Fastest Type Comparison?

Question

The following event can possibly get called hundreds of times a frame.

public bool OnCollision(Body body1, Body body2)
{
 if(body2.Tag is Dog)
      ((Dog)bo         


        

Answer 1

How about a generic collision method? Then there is no need for inheritance. Just an interface.

public bool OnCollision(TA a, TB b)
    where TA : ICollidable
    where TB : ICollidable {
    a.Collision(b);
}
