title: Unity 4.3 2d Create Sprite Programmatically
body: <p>I'm trying my first steps with Unity's new 2d environment at the moment (coming from cocos2d). I'd love to have my game work on iOS / Android
  My question is: How can I position sprites pixel perfect / depending on screen size. E.g. have the menu button on the top left on the screen.</p>
  
  <p>I'm parsing levels from XML files. In those files the positions of each sprite are determined. Where's the best point to parse that file and how can I create my level from that file?</p>
  
  <p>Hope somebody can help! </p>
