart to take effect.
- Sunflower Farming**
- Plantable Seeds**:
Sunflower Seedscan now be planted to grow the custom 2-block tall Sunflower. - Bonemeal Duplication**: Right-clicking a fully grown custom Sunflower with Bonemeal now drops a vanilla Sunflower item, matching vanilla tall-flower behavior.
- Head Mount Priority**
- Added a "Mount Priority" setting (
Shoulders FirstvsHead First). - You can now configure hamsters to prioritize the **Head** slot before filling the shoulders, allowing a single hamster to be mounted on the head. It's kind of my new favorite thing to do. I'm even considering making it the default lol. Let me know your thoughts in the **[Discord server](https://discord.gg/w54mk5bqdf)**!
- Gust Volume**
- Added a volume slider for the "Gentle Breeze" sound effect used by Hamster Bedding particles. In some modded environments with mods like **Sound Physics Remastered**, the gust SFX was not loud enough to be audible.
- Configurable Ore Seeking**
- Added new
celebrationOres(Desirable Ores) andsulkingOres(Disappointing Ores) lists to the config. - You can now define exactly which blocks your hamster gets excited about (or disappointed by) using Block IDs or Tags.
- This affects both the Shoulder Hamster Alert and the Independent Seeking behavior.
- Sitting Headshake**
- Added
anim_hamster_sitting_headshakefor when a hamster refuses food while sitting. - The food refusal logic now intelligently selects between sitting, standing, and moving headshake animations.
- Missing Guidebook Warning**
- Added a client-side check that runs 3 minutes after joining a world (configurable).
- If the player is missing the guidebook, a dramatic, clickable chat message appears, offering to open the config screen to reclaim it.
- Includes a solemn oath to read the manual before asking questions in Discord.
- It cannot be disabled. Too many players have come to the Discord asking questions that are answered directly in the guidebook. Upon further investigation, I find they did not get the guidebook and didn't know about it, because the creator of their modpack turned off auto-delivery.
- This warning persists across servers/worlds so it only triggers once per person on single player, and once per person per server on multiplayer (unless reset in config).
- Configurable Wander Interval**
- Added a slider to the Config to control the probability of a hamster deciding to wander.
- Setting this to **0** completely disables idle wandering, useful for keeping them stationary for photos or specific builds.
- For now, this will affect all hamsters. I'll add a specific photo shoot feature later.
- Configurable Look At Player Duration**
- Added a "Look-At Duration" slider to the config.
- Controls how long hamsters stare at you before getting distracted.
- The Math:** Actual duration =
Config Value+Random(0 to 4 seconds). - Example: If set to 60 ticks (3s), they will look for anywhere between 3 and 7 seconds.
- Hamster Riding (Commissioned by [@Saint_Victus](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com))**
- Added a new configuration option: "Enable Hamster Riding" under a new "Commissioned Features" category.
- Adds a keybind (
Ride Hamster, unbound by default) that allows you to mount a hamster. - Dynamic Rider Visuals**
- I hooked into the Geckolib rendering pipeline so players riding a hamster physically attach to the
body_childbone. - This means riders will bob, sway, and rotate in perfect sync with the hamster's running animations instead of floating statically on top.
- Mechanics**
- You can ride *any* hamster (even wild ones), but you can only _control_ hamsters you own (includes jumping!)
- Riding an unowned hamster results in an uncontrolled ride (like a pig without a carrot).
- Riding your own hamster disables its Wander Mode to give you full control.
- Unofficial capacity**
- This commissioned feature doesn't fit the theme of the mod, so this changelog is the only place you'll find it mentioned.
- Legacy Forge Support** (Thanks to [@Konkeeztador](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com)!)
- Added data structures and loading conditions to ensure the mod tags/recipes load correctly on the legacy Forge loader.
- Mod Compatibility Improvements** (Thanks to [@CasualAnimalEnjoyer](https://github.com/CasualAnimalEnjoyer)!)
- Added conventional
ctags for Cheese to improve cross-mod compatibility. - Supplementaries Compatibility**
- Hamsters can now be caught in Cages from the [**Supplementaries**](https://modrinth.com/mod/supplementaries) mod. (Thanks to [**@just_a_cricket**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for the built-in datapack!)
- To enable catching of wild hamsters, go to
config > supplementaries-common.json > functional > cage > require_tamingand turn it off. - Botany Pots Compatibility**
- Added support for [**Botany Pots**](https://modrinth.com/mod/botany-pots). You can now grow Cucumbers, Green Beans, Sunflowers, and the Wild Bushes in pots! (Thanks to [**@CasualAnimalEnjoyer**](https://github.com/CasualAnimalEnjoyer) for the built-in datapack!)
- Hamster Bedding can also be used as a fertilizer in the pots.
- Configurable Biome Tag Exclusion:**
- Added a new
Exclude Biome Tagslist to the World Gen config. By default, this now excludes#minecraft:is_oceanand#minecraft:is_riverto prevent spawns in those biomes regardless of other settings. - Glowing Sunflowers** (Easter Egg)
- Added a rare event where my custom sunflowers will emit light at night, accompanied by magical particles. Rare enough that it is highly unlikely for it to affect multiple sunflowers simultaneously.
- Includes a hidden advancement ("It Can't Be True!") for players who witness the phenomenon up close.
- Configurable via the 'Sunflower Settings' in the World Gen config.
- This is a reference to the Kikoriki cartoon, '[**It Can't Be True**](https://youtu.be/ztwAY6308zY?t=201)' episode, around the 3:22 mark. This feature wasn't really on my agenda, but [**@CasualAnimalEnjoyer**](https://github.com/CasualAnimalEnjoyer) requested it and I added it as a personal thank-you to them for their massive help with mod compatibility and bug fixing.
### Changed
- Animations**
- Updated the crash animation to make it cuter. Now instead of landing flat, the hamster bounces multiple times on its face. Includes sound effects!
- Geckolib Version** ← **UPDATE OR YOUR GAME WILL NOT LAUNCH**
- Updated required Geckolib version from 4.7.3 to 4.8.3 (it was way out of date) to fix animation flickering issues. It may also fix other issues that I had not come across yet— it was literally 10 versions behind lol
- Diamond Stealing AI**
- Refactored the diamond stealing behavior system. Hamsters now intelligently switch between "Theft Mode" (Taunting) and "Delivery Mode" (Presenting) based on the item type and their current equipment. (Configurable)
- Refusal Interactions**
- Attempting to open a locked cheek pouch now triggers the same new intelligent headshake animations (sitting/standing/moving) used for food refusal.
- Item Stealing**
- Hamsters now use their sprinting animation/speed (1.5D) when running towards a diamond to steal it, matching their flee speed. Originally I had them walking at normal speed so as not to alert the player that they were about to steal the diamond, but I changed my mind and I think it's a lot cuter if they sprint over to it.
- Yeet Physics**
- Thrown hamsters now apply **Knockback** to the entities they hit. The force is calculated based on the hamster's velocity, so faster throws = harder hits.
- Pink Petal Accessories**
- Updated rendering to use **3D models** instead of flat texture overlays.
- Petals now have depth and similar positioning on the hamster's head, side, and back.
- Audio Effects**
- Added support for the
hamster_thump_soundkeyframe in the crash animation, triggeringModSounds.HAMSTER_THUMPfor extra dramatic effect. - Wild Bush Textures**
- Thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for giving the textures for Wild Green Bean and Wild Cucumber bushes a fresh new look!
- Dynamic Bed Tooltips**
- The Hamster Bed item and Jade tooltips now dynamically display the names of the configured Lure and Repellent items, ensuring the text matches your config settings.
- Hamster Spawning**:
- Black hamsters now spawn in Lush Caves and Dripstone Caves.
- Update Notifications**
- Migrated the update notification system to pull from the primary source repository, deprecating the legacy public asset repo.
### Fixed
- Biome Spawning Logic**
- Refactored the internal configuration to use custom union tags instead of raw convention tags (e.g.,
adorablehamsterpets:is_caveinstead ofc:is_cave). I had already made my own internal union tags months ago (which point to the Fabric's convention tags for 1.21.1 and Forge tags for 1.20.1), but forgotten to actually point to them in the config. - This fixes a long-standing issue where some hamster variants were not spawning correctly in certain biomes, despite the config saying otherwise. I discovered this when I noticed black hamsters were not spawning in caves, but there were probably other spawn variant issues as well which will now be resolved.
- Guidebook Entry Index Overflow**
- Refactored my custom text-wrapping and pagination mixin logic in the Hamster Tips guidebook index.
- Entry titles in the Entry Index now correctly flow into new pages instead of overflowing off the bottom of the book interface.
- Ore Seeking Logic**
- Fixed a bug where hamsters ignored buried "Disappointing Ores" (Gold) even when configured to make mistakes, due to checking for exposed blocks instead of hidden ones.
- Shoulder Hamster "Mutant" Splitting Glitch**
- Fixed a visual bug on Forge/NeoForge (caused by Oculus/Iris) where shoulder hamsters would visually "split" into two overlapping models causing a z-fighting flicker effect.
- This was caused by the animation controller randomly switching between the two idle animations every frame. They now deterministically pick one based on their personality ID.
- Cheek Pouch Refusal Animation**
- Fixed a bug where the "No" headshake animation wouldn't play when trying to open a locked cheek pouch. (Caused by a mismatch between the animation controller name
stationary_headshakeand the code callingstanding_headshake). - The refusal logic now intelligently selects between sitting, standing, and moving headshakes.
- World Gen Config**
- Some of the groups had "collapsedByDefault" set to "false" which was making it messy.
- Config Issues**
- Fixed a few mistakes in the "Falling Leaf Settings > Static Drift Angle" config tooltip. It now correctly assigns degrees to angles.
- Fixed a bug where configuration options (like "Top Left", "Near", "Single-Press") appeared untranslated in the config screen.
- Sunflower Regrowth**
- Drastically reduced the default time it takes for sunflowers to regrow seeds (Was ~2.8 hours, now ~10 minutes). My original idea was for it to feel like each sunflower gives you one set of seeds, and that's definitely how it felt until now. This change will put it more in line with the rest of Minecraft farming.
- Inventory Label Alignment**
- Updated the Hamster Inventory screen to dynamically center text labels ("Left/Right Cheek", "Bling", "Armor") over their respective slots.
- This ensures proper alignment for languages with text widths different from English.
- Missing Localization**
- Updated Jade HUD tooltips for Hamster Beds to use translatable text for the various boolean states, removing hardcoded English "ENABLED" and "DISABLED" strings.
- Pale Oak Bed Particles**
- Fixed the Pale Oak Hamster Bed missing its block model, which caused missing texture (purple/black) particles when breaking the block. This ensures full visual compatibility if you are using a Pale Garden backport mod on 1.21.1 or 1.20.1.
- Note: there is no Pale Oak Hamster Bed recipe unless you add one with a datapack. I'm running my Data Generator in a 1.21.1 development environment, and the class
Items.PALE_OAK_PLANKSdoes not exist in the code yet, so I cannot reference it in the Java generator to create the recipe. - Fixed Water/Void Spawning:**
- Resolved an issue where hamsters could spawn floating in oceans/rivers or over the void in Skyblock worlds. This was caused by the spawn restriction rules not being registered at the correct time in the mod loading lifecycle, effectively disabling the "valid ground block" check.
- Data Structure & Recipes** (Thanks again [@CasualAnimalEnjoyer](https://github.com/CasualAnimalEnjoyer)!)
- Duplicated tag folders to resolve structural differences between 1.20.1 (plural directories) and 1.21.1 (singular directories).
