I'm using https://github.com/Kadoba/Advanced-Tiled-Loader/wiki to handle map loading from Tiled, but I'm having difficulty getting the coordinates of individual tiles.

I had planned to iterate through every tile and check for but I can't pull the tile.x or tile.y coordinates from the class.
How do I grab the tile coordinates.. or is there a better way of handling collision using ATL?

I'm not entirely sure I understand the problem, could you attach a .love file? If the problem is finding a certain tile's x,y coordinates, couldn't you iterate through a loop in a load function and use that as the "map coordinates" for your collision reference?
