Collision System Revisited

After giving a lot of thought to Professor Keenan's suggestions about callbacks and the decoupling of colliding objects, I have decided to completely redesign my collision system and generalize it to the point that it could become a central part of my MHFramework game engine.

Here are the elements of the system as I am currently envisioning it:

Collidable Interface

• public boolean isColliding(Collidable);
• public CollisionGeometry getCollisionGeometry();
• public void collideWith(Collidable);
• public int getType();

CollisionPoint Class

• private Point center;
• private float radius;
• public boolean isColliding(CollisionPoint);

CollisionGeometry Class

• private ArrayList collisionPoints;
• public boolean isColliding(CollisionGeometry);
• public CollisionPoint getCourseBounds();
