A Library Mod for the BetterX Team

Product

About

BCLib is primarily a mod library for BetterEnd, BetterNether, Eden Ring and possible future mods from the BetterX team.

Furthermore, BCLib creates compatibility between different Nether/End mods. This allows Biomes from different DataPacks and mods to generate in your world. For this (and many other features) BCLib uses its own world type: BetterX.

The library can be used by other developers to create their own mods. If you have suggestions or extensions, we are open to discussions and pull requests.

Key Features

  • Block templates for common types (plants with seedlings, wood types, signs, ...)
  • Simple API to create your own biomes, features, structures and much more
  • SurfaceRule/MaterialRule registry. This makes it possible for mods and datapacks to define additional SurfaceRules/MaterialRules for a dimension without editing/copying the vanilla rules.
  • API to create own world types
  • Manage tags
  • Simple UI layout toolkit
  • Recipe management
  • SDF tools
  • Config system with automatic synchronization between client/server
  • Manage world specific data
  • And many smaller extensions like color helper, block/item management, world patchers, etc.
