About the Lodestone mod

Lodestone is a library used by all mods under the Lodestar team, containing important backend code mostly used for rendering.

Features:

A lot of shaders Various helper classes & utilities A simple screenshake implementation Some commonly used attributes in our mods A system allowing for custom fire effects applied to entities A particle system with a huge amount of per-particle configuration A simple system for multiblock structures & block entity inventory handlers A system for onscreen GUI-side particles with similar configuration to our other particle system A world event system, similar to entities but saved, rendered, and ticked per dimension, rather than per chunk A texture loader implementation; allowing for duplicating vanilla assets at a new directory during runtime.

How to install Lodestone

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 1.20.1–1.21.1 on Fabric, Forge or NeoForge automatically, together with its dependencies: Fabric API, Dependency.

  3. Launch the game

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

Manually

  1. Install Fabric, Forge or 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 lodestone-1.21.1-1.8.2.jar (800 KB) for your game version and loader.

  3. Put it in the mods folder

    The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it. Required dependencies go there too: Fabric API, Dependency.

  4. Launch the loader profile

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

On a server

  1. A server on Fabric, Forge or 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.
