RPack

Recipes I am missing in vanilla Minecraft, packed as a Fabric mod. Drop the jar into your mods folder and the recipes are active in every world, with no need to copy a datapack into each save.

Requires Fabric API. Builds for Minecraft 26.2 and 26.3.

Recipes

Crafting table

• 24 slabs from 3 logs, 16 stairs from 6 logs (every wood type, incl. nether stems; poplar on 26.3)
• 16 sticks from 2 logs, 4 chests from 8 logs (any log)
• 4 quartz from 1 quartz block, 4 clay balls from 1 clay block
• 4 string from 1 wool, 4 leather from 1 saddle
• Chainmail helmet, chestplate, leggings and boots from iron chains
• Spawner (iron bars), lodestone (stone + quartz)
• Grass block, mycelium, podzol, crimson and warped nylium
• Dispenser from dropper + bow, coal block from 9 charcoal
• 4 cobwebs from 4 string + slimeball, slime spawn egg from warped roots + egg
• Pointed dripstone from 5 dripstone blocks
• 7 crying obsidian from 7 obsidian + ghast tear + lava bucket

Smithing table (no template needed)

• 4 black dye from 2 charcoal
• Iron chain from 2 iron nuggets
• Chipped anvil + nugget → anvil; damaged anvil + nugget → chipped anvil; damaged anvil + ingot → anvil

Furnace and blast furnace

• Iron and gold tools, weapons and armor give back the ingots they cost: sword 2, pickaxe 3, axe 3, hoe 2, shovel 1, spear 1, helmet 5, chestplate 8, leggings 7, boots 4
• Chainmail armor gives back one iron ingot per chain (5/8/7/4)
• Bucket back to 3 iron ingots
• Horse armor back to 8 of its material (leather, iron, gold, diamond)
• Dripstone block from smooth basalt

Enchantments are lost and damage does not matter. RPack replaces the vanilla "nugget from smelting/blasting" recipes so they only cover nautilus armor (which is not craftable); otherwise two furnace recipes would compete for the same input.

Building

./build.sh

creates build/rpack-<version>+26.2.jar and build/rpack-<version>+26.3.jar. src/common holds the recipes shared by both versions, src/26.2 and src/26.3 the rest (blast furnace times are stored differently since 26.3, and poplar only exists in 26.3). tools/gen.py generated the JSON once and is kept for reference. legacy/ is the original datapack 1.3.1.

How this mod is made

Version 2.0 is written by Claude AI: the recipes, the build script and the descriptions. Konitor decides what goes in and tests every version in game. The icon is hand-made by Konitor in GIMP; no images are AI-generated.
