This mod is for the Fabric mod loader and Minecraft 1.17/1.18.
Recipe Reshaper allows you to replace groups of recipes with new ones based on the originals.
This is done using recipe reshaper datapacks, the mod has several already builtin:
Replaces traditional slab and stair recipes with ones that fit in the 2x2 inventory crafting grid and let you freely craft stairs, slabs and blocks into one another.
Adds 2x2 recipes to craft logs directly into slabs and stairs with 4 times the output of plank recipes.
Changes recipes for glass panes and iron bars to be 2x2 instead of 3x2 and output 10 instead of 1.
Changes sign recipes to be a slab on a stick and output 1.
Makes button recipes output 4 buttons
Changes pressure plate, chiseled block, and trapdoor recipes so they don't conflict with newly reshaped recipes.
There's also fixed_inconsistencies which doesn't have any reshapers but changes some edge case vanilla recipes that break patterns (currently only changes the light weighted pressure plate recipe).
The builtin recipe reshapers can be enabled and disabled using the standard
/datapack enable|dsiable commands, and you can add your own by putting them in your world's datapacks folder.
Recipe reshapers work by defining
result patterns, similar to the patterns used in vanilla shaped recipe JSON. Documentation on the datapack format is available on the wiki, and the builtin datapacks serve as good examples.
This is a server-side mod. It works in singleplayer, and clients connecting to servers with it don't need the mod.
This mod is only for Fabric and I won't be porting it to Forge. The license is MIT, however, so anyone else is free to port it.
I'd appreciate links back to this page if you port or otherwise modify this project, but links aren't required.
