Laser fire/stop/repeat script not working as intended

I am wanting a laser beam to fire for x amount of seconds, stop for x amount of seconds, then repeat. I have set it up so the laser activates after a fairly long delay, and while it then activates for the correct amount of time after the initial firing it keeps going on and off constantly instead of repeating my coroutine. I might have done something wrong but it looks right to me?

Code (csharp):

1.  
2. {
3.     public GameObject Laser;
4.     private bool Stage1;
5.  
6.    void Start ()
7.  
8.     {
9.         Stage1 = true;
10.         StartCoroutine(WaitTimer());
11.  
12.     }
13.    
14.    void Update ()
15.  
16.     {
17.        
18.            if(Stage1 == false)
19.         {
20.  
21.             Laser.active = true;
22.             StartCoroutine(WaitTimer2());
23.  
24.         }
25.    
26.     }
27.  
28.     private IEnumerator WaitTimer()
29.     {
30.  
31.         yield return new WaitForSeconds(115.0f);
32.  
33.         Stage1 = false;
34.  
35.  
36.     }
37.  
38.     private IEnumerator WaitTimer2()
39.  
40.     {
41.  
42.         yield return new WaitForSeconds(3.0f);
43.  
44.         Laser.active = true;
45.  
46.         yield return new WaitForSeconds(5.0f);
47.  
48.         Laser.active = false;
49.  
50.        
51.  
52.  
53.  
54.     }
55. }
56.  
57.  
58.  

 

Using coroutines for something like this is a recipe for confusion. Why not keep it simple, with something like this.

Code (CSharp):

1. class PeriodicActivator : MonoBehaviour {
2.     public GameObject objectToActivate;
3.     public float onTime = 1;
4.     public float offTime = 1;
5.    
6.     void Update() {
7.         float totalTime = onTime + offTime;
8.         float t = Time.time % totalTime;
9.         objectToActivate.active = (t < onTime);
10.     }
11. }

 

Thank you so much I was using a coroutine as I had done a similar sort of setup with a different script, although that one has additional stuff including a while loop which I guess is needed other it doesn't work properly. Yours is much simpler and works perfectly
