Stop your dirty thoughts right now!
Now seriously... to the topic. I'm wondering how the collision algorytm works from the perspective of collision bounding box.
1. Does size of the collision elements/bounding boxes matter? And if so then is it faster when the object is bigger or smaller?
2. Does C2 calculate collisions faster if bounding box is rectangualr (4 points, 90 degrees) shape rather then some fancy (many points) shape?
