Currently the focus of the GameMaker export has been on matching the level visually and allowing objects to be instantiated. Actually I haven’t used GameMaker beyond a few short sessions to make sure this part of the export works as expected.
So the question is, how is collision generally done in GameMaker and what should Tiled export to enable a comfortable integration? Eventually I could have a look myself, but if you already have some experience with this any insights would be very appreciated.
