title: Only Integrating Box2D collision detection in my 2d engine?
body: <p>I have integrated box2d in my engine, ( Debug Draw, etc. ) and with a world I can throw in some 2d squares/rectangles etc.</p>
  
  <p>I saw <a href="http://www.box2d.org/forum/viewtopic.php?f=3&amp;t=3952" rel="noreferrer">this</a> post, where the user is basically not using a world for collision detection, however the user doesn't explain anything about how he's using the manifold (b2Manifold), etc.</p>
  
  <p><a href="http://www.cocos2d-iphone.org/forum/topic/2692" rel="noreferrer">Another post</a>, is in the cocos2d forum, ( scroll down to the user Lam in the third reply )</p>
  
  <p>Could anyone help me a bit with this?, basically want to add collision detection without the need of using b2World ,etc etc.</p>
  
  <p>Thanks a lot!  </p>
