colorTransform update

[davivid]

I cant seem to update the color of some simple graphics, which has me pretty stumped now.

	import flash.geom.ColorTransform;
	import flash.display.*;
	import flash.events.*;

public class objects extends Sprite {
		public var bigSquare:Sprite = new Sprite();
		public var smallSquare:Sprite = new Sprite();
		
		
		public function objects():void {
			bigSquare.graphics.beginFill(0x2c6ccc); 
			bigSquare.graphics.drawRect(20,50,200, 200);
			
			
			smallSquare.graphics.beginFill(0x4cc5cc);
			smallSquare.graphics.drawRect(300,170,100, 100);
			
			addChild(smallSquare);
			addChild(bigSquare);
			
		}
		
		public function changeColor(object, color:uint):void {
			
			 var colorTransform:ColorTransform = bigSquare.transform.colorTransform;
             colorTransform.color = color;
             bigSquare.transform.colorTransform = colorTransform;
			 trace(colorTransform.color);
			 bigSquare.x = 500;
			
 			
		}
	}

when the changeColor function runs I get the trace output showing the selected color, however nothing happens to the graphics. I even added the line bigSquare.x = 500 to see if that had any effect but nothing. What am I missing?? thanks.

You need to create a new Colortransform instance, which you are not doing. here is the corrected script:

public function changeColor (object:Object, color:uint):void
{
    var colorTransform:ColorTransform = new ColorTransform();
    colorTransform.color = color;
    object.transform.colorTransform = colorTransform;
    trace (colorTransform.color);
}
