About

Elysium-API is a library mod for Minecraft NeoForge 1.21.1. It provides a robust collection of utilities, built-in features, and data-driven systems designed to simplify and expand the modification capabilities for both mod developers and modpack creators.

Elysium's target is to make the game easier to modify by providing tools for the more esoteric, overlooked or hardcoded parts of Minecraft; in other words, areas where vanilla behavior is often difficult or impossible to change without invasive workarounds. A few of the things it provides are:

  • Various useful Java APIs
  • Utility Classes and Methods
  • Data-driven and Resource-driven systems
  • And more!
