Placing an object into an array then retriving it after it has been deleted.

Unity Engine

I try to move a weapon into my inventory array, then delete the object from the world thinking that a digital copy has been made. when i try to instantiate the object from the object stored in the array, i get the error: MissingReferenceException: The object of type ‘GameObject’ has been destroyed but you are still trying to access it.
Here’s my code:

//Weapon.js

//Activate get called by the player when it picks the weapon up
function Activate(sender:Transform){
	inv=sender.GetComponent(Inventory);
	useable=false;
	inv.weapons.Add(this.transform);
	Destroy(this.gameObject);


}

//PlayerBehaviour.js

//Equip get called when i try to create a new weapon at my hand

function Equip(){
var inv:Inventory;
var wep:Transform;
inv=GetComponent(Inventory);
	if(!gameObject.GetComponentInChildren(Weapon)){
		wep=Instantiate(inv.weapons[0],rightHand.position, Quaternion.identity);
		wep.transform.parent=rightHand;
		wep.GetComponent(Weapon).isEquipped=true;
		weapon=wep.transform;
	}else{
		Destroy(weapon.gameObject);
		weapon=null;
	}
}

Can anyone help me out with this? Thanks.

When you add a reference type to an array you don’t add a copy of the object, you just add a reference to the object. This means if you then destroy the object the reference in the array will be null. Why not try deactivating the game object instead using SetActive.
