Havok Tutorial: A way to detect bullet collisions

Hey. This will be less of a tutorial and more of a "here's a way to do something".

One way you can detect your bullets hitting objects in Havok is through the use of Phantoms. These are aabb's that exist simply to report what collides with them (and to apply events to those colliding objects if you'd like). This makes Phantoms great for things like triggering events based on a player's location, and bullets.

Check out the demo at: Demo\Demos\Physics\Api\Dynamics\Phantoms\PhantomObject for example code on using Phantoms.

So for example, you can draw your bullets as particles, and maintain a phantom for each of these bullets. When a bullet phantom's collision list contains an enemy you can say doBulletHitEnemy() or whatever.
