title: combining multiple CCSprites into one grouped object in cocos2d
body: <p>I wonder what's the best approach to combine several CCSprites dynamically into one grouped object using cocos2d.</p>
  
  <p>I have to dynamically create characters from a set of multiple CCSprites. The elements can't move relative to each other after combined - and are never separated again. </p>
  
  <p>When combined they should behave just like one CCSprite in terms of moving and turning etc.</p>
  
  <p>I couldn't find anything in cocos2d, or do I have to use a physics engine just to achieve this? I am afraid, using Box2d (without experience) creates a lot of additional coding overhead and effort. </p>
  
  <p>Many thanks</p>