- Corrected the Cloche and Insolator compatibility recipe paths for 1.20.1.
- Fixed load conditions for Thermal Expansion integration to ensure recipes only load when the mod is present.
- Suffocation**:
- Hamsters now automatically trigger their "self-rescue" teleport logic whenever they start taking suffocation damage, regardless of the cause.
- This resolves issues where hamsters would occasionally take suffocation damage while pouncing on an item. It became more of a problem once the retrieval feature was added since the hamster does not run away from the player.
- Sleeping Hamster Pushability**
- Fixed an issue where hamsters sleeping in beds would become pushable after closing and reopening the world.
- Texture Mipmapping Issue**
- Resized Hamster Bed textures from 35x69 to 64x128 while maintaining their original look. This resolves a rendering issue where non-power-of-two textures forced Minecraft to disable mipmapping, causing all blocks in the game to appear grainy.
- Safe Dismounting**
- Hamsters will no longer agree to dismount directly into lava or water, even if there is a solid block underneath. The safety check now correctly verifies that the space the hamster will occupy is free of hazards.
- Fixed **Biome Detection** (1.20.1)
- Updated internal biome tags to match Minecraft 1.20.1 standards (e.g.,
c:plainsinstead ofc:is_plains). - This resolves issues where hamsters spawned in incorrect biomes (e.g., Gray hamsters in Deserts, Chocolate hamsters in Sunflower Plains) because the game didn't recognize those biomes correctly.
- Invisible Shoulder Hamsters** (1.20.1)
- Fixed an issue where shoulder-mounted hamsters would vanish after traveling to another dimension. (They still existed but only became visible after re-logging).
- Added a forced data sync (only necessary on 1.20.1) to ensure the client immediately recognizes your shoulder hamsters after your player is re-created.
- Item Rendering Visual Glitch** (1.20.1)
- Fixed a visual glitch on 1.20.1 where the hamster's body would turn black when holding an item (e.g., fetching an acorn) by moving item rendering to the post-render phase.

# The Tactical Fluff & Tree Heist Update
The hamsters were too squishy. This update introduces enchantable armor, a new accessory, and configurable bed respawning. I may have also added a questionable, overengineered method of deforestation, configurable loot injection, farming mechanics, and quality-of-life features while I was at it... and TONS of other stuff. It’s a big one. Brace yourself.
### Added
- Hamster Armor System**
- Acorn Armor:** The biodegradable base tier. Crafted from Acorn Shards and an Acorn Hat. It works like Wolf Armor— completely negating damage until it breaks.
- Tiered Upgrades:** Use the Smithing Table to plate your Acorn Armor with Iron, Gold, Diamond, or Netherite using new **Smithing Templates** found in places where normal smithing templates are usually found.
- Tactical Perks (Configurable):**
- Iron:** Reduces wind resistance, granting extra flight velocity.
- Gold:** Lightweight; grants extra movement speed.
- Diamond:** Shiny; cures kleptomania. Hamsters wearing diamond armor will **fetch** valuables instead of stealing them.
- Netherite:** Dense; grants increased throw inertia and knockback resistance.
- Enchantment Support**
- Hamster Armor can accept **Frost Walker**, **Fire Protection**, **Soul Speed**, **Mending**, and **Unbreaking**.
- Note: Protection, Thorns and Feather Falling are intentionally excluded because hamsters don't take fall damage and Hamster Armor negates 100% of incoming damage until it breaks.*
- Got any ideas for other enchantments that should be supported? Let me know on **[Discord](https://discord.gg/w54mk5bqdf)**.
- Tree Heist Mechanic**
- The Trigger:** Throw your hamster at an Oak Tree (or dismount them while staring at Oak Leaves) to initiate a heist.
- The Simulation Architecture:**
- Intelligent Canopy Mapping Algorithm:** Upon impact, a Gradient Descent Scan locates the trunk anchor. Then a Breadth-First Search utilizes leaf distance gradients to intelligently segment overlapping foliage, allowing the system to isolate and map the specific 3D shape of a single tree, even within a dense forest where the leaves are all touching.
- Proxy Entity:** Your physical hamster is temporarily swapped for an invisible, weightless
TreeSearcherentity. This proxy physically navigates the mapped leaf volume for that specific tree in real-time, randomizing its path to "rummage" for acorns. - Spatial Integrity:** The system verifies the tree's structural integrity every second. If you chop the tree down while a heist is active, the proxy detects the destruction, forces an emergency eject, and your hamster exits.
- Visual & Audio Fidelity:**
- Reactive Foliage:** A deterministically randomized physics simulation makes the leaves physically jiggle and shudder as the proxy moves through them. Each block has a unique oscillation pattern derived from its coordinates, further selling the "scurrying" effect.
- Dynamic Audio:** Sound sources track the invisible proxy's position, meaning you can hear exactly where your hamster is inside the canopy.
- The Economy:** Trees possess persistent "profitability" memory. Over-farming the same coordinates depletes yields until your hamster finds nothing and pouts.
- Lost Hamster Rescue Protocol**
- Added a new quality-of-life feature for wander mode. If a hamster is unable to find a path back to its bed while wandering, simply go to sleep in your own bed.
- When you wake up, any of your stuck hamsters will have "found their way" (teleported) back to their beds and will be sound asleep.
- Requires the hamster to be loaded and the bed to be unoccupied.
- Configurable Action Bar Duration**
- Added a new setting in "UI & Quality of Life" to adjust how long action bar messages stay on screen so now you can actually read them. I couldn't find a mod that did this so I just added it myself. Defaults to 5 seconds (vanilla is 3 seconds), adjustable up to 15 seconds.
- Hamster Tips Guide Book to Custom Creative Tab**
- Registered the guide book item in the Adorable Hamster Pets creative menu group.
- Linked my custom Advancements tree to the Guidebook with a star-shaped button on the landing page.
- Hamster Tips Guidebook Chapters**
- New "Acorn Armor" Entry:** Explains how to throw your pet at a tree for profit, and how to forge nuts into armor.
- New Category/Chapter:** "Loot & Scavenging" – detailing the new loot locations and configurability.
- Acorn Hat Accessory**
- Increases Tree Heist profitability by 2x, yielding more acorns. Fashionable and functional.
- Acorn Shards Ingredient**
- Processed Acorns used to construct the base armor.
- New Inventory Slots**
- Added dedicated **"Bling"** and **"Armor"** slots with interactive UI sounds.
- 10 Advancements**
- "Tree Heist" (Start a Tree Heist)
- "Return on Investnut" (Obtain an Acorn)
- "Ecological Menace" (Exaust a tree's supply)
- "Industrial Nutcracking" (Obtain Acorn Shards).
- "Hardened Salad" (Craft Acorn Armor)
- "Squirrel Cosplay" (Equip Acorn Hat)
- "Expensive Therapy" (Craft Diamond-Plated Acorn Armor)
- "The Immovable Object" (Craft Netherite-Plated Acorn Armor)
- "MURDERER" (Kill a hamster)
- "Rodent Reckoning" (Be killed by a hamster)
- Hamster Bed Respawning**
- Added a configuration toggle (
enableRespawnInBed) to allow hamsters linked to a bed to respawn there upon death. Disabled by default so fit the mod's vanilla-friendly theme. - Respawning hamsters retain their inventory, name, and owner. They may not retain other attributes added by external mods.
- Added tooltips to the Hamster Bed item and Jade overlay indicating if respawn is active.
- Added a new page to the Hamster Bed entry in the Hamster Tips guidebook explaining the feature.
- Dynamic Aerodynamics**
- Hamsters now react to gravity with appropriate drama. The "Flying" animation and dynamic nose-dive rotation logic are no longer exclusive to the Hamster Yeet.
- Any significant fall— whether it's jumping off a ledge or popping out of a tree— will now automatically trigger the flight pose and dynamic pitch rotation (uses smooth cosine interpolation), ensuring they always look like they are falling.
- Global Loot Table Injection**
- Common Loot**
- Items:** Cucumber, Green Bean, and Sunflower **Seeds**.
- Locations:** Villages (Houses, Butchers, Shepherds), Dungeons, Mineshafts, Shipwrecks, Outposts, Small Underwater Ruins, Trial Chamber Supply chests.
- Uncommon Loot**
- Items:** Standard Armor (Acorn, Iron, Gold).
- Locations:** Desert Pyramids, Jungle Temples, Igloos, Ruined Portals, Village Blacksmiths, Large Underwater Ruins.
- High-Tier Loot**
- Items:** Diamond Armor and Basic Upgrade Templates (Iron, Gold). (Also Netherite Armor, if enabled in config).
- Locations:** Nether Fortresses, Bastions, Stronghold Corridors, End Cities, Ancient Cities, Trial Chamber Reward chests.
- Legendary Loot**
- Items:** Accessories (just the Acorn Hat for now) and Advanced Upgrade Templates (Diamond, Netherite).
- Locations:** Woodland Mansions, Buried Treasure, Stronghold Libraries, Ominous Trial Spawners.
- Configuration:**
- Check the **World Gen & Loot** config to adjust the drop chance for every single category listed above, or disable them entirely. Requires a restart to take effect, which is why I put it in the World Gen & Loot config so you can modify it before loading into the world.
- Wild Cheek Pouch Loot**
- Wild hamsters now have a chance (Default 50%, Configurable) to spawn with scavenged items (seeds, nuggets, etc.) in their cheek pouches.
- Context-Aware Scavenging**: Hamsters found in caves have a unique loot pool containing raw ores, glowing berries, and other subterranean treasures. I did not add Diamonds to the list, but you can certainly do that yourself in the config.
- Lopsided Cheeks**: There is a 60% chance the loot will spawn in only one cheek, creating a cute, asymmetrical look.
- Logic**: These items drop on death (also configurable), or persist when tamed— meaning if you tame a wild hamster with full cheeks, you get to keep the loot once you unlock the pouch.
- Configuration**
- The **World Gen & Loot** config includes an "Extra Loot" list. You can define exactly what items wild hamsters spawn with (even items from other mods) and tweak their rarity separately from the default loot list, which is also configurable. Requires a restart to take effect.
- Sunflower Farming**
- Plantable Seeds**:
Sunflower Seedscan now be planted to grow the custom 2-block tall Sunflower. - Bonemeal Duplication**: Right-clicking a fully grown custom Sunflower with Bonemeal now drops a vanilla Sunflower item, matching vanilla tall-flower behavior.
- Head Mount Priority**
- Added a "Mount Priority" setting (
Shoulders FirstvsHead First). - You can now configure hamsters to prioritize the **Head** slot before filling the shoulders, allowing a single hamster to be mounted on the head. It's kind of my new favorite thing to do. I'm even considering making it the default lol. Let me know your thoughts in the **[Discord server](https://discord.gg/w54mk5bqdf)**!
- Gust Volume**
- Added a volume slider for the "Gentle Breeze" sound effect used by Hamster Bedding particles. In some modded environments with mods like **Sound Physics Remastered**, the gust SFX was not loud enough to be audible.
- Configurable Ore Seeking**
- Added new
celebrationOres(Desirable Ores) andsulkingOres(Disappointing Ores) lists to the config. - You can now define exactly which blocks your hamster gets excited about (or disappointed by) using Block IDs or Tags.
- This affects both the Shoulder Hamster Alert and the Independent Seeking behavior.
- Sitting Headshake**
- Added
anim_hamster_sitting_headshakefor when a hamster refuses food while sitting. - The food refusal logic now intelligently selects between sitting, standing, and moving headshake animations.
