Question
There is a lot of info how to make alternative tiles and randomly placed tiles, but I couldn’t find anything about autotile specifically. So I had to figure this out on my own, and I want to ask if this is good or horrible approach.
Once you have your complete tileset with 47 tiles, you can add more tiles to it, and if you paint (the terrain paint) those extra tiles with the same pattern as the existing ones (to basically make duplicates of previous tiles), tilemaplayer will detect it as part of the autotile, and start to place it randomly (with assigned probability).
