I have three sprite objects. All have physics behavior. Sprite 1 and 2 are squares and are movable. Sprite 3 is used for walls and immovable. When Sprite 1 and Sprite 2 "collide" with each other, I don't want them to. I want either Sprite 1 or Sprite 2 to be passable to that just go right through each other but still react and collide with Sprite 3. It seems as if all sprite objects with physics behavior are solids and impassable by other physics objects? What can I do?
I've tried numerous things and search the forums in a ton of different ways. Please help.