- Missing Guidebook Warning**
- Added a client-side check that runs 3 minutes after joining a world (configurable).
- If the player is missing the guidebook, a dramatic, clickable chat message appears, offering to open the config screen to reclaim it.
- Includes a solemn oath to read the manual before asking questions in Discord.
- It cannot be disabled. Too many players have come to the Discord asking questions that are answered directly in the guidebook. Upon further investigation, I find they did not get the guidebook and didn't know about it, because the creator of their modpack turned off auto-delivery.
- This warning persists across servers/worlds so it only triggers once per person on single player, and once per person per server on multiplayer (unless reset in config).
- Configurable Wander Interval**
- Added a slider to the Config to control the probability of a hamster deciding to wander.
- Setting this to **0** completely disables idle wandering, useful for keeping them stationary for photos or specific builds.
- For now, this will affect all hamsters. I'll add a specific photo shoot feature later.
- Configurable Look At Player Duration**
- Added a "Look-At Duration" slider to the config.
- Controls how long hamsters stare at you before getting distracted.
- The Math:** Actual duration =
Config Value+Random(0 to 4 seconds). - Example: If set to 60 ticks (3s), they will look for anywhere between 3 and 7 seconds.
- Hamster Riding (Commissioned by [@Saint_Victus](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com))**
- Added a new configuration option: "Enable Hamster Riding" under a new "Commissioned Features" category.
- Adds a keybind (
Ride Hamster, unbound by default) that allows you to mount a hamster. - Dynamic Rider Visuals**
- I hooked into the Geckolib rendering pipeline so players riding a hamster physically attach to the
body_childbone. - This means riders will bob, sway, and rotate in perfect sync with the hamster's running animations instead of floating statically on top.
- Mechanics**
- You can ride *any* hamster (even wild ones), but you can only _control_ hamsters you own (includes jumping!)
- Riding an unowned hamster results in an uncontrolled ride (like a pig without a carrot).
- Riding your own hamster disables its Wander Mode to give you full control.
- Unofficial capacity**
- This commissioned feature doesn't fit the theme of the mod, so this changelog is the only place you'll find it mentioned.
- Legacy Forge Support** (Thanks to [@Konkeeztador](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com)!)
- Added data structures and loading conditions to ensure the mod tags/recipes load correctly on the legacy Forge loader.
- Mod Compatibility Improvements** (Thanks to [@CasualAnimalEnjoyer](https://github.com/CasualAnimalEnjoyer)!)
- Added conventional
ctags for Cheese to improve cross-mod compatibility. - Supplementaries Compatibility**
- Hamsters can now be caught in Cages from the [**Supplementaries**](https://modrinth.com/mod/supplementaries) mod. (Thanks to [**@just_a_cricket**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for the built-in datapack!)

- Hamster Bedding can also be used as a fertilizer in the pots.
- Configurable Biome Tag Exclusion:**
- Added a new
Exclude Biome Tagslist to the World Gen config. By default, this now excludes#minecraft:is_oceanand#minecraft:is_riverto prevent spawns in those biomes regardless of other settings. - Glowing Sunflowers** (Easter Egg)
- Added a rare event where my custom sunflowers will emit light at night, accompanied by magical particles. Rare enough that it is highly unlikely for it to affect multiple sunflowers simultaneously.
- Includes a hidden advancement ("It Can't Be True!") for players who witness the phenomenon up close.
- Configurable via the 'Sunflower Settings' in the World Gen config.
- This is a reference to the Kikoriki cartoon, '[**It Can't Be True**](https://youtu.be/ztwAY6308zY?t=201)' episode, around the 3:22 mark.

- Resolved an issue where hamsters could spawn floating in oceans/rivers or over the void in Skyblock worlds. This was caused by the spawn restriction rules not being registered at the correct time in the mod loading lifecycle, effectively disabling the "valid ground block" check.
- Data Structure & Recipes** (Thanks again [@CasualAnimalEnjoyer](https://github.com/CasualAnimalEnjoyer)!)
- Duplicated tag folders to resolve structural differences between 1.20.1 (plural directories) and 1.21.1 (singular directories).
- Corrected the Cloche and Insolator compatibility recipe paths for 1.20.1.
- Fixed load conditions for Thermal Expansion integration to ensure recipes only load when the mod is present.
- Suffocation**:
- Hamsters now automatically trigger their "self-rescue" teleport logic whenever they start taking suffocation damage, regardless of the cause.
- This resolves issues where hamsters would occasionally take suffocation damage while pouncing on an item. It became more of a problem once the retrieval feature was added since the hamster does not run away from the player.
- Sleeping Hamster Pushability**
- Fixed an issue where hamsters sleeping in beds would become pushable after closing and reopening the world.
- Texture Mipmapping Issue**
- Resized Hamster Bed textures from 35x69 to 64x128 while maintaining their original look. This resolves a rendering issue where non-power-of-two textures forced Minecraft to disable mipmapping, causing all blocks in the game to appear grainy.
- Safe Dismounting**
- Hamsters will no longer agree to dismount directly into lava or water, even if there is a solid block underneath. The safety check now correctly verifies that the space the hamster will occupy is free of hazards.
- Fixed **Biome Detection** (1.20.1)
- Updated internal biome tags to match Minecraft 1.20.1 standards (e.g.,
c:plainsinstead ofc:is_plains). - This resolves issues where hamsters spawned in incorrect biomes (e.g., Gray hamsters in Deserts, Chocolate hamsters in Sunflower Plains) because the game didn't recognize those biomes correctly.
- Invisible Shoulder Hamsters** (1.20.1)
- Fixed an issue where shoulder-mounted hamsters would vanish after traveling to another dimension. (They still existed but only became visible after re-logging).
- Added a forced data sync (only necessary on 1.20.1) to ensure the client immediately recognizes your shoulder hamsters after your player is re-created.
- Item Rendering Visual Glitch** (1.20.1)
- Fixed a visual glitch on 1.20.1 where the hamster's body would turn black when holding an item (e.g., fetching an acorn) by moving item rendering to the post-render phase.

# The Tactical Fluff & Tree Heist Update
The hamsters were too squishy. This update introduces enchantable armor, a new accessory, and configurable bed respawning. I may have also added a questionable, overengineered method of deforestation, configurable loot injection, farming mechanics, and quality-of-life features while I was at it... and TONS of other stuff. It’s a big one. Brace yourself.
### Added
- Hamster Armor System**
- Acorn Armor:** The biodegradable base tier. Crafted from Acorn Shards and an Acorn Hat. It works like Wolf Armor— completely negating damage until it breaks.
- Tiered Upgrades:** Use the Smithing Table to plate your Acorn Armor with Iron, Gold, Diamond, or Netherite using new **Smithing Templates** found in places where normal smithing templates are usually found.
- Tactical Perks (Configurable):**
- Iron:** Reduces wind resistance, granting extra flight velocity.
- Gold:** Lightweight; grants extra movement speed.
- Diamond:** Shiny; cures kleptomania. Hamsters wearing diamond armor will **fetch** valuables instead of stealing them.
- Netherite:** Dense; grants increased throw inertia and knockback resistance.
- Enchantment Support**
- Hamster Armor can accept **Frost Walker**, **Fire Protection**, **Soul Speed**, **Mending**, and **Unbreaking**.
- Note: Protection, Thorns and Feather Falling are intentionally excluded because hamsters don't take fall damage and Hamster Armor negates 100% of incoming damage until it breaks.*
- Got any ideas for other enchantments that should be supported? Let me know on **[Discord](https://discord.gg/w54mk5bqdf)**.
- Tree Heist Mechanic**
- The Trigger:** Throw your hamster at an Oak Tree (or dismount them while staring at Oak Leaves) to initiate a heist.
- The Simulation Architecture:**
- Intelligent Canopy Mapping Algorithm:** Upon impact, a Gradient Descent Scan locates the trunk anchor. Then a Breadth-First Search utilizes leaf distance gradients to intelligently segment overlapping foliage, allowing the system to isolate and map the specific 3D shape of a single tree, even within a dense forest where the leaves are all touching.
- Proxy Entity:** Your physical hamster is temporarily swapped for an invisible, weightless
TreeSearcherentity. This proxy physically navigates the mapped leaf volume for that specific tree in real-time, randomizing its path to "rummage" for acorns. - Spatial Integrity:** The system verifies the tree's structural integrity every second. If you chop the tree down while a heist is active, the proxy detects the destruction, forces an emergency eject, and your hamster exits.
- Visual & Audio Fidelity:**
- Reactive Foliage:** A deterministically randomized physics simulation makes the leaves physically jiggle and shudder as the proxy moves through them. Each block has a unique oscillation pattern derived from its coordinates, further selling the "scurrying" effect.
- Dynamic Audio:** Sound sources track the invisible proxy's position, meaning you can hear exactly where your hamster is inside the canopy.
- The Economy:** Trees possess persistent "profitability" memory. Over-farming the same coordinates depletes yields until your hamster finds nothing and pouts.
- Lost Hamster Rescue Protocol**
- Added a new quality-of-life feature for wander mode. If a hamster is unable to find a path back to its bed while wandering, simply go to sleep in your own bed.
- When you wake up, any of your stuck hamsters will have "found their way" (teleported) back to their beds and will be sound asleep.
- Requires the hamster to be loaded and the bed to be unoccupied.
- Configurable Action Bar Duration**
- Added a new setting in "UI & Quality of Life" to adjust how long action bar messages stay on screen so now you can actually read them. I couldn't find a mod that did this so I just added it myself. Defaults to 5 seconds (vanilla is 3 seconds), adjustable up to 15 seconds.
- Hamster Tips Guide Book to Custom Creative Tab**
- Registered the guide book item in the Adorable Hamster Pets creative menu group.
- Linked my custom Advancements tree to the Guidebook with a star-shaped button on the landing page.
- Hamster Tips Guidebook Chapters**
- New "Acorn Armor" Entry:** Explains how to throw your pet at a tree for profit, and how to forge nuts into armor.
- New Category/Chapter:** "Loot & Scavenging" – detailing the new loot locations and configurability.
- Acorn Hat Accessory**
- Increases Tree Heist profitability by 2x, yielding more acorns. Fashionable and functional.
- Acorn Shards Ingredient**
- Processed Acorns used to construct the base armor.
- New Inventory Slots**
- Added dedicated **"Bling"** and **"Armor"** slots with interactive UI sounds.
- 10 Advancements**
- "Tree Heist" (Start a Tree Heist)
- "Return on Investnut" (Obtain an Acorn)
- "Ecological Menace" (Exaust a tree's supply)
- "Industrial Nutcracking" (Obtain Acorn Shards).
- "Hardened Salad" (Craft Acorn Armor)
- "Squirrel Cosplay" (Equip Acorn Hat)
- "Expensive Therapy" (Craft Diamond-Plated Acorn Armor)
- "The Immovable Object" (Craft Netherite-Plated Acorn Armor)
- "MURDERER" (Kill a hamster)
- "Rodent Reckoning" (Be killed by a hamster)
- Hamster Bed Respawning**
- Added a configuration toggle (
enableRespawnInBed) to allow hamsters linked to a bed to respawn there upon death. Disabled by default so fit the mod's vanilla-friendly theme. - Respawning hamsters retain their inventory, name, and owner. They may not retain other attributes added by external mods.
- Added tooltips to the Hamster Bed item and Jade overlay indicating if respawn is active.
- Added a new page to the Hamster Bed entry in the Hamster Tips guidebook explaining the feature.
