Aperture Litewer's Portal Gun
by Litewer
Aperture Litewer's Portal Gun adds a craftable portal device to Fabric, letting players place two linked portals on walls, floors and ceilings for puzzle play.
What it does
Aperture Litewer's Portal Gun adds a portal gun that places two linked portals, one entry and one exit, on most solid blocks. Momentum carries through a portal, so speed is kept as a player moves from one side to the other, which suits puzzle maps and adventure play in survival or multiplayer. Special lunar surfaces allow portal placement that ordinary blocks do not, and some blocks resist portals altogether.
The mod requires Geckolib and Immersive Portals, both of which must be installed alongside it on Fabric. It is published for 1.20.1 and 1.21.1 under the Creative Commons Attribution 4.0 license, and it is not open source. Every player and the server need a copy of the mod.
Key features
Linked dual portals
Two portals are linked so that anything entering one exits from the other.
Momentum physics
Speed is preserved through the portal, which makes the device useful for movement puzzles.
Lunar portal surfaces
Special moon surfaces accept portal placement, adding a separate set of puzzle locations.
Craftable portal gun
The portal gun can be crafted in survival, so it fits into normal progression rather than needing commands.
Portal-resistant blocks
Some blocks reject portals, which sets limits on where a portal can be placed.
