The 3 mentioned in the first post are Civ 5, Garrys Mod and ComputerCraft, I’ve also mentioned ToME but I didn’t see that on the list, there’s a few things out there.
Good news everyone!
FIRST REMEMBER: The graphics demo could have significant changes to the actual release, there might even still be major changes to the modding api.
Now though that we have a kind of crippled demo of the Stonehearth engine, this demo contains two ‘smod’ files in the mods folder that likely contain all the lua. My initial instincts were correct on them and they’re actually just renamed zip files. After quickly extracting them it revealed they had a whole load of luac files there seems to be a whole bunch of lua decompilers across the web however I couldn’t get one working. I have confirmed though that modifying the json works fine based off my teleporting bunnies.
Just throwing that out there.
