Problem with translating C# variable to JS.

Hello.

I am putting this code in Standard Assets folder:

using UnityEngine;
using System;
using System.Collections;
using System.IO;    

public class ResolutionChanger : MonoBehaviour
{
        public string fileName = "Settings.ini";
	public float timer; 	
  private int screenWidth;
    private int screenHeight;   
    private int fullscreen;    

    void Start()
    {      
        using (StreamReader fileStream = File.OpenText(Path.GetFullPath(fileName)))
        {          
            string fileLine = "";
            while ((fileLine = fileStream.ReadLine()) != null)
            {
                string option = fileLine.Substring(0, fileLine.IndexOf("="));
                switch (option)
                {
					case "gametime":
                        timer = Convert.ToInt32(fileLine.Substring(fileLine.IndexOf("=") + 1));
                        break;
                    case "screenwidth":
                        screenWidth = Convert.ToInt32(fileLine.Substring(fileLine.IndexOf("=") + 1));
                        break;

                    case "screenheight":
                        screenHeight = Convert.ToInt32(fileLine.Substring(fileLine.IndexOf("=") + 1));
                        break;

                    case "radius":
                        fullscreen = Convert.ToInt32(fileLine.Substring(fileLine.IndexOf("=") + 1));
                        break;					
					}

            }           
            fileStream.Close();
        }		
       		Screen.SetResolution(screenWidth, screenHeight, false);
	} 	

}

And its working. I have access from text file. But when i try to use the variable “timer” in other JS file, like this:

private var csScript : ResolutionChanger; 
   
function Awake()  
{  
   csScript = this.GetComponent("ResolutionChanger");
}

var guiScore : GUIText;    
var myTimer = csScript.timer; 

function Update (){    
		myTimer -= Time.deltaTime;    		
	if(myTimer < 0){
		Application.LoadLevel("GameOver");
		}    		
var count : int = myTimer;		
guiScore.text = " " + count;  
}

I have an error: NullReferenceException: Object reference not set to an instance of an object Timer..ctor () (at Assets/scripts/Timer.js:10)
Whats the problem?

you cant mix and match java and C# like that. Google accessing a javascript from a C# unity for more information.

csScript isn’t set to any thing.

Order of operations: First executed is code outside any function, then Awake, then Start, then Update.

You’re setting something = csScript.something outside a function, then you’re setting csScript = something in Awake.
