Collision groups and mask? I have 2 objects that collide, how do I have one of them not collide with anything and still be dynamic? My two objects are a body and a controller, I want the controller to be dynamic so it can fall, but not interfere with bullets; moreover, I want my character to be static so it can collide with bullets.
For the controller, check the Ghost option under the physics tab. This will cause the object to still fall, but there won't be any collisions. You can also parent the character to the controller without having do a major freak-out.