- Dynamic Aerodynamics**
- Hamsters now react to gravity with appropriate drama. The "Flying" animation and dynamic nose-dive rotation logic are no longer exclusive to the Hamster Yeet.
- Any significant fall— whether it's jumping off a ledge or popping out of a tree— will now automatically trigger the flight pose and dynamic pitch rotation (uses smooth cosine interpolation), ensuring they always look like they are falling.
- Global Loot Table Injection**
- Common Loot**
- Items:** Cucumber, Green Bean, and Sunflower **Seeds**.
- Locations:** Villages (Houses, Butchers, Shepherds), Dungeons, Mineshafts, Shipwrecks, Outposts, Small Underwater Ruins, Trial Chamber Supply chests.
- Uncommon Loot**
- Items:** Standard Armor (Acorn, Iron, Gold).
- Locations:** Desert Pyramids, Jungle Temples, Igloos, Ruined Portals, Village Blacksmiths, Large Underwater Ruins.
- High-Tier Loot**
- Items:** Diamond Armor and Basic Upgrade Templates (Iron, Gold). (Also Netherite Armor, if enabled in config).
- Locations:** Nether Fortresses, Bastions, Stronghold Corridors, End Cities, Ancient Cities, Trial Chamber Reward chests.
- Legendary Loot**
- Items:** Accessories (just the Acorn Hat for now) and Advanced Upgrade Templates (Diamond, Netherite).
- Locations:** Woodland Mansions, Buried Treasure, Stronghold Libraries, Ominous Trial Spawners.
- Configuration:**
- Check the **World Gen & Loot** config to adjust the drop chance for every single category listed above, or disable them entirely. Requires a restart to take effect, which is why I put it in the World Gen & Loot config so you can modify it before loading into the world.
- Wild Cheek Pouch Loot**
- Wild hamsters now have a chance (Default 50%, Configurable) to spawn with scavenged items (seeds, nuggets, etc.) in their cheek pouches.
- Context-Aware Scavenging**: Hamsters found in caves have a unique loot pool containing raw ores, glowing berries, and other subterranean treasures. I did not add Diamonds to the list, but you can certainly do that yourself in the config.
- Lopsided Cheeks**: There is a 60% chance the loot will spawn in only one cheek, creating a cute, asymmetrical look.
- Logic**: These items drop on death (also configurable), or persist when tamed— meaning if you tame a wild hamster with full cheeks, you get to keep the loot once you unlock the pouch.
- Configuration**
- The **World Gen & Loot** config includes an "Extra Loot" list. You can define exactly what items wild hamsters spawn with (even items from other mods) and tweak their rarity separately from the default loot list, which is also configurable. Requires a restart to take effect.
- Sunflower Farming**
- Plantable Seeds**:
Sunflower Seedscan now be planted to grow the custom 2-block tall Sunflower. - Bonemeal Duplication**: Right-clicking a fully grown custom Sunflower with Bonemeal now drops a vanilla Sunflower item, matching vanilla tall-flower behavior.
- Head Mount Priority**
- Added a "Mount Priority" setting (
Shoulders FirstvsHead First). - You can now configure hamsters to prioritize the **Head** slot before filling the shoulders, allowing a single hamster to be mounted on the head. It's kind of my new favorite thing to do. I'm even considering making it the default lol. Let me know your thoughts in the **[Discord server](https://discord.gg/w54mk5bqdf)**!
- Gust Volume**
- Added a volume slider for the "Gentle Breeze" sound effect used by Hamster Bedding particles. In some modded environments with mods like **Sound Physics Remastered**, the gust SFX was not loud enough to be audible.
- Configurable Ore Seeking**
- Added new
celebrationOres(Desirable Ores) andsulkingOres(Disappointing Ores) lists to the config. - You can now define exactly which blocks your hamster gets excited about (or disappointed by) using Block IDs or Tags.
- This affects both the Shoulder Hamster Alert and the Independent Seeking behavior.
- Sitting Headshake**
- Added
anim_hamster_sitting_headshakefor when a hamster refuses food while sitting. - The food refusal logic now intelligently selects between sitting, standing, and moving headshake animations.
- Missing Guidebook Warning**
- Added a client-side check that runs 3 minutes after joining a world (configurable).
- If the player is missing the guidebook, a dramatic, clickable chat message appears, offering to open the config screen to reclaim it.
- Includes a solemn oath to read the manual before asking questions in Discord.
- It cannot be disabled. Too many players have come to the Discord asking questions that are answered directly in the guidebook. Upon further investigation, I find they did not get the guidebook and didn't know about it, because the creator of their modpack turned off auto-delivery.
- This warning persists across servers/worlds so it only triggers once per person on single player, and once per person per server on multiplayer (unless reset in config).
- Configurable Wander Interval**
- Added a slider to the Config to control the probability of a hamster deciding to wander.
- Setting this to **0** completely disables idle wandering, useful for keeping them stationary for photos or specific builds.
- For now, this will affect all hamsters. I'll add a specific photo shoot feature later.
- Configurable Look At Player Duration**
- Added a "Look-At Duration" slider to the config.
- Controls how long hamsters stare at you before getting distracted.
- The Math:** Actual duration =
Config Value+Random(0 to 4 seconds). - Example: If set to 60 ticks (3s), they will look for anywhere between 3 and 7 seconds.
- Hamster Riding (Commissioned by [@Saint_Victus](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com))**
- Added a new configuration option: "Enable Hamster Riding" under a new "Commissioned Features" category.
- Adds a keybind (
Ride Hamster, unbound by default) that allows you to mount a hamster. - Dynamic Rider Visuals**
- I hooked into the Geckolib rendering pipeline so players riding a hamster physically attach to the
body_childbone. - This means riders will bob, sway, and rotate in perfect sync with the hamster's running animations instead of floating statically on top.
- Mechanics**
- You can ride *any* hamster (even wild ones), but you can only _control_ hamsters you own (includes jumping!)
- Riding an unowned hamster results in an uncontrolled ride (like a pig without a carrot).
- Riding your own hamster disables its Wander Mode to give you full control.
- Unofficial capacity**
- This commissioned feature doesn't fit the theme of the mod, so this changelog is the only place you'll find it mentioned.
- Legacy Forge Support** (Thanks to [@Konkeeztador](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com)!)
- Added data structures and loading conditions to ensure the mod tags/recipes load correctly on the legacy Forge loader.
- Mod Compatibility Improvements** (Thanks to [@CasualAnimalEnjoyer](https://github.com/CasualAnimalEnjoyer)!)
- Added conventional
ctags for Cheese to improve cross-mod compatibility. - Supplementaries Compatibility**
- Hamsters can now be caught in Cages from the [**Supplementaries**](https://modrinth.com/mod/supplementaries) mod. (Thanks to [**@just_a_cricket**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for the built-in datapack!)
- To enable catching of wild hamsters, go to
config > supplementaries-common.json > functional > cage > require_tamingand turn it off. - Botany Pots Compatibility**
- Added support for [**Botany Pots**](https://modrinth.com/mod/botany-pots). You can now grow Cucumbers, Green Beans, Sunflowers, and the Wild Bushes in pots! (Thanks to [**@CasualAnimalEnjoyer**](https://github.com/CasualAnimalEnjoyer) for the built-in datapack!)
- Hamster Bedding can also be used as a fertilizer in the pots.
- Configurable Biome Tag Exclusion:**
- Added a new
Exclude Biome Tagslist to the World Gen config. By default, this now excludes#minecraft:is_oceanand#minecraft:is_riverto prevent spawns in those biomes regardless of other settings. - Glowing Sunflowers** (Easter Egg)
- Added a rare event where my custom sunflowers will emit light at night, accompanied by magical particles. Rare enough that it is highly unlikely for it to affect multiple sunflowers simultaneously.
- Includes a hidden advancement ("It Can't Be True!") for players who witness the phenomenon up close.
- Configurable via the 'Sunflower Settings' in the World Gen config.
- This is a reference to the Kikoriki cartoon, '[**It Can't Be True**](https://youtu.be/ztwAY6308zY?t=201)' episode, around the 3:22 mark. This feature wasn't really on my agenda, but [**@CasualAnimalEnjoyer**](https://github.com/CasualAnimalEnjoyer) requested it and I added it as a personal thank-you to them for their massive help with mod compatibility and bug fixing.
### Changed
- Animations**
- Updated the crash animation to make it cuter. Now instead of landing flat, the hamster bounces multiple times on its face. Includes sound effects!
- Geckolib Version** ← **UPDATE OR YOUR GAME WILL NOT LAUNCH**
- Updated required Geckolib version from 4.7.3 to 4.8.3 (it was way out of date) to fix animation flickering issues. It may also fix other issues that I had not come across yet— it was literally 10 versions behind lol
- Diamond Stealing AI**
- Refactored the diamond stealing behavior system. Hamsters now intelligently switch between "Theft Mode" (Taunting) and "Delivery Mode" (Presenting) based on the item type and their current equipment. (Configurable)
- Refusal Interactions**
- Attempting to open a locked cheek pouch now triggers the same new intelligent headshake animations (sitting/standing/moving) used for food refusal.
- Item Stealing**
- Hamsters now use their sprinting animation/speed (1.5D) when running towards a diamond to steal it, matching their flee speed. Originally I had them walking at normal speed so as not to alert the player that they were about to steal the diamond, but I changed my mind and I think it's a lot cuter if they sprint over to it.
- Yeet Physics**
- Thrown hamsters now apply **Knockback** to the entities they hit. The force is calculated based on the hamster's velocity, so faster throws = harder hits.
- Pink Petal Accessories**
- Updated rendering to use **3D models** instead of flat texture overlays.
- Petals now have depth and similar positioning on the hamster's head, side, and back.
- Audio Effects**
- Added support for the
hamster_thump_soundkeyframe in the crash animation, triggeringModSounds.HAMSTER_THUMPfor extra dramatic effect. - Wild Bush Textures**
- Thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for giving the textures for Wild Green Bean and Wild Cucumber bushes a fresh new look!
- Dynamic Bed Tooltips**
- The Hamster Bed item and Jade tooltips now dynamically display the names of the configured Lure and Repellent items, ensuring the text matches your config settings.
- Hamster Spawning**:
- Black hamsters now spawn in Lush Caves and Dripstone Caves.
- Update Notifications**
- Migrated the update notification system to pull from the primary source repository, deprecating the legacy public asset repo.
### Fixed
- Biome Spawning Logic**
- Refactored the internal configuration to use custom union tags instead of raw convention tags (e.g.,
adorablehamsterpets:is_caveinstead ofc:is_cave). I had already made my own internal union tags months ago (which point to the Fabric's convention tags for 1.21.1 and Forge tags for 1.20.1), but forgotten to actually point to them in the config. - This fixes a long-standing issue where some hamster variants were not spawning correctly in certain biomes, despite the config saying otherwise. I discovered this when I noticed black hamsters were not spawning in caves, but there were probably other spawn variant issues as well which will now be resolved.
- Guidebook Entry Index Overflow**
- Refactored my custom text-wrapping and pagination mixin logic in the Hamster Tips guidebook index.
- Entry titles in the Entry Index now correctly flow into new pages instead of overflowing off the bottom of the book interface.
- Ore Seeking Logic**
- Fixed a bug where hamsters ignored buried "Disappointing Ores" (Gold) even when configured to make mistakes, due to checking for exposed blocks instead of hidden ones.
- Shoulder Hamster "Mutant" Splitting Glitch**
- Fixed a visual bug on Forge/NeoForge (caused by Oculus/Iris) where shoulder hamsters would visually "split" into two overlapping models causing a z-fighting flicker effect.
