      GUI Spawner Plugin for Minecraft Servers

modrinth ghpages

Why SmartSpawner?

Say goodbye to entity lag forever. SmartSpawner calculates mob drops and XP virtually - no actual mobs spawn, no AI processing, zero pathfinding eating your tick. This plugin is inspired by the iconic spawner mechanic from DonutSMP now available on your own server.

Perfect for: Survival servers • Skyblock • Prison • Factions • Any server where spawners matter

Highlighted Features

Feature Description
Spawner Holograms Floating text displays above every spawner showing mob type, stack count, and real-time status - always visible at a glance.
Hopper Integration Hoppers automatically drain items from spawner virtual storage into adjacent containers, enabling fully automated farming pipelines.
Mineable Spawners Fully configurable breaking mechanics - require Silk Touch to drop spawners, set custom drop chances, and tailor the behavior to perfectly fit your server's rules.

[1.8.3] SmartSpawner 1.8.3 by Nightter on Oct 12, 2026
Download
### Fixed
  • Opening a spawner's storage while another player was using it could leave the menu stuck open with its ghost items takeable. In creative mode those items were kept. The player now stays on the spawner menu with a "storage in use" message.

### Added
  • Custom spawners: any number of extra spawners for the same mob or item, each with its own loot, set up under custom_spawners. They stack only with each other and are given by their own name.
  • display_name gives a spawner its own name on the item, in menus and on the hologram, so players can tell custom spawners apart.
  • Each spawner can have its own menu head and drop chance. A custom spawner takes anything it leaves out, except loot, from the normal spawner of its mob or item.
  • A custom spawner can be renamed without losing the ones already placed by listing the old name under aliases.
  • The console warns about spawner names that clash, and about placed spawners whose spawner was removed from the settings files.

### Changed
  • /ss give is shorter: /ss give <player> <spawner> [amount], for example /ss give Steve zombie 5. Vanilla spawners use /ss give <player> vanilla <mob> [amount].
  • spawner_mobs.yml and spawner_items.yml use a simpler layout. Each mob or item is listed under its own name, and custom spawners have their own section. See the details below.

### Notes
  • Both settings files are converted on the first start, and the old files are kept with a .1.8-backup ending. Placed spawners and spawner items keep working and stack with new ones. No action is required.
  • The old give form (smart_spawner, item_spawner, vanilla_spawner) still works from the console and command blocks, so shop, crate and vote setups need no changes.

<details>
<summary>Configuration file details</summary>

  • Entries are keyed by the mob or item itself: zombie_spawner: with entity: ZOMBIE becomes zombie:, and diamond_spawner: with item: DIAMOND becomes diamond:.
  • Entries that were not named after their mob or item move under custom_spawners, keeping their entity or item line.
  • New optional keys on every entry: display_name and aliases.
  • Spawner names now match the entry keys, so zombie_spawner is zombie in commands. The old names are still accepted.

</details>
[1.8.2] SmartSpawner 1.8.2 by Nightter on Oct 12, 2026
Download
  • This release fixes a critical item duplication exploit. Update as soon as possible.**

### Fixed
  • Item duplication in the spawner storage menu involving multiple players with Autism Client.
  • Clicking items quickly in the storage menu no longer floods chat with "clicking too fast" and "inventory full" messages.

### Added
  • Spanish (es_ES) language.
  • Sulfur Cube spawner support for servers on Minecraft 26.2. Its spawner drops no items and gives 2 experience.

### Changed
  • Happy Ghast, Copper Golem and Sulfur Cube now show a translated name in every language.
[1.8.1] SmartSpawner 1.8.1 by Nightter on Oct 12, 2026
Download
### Fixed
  • Breaking a spawner and placing a new one at the same spot no longer triggers a database save error. Spawner data now saves reliably in this case.

