Calling other variables problem.

I'm currently working on a racing game where the player has a limited amount of time to reach the finish line before the car blows-up. I have a script that controles the timer and I'm trying to get the car to not take the input of the player after time expires. I'm having a problem with this so please help. Thanks in advance.

The Script

Code (csharp):

1.  
2. var skin:GUISkin;
3. var player:Transform; var on : boolean = true;
4. private var startTime;
5. private var restSeconds : int;
6. private var roundedRestSeconds : int;
7. private var displaySeconds : int;
8. private var displayMinutes : int;
9. var explosionPrefab : GameObject;
10. var explosionLife : float = 2;
11. var countDownSeconds : int;
12. var heartbeat : AudioClip;
13. function Awake() {
14.     startTime = Time.time;
15. }
16. function OnGUI () {
17.         if (skin != null) {
18.         GUI.skin = skin;
19.     }
20.     var guiTime = Time.time - startTime;
21.     restSeconds = countDownSeconds - (guiTime);
22.     if (restSeconds == 60) {
23.         print ("One Minute Left");  
24.     }
25.     if (restSeconds == 12) {
26.         audio.clip = heartbeat;
27.         audio.Play(44100);
28.     }
29.     if (restSeconds == 0) {
30.         print ("Time is Over");
31.         var expPos = transform.position;
32.         var exp: GameObject = Instantiate (explosionPrefab, expPos, Quaternion.identity);
33.         Destroy(exp, explosionLife);
34.         var other : CarControl = gameObject.GetComponent(CarControl);
35.         other.motorInput = 0;
36.         other.brakeInput = 1;
37.         //player.GetComponent(CarControl).enabled = false;
38.         //player.GetComponent(SoundController).enabled = false;
39.         player.GetComponent(CarSettings).enabled = false;
40.         player.GetComponent(CarVisuals).enabled = false;
41.         Time.timeScale = 1;
42.     }
43.     roundedRestSeconds = Mathf.CeilToInt(restSeconds);
44.     displaySeconds = roundedRestSeconds % 60;
45.     displayMinutes = roundedRestSeconds / 60;
46.     text = String.Format (" {0:00}:{1:00}", displayMinutes, displaySeconds);
47.     GUI.Box (new Rect (Screen.width-200, 0, 180, 40), text);
48.     }
49.  

 

you can disable the input script on the car by using GetComponent()

 

Thanks!