- This was caused by the animation controller randomly switching between the two idle animations every frame. They now deterministically pick one based on their personality ID.
- Cheek Pouch Refusal Animation**
- Fixed a bug where the "No" headshake animation wouldn't play when trying to open a locked cheek pouch. (Caused by a mismatch between the animation controller name
stationary_headshakeand the code callingstanding_headshake). - The refusal logic now intelligently selects between sitting, standing, and moving headshakes.
- World Gen Config**
- Some of the groups had "collapsedByDefault" set to "false" which was making it messy.
- Config Issues**
- Fixed a few mistakes in the "Falling Leaf Settings > Static Drift Angle" config tooltip. It now correctly assigns degrees to angles.
- Fixed a bug where configuration options (like "Top Left", "Near", "Single-Press") appeared untranslated in the config screen.
- Sunflower Regrowth**
- Drastically reduced the default time it takes for sunflowers to regrow seeds (Was ~2.8 hours, now ~10 minutes). My original idea was for it to feel like each sunflower gives you one set of seeds, and that's definitely how it felt until now. This change will put it more in line with the rest of Minecraft farming.
- Inventory Label Alignment**
- Updated the Hamster Inventory screen to dynamically center text labels ("Left/Right Cheek", "Bling", "Armor") over their respective slots.
- This ensures proper alignment for languages with text widths different from English.
- Missing Localization**
- Updated Jade HUD tooltips for Hamster Beds to use translatable text for the various boolean states, removing hardcoded English "ENABLED" and "DISABLED" strings.
- Pale Oak Bed Particles**
- Fixed the Pale Oak Hamster Bed missing its block model, which caused missing texture (purple/black) particles when breaking the block. This ensures full visual compatibility if you are using a Pale Garden backport mod on 1.21.1 or 1.20.1.
- Note: there is no Pale Oak Hamster Bed recipe unless you add one with a datapack. I'm running my Data Generator in a 1.21.1 development environment, and the class
Items.PALE_OAK_PLANKSdoes not exist in the code yet, so I cannot reference it in the Java generator to create the recipe. - Fixed Water/Void Spawning:**
- Resolved an issue where hamsters could spawn floating in oceans/rivers or over the void in Skyblock worlds. This was caused by the spawn restriction rules not being registered at the correct time in the mod loading lifecycle, effectively disabling the "valid ground block" check.
- Data Structure & Recipes** (Thanks again [@CasualAnimalEnjoyer](https://github.com/CasualAnimalEnjoyer)!)
- Duplicated tag folders to resolve structural differences between 1.20.1 (plural directories) and 1.21.1 (singular directories).
- Corrected the Cloche and Insolator compatibility recipe paths for 1.20.1.
- Fixed load conditions for Thermal Expansion integration to ensure recipes only load when the mod is present.
- Suffocation**:
- Hamsters now automatically trigger their "self-rescue" teleport logic whenever they start taking suffocation damage, regardless of the cause.
- This resolves issues where hamsters would occasionally take suffocation damage while pouncing on an item. It became more of a problem once the retrieval feature was added since the hamster does not run away from the player.
- Sleeping Hamster Pushability**
- Fixed an issue where hamsters sleeping in beds would become pushable after closing and reopening the world.
- Texture Mipmapping Issue**
- Resized Hamster Bed textures from 35x69 to 64x128 while maintaining their original look. This resolves a rendering issue where non-power-of-two textures forced Minecraft to disable mipmapping, causing all blocks in the game to appear grainy.
- Safe Dismounting**
- Hamsters will no longer agree to dismount directly into lava or water, even if there is a solid block underneath. The safety check now correctly verifies that the space the hamster will occupy is free of hazards.
- Fixed **Biome Detection** (1.20.1)
- Updated internal biome tags to match Minecraft 1.20.1 standards (e.g.,
c:plainsinstead ofc:is_plains). - This resolves issues where hamsters spawned in incorrect biomes (e.g., Gray hamsters in Deserts, Chocolate hamsters in Sunflower Plains) because the game didn't recognize those biomes correctly.
- Invisible Shoulder Hamsters** (1.20.1)
- Fixed an issue where shoulder-mounted hamsters would vanish after traveling to another dimension. (They still existed but only became visible after re-logging).
- Added a forced data sync (only necessary on 1.20.1) to ensure the client immediately recognizes your shoulder hamsters after your player is re-created.
- Item Rendering Visual Glitch** (1.20.1)
- Fixed a visual glitch on 1.20.1 where the hamster's body would turn black when holding an item (e.g., fetching an acorn) by moving item rendering to the post-render phase.

- Check the **World Gen & Loot** config to adjust the drop chance for every single category listed above, or disable them entirely. Requires a restart to take effect, which is why I put it in the World Gen & Loot config so you can modify it before loading into the world.
- Wild Cheek Pouch Loot**
- Wild hamsters now have a chance (Default 50%, Configurable) to spawn with scavenged items (seeds, nuggets, etc.) in their cheek pouches.
- Context-Aware Scavenging**: Hamsters found in caves have a unique loot pool containing raw ores, glowing berries, and other subterranean treasures. I did not add Diamonds to the list, but you can certainly do that yourself in the config.
- Lopsided Cheeks**: There is a 60% chance the loot will spawn in only one cheek, creating a cute, asymmetrical look.
- Logic**: These items drop on death (also configurable), or persist when tamed— meaning if you tame a wild hamster with full cheeks, you get to keep the loot once you unlock the pouch.
- Configuration**
- The **World Gen & Loot** config includes an "Extra Loot" list. You can define exactly what items wild hamsters spawn with (even items from other mods) and tweak their rarity separately from the default loot list, which is also configurable. Requires a restart to take effect.
- Sunflower Farming**
- Plantable Seeds**:
Sunflower Seedscan now be planted to grow the custom 2-block tall Sunflower. - Bonemeal Duplication**: Right-clicking a fully grown custom Sunflower with Bonemeal now drops a vanilla Sunflower item, matching vanilla tall-flower behavior.
- Head Mount Priority**
- Added a "Mount Priority" setting (
Shoulders FirstvsHead First). - You can now configure hamsters to prioritize the **Head** slot before filling the shoulders, allowing a single hamster to be mounted on the head. It's kind of my new favorite thing to do. I'm even considering making it the default lol. Let me know your thoughts in the **[Discord server](https://discord.gg/w54mk5bqdf)**!
- Gust Volume**
- Added a volume slider for the "Gentle Breeze" sound effect used by Hamster Bedding particles. In some modded environments with mods like **Sound Physics Remastered**, the gust SFX was not loud enough to be audible.
- Configurable Ore Seeking**
- Added new
celebrationOres(Desirable Ores) andsulkingOres(Disappointing Ores) lists to the config. - You can now define exactly which blocks your hamster gets excited about (or disappointed by) using Block IDs or Tags.
- This affects both the Shoulder Hamster Alert and the Independent Seeking behavior.
- Sitting Headshake**
- Added
anim_hamster_sitting_headshakefor when a hamster refuses food while sitting. - The food refusal logic now intelligently selects between sitting, standing, and moving headshake animations.
- Missing Guidebook Warning**
- Added a client-side check that runs 3 minutes after joining a world (configurable).
- If the player is missing the guidebook, a dramatic, clickable chat message appears, offering to open the config screen to reclaim it.
- Includes a solemn oath to read the manual before asking questions in Discord.
- It cannot be disabled. Too many players have come to the Discord asking questions that are answered directly in the guidebook. Upon further investigation, I find they did not get the guidebook and didn't know about it, because the creator of their modpack turned off auto-delivery.
- This warning persists across servers/worlds so it only triggers once per person on single player, and once per person per server on multiplayer (unless reset in config).
- Configurable Wander Interval**
- Added a slider to the Config to control the probability of a hamster deciding to wander.
- Setting this to **0** completely disables idle wandering, useful for keeping them stationary for photos or specific builds.
- For now, this will affect all hamsters. I'll add a specific photo shoot feature later.
- Configurable Look At Player Duration**
- Added a "Look-At Duration" slider to the config.
- Controls how long hamsters stare at you before getting distracted.
- The Math:** Actual duration =
Config Value+Random(0 to 4 seconds). - Example: If set to 60 ticks (3s), they will look for anywhere between 3 and 7 seconds.
- Hamster Riding (Commissioned by [@Saint_Victus](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com))**
- Added a new configuration option: "Enable Hamster Riding" under a new "Commissioned Features" category.
- Adds a keybind (
Ride Hamster, unbound by default) that allows you to mount a hamster. - Dynamic Rider Visuals**
- I hooked into the Geckolib rendering pipeline so players riding a hamster physically attach to the
body_childbone. - This means riders will bob, sway, and rotate in perfect sync with the hamster's running animations instead of floating statically on top.
- Mechanics**
- You can ride *any* hamster (even wild ones), but you can only _control_ hamsters you own (includes jumping!)
- Riding an unowned hamster results in an uncontrolled ride (like a pig without a carrot).
- Riding your own hamster disables its Wander Mode to give you full control.
- Unofficial capacity**
- This commissioned feature doesn't fit the theme of the mod, so this changelog is the only place you'll find it mentioned.
- Legacy Forge Support** (Thanks to [@Konkeeztador](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com)!)
- Added data structures and loading conditions to ensure the mod tags/recipes load correctly on the legacy Forge loader.
- Mod Compatibility Improvements** (Thanks to [@CasualAnimalEnjoyer](https://github.com/CasualAnimalEnjoyer)!)
- Added conventional
ctags for Cheese to improve cross-mod compatibility. - Supplementaries Compatibility**
- Hamsters can now be caught in Cages from the [**Supplementaries**](https://modrinth.com/mod/supplementaries) mod. (Thanks to [**@just_a_cricket**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for the built-in datapack!)
- To enable catching of wild hamsters, go to
config > supplementaries-common.json > functional > cage > require_tamingand turn it off. - Botany Pots Compatibility**
- Added support for [**Botany Pots**](https://modrinth.com/mod/botany-pots). You can now grow Cucumbers, Green Beans, Sunflowers, and the Wild Bushes in pots! (Thanks to [**@CasualAnimalEnjoyer**](https://github.com/CasualAnimalEnjoyer) for the built-in datapack!)
- Hamster Bedding can also be used as a fertilizer in the pots.
- Configurable Biome Tag Exclusion:**
- Added a new
Exclude Biome Tagslist to the World Gen config. By default, this now excludes#minecraft:is_oceanand#minecraft:is_riverto prevent spawns in those biomes regardless of other settings. - Glowing Sunflowers** (Easter Egg)
- Added a rare event where my custom sunflowers will emit light at night, accompanied by magical particles. Rare enough that it is highly unlikely for it to affect multiple sunflowers simultaneously.
- Includes a hidden advancement ("It Can't Be True!") for players who witness the phenomenon up close.
- Configurable via the 'Sunflower Settings' in the World Gen config.
- This is a reference to the Kikoriki cartoon, '[**It Can't Be True**](https://youtu.be/ztwAY6308zY?t=201)' episode, around the 3:22 mark. This feature wasn't really on my agenda, but [**@CasualAnimalEnjoyer**](https://github.com/CasualAnimalEnjoyer) requested it and I added it as a personal thank-you to them for their massive help with mod compatibility and bug fixing.
### Changed
- Animations**
- Updated the crash animation to make it cuter. Now instead of landing flat, the hamster bounces multiple times on its face. Includes sound effects!
