About this Mod
ShadertoyMC
CURRENTLY THIS IS A SINGLEPLAYER ONLY MOD
This minecraft mod allows writing scripts in Arucas with the goal of placing
blocks based on math.
The working logic is similar to how shadertoy works: an expression is calculated for each
block with
block coordinates as inputs and as a result of this expression a block is placed at the coordinates.
FabricAPI required
Easy start
Step 1
Create a new script with /shadertoy new <name>
This file will contain a working script and can be run immediately, but the area on operation is defined within the file
and might not match your desired are.
Step 2
Set the area with one of the
following: /area pos1 <pos> + /area pos2 <pos>, /area origin <origin> size <sizeX> <sizeY> <sizeZ>, /area <pos1> <pos2>.
Step 3
The file can be located in .minecraft/config/shadertoy. Recommended text editor: VSCode with Arucas extension
recommended.
Files can also be opened with /shadertoy open <name>.
Step 4
Run the script with /shadertoy run <name>.
