i added a GameArea class which makes it easier to operate on in coordinates bounds with the GameCoordinate struct wrapper which does calculations for me. the GameArea class also has a normalization system which is how the ScalingManager can teleport items in bounds to relatively the same place when resized. it took quite a while to get the paddle to teleport. looks like im supposed to modify the position inside IntegrateForces instead of PhysicsProcess which is my mistake.
