[flashpro] AS2 Preloader - - Help Needed...

[Matthew Zoern]

Hey Fes,

If you want your preloader to fade in then out you need to set it up in 
a movie clip. You have a transition in on the loader. The loader 
activates and when you've reached your desired percent loaded you fade 
back out.

There is a couple ways you can fade this back out. You can set up a 
function to set back frame by frame to the beginning of the clip. In 
essence faking the transition back out.

The other way is simply doing the same fading in. then fading the clips 
out using the timeline.

I'm not sure the best way to do this using AS2.0, but I'll put this out 
and see if anyone has any modifications or better ways of doing it.

// Code begins here

this.onEnterFrame = function(){
	maxBarWidth = statusBarMain_mc._width;

//	reads the size of the document and divides it by what has been loaded
	percentloaded = _root.getBytesLoaded() / _root.getBytesTotal() * 100;
	display_txt.text = Math.round ( percentloaded ) + "%";

//	the width of the bar is set based on the "percentloaded" variable
	currentBarWidth = percentloaded;
	statusBarMain_mc.bar_mc._width = (currentBarWidth / 100) * maxBarWidth;

//	checks to see if the swf is 100% loaded
	if (percentloaded >= 100) {
		_root.gotoAndStop("start");
		delete this.onEnterFrame;
	}
}

// Code ends here
