Hey there! This isn't exactly a 2D Toolkit question, but I am using the polygon mesh colliders that the sprite collection tool generates.
In our game, we use hand-painted backgrounds for our levels instead of tiles. The walls/edges of our levels are often curvy, so we want to outline the background art with polygon mesh colliders and have a CharacterController attached to the main avatar so that it will slide nicely against the walls.
So far, this works perfectly on the x-axis. If you approach a diagonal wall horizontally the avatar will slide appropriately, but vertically, the avatar will stop dead in it's tracks. I'm not sure why this is the case.
Any advice or insight is greatly appreciated. Thanks!
