What it does

B100Lib is a library for other mods and does not change the game on its own. Its code is open source under the MIT License, and Bestsoft100 publishes it for Fabric only, with files for 26.3 as the newest release. It is a client-side only mod, so players install it and servers do not need it. Fabric API is required, and Mod Menu is optional.

Key features

  1. Library for other mods

    Other mods can depend on B100Lib to reuse its shared code instead of bundling their own copy.

  2. Settings screen

    An extra screen is opened from the Mod Menu list, giving players a place to view the library's options.

  3. No changes to gameplay

    Installing the library leaves vanilla mechanics alone until a mod that depends on it adds content.

What the author says

For now I would recommend against other people using it in their mods as I might make breaking changes, but it is MIT licensed, so you can take code if you need anything.
