title: About Collision detection alghorithms in AS3
body: <p>Ok. So there are several methods to implement Collision detection like R-trees, Quadtrees, BSP trees Recursive Dimensional Clustering (RDC). Or maybe more.</p>
  
  <p>My problem is that I have about 6-8 enemies on stage, some of them moving some of them static and also I have the Hero who is shooting with three types of missiles at same time. So I get about 70-100 objects on stage at a time.</p>
  
  <p>My question is, which algorithm to use for this type of problem, and which is the common practice? Also which is the most efficient?</p>
  
  <p>I was thinking of implementing Quad trees but I read that thy can be slow, or I am wrong?</p>
  
  <p>ps: Can I use Octal trees or they are strictly for 3D?</p>
