I am trying to give the bottom wall that is created with addWindowContainmentWithFriction a collision callback, I don't know if I am doing it wrong. This is how I have been trying to do it.
smgr.bottomWall->collision_type = kFootballCollisionType;
Am I doing something wrong because it is not responding to it. kFootballCollisionType is a collision type that I am using in other places in my code.
