Portal Gun brings Portal-style traversal and physics to Fabric 1.21.11, with smooth portal placement, momentum-preserving teleportation, grabbing, throwing, portal viewing, and a polished first-person Portal Gun experience.
Fire a blue and orange portal onto valid walls, floors, or ceilings, then move through them while keeping your speed and direction intact. Each player gets their own portal pair, making the mod multiplayer-friendly without portals interfering with each other.
The goal is simple: make portal movement feel fast, clean, and satisfying while staying as close as possible to the style and behavior you’d expect from Portal.
✦ Features Blue and Orange Portals Place portals on solid surfaces including walls, floors, and ceilings with automatic orientation and alignment.
Momentum-Based Teleportation Players, mobs, arrows, snowballs, and other supported projectiles preserve their velocity when traveling through portals.
Portal View Rendering Look through one portal and see a pixelated view from the other side, including support for portals across dimensions.
Personal Portal Pairs Every player has their own blue and orange portals, keeping multiplayer gameplay clean and independent.
Portal Stability Portals automatically fizzle if the blocks supporting them are removed.
Portal-Style First-Person Animations The Portal Gun features custom recoil, muzzle effects, claw movement, and clearing animations instead of standard Minecraft hand motion.
Custom HUD Reticle Portal-style reticle indicators show portal availability and active portal status while holding the gun.
Grab Tool Press G to grab nearby mobs and hold them in front of you.
Block Grabbing Pick up and move supported solid blocks, including Monster Spawners, while preserving their block entity data.
Throwing Launch grabbed mobs or blocks using left-click or right-click while grab mode is active.
Moon Portals At night, portals placed on the moon can create a black-hole effect that pulls nearby players, mobs, entities, and supported blocks toward it.
Portal Gun Pedestal Display your Portal Gun on a custom Aperture-inspired pedestal designed to fit the mod’s clean sci-fi look.
Custom Sounds Dedicated sounds for firing, teleporting, clearing portals, grabbing, releasing, and other Portal Gun actions.
✦ Controls V — Clear your portals G — Grab or release mobs and supported blocks Left/Right Click while grabbing — Throw the held object
✦ Design Portal Gun is built around smooth movement, clean visuals, responsive physics, and a strong Portal-inspired style without adding bulky portal frames or unnecessary setup.
The mod is still actively being developed, so new mechanics, visual improvements, and refinements will continue to be added over time.

All Versions
+ Add Version
- Aligned mod metadata with the current Minecraft 1.21.11 build target.
- Hardened server packet handling for portal shooting and clearing.
- Changed normal portal clearing to clear only the requesting player's portals.
- Added an operator-only
/portalgun clear allcommand for full cleanup. - Improved portal lifecycle sync when portals are removed or fizzle.
- Reworked Portal Gun firing visuals to bypass vanilla first-person hand motion and add a Portal-style recoil, claw flare, and muzzle pulse.
- Added a first-person Portal Gun shake when clearing portals from the keybind.
- Added grabbed-mob visual feedback that holds the Portal Gun claws open and blocks portal shooting while grabbing.
- Added Portal Gun grab hold-loop and release/drop sound effects.
- Fixed grabbed mobs sometimes keeping no-gravity and floating after release.
- Prevented grabbed mobs from being pushed into solid blocks by clamping the held position to open space.
- Added Portal Gun block grabbing for solid opaque blocks, excluding transparent, portal, portal-frame, block-entity, and unbreakable blocks.
- Added Monster Spawner block grabbing while preserving the moved spawner's block entity data.
- Added a Portal Gun "too heavy" sound when a targeted entity or block cannot be grabbed.
- Added throwing grabbed mobs and blocks with left-click or right-click while grab mode is active.
- Added night-only moon portals that turn the paired placed portal into a front-facing black-hole sink, pulling nearby mobs, players, entities, and eligible blocks harder at close range before destroying them.
- Fixed black-hole suction not reliably pulling players by explicitly applying and syncing player velocity.
- Added a linked-portal pixel view that samples and draws the other portal's visible side when both portals are placed.
- Fixed the linked-portal pixel view being hidden by the normal portal fill texture and added client-side fallback portal pairing.
- Changed the linked-portal pixel view to use camera-perspective rays through the paired portal while keeping the custom oval portal rings.
- Restored the original portal oval ring textures as the frame while keeping the generated linked-view interior texture-free.
- Made portal rendering less likely to disappear from angled camera directions by expanding client-side render culling.
- Tightened the linked-view interior mask to the remaining portal oval PNG opening and pushed the oval frame in front of the view.
- Fixed wall portal visuals disappearing on north/south placements by drawing wall-facing portal planes directly and double-siding the oval texture.
- Restored the linked-view interior to the normal translucent entity render layer so it draws reliably underneath the oval frame.
- Added a tinted portal interior fallback when the paired portal is not visible to the client, making pairing/render-layer issues easier to identify in game.
- Fixed east/west wall portal interiors not rendering by emitting non-degenerate X-plane quads for th
