title: Make a movieclip remove all of it's children
body: <p>How do I remove all children of a movieclip?</p>
  
  <p>I tried</p>
  
  <pre><code>while(radar.numChildren &gt; 0){
      radar.removeChildAt(0);
  }
  </code></pre>
  
  <p>but this causes the movieclip graphic itself to be removed.</p>
