Set Multiple Properties

CLICK HERE TO COPY
Actionscript:

// set multiple properties of an Object

function setProps(o:*, props:Object):void{

}

 

// 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.

I had either totally forgotten about or never known about the Number, uint, int etc... .toString() radix argument. Brock mentioned it to me in conversation and I've been having fun with it ever since. It's especially nice for tracing out hex numbers:
