Class as Points system Help!

Unity Engine
1

'm New to use “Class”.
I’m trying to create a system which the objective is a points system for the NPC cars.
The script works but I just can not use as it should be in the GUI and PlayerPrefs class.
Whose purpose is to display the score of each car, the problem is I can not use the gui and correctly display the score of their car, and problem use PlayerPref to save and load the respective score of the car, a simple menu’s display NPC points obtained.
Not sure why, but it will be because of the class?

The scripts in Attach:

Attach “MainObject to gamobject player controller o car etc…”

1438825–77112–$MainClass.js (238 Bytes)
1438825–77113–$MainObject.js (841 Bytes)

It is easier if you paste the code here, instead of attaching files.

MainClass:

#pragma strict

// Class to call.


class MainJob {


    // The currect car name to display.
    var CarName : String = "Default";    
    // The currect car ID.
    var CarID : int = 1;    
    // The currect car Points to get.
    var CarPoints : int = 0;    
}

MainObject:

#pragma strict

// Call the class  script.
var mainClass : MainJob;
// The currect car ID to modify in the Inspector.
var curID : int = 1;
// The currect car Points to modify in the Inspector.
var currectPoints : int = 0;
// The currect car name to modify in the Inspector.
var Thename : String = "Barmy Army-";


function PointsSystem()
{
    // The currect class variable (CarName).
    mainClass.CarName = Thename;
    // The currect class variable (CarID).
    mainClass.CarID = curID;    
    // The currect class variable (CarPoints).
    mainClass.CarPoints = currectPoints;    
    // Set currect points.
    currectPoints ++;
    // Debug Test only.        
    Debug.Log(mainClass.CarName +"curPoints! > " + mainClass.CarPoints + "carID " + mainClass.CarID);    
}


function OnCollisionEnter(col : Collision) {


    if (col.gameObject.tag == "COM")
    {            
        PointsSystem();
    }
}
