title: Simple Gif like animation with Spritekit
body: <p>I can't really find a simple solution for this, every example I see only shows very complex solutions, but all I want is 2-3 images that cycle so it appears as if it is animated. Same effect as an animated Gif.  For now I have this to create an image  </p>
  
  <pre><code>MonsterNode = SKSpriteNode(imageNamed: "MonsterNode_GameScene")
  </code></pre>
  
  <p>but how would I set MonsterNode variable to an animation of this sort? I am really looking for the very least amount of code needed to achieve this. </p>