### Changed
  • Spawners that store tools, weapons or armor with different durability now save using less database space.
  • Sorting items in the storage menu is faster.
  • When a claim or region plugin blocks an action on a spawner, only that plugin's own message shows. SmartSpawner no longer adds a second protection message on top.
  • GriefPrevention now uses separate trust levels for each action. Breaking or placing a spawner needs build trust, while opening a spawner's storage menu only needs container trust.

### Notes
  • Spawner storage now uses a more compact save format. Existing data is read and upgraded automatically, and no action is required.
[1.8.0] SmartSpawner 1.8.0 by Nightter on Oct 12, 2026
Download
  • This release contains several breaking changes.** Back up the plugins/SmartSpawner/ folder before updating. The give commands changed shape, spawner settings files were renamed and are not carried over, YAML storage and the Bedrock form menus were removed, and several config keys moved. Read the Removed and Notes sections below before updating a live server.

### Added
  • Custom spawners can now be created. The same mob or item can be set up under several names, each with its own drop table, so one entity can power many different spawners.
  • Custom items can now be spawner drops, including potions, enchanted gear, named items and items from other plugins. They keep all of their data and show their real in-game name in every menu.
  • /ss editloot <name> opens an in-game loot editor for mob and item spawners. Drop an item into the menu to add it as a drop, captured exactly with all of its data, then set its amount, chance and durability. Existing drops can be edited or removed. Durability is shown only for tools and weapons.
  • Sneak stacking and sneak placing can each be turned off with sneak_stack and sneak_place in config.yml. Both stay on by default.

### Fixed
  • Item Spawner holograms now show the spawned item's name instead of a generic entity label.
  • Sneak-placing a whole stack of spawners now fires the stacking event in the API, so it can be cancelled and limited like normal stacking.
  • A spawner type change cancelled through the API no longer takes the player's spawn egg.

### Changed
  • Give commands now put the player first, as /ss give <player> smart_spawner|item_spawner|vanilla_spawner, and only suggest names of online players. The spawner type was renamed to smart_spawner. Smart and item spawners are still selected by their configured name.
  • SQLite is now the default storage and is faster than the old YAML files on servers of any size. MySQL and MariaDB work as before, including cross-server spawner listing.
  • How often spawner data is saved can now be set with database.autosave-interval, which defaults to 3 minutes.
  • Large spawner stacks and full storages use far less CPU and memory. Loot generation, storage menus, hoppers and selling were all reworked to stay fast with large amounts of items.
  • Menus respond faster to clicks.
  • Settings that only take effect after a full restart are now marked RESTART in config.yml.
  • Selling and action logging settings moved into clearer files, and the database section was simplified. Existing settings move across automatically on the first start. See the details below.
  • The two spawner settings files were renamed and loot entries use a new format. See the details below.

### Removed
  • YAML storage was removed. Servers still set to YAML are switched to SQLITE automatically.
  • Bedrock form menus were removed. Bedrock players now use the same chest menus as Java players, and the bedrock_support section of config.yml is gone.
  • The stacker menu was removed, along with the admin stack editor in /ss list. Spawners still stack by placing one spawner on another of the same type, controlled by the smartspawner.stack permission.

### Notes
  • Spawner settings are not carried over.** The two renamed files are created fresh in the new format, and the old files are left untouched beside them so customised drop tables can be copied across by hand. The console reports this on the first start.
  • Spawner data is migrated automatically. spawners_data.yml is renamed to spawners_data.yml.migrated so nothing is imported twice.
  • Back up the plugins/SmartSpawner/ folder before updating. The plugin also copies the old data inside the database before converting it.
  • If the database cannot be opened, the plugin stops instead of running without saving. The console reports the reason.
  • Every renamed config key is migrated on the first start, so no config file needs editing by hand after updating.

