   How would I put a cpBody into a NSMutable array so that I can go through the array and update the position of each cpBody?

   You should review the sample code included with Cocos2d. The cpShape is the one the updates the position and angle of the sprite. You shouldn't have to update the position of the cpBody.

   NSMutableArray *array = [[NSMutableArray alloc] init];
   
   cpBody *body = shape->body;
   
   //Put it in the array
   [array addObject:[NSValue valueWithPointer:body]];
   
   //Pull it out
   body = (cpBody*)[[array objectAtIndex:i] pointerValue];

   @zenkimoto - it can be useful sometimes actually ;)

   True! Very True! I guess because I'm used to subclassing a CCSprite and including the cpBody and cpShape in the sprite subclass. The only issue I could see is determining which sprite belongs to which body/shape. But then again, I guess you could always use the shape->data variable...
