title: Cocos2d getChildByTag between multiple CCSpriteBatchNodes
body: <p>I am creating a game that requires multiple CCSpriteBatchNodes. </p>
  
  <p>How do I communicate between the separate batch nodes using <code>getChildByTag</code> Whenever I used the <code>(GameCharacter *)[[self parent] getChildByTag: tagName]</code> I will only work for one class at a time.</p>
