OK, i’ve been wondering this for quite some time now… how can i test a preloader… if i have an animated preloader, and want to make shure that everything works? It’s such a small swf that i can’t see if the preloader is doing waht it’s supposed to!

:ear:

this is the AS i’m using

load\_mc.onEnterFrame = function(){  
var getPercent = \_root.getBytesLoaded() / \_root.getBytesTotal();  
var goFrame = Math.round(getPercent \* 50);  
this.gotoAndStop(goFrame);  
if (goFrame == 50) { // preloading finished  
\_root.nextFrame();  
}  
}