<details>
<summary>Configuration file details</summary>

  • spawners_settings.yml is now spawner_mobs.yml, and item_spawners_settings.yml is now spawner_items.yml.
  • Each loot entry names its item on an item line. It accepts a material, the item text /give completes in game, or a code copied from the game.
  • The name above each entry is now only a label, so one mob can drop several versions of the same item, such as two different tipped arrows.
  • The old format, where the entry name doubled as the material name, is no longer read. The material line in item spawner entries was removed with it.
  • The potion_type line was removed. Name the potion inside item instead.
  • The spawner block head moved to mob_head, with item for the material and hash_texture for the texture code. It replaces head_texture with material and custom_texture.
  • The default_material line was removed. The fallback head is now built in.
  • A loot entry the server cannot read is skipped, and the console names the mob and the entry.
  • The guide in the comments at the top of both files was replaced with a link to the documentation site.
  • The storage button in the main menu now accepts the {total_sell_price} placeholder, showing the sell value of everything stored, as the info button already does.
  • discord_logging.yml is now activity_log.yml, and the logging section of config.yml became its file section. Both moves happen on the first start and keep the configured values.
  • Inside that file the Discord settings sit under discord, and the per-event message templates sit under embeds, one block per event with the embed line removed.
  • The sell_integration section of config.yml became the top level of sell_integration.yml, so its keys lost the sell_integration. prefix. item_prices.yml became the custom_prices.prices section of that file and is deleted once its prices have been copied across.
  • A price removed from custom_prices.prices stays removed and is not added back on the next start.
  • The database section was flattened and its keys now use hyphens. mode is type, table_prefix is table-prefix, server_name is server-name, sync_across_servers is sync-across-servers, migrate_from_local is migrate-from-local, sqlite.file is sqlite-file, and the four sql connection keys moved up a level.
  • sql.pool.maximum-size is now pool-size and covers both storage modes. The other pool tuning keys and sqlite.pool_size were removed and are set internally.
  • The new database.autosave-interval accepts the usual time format, with a minimum of 30 seconds. It is the only setting in the section that /ss reload applies.
  • Database columns were shortened: world_name is world, item_spawner_material is itemspawner_type, spawner_exp is exp, spawner_active is active, spawner_range is activation_range, spawner_stop is stop, spawn_delay is delay, and max_spawner_loot_slots is max_loot_slots. entity_type keeps its name.
  • Columns are now grouped by subject in the table, so location, spawner type, stacking, spawning, stored loot, stored experience and player settings each sit together.
  • The server_name column was removed. A table now holds one server's spawners and says which in its name, so the column held the same value on every row.
  • With sync-across-servers on, this server's table is <prefix><server-name>_data instead of <prefix>data. Switching the setting renames the table, and an existing table at the target name is never overwritten.

</details>
### Fixed
  • GUI layout button changes now persist correctly after a restart or /ss reload, including moved and deleted buttons.
  • Clicking the sell button in an empty storage no longer returns to the main menu. Stored experience is collected when available; otherwise, the storage empty message is shown.
  • Updated the bundled sell_confirm_gui.yml layouts to the current click-action format, preventing unnecessary value migrations on fresh installations.
  • DonutSMP storage titles now use the correct singular or plural form and remain consistent after pagination or refreshes.
  • Dynamic storage lore placeholders, including {total_sell_price} and {current_exp}, are now replaced correctly.

### Notes
  • Previously restored buttons must be moved or deleted once after updating.
  • Customized button sections no longer receive new bundled buttons automatically. Other layout settings continue to update normally.
  • Delete a layout file and restart the server to restore its default content
### Fixed
  • Removed mob drops in spawners_settings.yml are no longer restored after a restart or /ss reload.
  • Removed message components, such as chat messages, action bars, sounds, titles, and subtitles, are no longer restored automatically.

### Removed
  • Removed generation of the outdated language/CHANGELOG.txt file.

### Notes
  • Previously restored drops or message components must be removed once after updating.
  • Customized drop lists and messages are preserved, while entirely new mobs and messages are still added with their default content.
  • Existing language/CHANGELOG.txt files are left unchanged and can be removed safely.
  • GUI and formatting language files retain their previous update behavior.

