BCLib
A Library Mod for the BetterX Team
Quick answer
Which BCLib release matches Fabric?
BCLib 2.1.8 targets 1.19, 1.19.1, 1.19.2 with Fabric. Installation on the client is optional. Installation on the dedicated server is optional. 1 required mod needs a matching file.
Where it goes
Is BCLib required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does BCLib 2.1.8 need?
2.1.8 on Fabric. Every mod below is checked against that same setup.
Install Fabric API first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match.
We only count dependency files that match this setup. A file for another loader does not fill the gap.
Before you install it

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.
