Can I get some tips With My Inventory system for my game. I want to use an object in my inventory with another object (like a Key to a Door) - actionscript-3

Question

This is my Main Class:
package {
import flash.display.*;
public class InventoryDemo extends MovieClip {
var inventory:Inventory;
public function InventoryDemo() {
}
public function initialiseInventory():void
{
inventory = new Inventory(this);
inventory.makeInventoryItems([d1,d2]);
}
}
}
I used a sprite indicator to show that the items are inside the inventory.
And this is my child class:
package {
import flash.display.*;
import flash.events.*;
public class Inventory
{
var itemsInInventory:Array;
var inventorySprite:Sprite;
public function Inventory(parentMC:MovieClip)
{
itemsInInventory = new Array ;
inventorySprite = new Sprite ;
inventorySprite.x = 50;
inventorySprite.y = 360;
parentMC.addChild(inventorySprite);
}
function makeInventoryItems(arrayOfItems:Array)
{
for (var i:int = 0; i < arrayOfItems.length; i++)
{
arrayOfItems[i].addEventListener(MouseEvent.CLICK,getItem);
arrayOfItems[i].buttonMode = true;
}
}
function getItem(e:Event)
{
var item:MovieClip = MovieClip(e.currentTarget);
itemsInInventory.push(item);
inventorySprite.addChild(item);
item.x = itemsInInventory.length - 1 * 40;
item.y = 0;
item.removeEventListener(MouseEvent.CLICK,getItem);
item.addEventListener(MouseEvent.CLICK,useItem);
}
function useItem(e:Event)
{
var item:MovieClip = MovieClip(e.currentTarget);
trace(("Use Item:" + item.name));
}
}
}
Currently i can only click and trace the output, I was wondering how i can drag the sprite and use it to another object...like a key to unlock a door. Big thanks, btw im new in as3 and im trying to learn from stack overflow.

Answer 1

item.addEventListener(MouseEvent.CLICK,useItem);
var drag:Boolean;
function useItem(e:Event)
{
var item:MovieClip = MovieClip(e.currentTarget);
trace(("Use Item:" + item.name));
if(drag == false)
{
item.startDrag();
drag = true;
}else{
item.stopDrag();
drag = false;
findAction(e);
}
}
function findAction(e)
{
// Check the position of the key relative to the door.
}
Haven't really checked it but it'd probably work if you did something similar.
