Illusory Walls
by LCLPYT
Illusory Walls, a Fabric mod, lets a player turn chosen blocks into walls that can be seen through and passed through, with the block's look kept in place.
What it does
A player holds Shift and right-clicks the air while looking at a block to convert it into an illusory block, and the default settings can be changed to create new illusory walls. The mod is meant for map makers who want passages that look solid but can be walked through, and for players who enjoy hidden routes and secret rooms in adventure maps.
Illusory Walls is a Fabric mod, so it needs Fabric API installed alongside it in the mods folder of the game directory. It is open source under the MIT License and its source code and issue tracker are public. The mod runs on client and server, so a multiplayer server needs the mod installed too, along with Fabric API on the server and on each player's client.
