Lua threads are separate environments and so they cannot access the variables and functions of the main thread, and communication between threads is limited.
They are to be used for for loops, io loading/saving, multiplayer, physics etc.

Is it okay to post in Games and distribution without providing a link to your game? (sort of like a dev log?)

That's what mine does too, kinda. And some extra transformation to make isometric work.

Not sure what "blit" means, I'm not native english and google translate says nothing about it. Anyways, that really does sound like a lot of work, and I already implemented a depth sorting. It uses a skip list and it's O(log(n)) insertions, deletions and search, and O(n*log(n)) space usage...

I'm not sure if I understood you correctly or you me,but I was referring to the functions. Or are they also stored in _G (when they're not declared local)

Yeah, I will only sort when a new object is added to the table. I'll just loop through the sorted using a for loop or something to draw it. How can I get the size of the table? Or should I make a variable to keep track of it? I tried table.setn table.getn which is in the lua manual but doesn't seem ...

Yeah, I know, the title kinda breaks the rules but I didn't know how to name this topic. So I'm making an isometric RTS and so far, I've got the terrain set up only. https://love2d.org/imgmirrur/heTEuT0.png I'm using spriteBatch for the tiles and I update the spriteBatch only when I update the terra...

Is that better than making it global, performance wise? (I know it's splitting hairs, just curious)