- Geckolib Version** ← **UPDATE OR YOUR GAME WILL NOT LAUNCH**
- Updated required Geckolib version from 4.7.3 to 4.8.3 (it was way out of date) to fix animation flickering issues. It may also fix other issues that I had not come across yet— it was literally 10 versions behind lol
- Diamond Stealing AI**
- Refactored the diamond stealing behavior system. Hamsters now intelligently switch between "Theft Mode" (Taunting) and "Delivery Mode" (Presenting) based on the item type and their current equipment. (Configurable)
- Refusal Interactions**
- Attempting to open a locked cheek pouch now triggers the same new intelligent headshake animations (sitting/standing/moving) used for food refusal.
- Item Stealing**
- Hamsters now use their sprinting animation/speed (1.5D) when running towards a diamond to steal it, matching their flee speed. Originally I had them walking at normal speed so as not to alert the player that they were about to steal the diamond, but I changed my mind and I think it's a lot cuter if they sprint over to it.
- Yeet Physics**
- Thrown hamsters now apply **Knockback** to the entities they hit. The force is calculated based on the hamster's velocity, so faster throws = harder hits.
- Pink Petal Accessories**
- Updated rendering to use **3D models** instead of flat texture overlays.
- Petals now have depth and similar positioning on the hamster's head, side, and back.
- Audio Effects**
- Added support for the
hamster_thump_soundkeyframe in the crash animation, triggeringModSounds.HAMSTER_THUMPfor extra dramatic effect. - Wild Bush Textures**
- Thanks to [**@jimcerberus**](https://this_person_did_not_want_to_include_a_link_but_I_wanted_their_name_to_be_blue.com) for giving the textures for Wild Green Bean and Wild Cucumber bushes a fresh new look!
- Dynamic Bed Tooltips**
- The Hamster Bed item and Jade tooltips now dynamically display the names of the configured Lure and Repellent items, ensuring the text matches your config settings.
- Hamster Spawning**:
- Black hamsters now spawn in Lush Caves and Dripstone Caves.
- Update Notifications**
- Migrated the update notification system to pull from the primary source repository, deprecating the legacy public asset repo.
### Fixed
- Biome Spawning Logic**
- Refactored the internal configuration to use custom union tags instead of raw convention tags (e.g.,
adorablehamsterpets:is_caveinstead ofc:is_cave). I had already made my own internal union tags months ago (which point to the Fabric's convention tags for 1.21.1 and Forge tags for 1.20.1), but forgotten to actually point to them in the config. - This fixes a long-standing issue where some hamster variants were not spawning correctly in certain biomes, despite the config saying otherwise. I discovered this when I noticed black hamsters were not spawning in caves, but there were probably other spawn variant issues as well which will now be resolved.
- Guidebook Entry Index Overflow**
- Refactored my custom text-wrapping and pagination mixin logic in the Hamster Tips guidebook index.
- Entry titles in the Entry Index now correctly flow into new pages instead of overflowing off the bottom of the book interface.
- Ore Seeking Logic**
- Fixed a bug where hamsters ignored buried "Disappointing Ores" (Gold) even when configured to make mistakes, due to checking for exposed blocks instead of hidden ones.
- Shoulder Hamster "Mutant" Splitting Glitch**
- Fixed a visual bug on Forge/NeoForge (caused by Oculus/Iris) where shoulder hamsters would visually "split" into two overlapping models causing a z-fighting flicker effect.
- This was caused by the animation controller randomly switching between the two idle animations every frame. They now deterministically pick one based on their personality ID.
- Cheek Pouch Refusal Animation**
- Fixed a bug where the "No" headshake animation wouldn't play when trying to open a locked cheek pouch. (Caused by a mismatch between the animation controller name
stationary_headshakeand the code callingstanding_headshake). - The refusal logic now intelligently selects between sitting, standing, and moving headshakes.
- World Gen Config**
- Some of the groups had "collapsedByDefault" set to "false" which was making it messy.
- Config Issues**
- Fixed a few mistakes in the "Falling Leaf Settings > Static Drift Angle" config tooltip. It now correctly assigns degrees to angles.
- Fixed a bug where configuration options (like "Top Left", "Near", "Single-Press") appeared untranslated in the config screen.
- Sunflower Regrowth**
- Drastically reduced the default time it takes for sunflowers to regrow seeds (Was ~2.8 hours, now ~10 minutes). My original idea was for it to feel like each sunflower gives you one set of seeds, and that's definitely how it felt until now. This change will put it more in line with the rest of Minecraft farming.
- Inventory Label Alignment**
- Updated the Hamster Inventory screen to dynamically center text labels ("Left/Right Cheek", "Bling", "Armor") over their respective slots.
- This ensures proper alignment for languages with text widths different from English.
- Missing Localization**
- Updated Jade HUD tooltips for Hamster Beds to use translatable text for the various boolean states, removing hardcoded English "ENABLED" and "DISABLED" strings.
- Pale Oak Bed Particles**
- Fixed the Pale Oak Hamster Bed missing its block model, which caused missing texture (purple/black) particles when breaking the block. This ensures full visual compatibility if you are using a Pale Garden backport mod on 1.21.1 or 1.20.1.
- Note: there is no Pale Oak Hamster Bed recipe unless you add one with a datapack. I'm running my Data Generator in a 1.21.1 development environment, and the class
Items.PALE_OAK_PLANKSdoes not exist in the code yet, so I cannot reference it in the Java generator to create the recipe. - Fixed Water/Void Spawning:**
- Resolved an issue where hamsters could spawn floating in oceans/rivers or over the void in Skyblock worlds. This was caused by the spawn restriction rules not being registered at the correct time in the mod loading lifecycle, effectively disabling the "valid ground block" check.
- Data Structure & Recipes** (Thanks again [@CasualAnimalEnjoyer](https://github.com/CasualAnimalEnjoyer)!)
- Duplicated tag folders to resolve structural differences between 1.20.1 (plural directories) and 1.21.1 (singular directories).
- Corrected the Cloche and Insolator compatibility recipe paths for 1.20.1.
- Fixed load conditions for Thermal Expansion integration to ensure recipes only load when the mod is present.
- Suffocation**:
- Hamsters now automatically trigger their "self-rescue" teleport logic whenever they start taking suffocation damage, regardless of the cause.
- This resolves issues where hamsters would occasionally take suffocation damage while pouncing on an item. It became more of a problem once the retrieval feature was added since the hamster does not run away from the player.
- Sleeping Hamster Pushability**
- Fixed an issue where hamsters sleeping in beds would become pushable after closing and reopening the world.
- Texture Mipmapping Issue**
- Resized Hamster Bed textures from 35x69 to 64x128 while maintaining their original look. This resolves a rendering issue where non-power-of-two textures forced Minecraft to disable mipmapping, causing all blocks in the game to appear grainy.
- Safe Dismounting**
- Hamsters will no longer agree to dismount directly into lava or water, even if there is a solid block underneath. The safety check now correctly verifies that the space the hamster will occupy is free of hazards.
- Fixed **Biome Detection** (1.20.1)
- Updated internal biome tags to match Minecraft 1.20.1 standards (e.g.,
c:plainsinstead ofc:is_plains). - This resolves issues where hamsters spawned in incorrect biomes (e.g., Gray hamsters in Deserts, Chocolate hamsters in Sunflower Plains) because the game didn't recognize those biomes correctly.
- Invisible Shoulder Hamsters** (1.20.1)
- Fixed an issue where shoulder-mounted hamsters would vanish after traveling to another dimension. (They still existed but only became visible after re-logging).
- Added a forced data sync (only necessary on 1.20.1) to ensure the client immediately recognizes your shoulder hamsters after your player is re-created.
- Item Rendering Visual Glitch** (1.20.1)
- Fixed a visual glitch on 1.20.1 where the hamster's body would turn black when holding an item (e.g., fetching an acorn) by moving item rendering to the post-render phase.

# **The Slap My Forehead Patch**
⚠️ NOTE: If you are playing on 1.21.1, you do not technically need this, unless you're seeing dozens of hamsters on your shoulder. Go have a snack.
### Fixed
#### 1.20.1
- Server Crash: "Unknown Message Type" (The 'I misunderstood how old Architectury works' bug)**
- The Issue:** On dedicated 1.20.1 servers, the game would crash immediately upon trying to sync hamster data.
- The Cause:** I (sort of) copy-pasted the shiny, modern Architectury networking code from 1.21.1 into the 1.20.1 backport. Turns out, the older Architectury API requires you to introduce packets to the server politely before sending them. The server received the hamster data, said "I don't know her," and panicked.
- The Fix:** Refactored the network registration to actually work on 1.20.1.
- Also, I have left several aggressively capitalized comments in the source code warning my future self that 1.20.1 Architectury networking is different. So hopefully this will never happen again!
- "Mutant Hamster Pile" Cleanup**
- The Issue:** Players affected by the previous Invalid Player Data bug might have ended up with "ghost" hamster data, resulting in dozens of duplicate hamsters appearing on their shoulder.
- The Fix:** Spamming your dismount button should fix the issue, but not everyone reads changelogs so I added an auto-sanitizer that runs on login. It will instantly detect and delete any ghost/duplicate hamster entries, returning your character to normal without you needing to do anything.

# **The Tiny Patch**
This patch is hamster-sized, but fixes a pretty big issue. In my zeal to make my code more defensive against Macaw's Mods on Sunday, I accidentally created a bug that locked players out of worlds if they logged out with a shoulder hamster. That is now fixed. Your worlds are safe, and you can log in again. I also squeezed in Xaero's Minimap support and a few other things while I was at it.
### Added
- New Translations**
- Added 6 new locals for the Spanish translation thanks to [@The Retro Stitcher](https://theretrostitcher.com/).
- Xaero's Minimap Compatibility**
- Thanks to help from [@Kazerio](https://modrinth.com/user/kazerio), added hamster icons to Xaero's Minimap!
### Fixed
- Invalid Player Data / World Join Crash**
- Resolved a critical issue where the game would crash or lock players out of worlds if they had a hamster on their shoulder. This was accidentally introduced in version 3.4.1 when I refactored the code to defend against the network protocol error caused by Macaw's Mods.
- I had accidentally introduced a race condition where the mod attempted to sync pet data before the player's network connection was fully established. If you had previously been locked out of any of your worlds due to this bug, you should now be able to join just fine and your hamsters will still be on your shoulder.
- Config Screen Localization**
- Implemented a work-around for an issue where the "Main Settings" and "World Gen Settings" descriptions were not translatable due to a known bug with Fzzy Config.
- Fixed untranslated enum values (e.g., "Near/Medium/Far", "Sneak Key") in dropdown menus.
- Fixed untranslated conditional help text (e.g., "Only available when...").
- EMI Compatibility**
- Resolved tooltip mod name duplication when EMI is installed.

# **The Edge Case Extravaganza Patch**
This patch is dedicated to the 1% of you running modpacks complicated enough to break the space-time continuum. If you weren't crashing, you probably won't notice a difference. If you *were* crashing because you threw a hamster at a target more than 16 blocks away while running Shaders and Macaw's Furniture on NeoForge... your problems are solved!
### Added
- Translations**
- Updated langage files with a few translated strings that Crowdin elected to omit from the last version!
- Major overhaul to the Russian translation of the Hamster Tips guidebook to ensure the text fits better on the pages, thanks to [@CasualAnimalEnjoyer](https://github.com/CasualAnimalEnjoyer)!
### Changed
- Mod Icon**
- As all true geniuses do, [@The Retro Stitcher](https://theretrostitcher.com/) woke up in a cold sweat with ideas for improving the mod's icon even further. JK about the cold sweat part. His improvements have been implemented. Thanks again!
