Collision Detection :
All game objects, such as bunnies, enemies, and fences, have an axis-aligned bounding box (AABB). A bounding box is scaled with the dimensions of its object and adjusted to fit its object when its object is rotated. The bounding boxes are used for collision detection between game objects. Collision detection with the boundary of the world is simplified through the use of larger bounding boxes representing the sides of the world.
