Oh, thats disappointing. Still neat to add a LUA mod loader to Minecraft, and will probably help those coming from other games that use LUA, but given that Minecraft is already written in easily-decompiled Java, and has a separate API for simpler mods/scripts (datapacks) still feels kind-of redundant.

From my understanding, this is a lot more powerful than anything Luanti normally offers. Its not server-side modding (Minecraft has obviously had that for ages), its a full LUA interpreter with an in-game interface for clients to write scripts, and upload them to the server on the fly.

Edit: I was wrong, its just a mod loader running entirely server-side, without a way for clients to interact with it, so it basically just adds the ability for the server to run LUA scripts alongside other Java mods and datapacks.