- The mod's
README.mdfile (also known as the "landing page") has had a major overhaul!** - Used the Flashback mod to render epic GIFs showing off almost every feature.

# **The Cuteness Overhaul Update**
## Beds, wander mode, new animations, suspiciously advanced leaf physics, and more!
Give your tamed hamsters an actual home with the new Hamster Bed, Wander Mode, and cozy bedding that doubles as a tiny leaf particle generator. Yeeted hamsters are now cuter, more terrifying, and broadcast their sound effects farther, so your friends can fully appreciate incoming fur missiles. Added new animations, updated some existing ones. Under the hood, variant spawning is now fully biome-configurable and a pile of long-suffering bugs—ghost shoulder hamsters, startup crashes, and more—have finally been escorted off the premises.
### Added
- Fully Configurable Biome-Based Variant Spawning System**
- The logic determining which hamster color variants spawn in which biomes is no longer hardcoded.
- It is now entirely driven by new settings in the config file under
Spawn Settings > Variant Spawning by Biome. - Users can now define custom lists of biome IDs, biome tags (including
c:convention tags), and exclusion lists for each of the seven main color variants/biome groups (Blue, Lavender, White, Gray, Black, Cream, and Chocolate). - This provides significantly greater compatibility with world-generation mods like Terralith and Biomes O' Plenty, allowing users to fine-tune hamster diversity in any modded environment. The default values have been set to preserve the existing spawning behavior that was present already.
- The Orange variant acts as the default fallback and will spawn in any biome where hamsters are allowed that does not meet the criteria for the other configured colors. That's why it does not have its own set of biome lists in the config.
- Hamster Yeet Audio Overhaul & Visual Enhancement**
- Completely re-worked the
hamster_flyinganimation. It's now much cuter. Not that you'll ever see it, unless of course you record yourself throwing the hamster with the Flashback mod. Hint hint. It's quite fun. - Re-designed the
hamster_throwsound so you can hear the hamster's ears flapping in the wind, which is part of the updated animation. - The throw sound now plays directly at the thrower's location, ensuring the full baked-in Doppler effect is heard instead of cutting off abruptly as the hamster flies outside Minecraft's 16-block sound attenuation cutoff.
- Added a new predictive "incoming" sound effect (reverse Doppler) that plays at the target's location, giving victims a one-second audible warning before impact.
- Thrown hamsters now dynamically rotate their pitch to match their flight trajectory (nosing up when ascending, down when falling) instead of remaining perfectly horizontal like a frisbee.
- Implemented a custom sound broadcasting system for long-range throws. Players between 16 and 50 blocks away (who would normally hear silence due to vanilla limits) will now hear a faint impact sound, which dynamically adjusts its volume and changes type depending on whether the hamster impacted a block or an entity. Similar to the old logic, but now you'll actually hear something if you're trying to throw a 50-yard pass.
- New Block: The Hamster Bed**
- Introducing the Hamster Bed, a new block that serves as an anchor point for the new feature, **Tamed Wander Mode**.
- Craftable with a new "Hamster Bedding" item and wood planks. It comes in all nine vanilla wood variants (Oak, Spruce, Birch, Jungle, Acacia, Dark Oak, Mangrove, Cherry, and Bamboo).
- A tamed hamster can be linked to a bed by right-clicking it with the bed item in hand. The bed item will then store the hamster's data. Placing the linked bed in the world activates Wander Mode for that hamster.
- Placing the bed while targeting the underside of a block places it upside-down, triggers a new advancement, disables the bed's sleep function until it is broken, and begins to spawn floaty, cozy leaf particles. More on that in a sec.
- New Item: Hamster Bedding**
- Added "Hamster Bedding," a new crafting component for the Hamster Bed, made from a cozy blend of leaves, podzol, and dead bushes. _(The leaves will be replaced with **Leaf Litter** when I port the mod to 1.21.5, giving them a fun purpose)._
- Beyond its use in crafting, this item can be used by hand or from a Dispenser to release a decorative cloud of leaf particles, perfect for adding a touch of autumnal ambiance to your life.
- Advanced Particle Physics System for Bedding**
- The new leaf particles are driven by a custom client-side physics simulation with two distinct behavioral models.
- Particles spawned from bed interactions use a standard gravity-and-friction model for a simple settling effect.
- Particles spawned from an upside down Hamster Bed, the Hamster Bedding item or a dispenser use a "floaty" physics model, featuring a gentle pendulum-like sway based on sinusoidal motion.
- This floaty mode includes a deterministic, spatially-coherent wind gust simulation. It uses a grid-based hashing function to ensure particles in the same area react to the same pseudo-random wind events, creating synchronized, emergent behavior.
- New Intelligent Indoor/Outdoor Detection Algorithm for Particles**
- Implemented a custom algorithm to prevent the wind gusts from the particle system from having an effect on particles that are "indoors."
- The system analyzes three environmental factors in real-time: skylight levels, vertical roof clearance, and horizontal openness (i.e., proximity to open doorways or windows).
- It uses a high-performance caching system to minimize performance impact and employs hysteresis to prevent visual flickering when particles are near the threshold between an indoor and outdoor space.
- New Feature: Tamed Wander Mode**
- Tamed hamsters can now be set to "Wander Mode," allowing them to roam freely within a configurable radius of their linked bed instead of constantly following the player.
- Activation:** Link a Hamster Bed item to a hamster, then place it in the world.
- Control:** Right-click the placed bed to toggle Wander Mode on or off for the linked hamster. Sneak + right-click to cycle through three wander distances (Near, Medium, Far), which are configurable.
- Hamsters in Wander Mode will automatically seek out their bed to sleep based on the time of day (or the "Circadian Chaos" random timer) if enabled in the config.
- Added "The Great Escape" Guide Book Entry:**
- Details the crafting and use of the new Hamster Bed and Hamster Bedding items, featuring custom artwork.
- Explains how to link a bed to a hamster to enable "Tamed Wander Mode."
- Outlines all interactions for configuring wander distance, luring to bed, and unlinking.
- New Animations and Sounds for Sit/Stand/Sleep**
- Added new animations for sitting down, standing up, and waking from sleep.
- Added new
hamster_swishandhamster_thumpsound effects that play during these transitions, making interactions feel more realistic and fun. - New Dispenser Behavior for Hamster Bedding**
- Dispensers can now be loaded with Hamster Bedding. When activated, they will shoot out a decorative puff of the new floaty leaf particles, consuming one Hamster Bedding item.
- New Advancements for Wander Mode and Crafting**
- Added a new branch to the "The Hamster Life" advancement tab to guide players through the new features.
- New advancements include: "Artisanal Floor Mulch" (crafting bedding), "Luxury Leaf Pile" (crafting a bed), "Home is Where the Leaves Are" (linking a bed), "Sweet Dreams 'r Made of Leaves" (hamster sleeping in a bed), and a hidden challenge advancement for placing a bed upside-down.
- New Jade Integration for Hamster Bed**
- If the Jade mod is installed, looking at a Hamster Bed will now display a detailed tooltip.
- It shows which hamster the bed is linked to, whether Wander Mode is active, the current wander distance, and whether the hamster is allowed to sleep in the bed. Sneaking reveals detailed instructions on how to control the bed's functions.
- Added Compatibility for Croptopia, Immersive Engineering, Serene Seasons, and Thermal Expansion**
- A huge thank you to [@CasualAnimalEnjoyer](https://github.com/CasualAnimalEnjoyer) for creating 30 new resource files to ensure out-of-the-box compatibility.
- Croptopia:** Food recipes now accept AHP vegetables via tags. Seed crafting recipes have been separated to ensure crafting an AHP vegetable yields an AHP seed, preventing conflicts with Croptopia's own seed recipes.
- Serene Seasons:** Cucumber and Green Bean crops now have defined growing seasons and will bloom accordingly.
- Tech Mods:** Added support for growing Cucumber and Green Bean crops in the **Immersive Engineering** Garden Cloche and the **Thermal Expansion** Phytogenic Insolator.
- New Mod Icon**
- Huge thanks to [@The Retro Stitcher](https://theretrostitcher.com/) for re-designing the mod's icon!
### Changed
- Announcement icon position in Creative Inventory**
- The announcement bell icon that appears in the Creative Inventory screen has been moved from the bottom-right corner to the top-right corner of the screen.
- This relocation prevents the icon from being overlapped by popular inventory utility mods such as JEI, REI, and EMI.
- The maximum configurable X/Y offsets for the creative inventory widget have also been increased from 100 to 500 to allow for greater user customization.
- Improved the "Settle to Sleep" Animations**
- Tweaked the "Settle to Sleep" Animations to make them considerably cuter and more compatible with scenarios where the hamster might be "jumping into bed."
- Smarter Hamster Pathfinding (Bed Avoidance)**
- Hamsters now have a custom navigation system that makes them aware of Hamster Beds.
- By default, a hamster will now attempt to pathfind *around* any Hamster Bed that is not its own linked bed. After all, hamsters can be a bit territorial irl.
- To prevent hamsters from getting stuck in complex environments, they will only try a few alternate routes before giving up and taking a more direct path. This avoidance behavior can be disabled in the config.
### Fixed
- Personality ID assignment for command-spawned hamsters**
- Resolved an issue where hamsters created using the
/summoncommand were not being assigned a random "personality ID," causing them all to use the same animations and sitting poses. - This was caused by the
/summoncommand bypassing theinitialize()method where the ID was being set. - Orange hamster spawning in Stony Shore biomes**
- Fixed a bug where orange hamsters were incorrectly spawning in the
minecraft:stony_shorebiome instead of the intended light/dark gray variants. - The biome was being correctly excluded from the "white" variant spawn list but did not match any other specific criteria, causing it to fall back to the default orange variant. The spawn conditions for gray hamsters now explicitly include this biome.
- Startup crash (
StackOverflowError) related to the announcement system** - Fixed a critical
StackOverflowErrorcrash that would occur on game launch if the "Snooze (Session)" feature had been used in the previous session. - The crash was caused by a recursive loop in the
AnnouncementManager's initialization logic. The redundant check causing the loop has been removed. - "Snooze (Session)" functionality and state synchronization with Patchouli**
- The "Snooze (Session)" button now correctly snoozes only the specific announcement being viewed, rather than incorrectly disabling all notifications globally for the session.
- The underlying
disabled_until_launchsystem, which was the source of the startup crash, has been completely removed and replaced with a non-persistent, in-memory list for session-snoozed items. - Fixed a bug where announcements snoozed for the session would remain marked as "read" in the Patchouli guide book after restarting the game. The system now correctly syncs the "unread" status of all pending notifications with Patchouli's data when a world is loaded.
- Ghost Shoulder Hamsters on Player Death**
- Resolved a critical bug where shoulder-mounted hamsters would remain on the player after death, becoming permanently stuck. They will now correctly spawn at the player's death location in a 'knocked out' state, and a new config option allows players to keep them on their shoulder upon respawn if desired.
- Implemented a backward-compatibility fix to ensure any hamsters that were previously stuck on a player's shoulder can now be dismounted correctly.
- Stale triggerable animations playing when entity is rendered**
- Fixed a visual desynchronization where a one-shot animation (like the "Settle to Sleep" transition) triggered while a hamster was off-screen would play belatedly as soon as the hamster was rendered, causing it to be out of sync with the new sound effects.
- A server-side cancellation scheduler now ensures that any triggered animation automatically expires if it has not been played by a client within its expected duration.
