[Flashcoders] showing code progress with progress bar

2008-11-21 Thread Mac Angell 
Is it possible to show the progress of a code loop on a progress bar?
For example, if I have a progress bar named pbar already defined on
the stage, and I execute the following function:

 

private function init():void

{

  var total:int = 10;

  for (var i:int = 0; i  total; i++)

  {

pbar.setProgress(i, total);

stage.invalidate();

  }

}

 

The progress bar jumps from 0% to 100% after a long pause (the for loop
executing). I am pretty sure this happens because the entire code loop
executes before the next frame gets rendered. As you can see I even
tried stage.invalidate(), but my guess is that it just tells the stage
to update on the next frame, instead of forcing the stage to update at
that exact time.

 

Is there any way to get this to work in AS3? In other words, is there
any way to force the screen to update in the middle of a code thread?

 

Thanks!

Just simulate a for loop with an ENTER_FRAME listener.

var total:int = 1;
var i:int = 0;
root.addEventListener(Event.ENTER_FRAME, simLoop);
private function simLoop(e:Event):void
{
  if(i = total){ root.removeEventListener(Event.ENTER_FRAME, simLoop); };
  pbar.setProgress(i, total);
  i++;
}

Yikes! I don't think he actually wants the loop to take any longer than
necessary. I'm assuming he's got some sort of computationally expensive
operation (huge parse or something) that he wants to show the progress. How
about subdividing your loop into more manageable chunks that get called once
a frame?

Hi,

the onenterframe will work, but you can approach it a little
differently, in pseudo:

onEnterFrame {
 if (no items to process left) { clear onEnterFrame, signal done; }
 set loop start time
 while (currenttime - loop start time  100 ms) {
   process loop item
 }
 update progressbar
}
