Cotton is a general-use, public library for unity within Fabric mods. Currently, it adds:


  • Block and metal unification (no more having to juggle six types of copper ingot)
  • Common item tags that vanilla doesn't include
  • Configuration (temporary until Fabric's system is complete)
  • Logging using Log4j
  • Auto-generation of loot tables and data tags when necessary (primarily dev tool)
  • Removal of existing recipes without log spam (primarily dev tool)
  • Cauldron behaviors API (like filling a water bottle or brewing) with LibCD tweaker support
