Flash Preloader as3

Is it possible to set total bytes in an as3 preloader? I'm not sure it's correct, but to avoid an infinite loop I've done this.

var loadper:Number=0;
var total_bytes:Number = 3484484;
loaderInfo.addEventListener(ProgressEvent.PROGRESS, loader);

function loader(filename:ProgressEvent) { 
   var loaded_bytes:Number = stage.loaderInfo.bytesLoaded;
   _txt.text=String(loadper+"%");
   if(loadper>=100) { 
      preLoader_mc.perct_mc.visible=false;
      loaderInfo.removeEventListener(ProgressEvent.PROGRESS, loader);
   }
}

In the same event there is the information about total bytes.

You can have it as 

filename.bytesTotal

where filename is your event variable as per your code.

By doing

filename.bytesLoaded / filename.bytesTotal

you have the percent completion. This would never enter an infinite loop.

You can check more detailed information on adobe's documentation and examples here.

Just listen out for Event.COMPLETE which triggers once the file has fully loaded. Along with a few other tweaks:

loaderInfo.addEventListener(ProgressEvent.PROGRESS, loaderProgress);
loaderInfo.addEventListener(Event.COMPLETE, loaderComplete);

function loaderProgress(event:ProgressEvent) { 
    var percentage:Number = Math.round((stage.loaderInfo.bytesLoaded / stage.loaderInfo.bytesTotal) * 100);
    _txt.text = percentage + "%";
}

function loaderComplete(event:Event):void
{
    loaderInfo.removeEventListener(ProgressEvent.PROGRESS, loaderProgress);
    loaderInfo.removeEventListener(Event.COMPLETE, loaderComplete);

    preLoader_mc.perct_mc.visible = false;
}
