I have a character I'm trying to keep on the bottom half of the screen. I thought I'd use a platform with it's opacity set to 0 to keep the player where I want them and that works but I want physics objects to pass through the invisible platform. In other engines I'd use layers to tell the physics object to just not collide with the platform layer. Is there a method to do that in Buildbox? Or can I clamp the players Y axis somehow?