[1.7.1] SmartSpawner 1.7.1 by Nightter on Oct 12, 2026
Download
### Added
  • Added FactionsUUID support. Spawners now respect faction access rules when opening menus or stacking.
  • Added BlockLocker support. Spawners protected by [Private] signs now restrict menu access, stacking, and breaking to authorized players.

### Changed
  • Config and language files now update automatically while preserving existing values and comments.
  • Update backups are no longer created because configuration changes are applied in place.
  • Obsolete config_version entries are now removed automatically.
### Fixed
  • Fixed a crash that could happen when breaking a vanilla spawner that had no mob type set. This no longer throws an error and the spawner now breaks normally.
  • Fixed an error that could appear in the console when a Bedrock player (via Floodgate/Geyser) opened a spawner menu or storage on Folia based servers. Menus now open reliably for these players.
  • Removed the "Server Version Not Supported" warning message. It was showing up incorrectly on newer supported server versions and is no longer needed.
  • Update notifications will no longer mention SmartSpawner2 versions (2.0.0 and above). SmartSpawner2 is a separate product, so 1.x servers will only be notified about relevant 1.x updates.

### Added
  • Re-added RedProtect support. Spawners inside RedProtect regions now respect region permissions again when opening menus or stacking spawners.

### Notes
  • This is a maintenance release focused on stability. No configuration changes are required to update.
### Bug Fixes
  • Fixed sell_and_xp_break preventing players from breaking a spawner when its
stored items had no sell value (or the sale was cancelled). Breaking a spawner
now always succeeds - auto-sell and XP collection remain a best-effort bonus.
  • Fixed the configured open_sound not playing when skip_main_gui opens the
storage GUI directly.

### Compatibility
  • Updated EconomyShopGUI integration to API 1.10.1.
  • Updated Towny integrations to their latest supported versions.

[1.6.9] SmartSpawner 1.6.9 by Nightter on Oct 12, 2026
Download
This release expands GUI customization and improves the reliability of spawner management across different server environments.

### What's New

  • Added support for custom player-head textures on buttons in the main and storage GUIs.
  • Custom textures can be applied to navigation, storage, experience, sorting, selling, and other configurable GUI buttons.
  • Added a dedicated GUI layout guide with examples for configuring custom textures and conditional button styles.

### Improvements

  • Improved spawner removal from management menus, including spawners located in unloaded chunks.
  • Related menus now close automatically when a spawner is removed, preventing players from interacting with outdated inventories.
  • Improved the reliability of stacking and admin management actions while a spawner is being modified or removed.
  • Improved nearby-spawner highlight cleanup and session handling.
  • Refreshed the documentation website with clearer navigation, updated branding, and improved readability.

### Compatibility

  • Updated compatibility with newer SimpleClaimSystem releases.
  • Updated compatibility with plugins using the latest NightCore release.

### Developer API

  • Added removeSpawner(Location location) to remove a SmartSpawner at a specific location.
  • Both methods return a CompletableFuture<Boolean> and complete after the spawner block and stored data have been removed, including when its chunk must be loaded first.

### Fixes

  • Fixed the en_US_DonutSMP_v2 language pack not being included under the expected resource path, which caused missing-resource warnings and prevented its language files from loading.
  • Prevented overlapping spawner actions from causing inconsistent spawner data.
  • Prevented explosions and manual breaking from interfering with spawners already being removed.
  • Improved menu behavior when a managed spawner is no longer available.

[1.6.8] SmartSpawner 1.6.8 by Nightter on Oct 12, 2026
Download

[1.6.7] SmartSpawner 1.6.7 by Nightter on Oct 12, 2026
Download
## New Features

### New /ss set Command

Added a new admin command to quickly update SmartSpawner properties in-game.

Admins can now set:

  • Stack size
  • Spawn range
  • Spawn delay

The command can be used on the spawner the player is looking at, or with exact world coordinates for console/admin use.

### New Performance Settings

Added new performance options for loot generation. These settings help large stacked spawners run more smoothly by using a faster calculation method when extremely large amounts of loot are generated.

This is enabled by default and is recommended for most servers.

