Вставляем код в первый кадр и создаем кнопку

Stage.scaleMode = 'exactFit';
 
//Don't scale the movie when the stage size changes
//Stage.scaleMode="noScale";
//Align the stage to the top left
Stage.align = "TL";
//Function to toggle between fullscreen and normal size
//the toggle fullscreen button calls this function when pressed
function toggleFullScreen(){
	//if normal size, go to fullscreen, else go to normal size
	if(Stage["displayState"]=="normal"){
		Stage["displayState"]="fullScreen";
	}else{
		Stage["displayState"]="normal";
	}
}
//Create a listener for each time the Stage is resized
var resizeListener:Object = new Object();
//Called each time the stage is resized
 
 
 
resizeListener.onResize = function () {
	//Move the button to the center of the screen
	toggleFullScreenButton._x=Stage.width/2;
	toggleFullScreenButton._y=Stage.height/2;
}
//Add the listener to Stage
Stage.addListener(resizeListener);
 
 
Stage["displayState"]="normal";

И есть кнопка

on(press){
	toggleFullScreen();
}

Как сделать разворачивание на весь экран без кнопки?
