sys_collide Detect collisions between static and dynamic colliders. Collision detection is done using axis-aligned bounding boxes (AABB). Static vs. dynamic collision detection is O(n*m). All dynamic colliders are checked against all static colliders. This works great for a small number of dynamic colliders and a large number of static colliders. Dynamic vs. dynamic collision detection is O(n^2). All dynamic colliders are checked against all other dynamic colliders. This can become very expensive if there are many dynamic colliders. In general, fewer than 100 dynamic colliders is recommended. Static vs. static collisions are not checked at all.
