Percentage preloader

From Flash Wiki

Creating a preloader is easy!!! The easiest one is:

• Make a dynamic text field with an instance name of preload.
• Use this ActionScript:

   stop();
   
   if(getBytesLoaded() == getBytesTotal()) {
       play();
   }
   preload.text = Math.round(getBytesLoaded()/getBytesTotal()*100)

• Explanation: It stops the timeline, and if all the bytes that have been loaded equals the total number of bytes, play the rest of the timeline.
