PortalGunMod
by ButterBoyRS
With Portal Gun, a player fires blue and orange portals onto valid walls, floors and ceilings, and anything that moves through one keeps its speed and direction.
What it does
The mod brings Portal-style traversal to Minecraft: a gun places a linked pair of blue and orange portals on solid surfaces, with automatic orientation alignment. While a player, mob, arrow, snowball or other supported projectile passes through a portal, it retains its speed, so momentum carries across the transit. Each player owns a personal portal pair, which keeps multiplayer play clean because portals do not interfere with other players.
Portal Gun also covers grabbing and throwing. Pressing G grabs nearby mobs or supported solid blocks, including Monster Spawners with their block entity data intact, and left or right click throws them while grab mode is active. A portal opened under the moon at night works as a black hole, drawing nearby players, mobs and blocks toward its center.
The mod is a Fabric build for 1.21.1 – 1.21.11, with 1.2.0 as the latest file for 1.21.11. Every player and the server need a copy of the mod. It is released under the MIT License and is not open source. Portal Gun counts among 840 Transportation mods with Fabric files for 1.21.11.
Key features
Blue and orange portals
Portals attach to solid walls, floors and ceilings and align to the surface they sit on.
Momentum-based teleportation
Entities and projectiles keep their velocity and direction while passing through a portal.
Grab and throw
A grab mode lifts nearby mobs and blocks, which can then be launched with a click.
Moon portals
Portals opened under the moon during the night act as a black hole that draws nearby entities and blocks inward.
Portal-style first-person animations
Custom recoil, muzzle effects and claw movement replace the standard hand motion while holding the gun.
