@mindfaQ Perhaps I should've posted this in the beginner section as I have no idea how to store in project files + ajax, let alone tilemaps. I'll take a look at some ajax tutorials. Thanks!
What I am aiming to do once I figure out how to do it:
1. Store tilemap in project files + ajax
2. When level is beaten, make a loading screen and load the next sequence of tiles (using the same tilemap) from ajax files.
I'm guessing I'll have to store the corresponding number of the tilemap into the ajax file and I guess they are ordered 0,1,2,etc...? Then I'll have to store the order of the tile map from left to right, top to bottom. Could be 5,0,0,2,3,etc..., then store them in the ajax file, then recall them using arrays?
