title: Trouble with getChildByTag (cocos2d iPhone)
body: <p>I have a scene called Level1, which takes the hero and the enemy  from a layer called GameLayer. I heard that an efficient way of doing this is using tags and retrieving it using getChildByTag. I tried this out, but I'm having many issues. I'm using SneakyInput. On Level1, there is a leftJoystick (for enemy movement), and a rightJoystick (for firing projectiles). I have an addEnemy and addHero method in my GameLayer, which I call. Everything I've mentioned works.</p>
  
  <p>In my Level1 scene I have a method called moveHero (which obviously is supposed to move the hero with the joystick.). Through basic debugging I know the problem is the geteChildByTag line. I test out the hero's position through NSLog, and it's saying 0,0. Which is weird because on screen you can see the hero. But I also realized I'm calling the addHero method without using getChildByTag.</p>
  
  <p>I hope I'm being clear here. I've uploaded GameLayer.h and GameLayer.m onto 4shared. <a href="http://www.4shared.com/file/PqhjoMFy/GameLayer.html" rel="nofollow">http://www.4shared.com/file/PqhjoMFy/GameLayer.html</a></p>
  
  <p>Hopefully you can take a look at it and point me in the right direction.</p>
  
  <p>BTW: There are no errors or crashes. It's just not working.</p>
  
  <p>Thanks in advance.</p>
