AS3 help with Array and .visible

Hi,

I'm very new to flash so forgive me for this (most likely) silly question

I'm making a drag and drop application using some AS3 from a tutorial i found on the web:

//Array to hold the target instances, the drop instances,

//and the start positions of the drop instances.

var hitArray:Array = new Array(TargetArea1,TargetArea2,TargetArea3);

var dropArray:Array = new Array(RBatt,HAnt,GAnt);

var positionsArray:Array = new Array();

//This adds the mouse down and up listener to the drop instances

//and add the starting x and y positions of the drop instances

//into the array.

for (var i:int = 0; i < dropArray.length; i++) {

         dropArray.buttonMode = true;

         dropArray.addEventListener(MouseEvent.MOUSE_DOWN, mdown);

         dropArray.addEventListener(MouseEvent.MOUSE_UP, mUp);

         positionsArray.push({xPos:dropArray.x, yPos:dropArray.y});

}

//This drags the object that has been selected and moves it

//to the top of the display list. This means you can't drag

//this object underneath anything.

function mdown(e:MouseEvent):void {

      e.currentTarget.startDrag();

      setChildIndex(MovieClip(e.currentTarget), numChildren - 1);

}

//This stops the dragging of the selected object when the mouse is

//released. If the object is dropped on the corresponding target

//then it get set to the x and y position of the target. Otherwise

//it returns to the original position.

function mUp(e:MouseEvent):void {

         var dropIndex:int = dropArray.indexOf(e.currentTarget);

         var target:MovieClip = e.currentTarget as MovieClip;

         target.stopDrag();

         if (target.hitTestObject(hitArray[dropIndex])) {

                   target.x = hitArray[dropIndex].x;

                   target.y = hitArray[dropIndex].y;

         }else{

                   target.x = positionsArray[dropIndex].xPos;

                   target.y = positionsArray[dropIndex].yPos;

         }

What Im trying to do now is have certain movie clips become visible and others become invisible

when a movie clip from one of the arrays is dropped on its corresponding target area.

I've had a shot at it:

RBatt.addEventListener (MouseEvent.MOUSE_UP, STA1)

function STA1(e:MouseEvent):void{

var dropIndex:int = dropArray.indexOf(e.currentTarget);

    var target:MovieClip = e.currentTarget as MovieClip;

if (RBatt.target.hitTestObject(hitArray[dropIndex])) {

MovieClip(parent).RBattAtt.visible = true

MovieClip(parent).RBatt.visible = false

MovieClip(parent).A2.visible = false

MovieClip(parent).T2.visible = true

MovieClip(parent).A3.visible = true

}else{

}

GAnt.addEventListener (MouseEvent.MOUSE_UP, STA2)

function STA2(e:MouseEvent):void{

var dropIndex:int = dropArray.indexOf(e.currentTarget);

    var target:MovieClip = e.currentTarget as MovieClip;

if (GAnt.target.hitTestObject(hitArray[dropIndex])) {

MovieClip(parent).GAntAtt.visible = true

MovieClip(parent).GAnt.visible = false

MovieClip(parent).A3.visible = false

MovieClip(parent).T3.visible = true

MovieClip(parent).A4.visible = true

}else{

}

HAnt.addEventListener (MouseEvent.MOUSE_UP, STA3)

function STA3(e:MouseEvent):void{

var dropIndex:int = dropArray.indexOf(e.currentTarget);

    var target:MovieClip = e.currentTarget as MovieClip;

if (HAnt.target.hitTestObject(hitArray[dropIndex])) {

MovieClip(parent).HAntAtt.visible = true

MovieClip(parent).HAnt.visible = false

MovieClip(parent).A4.visible = false

MovieClip(parent).T4.visible = true

}

But im pretty sure that's wrong. I'm quite sure the command im using

to hide/unhide the MC's is correct. However, I think I am adressing it wrong.

Any help appreciated

Cheers
