title: Converting child to screen space in cocos2d for android
body: <p>I am an android developer...</p>
  
  <p>currently I have 2 images, ImageA and ImageB. ImageB is a child of ImageA</p>
  
  <p>Assuming ImageA position is in (100, 100); then ImageB local position is (10, 0);</p>
  
  <p>So what I'm trying to do is how can I retrieve the screen position of ImageB whereby it will return me (110, 100) instead of (10, 0)?</p>
  
  <p>thx!</p>
