Install World Weaver, Fabric API first. We found matching files for this game-version and loader setup. 1 comes through another mod in the chain.
1 extra mod was pulled in by another dependency. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does BCLib add?
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.
