How to add money?

Question

I have chests that open and give me money. When I open the first chest it gives me 500, but when I open a second chest it is adding the new amount to the original money amount of 0 and I am still left with 500. here is my code please help:

var money : int; var GUIMoney : GUIText; var target : Transform; var moneyAmount : int;

function OnTriggerEnter( other : Collider ) { if (other.tag == "Player") { money+= moneyAmount; GUIMoney.text = money.ToString(); Destroy(other.gameObject); } }

function Update(){ MoneyPU(); }

function MoneyPU(){ distance = Vector3.Distance(target.transform.position, transform.position);

     if(distance &lt; 2){
         if(Input.GetButtonDown("Activate")){
             yield WaitForSeconds(1);
             money+= moneyAmount; 
             GUIMoney.text = money.ToString();
             Destroy (this);

         }
     }

}

You need to store "money" and "moneyAmount" in different scripts (or instances) because at the moment each script is updating its own money amount which will always be 0. Store the player's money on the player object or a game controller object separate from the pickups.

e.g.

money script:

var moneyAmount : int = 500;

function OnTriggerStay( other : Collider ) { // check for player tag and active button if (other.tag == "Player" && Input.GetButtonDown("Activate")) { // send a message to the player object other.gameObject.SendMessage("AddMoney",moneyAmount); // removed the money Destroy(gameObject); } }

player script:

var money : int = 0; var GUImoney : GUIText;

function AddMoney(amount :int){ money += amount; GUIMoney.text = money.ToString(); }
