title: Scaling Sprites in Cocos2d
body: <p>I'm trying to scale a sprite with "ScaleTo" and "SpriteBy" but as it's growing it's "floating away". For example let's say I have a circle, and I would like the circle to double it's radius each time it's clicked.</p>
  
  <p>Right now my circle is growing, but it looks as though the circle is scaling about the origin/bottom left corner of the sprite. I tried changing the anchorpoint to </p>
  
  <pre><code>circlesprite.transformAnchor = cpv(mysize.width/2, mysize.height/2 );
  </code></pre>
  
  <p>but that didn't work either. Any ideas?</p>
