Today’s patch combines a couple of things together to make a fun time-waster. The important thing to note are the bodies using @kinematic 1. This prevents the physics of other bodies from knocking those objects around. This is useful for things where you want to control exactly where they are and move them around. With @kinematic 1, the moving walls can actually kick things around a little when they move too. I couldn’t help throwing in a little GL Camera feedback in the backdrop for good measure.
