MovieClipLoader -- totalBytes question

programming flash
1

Ok, this is bugging the hell out of me.

What I’m trying to do -seems- quite simple, but I can’t get it to work.

I’m looping through & loading a set of thumbnails using the MovieClipLoader class.

I want to have one progress bar, for the whole set of images.

The first way I thought of doing it, was onLoadStart of each image, add all the totalBytes together in a variable. ie.


myMCL.onLoadStart = function(target_mc) {
	 var loadProgress = myMCL.getProgress(target_mc);
	 myTotalBytes + bytesTotal;
}

and then do the same thing onLoadProgress for bytesLoaded, then do something like:


myBytesLoaded / myBytesTotal * 100;

as the percentage…

Which would seemingly work. BUT, even when I upload the swf, if I do a dump of bytesTotal and bytesLoaded in onLoadStart, both variables are returned as 0. As soon as onLoadProgress starts, it seems those variables become available. But not onLoadStart.

I am exporting the actionscript as v2.0 w/ flashplayer 7. The file I am loading as a test is a ~450kb jpeg.

Any ideas? I’m stumped. The MovieClipLoader class rules, but this is bugging the hell out of me.
