title: Anchor Point Adjustment
body: <p>I am working on trying to change the anchor point of a sprite.</p>
  
  <p>Most of the examples I have seen look something like this:</p>
  
  <pre><code>this.asset.anchor.setTo(0.5, 0.5);
  </code></pre>
  
  <p>But I am not really clear on how the this keyword is used in javascript.</p>
  
  <p>How do I adjust the anchor point of a sprite?</p>
