The test tilemap is… well a test, for making a tilemap system for 47 animation and some other things I was looking at with code. I’ll unlist that example tonight to reduce confusion. I’ve updated the current tilemaps examples to support the 47 animation version, so it would be best to use those instead.
If your game is have small levels, the auto tile system will work fine. But this system will lag if you have larger/longer levels. That is why there is also a export version (that takes a lot more work to get working). I have a Post on how to use my examples, so follow it as best you can to properly use these systems. It goes over both the auto system and the export system examples for tilemaps.
