Set Multiple Properties

// set multiple properties of an Object 
function setProps(o:*, props:Object):void{
	for (var key:String in props){
		 o[key] = props[key];
	}
}

// example: 

var s:Sprite = new Sprite();
s.graphics.beginFill(0);
s.graphics.drawRect(0,0,10,10);
addChild(s);

// set some properties
setProps(s, {x:100, y:100, scaleX:2, scaleY:2, rotation:45});

This was inspired by tweening engines like TweenLite.

Basically the same thing using a with statement:

with(s) x = 100, y = 100, scaleX = 2, scaleY = 2, rotation = 45;
