public class CollisionBox extends Rectangle implements CollisionArea, PositionChangeListener<CollisionBox>, SizeChangeListener<CollisionBox>
Rectangle that allows for interpolation. Game
objects can use this class to move around the game world and retrieve the
appropriate rendering coordinates during the render phase.geometry, positionChangeListeners, sizeChangeListeners| Constructor and Description |
