I need to collect data on what each tile is in tilemaps in order to remake the tilemaps later and perform a few operations on them. I also need to do this for how many ever tilemaps are in a room. Given that I have the data on which tilemaps exist in the room how do I store what each tile is, and for multiple tile layers (I know GM doesn't do 3d arrays). If even if you can only explain storing the individual tile data on one tilemap that you already know exists that may be helpful. Since the tiles will be numbers in the data reading it may be difficult unless arranged like xy cells, and how to do I order these number in a manor that looping through them will produce the tilemap again?
