DUPLICATE CLIP IN AS3

Firstly we need to create duplicate display object

duplicateDisplayObject.as

package {

import flash.display.DisplayObject;
import flash.geom.Rectangle;
import flash.system.Capabilities; // version check for scale9Grid bug

/**
* duplicateDisplayObject
* creates a duplicate of the DisplayObject passed.
* similar to duplicateMovieClip in AVM1. If using Flash 9, make sure
* you export for ActionScript the symbol you are duplicating
* @param target the display object to duplicate
* @param autoAdd if true, adds the duplicate to the display list
* in which target was located
* @return a duplicate instance of target
*/
public function duplicateDisplayObject(target:DisplayObject, autoAdd:Boolean = false):DisplayObject {
var targetClass:Class = Object(target).constructor;
var duplicate:DisplayObject = new targetClass() as DisplayObject;

// add to target parent's display list
// if autoAdd was provided as true
if (autoAdd && target.parent) {
target.parent.addChild(duplicate);
}
return duplicate;
}
}

doubleRed.as class

package {
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.display.Graphics;
import flash.display.Sprite;
import flash.geom.Rectangle;
import flash.geom.ColorTransform;
import flash.display.MovieClip;


public class doubleRed extends Sprite{
public function doubleRed()
{
graphics.beginFill(0x00ff00);
graphics.drawCircle(50,50,15);
graphics.endFill();
}
}
}


After it we just need to make a document class and its done!!!!!!!!!!!!
