I recently got some help with this script but now it is playing up again so i am back for more help
It is giving me the error
NullReferenceException: Object reference not set to an instance of an object
Coin.OnTriggerEnter2D (UnityEngine.Collider2D other) (at Assets/Coin.js:11)
which means it is not being called or something like that but i dont know why here is the two scripts
Coin script:
#pragma strict
var Money : MenuShopSystem ;
functi
on Start () {
}
function OnTriggerEnter2D (other: Collider2D)
{
Debug.Log ("Touch");
Money.Money += 100;
Destroy(gameObject.Find("Coin"));
}
Shop script (what the coin script is calling from)
#pragma strict
//add this script to any gameObject you want//
//paste this to add more items to youre shop:
// if(GUI.Button(Rect(Screen.width/2,Screen.height/2,150,150), Item)){
// if(Money >= 200){
// Money -= 200;
// }else{
// Money -=0;
// }
// }
// GUI.Button(Rect(Screen.width/2+150,Screen.height/2,150,150), "Buy: 200");
//variables----------------------------------------
var ShowShop = false;
var CoinTexture : Texture;
public var Money :int=0;
var skin : GUISkin;
var AddButton = false;
//Items:
//to add more items just copy this variable and add the item name;
var Item : Texture;
var Item2 :Texture;
var Item3 :Texture;

function Start () {
Money = PlayerPrefs.GetInt("Money", 0);
}
function Update () {
PlayerPrefs.SetInt ("Money", Money);
if(Money <= 0){
Money = 0;
}
}
function OnGUI(){
GUI.skin = skin;
if(ShowShop ==true){
