title: Spritekit adding a sound effect
body: <p>I'm trying to add a sound effect to a game whenever the screen is touched. I already have a touchesBegan method that moves a character, can i put the :</p>
  
  <pre><code>[SKAction playSoundFileNamed:@"sfx.wav" waitForCompletion:NO];
  </code></pre>
  
  <p>into that method or do I need to make a new method. Also, where should I store the sound file in my project? Is there a certain place for it or can it just be anywhere?                         </p>
