I want to drag square, circle and triagle and drop to any target. What code should be added? Please help.

import flash.events.MouseEvent;
import flash.display.MovieClip;

var dragArray:Array = [square, circle, triangle];
var matchArray:Array = [squareMatch, circleMatch, triangleMatch];

var currentClip:MovieClip;
var startX:Number;
var startY:Number;

for(var i:int = 0; i < dragArray.length; i++) {
dragArray.buttonMode = true;
dragArray.addEventListener(MouseEvent.MOUSE_DOWN, item_onMouseDown);
matchArray.alpha = 0.2;
}

function item_onMouseDown(event:MouseEvent):void {
currentClip = MovieClip(event.currentTarget);
startX = currentClip.x;
startY = currentClip.y;
addChild(currentClip); //bring to the front
currentClip.startDrag();
stage.addEventListener(MouseEvent.MOUSE_UP, stage_onMouseUp);
}

function stage_onMouseUp(event:MouseEvent):void {
stage.removeEventListener(MouseEvent.MOUSE_UP, stage_onMouseUp);
currentClip.stopDrag();
var index:int = dragArray.indexOf(currentClip);
var matchClip:MovieClip = MovieClip(matchArray[index]);
if(matchClip.hitTestPoint(currentClip.x, currentClip.y, true)) {
//a match was made! position the clip on the matching clip:
currentClip.x = matchClip.x;
currentClip.y = matchClip.y;
//make it not draggable anymore:
currentClip.removeEventListener(MouseEvent.MOUSE_D OWN, item_onMouseDown);
currentClip.buttonMode = false;
} else {
//match was not made, so send the clip back where it started:
currentClip.x = startX;
currentClip.y = startY;
}
}