## Improvements

### Better Loot Generation Performance

Large spawner stacks now handle loot generation more efficiently, reducing heavy processing during big spawn cycles while keeping results realistic over time.

### Improved Item Giving Behavior

The /ss give command now handles full inventories more reliably. If the player does not have enough space, extra items will be dropped safely at their location instead of being lost or handled incorrectly.

### Clearer Configuration

The selling configuration has been renamed and reorganized to make it easier to understand.

The old custom_economy section has been replaced with sell_integration, which better describes what the feature is used for.

## Compatibility Changes

### ExcellentEconomy Support

SmartSpawner now supports ExcellentEconomy for storage selling.

CoinsEngine support has been replaced by ExcellentEconomy.

### Shop Integration Updates

ExcellentShop integration has been removed.

Supported shop integrations now include:

  • EconomyShopGUI
  • EconomyShopGUI Premium
  • ShopGUI+
  • zShop

## Important Notes

  • SmartSpawner now requires Java 25 or newer.
  • Existing sell-related configuration values are migrated where possible.
  • A new permission has been added: smartspawner.command.set.
[1.6.6] SmartSpawner 1.6.6 by Nightter on Oct 12, 2026
Download
### New Features

  • Auto-Sell & XP Claim on Spawner Break**
Added support for automatically selling items and claiming XP when a spawner is broken. Configuration loading has also been enhanced for better reliability and flexibility.

  • Version 26.x Support**
Updated compatibility to include the latest minecraft version, ensuring SmartSpawner works seamlessly on the most recent Minecraft releases.

### Improvements

  • Experience Fields Migrated to long Type**
All experience-related fields have been migrated from int to long, significantly increasing capacity and precision for high-volume or long-running servers.

### Bug Fixes

  • Fixed: Spawner Disappearing When Surrounded by Blocks**
Resolved a critical bug where a spawner would vanish if it was completely enclosed by blocks. The fix ensures a valid drop location is always located nearby, even in tight spaces.

  • Fixed: Money Stacking Up with GUI Open on Full Storage**
Resolved an issue where currency would continue accumulating even after the spawner storage was full, as long as the GUI remained open. Money will no longer stack up when storage capacity has been reached.

  • Fixed: Drop All Button Dropping Items in Inconsistent Directions**
The "Drop All" button in the Spawner GUI now drops items in a consistent, predictable direction instead of randomly scattering them.

  • Fixed: Placeholder Errors in Some Embeds Not Displaying Information**
Certain embed messages were failing to resolve placeholders correctly, resulting in missing or blank information. This has been corrected alongside the event logging improvements.

### Removed

  • RedProtect Integration Removed**
All RedProtect hooks and related references have been removed from the codebase. If you were relying on RedProtect integration, please consider an alternative region protection solution.

> Hotfix & compatibility update following v1.6.3

### Bug Fixes

  • Resolved plugin crash introduced in v1.6.3 when running on Minecraft 1.21.4 and below.
  • Fixed hook integration with the **Residence** protection plugin.

types, regardless of the protect_from_explosions config value.

### New Integrations

  • Added support for **HuskClaims** land-claim plugin.
  • Added support for **SimpleClaimSystem 2**.
  • (Thanks to Xyness, the plugin author, for the contribution.)*

### Performance

  • Optimized the selling process for improved throughput and transaction security.

## New Features

### /ss near [radius] Command
Added a new command that scans for nearby spawners within a specified radius and highlights them through walls. All discovered spawners are displayed in a dedicated GUI for easy management.

### Collect XP Button in Storage GUI
A new **Collect XP** button has been added directly to the spawner storage GUI, allowing players to collect accumulated experience without opening a separate menu.

### Centralized Discord Logging Configuration
Discord logging is now fully configurable through a dedicated discord_logging.yml file. Each embed can be individually customized, giving server administrators complete control over the appearance and content of Discord notifications.

### Language Changelog Files
Added language changelog files to make it easier for users to maintain and update their custom language translations across versions.

