Lua Runtime
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Add Lua scripting to Minecraft! Still in development.
Some notes to start with
- Don't forget to check the source code of scripts as it could be malicious. We're not responsible for any bans or damages caused by scripts.
- If the game crashes due to this mod, then its probably not caused by this mod, rather caused by scripts.
- If the game crashes after updating the mod, then try deleting the config at
[Minecraft folder]/config/lua_runtime_config.json
Benefits of using the mod
- Backwards compatibility: All scripts made for older versions of Minecraft will work on newer versions of Minecraft. (breaking changes are in alpha versions)
Using the mod
Adding mods
Drag and drop Lua scripts into the lua folder in your Minecraft instance folder.
Example script
print("Hello World!")
Minecraft.AddClientLoadedListener(function()
local gui = Minecraft.CreateNewGUI("Lua Screen")
gui.Display()
end)
