onLoadInit alternatives

Hi,

I have a preloader here that works great, but I would like to change one part
of the code…

I am using ‘onLoadInit’ to declare some actions as soon as the movie is loaded, but I want those actions to start when the movie is loaded to 80 % because the movie has an intro that will gain me some time to load the rest…

here’s the part of code that I want to change:

myListener.onLoadInit = function (target:MovieClip){
		_root.gotoAndPlay("sections");
		_root.container.play();
		trace ("Loaded!!!!");
		loader_2.loadbar._visible = false;
	}

What are my options to replace ‘onLoadInit’ with something that I have more control over the load progress ?

As always, thanx for your help in advance !!!

Mike
