title: How to make a movieclip play on a specific frame in AS3?
body: <p>I'm incredibly rusty at Flash having not touched it in probably 10 years and can't seem to figure this out, or find it online:</p>
  
  <p>I have a MovieClip with two layers, each having a Shape Tween. Basically its a Door that opens and closes.</p>
  
  <p>I dropped it onto the main timeline but now I need it to start and stop. This is where I'm now struggling since the last time I used Flash actions could go on specific keyframes.</p>
  
  <p>I made a new layer called actions just to keep things organized and currently have:</p>
  
  <pre><code>barrier1.stop();
  </code></pre>
  
  <p>I just want something that lets me state a frame, say 57 to have barrier1 start playing on. Tried using <code>play();</code> and <code>Event.ENTER_FRAME</code> with no luck. How would I set this up?</p>