- Hamster and wild bush spawning on Sculk, Clay, and Moss blocks**
- Black hamsters can now correctly spawn on Sculk blocks, decreasing their unintentional rareness in the Deep Dark biome.
- Wild Green Bean and Wild Cucumber bushes can now generate on Clay and Moss blocks, allowing them to spawn more frequently in biomes like Swamps, especially if you have a mod that modifies the block palette of the ground in those areas.
- Resolved "Unknown message ID" errors on dedicated servers (1.20.1)**
- Split the 1.20.1 network packet registration into distinct client-to-server and server-to-client methods. (This had already been done on 1.21.1)
- Ensured that the server correctly registers handlers for client packets (like render state updates), preventing disconnects or log errors when players interact with hamsters.
- Corrected Gray Hamster spawning in deserts.**
- Gray hamsters were incorrectly spawning in sandy biomes like deserts, where Cream hamsters are intended to appear.
- Added the
c:is_sandytag to the Gray variant's exclusion list to prevent this overlap. - Note:** If you're still seeing Gray hamsters in deserts, navigate to
Spawn Settings > Variant Spawning > Gray Variants > Excluded Tagsin the config menu, right-click the setting, and select "Restore Defaults." - Fixed Uninteractable Hamsters with Force-Mount Keybind**
- Resolved a critical bug where enabling the "Force Shoulder Mount" keybind in the config would prevent all interactions with tamed hamsters.
- This was caused by the server trying to access client-side keybinding code.
- The logic has been refactored to use a network packet, ensuring interactions work correctly regardless of the keybind setting.
- Resolved World Gen Config Weirdness**
- Previously, world-gen settings like spawn weights and biome lists were locked on the title screen because they were bundled with other synced server settings, making it impossible to configure them before creating a Singleplayer world.
- The configuration system has been restructured: clicking "Adorable Hamster Pets" in the mod menu now opens a new landing page with two distinct buttons: **"Main Settings"** (gameplay & client options) and **"World Gen Settings"**.
- The new "World Gen Settings" menu uses a special save mode (
SaveType.SEPARATE), allowing you to freely edit your local defaults for Singleplayer worlds while still respecting server-side overrides when joining a Multiplayer server.

- Particles spawned from bed interactions use a standard gravity-and-friction model for a simple settling effect.
- Particles spawned from an upside down Hamster Bed, the Hamster Bedding item or a dispenser use a "floaty" physics model, featuring a gentle pendulum-like sway based on sinusoidal motion.
- This floaty mode includes a deterministic, spatially-coherent wind gust simulation. It uses a grid-based hashing function to ensure particles in the same area react to the same pseudo-random wind events, creating synchronized, emergent behavior.
- New Intelligent Indoor/Outdoor Detection Algorithm for Particles**
- Implemented a custom algorithm to prevent the wind gusts from the particle system from having an effect on particles that are "indoors."
- The system analyzes three environmental factors in real-time: skylight levels, vertical roof clearance, and horizontal openness (i.e., proximity to open doorways or windows).
- It uses a high-performance caching system to minimize performance impact and employs hysteresis to prevent visual flickering when particles are near the threshold between an indoor and outdoor space.
- New Feature: Tamed Wander Mode**
- Tamed hamsters can now be set to "Wander Mode," allowing them to roam freely within a configurable radius of their linked bed instead of constantly following the player.
- Activation:** Link a Hamster Bed item to a hamster, then place it in the world.
- Control:** Right-click the placed bed to toggle Wander Mode on or off for the linked hamster. Sneak + right-click to cycle through three wander distances (Near, Medium, Far), which are configurable.
- Hamsters in Wander Mode will automatically seek out their bed to sleep based on the time of day (or the "Circadian Chaos" random timer) if enabled in the config.
- Added "The Great Escape" Guide Book Entry:**
- Details the crafting and use of the new Hamster Bed and Hamster Bedding items, featuring custom artwork.
- Explains how to link a bed to a hamster to enable "Tamed Wander Mode."
- Outlines all interactions for configuring wander distance, luring to bed, and unlinking.
- New Animations and Sounds for Sit/Stand/Sleep**
- Added new animations for sitting down, standing up, and waking from sleep.
- Added new
hamster_swishandhamster_thumpsound effects that play during these transitions, making interactions feel more realistic and fun. - New Dispenser Behavior for Hamster Bedding**
- Dispensers can now be loaded with Hamster Bedding. When activated, they will shoot out a decorative puff of the new floaty leaf particles, consuming one Hamster Bedding item.
- New Advancements for Wander Mode and Crafting**
- Added a new branch to the "The Hamster Life" advancement tab to guide players through the new features.
- New advancements include: "Artisanal Floor Mulch" (crafting bedding), "Luxury Leaf Pile" (crafting a bed), "Home is Where the Leaves Are" (linking a bed), "Sweet Dreams 'r Made of Leaves" (hamster sleeping in a bed), and a hidden challenge advancement for placing a bed upside-down.
- New Jade Integration for Hamster Bed**
- If the Jade mod is installed, looking at a Hamster Bed will now display a detailed tooltip.
- It shows which hamster the bed is linked to, whether Wander Mode is active, the current wander distance, and whether the hamster is allowed to sleep in the bed. Sneaking reveals detailed instructions on how to control the bed's functions.
- Added Compatibility for Croptopia, Immersive Engineering, Serene Seasons, and Thermal Expansion**
- A huge thank you to [@CasualAnimalEnjoyer](https://github.com/CasualAnimalEnjoyer) for creating 30 new resource files to ensure out-of-the-box compatibility.
- Croptopia:** Food recipes now accept AHP vegetables via tags. Seed crafting recipes have been separated to ensure crafting an AHP vegetable yields an AHP seed, preventing conflicts with Croptopia's own seed recipes.
- Serene Seasons:** Cucumber and Green Bean crops now have defined growing seasons and will bloom accordingly.
- Tech Mods:** Added support for growing Cucumber and Green Bean crops in the **Immersive Engineering** Garden Cloche and the **Thermal Expansion** Phytogenic Insolator.
- New Mod Icon**
- Huge thanks to [@The Retro Stitcher](https://theretrostitcher.com/) for re-designing the mod's icon!
### Changed
- Announcement icon position in Creative Inventory**
- The announcement bell icon that appears in the Creative Inventory screen has been moved from the bottom-right corner to the top-right corner of the screen.
- This relocation prevents the icon from being overlapped by popular inventory utility mods such as JEI, REI, and EMI.
- The maximum configurable X/Y offsets for the creative inventory widget have also been increased from 100 to 500 to allow for greater user customization.
- Improved the "Settle to Sleep" Animations**
- Tweaked the "Settle to Sleep" Animations to make them considerably cuter and more compatible with scenarios where the hamster might be "jumping into bed."
- Smarter Hamster Pathfinding (Bed Avoidance)**
- Hamsters now have a custom navigation system that makes them aware of Hamster Beds.
- By default, a hamster will now attempt to pathfind *around* any Hamster Bed that is not its own linked bed. After all, hamsters can be a bit territorial irl.
- To prevent hamsters from getting stuck in complex environments, they will only try a few alternate routes before giving up and taking a more direct path. This avoidance behavior can be disabled in the config.
### Fixed
- Personality ID assignment for command-spawned hamsters**
- Resolved an issue where hamsters created using the
/summoncommand were not being assigned a random "personality ID," causing them all to use the same animations and sitting poses. - This was caused by the
/summoncommand bypassing theinitialize()method where the ID was being set. - Orange hamster spawning in Stony Shore biomes**
- Fixed a bug where orange hamsters were incorrectly spawning in the
minecraft:stony_shorebiome instead of the intended light/dark gray variants. - The biome was being correctly excluded from the "white" variant spawn list but did not match any other specific criteria, causing it to fall back to the default orange variant. The spawn conditions for gray hamsters now explicitly include this biome.
- Startup crash (
StackOverflowError) related to the announcement system** - Fixed a critical
StackOverflowErrorcrash that would occur on game launch if the "Snooze (Session)" feature had been used in the previous session. - The crash was caused by a recursive loop in the
AnnouncementManager's initialization logic. The redundant check causing the loop has been removed. - "Snooze (Session)" functionality and state synchronization with Patchouli**
- The "Snooze (Session)" button now correctly snoozes only the specific announcement being viewed, rather than incorrectly disabling all notifications globally for the session.
- The underlying
disabled_until_launchsystem, which was the source of the startup crash, has been completely removed and replaced with a non-persistent, in-memory list for session-snoozed items. - Fixed a bug where announcements snoozed for the session would remain marked as "read" in the Patchouli guide book after restarting the game. The system now correctly syncs the "unread" status of all pending notifications with Patchouli's data when a world is loaded.
- Ghost Shoulder Hamsters on Player Death**
- Resolved a critical bug where shoulder-mounted hamsters would remain on the player after death, becoming permanently stuck. They will now correctly spawn at the player's death location in a 'knocked out' state, and a new config option allows players to keep them on their shoulder upon respawn if desired.
- Implemented a backward-compatibility fix to ensure any hamsters that were previously stuck on a player's shoulder can now be dismounted correctly.
- Stale triggerable animations playing when entity is rendered**
- Fixed a visual desynchronization where a one-shot animation (like the "Settle to Sleep" transition) triggered while a hamster was off-screen would play belatedly as soon as the hamster was rendered, causing it to be out of sync with the new sound effects.
- A server-side cancellation scheduler now ensures that any triggered animation automatically expires if it has not been played by a client within its expected duration.
- Hamster and wild bush spawning on Sculk, Clay, and Moss blocks**
- Black hamsters can now correctly spawn on Sculk blocks, decreasing their unintentional rareness in the Deep Dark biome.
- Wild Green Bean and Wild Cucumber bushes can now generate on Clay and Moss blocks, allowing them to spawn more frequently in biomes like Swamps, especially if you have a mod that modifies the block palette of the ground in those areas.
- Resolved "Unknown message ID" errors on dedicated servers (1.20.1)**
- Split the 1.20.1 network packet registration into distinct client-to-server and server-to-client methods. (This had already been done on 1.21.1)
- Ensured that the server correctly registers handlers for client packets (like render state updates), preventing disconnects or log errors when players interact with hamsters.
- Corrected Gray Hamster spawning in deserts.**
- Gray hamsters were incorrectly spawning in sandy biomes like deserts, where Cream hamsters are intended to appear.
- Added the
c:is_sandytag to the Gray variant's exclusion list to prevent this overlap. - Note:** If you're still seeing Gray hamsters in deserts, navigate to
Spawn Settings > Variant Spawning > Gray Variants > Excluded Tagsin the config menu, right-click the setting, and select "Restore Defaults." - Fixed Uninteractable Hamsters with Force-Mount Keybind**
- Resolved a critical bug where enabling the "Force Shoulder Mount" keybind in the config would prevent all interactions with tamed hamsters.
- This was caused by the server trying to access client-side keybinding code.
- The logic has been refactored to use a network packet, ensuring interactions work correctly regardless of the keybind setting.
- Resolved World Gen Config Weirdness**
- Previously, world-gen settings like spawn weights and biome lists were locked on the title screen because they were bundled with other synced server settings, making it impossible to configure them before creating a Singleplayer world.
- The configuration system has been restructured: clicking "Adorable Hamster Pets" in the mod menu now opens a new landing page with two distinct buttons: **"Main Settings"** (gameplay & client options) and **"World Gen Settings"**.
- The new "World Gen Settings" menu uses a special save mode (
SaveType.SEPARATE), allowing you to freely edit your local defaults for Singleplayer worlds while still respecting server-side overrides when joining a Multiplayer server.
