WrapperLib

A collection of multi-platform implementations of common tasks for developing Minecraft mods. This is a tool for mod developers, it adds no content on its own. Only install it if you are using another mod that requires it.

  • Provides a uniform api across mod loaders and Minecraft versions.
  • A priority is placed on never manually writing serialization code for nbt or byte buffers.
  • Designed to be modular, so you can shadow only the parts you need and have no external dependencies.
  • Each api concept is exposed as a Builder like class with no additional setup required.
  • Extensive documentation (wiki & javadocs).

See wiki for more info.

  • NetworkWrapper: send information between the client and the server.
  • ConfigWrapper: allow players to configure mod features by editing json files.
  • DataWrapper: save extra information with world data.
  • RegistryWrapper: an api like Forge's deferred register that can be called from common code.
  • ResourcesWrapper: load information from data packs or resource packs.
  • KeybindWrapper: react to keyboard input, automatically synced to the server.
