title: Loading sprite sheet with EaselJS
body: <p>Being new to EaselJS, I've used the code from the "Simple Sprite Sheet" example that's packaged with the source zip file.  I'm trying to get a sprite sheet to load and play through, but only the first frame appears.       </p>
  
  <pre><code>function init() {
      var stage = new Stage(document.getElementById("canvas"));
      var ss = new SpriteSheet({
          "frames": {
              "width": 159,
              "numFrames": 71,
              "regX": 0,
              "regY": 0,
              "height": 85
          },
          "animations":{
              "instance1": [0, 0], 
              "images": ["./assets/spritesheet.png"]
          });
  
      var animate = new BitmapAnimation(ss);
      animate.x = 0;
      animate.y = 0;
  
      ss.getAnimation("instance1").frequency = 2;
      ss.getAnimation("instance1").next = "instance1";
      animate.gotoAndPlay("instance1");
  
  
      stage.addChild(animate);
      Ticker.setFPS(60);
      Ticker.addListener(stage);
  }
  </code></pre>
  
  <p>I don't think I need a ticker function because I'm not registering any events, I'm just playing from instance1, the frames and canvas are both of equal size and the animation plays through if I substitute <code>animate.gotoAndPlay("instance1");</code> with <code>animate.play("instance1");</code>, but loops.  Any suggestions?  Thanks in advance.  </p>