### New API Events
  • SpawnerTakeAllEvent** - Fired when a player clicks the "Take All" button in the spawner storage GUI.
  • SpawnerDropAllEvent** - Fired when a player clicks the "Drop All" button in the spawner storage GUI.


## Bug Fixes

  • SimpleClaimSystem (Paid Version)** - Fixed a crash that occurred when using the paid version of SimpleClaimSystem. SmartSpawner now only hooks into the free version of SimpleClaimSystem. ([#185](https://github.com/NighterDevelopment/SmartSpawner/pull/185))
  • Memory Leak in Sell Operation** - Fixed a memory leak caused by itemToRemove not being properly cleared during sell operations in the spawner inventory.
  • ExcellentShop Sell Prices** - Fixed sell prices not being loaded correctly when ExcellentShop is used as the price provider.
  • Spawner Loss on Stack Limit Reduction** - Fixed a bug where reducing the maximum stack limit would delete spawners that exceeded the new limit. Spawners are now properly preserved when the limit changes.
  • Spawner Item Floating Near Bedrock** - Fixed an issue where broken spawner items would float upward into a cave pocket above the player when mining near bedrock with no block directly behind the spawner.


## Improvements

  • Discord Logging Performance** - Optimized the Discord logging system to reduce overhead and improve overall server performance when logging is enabled.

# SmartSpawner - Version 1.5.6.2
## Critical Dupe Patched
  • Fixed item duplication exploit caused by race condition in VirtualInventory synchronization with storage GUI

## Technical Details
The exploit involved using two game instances with swarm mode (custom mod) to create a race condition between spawner inventories. This has been completely patched by:
  • Synchronizing inventory operations across all connected clients
  • Adding transaction verification before committing item changes
  • Implementing proper locking mechanisms for concurrent access

  • All users running v1.5.4.3 or lower should update immediately.**

# SmartSpawner - Version 1.5.6

## 🎯 What's New

### ✨ New Feature: Item Spawners

#### What are Item Spawners?
  • New spawner type** with the appearance of a specific item in the spawner block
  • All the same features as regular spawner spawners (storage, stack, etc.)

### 📝 Configuration

#### New Item Spawner Settings File
  • Added item_spawners_settings.yml for full control over item spawner behavior
  • Customize spawn loots, experience, and other settings
  • New command: /ss give item_spawner <player> <item_type> [amount]

### 🔧 Bug Fixes

#### Fixed Storage GUI Page Display Issues
  • Problem**: When you removed items from your spawner storage, the page counter at the top would sometimes show weird placeholders like [{current_page}/{total_pages}] instead of the actual page numbers like [1/1]
  • What fixed**:
  • Page numbers now always display correctly when you take items out of storage
  • When your spawner generates loot while you have the storage open, the page counter updates properly
  • The GUI title now always shows the right page you're on and total pages available

### 🛡️ Security & Performance Improvements

#### Added Anti-Spam Protection for Storage GUI
  • What this means**: We've added a short cooldown (half a second) between opening and closing your spawner storage
  • Why this helps**: Prevents issues with cheater try to spam-click or use macros in GUIs
  • Your experience**: You won't even notice this - it only blocks actions that happen too fast to be intentional

#### Optimized Storage Title Updates
  • What changed**: The plugin now only updates the page counter when it actually needs to (like when moving between pages)
  • Benefit**: Better performance, especially if you have many items in storage

### 🔌 Developer Features

#### New API Methods for Custom Spawners
Plugin developers can now create:
  • Vanilla Spawners**: Natural spawners that spawn mob
  • Item Spawners**: Special spawners with the appearance of a specific item in the spawner block


## 📋 Summary

This is a major feature update! We've introduced **Item Spawners** - a completely new way to use spawners for automatic item generation. Plus, we fixed annoying storage GUI display bugs, added protection against spam-clicking, and improved overall performance.

  • Upgrade highly recommended**: New features + important bug fixes and stability improvements.
