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.
right now theres just a moving ball, inside a box, with a working paddle. i had to make the ball kinematic and tell the ball to bounce when it hits the other direction.
