I have checked the database about 5 times to make sure that these certain tiles aren't passable. But once I launch the playtest of the game I can go right through them no matter what I do in the database.
I had the same problem a while ago....
did you try opening a new project and testing pass abilities in that?
if they do work, then theres a problem with your system file in data
what i did to solve the problem was overwrite my original system file with a new one from another project....
if im not clear enough, let me know, hope this helped : P
I'll give it a shot. I did manage to temporarily fix it by moving the tiles to a different layer.
I had that problem also, but nothing seemed to work. All properties in tileset database were correct and the problem was still there.
So i deleted the trobled map completely and started it over again, and magically the problem was gone. I think it is specifical of the map. Try deleting and making a new one and see if it works it did for me as long as there were no more troubled maps in the game.)
