Im trying to create a preloader that calculates total bytes across all loaded movies. Does anyone have any links to a good tutorial or source FLA on the matter? Or look below and give a hint or two.

Thanks!

Im doing something like this:

one frame 1:

onClipEvent (load) {  
&nbsp &nbsp &nbsp &nbsp loadMovieNum(“home.swf”, 1);  
&nbsp &nbsp &nbsp &nbsp loadMovieNum(“profile.swf”, 2);  
&nbsp &nbsp &nbsp &nbsp loadMovieNum(“navigation.swf”, 20);  
}

on frame 2:

onClipEvent (enterFrame) {  
&nbsp &nbsp &nbsp &nbsp totalBytes = \_level1.getBytesTotal()+\_level2.getBytesTotal+\_level20.getBytesTotal();  
&nbsp &nbsp &nbsp &nbsp bytesLoaded = \_level1.getBytesLoaded()+\_level2.getBytesLoaded+\_level20.getBytesLoaded();  
&nbsp &nbsp &nbsp &nbsp percentLoaded = Math.floor  
if (percentLoaded\>0 && percentLoaded\<100) {  
&nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp \_root.text=percentLoaded+" %";  
&nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp \_root.loadingbar.gotoAndStop(percentLoaded);  
&nbsp &nbsp &nbsp &nbsp }

&nbsp &nbsp &nbsp &nbsp if ((totalBytes\>100) && (percentLoaded \>= 100)) {  
&nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp \_root.gotoAndPlay(“loaded”);  
&nbsp &nbsp &nbsp &nbsp }
