This is a library mod for BetterEnd, BetterNether, Eden Ring and possible future mods from BetterX team. It should be installed as a separated mod.

This library can be used by other developers to make their own mods. If you have some suggetions or enhancements we are open for discussions and pull requests.

Some features will appear in future, all documentation is inside javadocs. If some docs are missing please report this, it will be fixed.


Standalone Features:

  • Compatibility between Nether and End mods and datapacks biome generation
  • Emissive textures (with "_e" suffix) for solid and cutout blocks (+ resourcepack support; will not work in Iris);
  • Automatic emission shaders for Canvas (+ resourcepack support);


Modmakers Features (short outdated list):


  • Emissive textures (with _e suffix)
    • Can be applied to Solid and Transparent blocks;
    • Can be changed/added with resourcepacks;
    • Incompatible with Sodium and Canvas (just will be not rendered);
    • Incompatible with Iris shaders (Iris without shaders works fine).
  • Procedural block and item models (from paterns or from code);
  • Block render interfaces.


  • Simple Mod Integration API:
    • Get mod inner methods, classes and objects on runtime.
  • Structure Features API:
    • Sructure Features with automatical registration, Helpers and math stuff.
  • World Data API:
    • World fixers for comfortable migration between mod versions when content was removed;
    • Support for Block name changes and Tile Entities (WIP).
  • Bonemeal API:
    • Add custom spreadable blocks;
    • Add custom plants grow with weight, biomes and other checks;

  • Weighted list:
    • A list of objects by weight;
  • Weighted Tree:
    • Fast approach for big weight structures;
  • Block helper:
