I've been Googling this problem for a while now. I'm currently porting one of my Java games to Flixel, and I want to use the original 16x16 tileset I made. In the original game I implemented my own autotiling system, but I would prefer to use Flixel's autotiling system. However, I cannot determine how to lay out my tileset, or how to tell Flixel to use it. I have two different types of tiles, and I want both types to autotile to connect with tiles of the same type but not tiles of the other type, if possible.
