Time Not Unpausing

I have it set where in the gameDictionaries script it is calling stoptimer from timeScript in the makeProduct method. Then in the stopProduct method, I have it where it calls starttimer from the timeScript.

gameDictionaries:

Code (CSharp):

1.  
2. public void makeProduct(string message)
3.  
4.     {
5.  
6.         makeButton.gameObject.SetActive (true);
7.  
8.         makePanel.SetActive (true);
9.  
10.         make2button.gameObject.SetActive(true);
11.  
12.         totalDev.gameObject.SetActive(true);
13.  
14.         totalDev.GetComponent<Text>().text = "Total Development Cost: $" + totalMake.ToString();
15.  
16.         GetComponent<timeScript>().StopTimer()
17.  
18.     }
19.  

Code (CSharp):

1.  
2. public void stopProduct()
3.  
4.     {
5.  
6.         print (gameName);
7.  
8.         if (pickedsystem == "Develop for:")
9.  
10.         {
11.  
12.  
13.         }
14.  
15.         else
16.         {
17.             makeButton.gameObject.SetActive(false);
18.  
19.             makePanel.SetActive(false);
20.  
21.         }
22.  
23.         GetComponent<timeScript>().StartTimer();
24.  
25.     }
26.  
27. }
28.  

timeScript:

Code (CSharp):

1. public void StartTimer()
2.     {
3.  
4.         InvokeRepeating("TimerFunction", 0, 1);
5.  
6.     }
7.  
8.     public void StopTimer()
9.     {
10.  
11.         CancelInvoke("TimerFunction");
12.  
13.         Time.timeScale = 0f;
14.  
15.     }
16.  

Code (CSharp):

1. void Start()
2.     {
3.         InvokeRepeating("Timer", 0, 1);
4.     }
5.  

How do I get time to unfreeze?

 

I don't think invoke will work if timescale is 0. It cannot calculate the delay if time is stopped

 

Use a Coroutine, wait the amount of time using unscaled time:

Code (csharp):

1.  
2. IEnumerator WaitForRealSeconds(float dur)
3. {
4.     float start = Time.unscaledTime;
5.     while(Time.unscaledTime - start < dur)
6.         yield return null;
7. }
8.  

 

Is this for time freezing or unfreezing?

Code (CSharp):

1.  StartCoroutine(WaitForRealSeconds(time));

Is this a valid way of using this Coroutine?
