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!

Comment installer Elysium API

With Millida Launcher

  1. Install Millida Launcher

    The launcher is free: download it at millida.net/launcher and sign in with any nickname.

  2. Click “Install” on this page

    The launcher opens and installs the mod for Minecraft 1.21.1 on NeoForge automatically.

  3. Launch the game

    A profile with it appears in the launcher: click “Play”.

Manually

  1. Install NeoForge

    The loader must match the game version of the mod file, for example Minecraft 1.21.1. After installing it, a separate profile appears in your launcher.

  2. Download the file for your version

    In the version list above, pick the file ElysiumAPI-1.21.1-2.0.1.jar (300 KB) for your game version.

  3. Put it in the mods folder

    The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it.

  4. Launch the loader profile

    Open “Mods” in the main menu: Elysium API should be in the list.

On a server

  1. A server on NeoForge

    The mod only works on a server with the same loader and game version, for example 1.21.1.

  2. File goes into the server’s mods folder

    Stop the server, put the mod file into the mods folder and start the server again.

  3. Use the “To server” button

    On Millida Hosting, the button at the top of the page uploads the file to your server and restarts it for you.

Minecraft 1.21.1 runs on Java 21: with a different Java version the game may close right after launch.
