So im trying to make a snake enemy and im using the physics behavior and trying to connect the snakes body parts with revolute joint but for some reason it doesnt connect, so what i do is i keep the physics objects immovable at first so it cant be still while i connect the joints, then on start of layout i wait 0.1 connect all joints to eachother with revolute joint and then wait 0.1 and set all physics objects back to movable but for some reason when i set back to movable they just fall down un-connected
