Swap Mod
by Latibro
Swap Mod adds a Swapper block that exchanges two blocks when it receives a redstone pulse.
What it does
The Swapper block holds one target inside its internal storage and swaps it with the block in front of it or behind it when powered. Remote targets and the choice of direction let a single block trade places in several ways, which allows small animations such as stone turning into dirt and back, doorways that open by swapping with air, and piston-like part movement in redstone circuits. Swap Mod needs Fabric API and is published for Fabric and NeoForge, with files for 1.21 only. Every player and the server need a copy of the mod. The code is released under the GNU General Public License v3.0 or later and is open source.
Key features
Block swapping
A redstone pulse makes the Swapper exchange the stored block with a neighboring block.
Internal storage
One target is kept inside the Swapper, so it knows what to place when triggered.
Directional swapping
The Swapper can act on the block in front of it or the block behind it, like a piston.

Adds a block called "Swapper" that will swap two blocks when given at redstone pulse. This makes it possible to do things like small animations, where you have a stone block change to a dirt block and back again. Or you could create a doorway by swapping between a block and no block (air). You could also make it…
