What It Does:
Keeps an object within the frame of the camera at all times.
How to Use It:
Reaction - Determines how the object will react once it hits the edge of the screen.
Wrap Around - The object will reappear on the opposite end of the screen.
Stop - The object will lose all velocity and remain at the edge.
Reflect - The object will reverse the direction of its movement.
Collide - The object will lose some velocity and bounce off as though running into a wall.
Padding - Refines where the edge of the frame for this object will be.
