Hey, I am hard at work on my game "Space Cat" and I have some questions about one way collision on tilemaps. Like, is there a way to do this without making the one way colliding tiles into immovable objects (which I assume isn't TERRIBLE, it still uses the quadtree but it has to update more variables). I have a collision tilemap in two layers, one with "ground" and "walls" and one for one way platforms. The problem is how the tilemap body is handled isn't super clear. I was thinking of writing an extension of the collide function to specifically deal with this. Any help would be groovy.
