About this Mod
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.

BCLib server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors.

BCLib officially supports fabric for Minecraft 26.3-snapshot-6, 26.2, 26.1.2. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with BCLib – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if BCLib consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
