how to reset my timer while switching from one scene to other scene.
This is my timer script in scene 0:

Code (csharp):

1.  
2. #pragma strict
3.  
4.     var startTime:float;
5.      
6.     var timeR:float;
7.      
8.   function Awake()
9.      
10.     {
11.  
12.     startTime=10.0;
13.      
14.     guiText.material.color=Color.blue;
15.      
16.     InvokeRepeating ("Countdown",0.0f,1.0f);
17.      
18.     }
19.      
20.      
21.      
22.     function Countdown(){
23.      
24.     timeR =startTime - Time.time;
25.      
26.     ShowTime();
27.      
28.     if(timeR<0)
29.      
30.     {
31.      
32.    
33.  
34. CancelInvoke();
35.  
36.  
37.  
38. TimeIsUp();
39.      
40.      
41.     Debug.Log("TIME IS UP=" +timeR);
42.      
43.     }}
44.      
45.     function ShowTime()
46.      
47.     {
48.      
49.     var minutes:int;
50.      
51.     var seconds:int;
52.    
53.    
54.      
55.     var timeString:String;
56.      
57.     minutes=timeR / 60;
58.    
59.     seconds=timeR % 60;
60.    
61.    
62.  
63.    
64.    timeString=minutes.ToString()+":"+seconds.ToString ("00");
65.    // timeString=minutes.ToString()+":"+seconds.ToString("00");
66.      
67.     guiText.text=timeString;
68.      
69.     }
70.      
71.     function TimeIsUp()
72.      
73.     {
74.      
75.      
76.      
77.    guiText.text="Game Over";
78.  
79.     Application.LoadLevel(1);
80.      
81.     }
82.  
83.  
84.  
85.  
86.  

And this is my button script in scene1:

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5.  
6. public class trys : MonoBehaviour {
7.  
8.      
9.     void Awake ()
10.     {
11.    
12.        
13.        
14.     }
15.    
16.      
17.     void Update ()
18.     {
19.    
20.     }
21.     void OnGUI()
22.     {
23.      
24.     if(GUILayout.Button("TRY AGAIN"))
25.            
26.             {
27.                
28.             Application.LoadLevel(0);
29.            
30.             }
31.            
32.         }
33.        
34.     }
35.    
36.    
37.  
38.  
39.  
40.  
41.
