Drag and drop puzzle in Actionscript 3

This is an update to drag and drop puzzle tutorial where I will provide the Actionscript 3 code. The steps are exactly the same in the previous Actionscript 2 version, so I will only be providing the code in this tutorial. For more information on dragging and dropping, checkout this tutorial.

//Array to hold all the puzzle movie clip instances.
var burgerArr:Array = new Array (burger_mc, burger2_mc, burger3_mc,
 burger4_mc, burger5_mc, burger6_mc, burger7_mc);

//For loop to control the drag and drop of each burger by adding a 
//mouse up and down to each movie clip.
for (var i:uint =0; i < burgerArr.length; i++) {
 burgerArr[i].addEventListener(MouseEvent.MOUSE_DOWN, drag);
 burgerArr[i].addEventListener(MouseEvent.MOUSE_UP, drop);
}

//This function drag the movie clips when the mouse is pressed.  
function drag(event:MouseEvent):void {
 event.currentTarget.startDrag();
}

//This function drop the movie clips when the mouse is released.
function drop(event:MouseEvent):void {
 event.currentTarget.stopDrag();
}
