   I was browsing the Box2D examples and I noticed that in the Ray-Cast Example nothing happens... is there a reason?

   yes, some box2d samples, like the RayCast sample, contain OpenGL commands (not OpenGL ES commands). So, those commands were commented, otherwise it those samples won't compile. The correct fix is to replace the OpenGL commands with Box2d draw commands.

   @steg90, thanks for the quick reply... I've gone through the link!

   It helped me to understand the concept of raycast. Even though still i have some uncleared doubts! Please help me out to get it.

   How to Initialize it?

   Callback for raycast?

   RayCast is available for world and the fixtures! Which one i have to use?

   If you have any sample project or link please post it!

   Thanks

   :D
