title: Get angle CCSprite is moving at?
body: <p>I am using SpriteBuilder with Cocos2D 3.1 and I am trying to wrap my head around the logistics of this. What I want to do is get the angle the sprite is currently moving at based upon a X and Y velocity from my Chipmunk physics.</p>
  
  <p>Those values are easily attained by:</p>
  
  <pre><code>sprite.physicsBody.velocity.x
  sprite.physicsBody.velocity.y
  </code></pre>
  
  <p>Now would I use atan2 from here? I am also confused about the axis that CC_DEGREES_FROM_RADIANS is returned in. If anyone can shed some light on this trivial issue I am having, that would be swell!</p>
