Update not being called

Hi all,
I can't seem to figure out what I have done wrong.

I made a generic Singleton Object like so:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class Singleton<T> : MonoBehaviour where T : Component
4. {
5.     private static T instance;
6.     public static T Instance
7.     {
8.         get
9.         {
10.             if (instance == null)
11.             {
12.                 instance = FindObjectOfType<T>();
13.                 if (instance == null)
14.                 {
15.                     GameObject obj = new GameObject();
16.                     obj.name = typeof(T).Name;
17.                     instance = obj.AddComponent<T>();
18.                 }
19.             }
20.             return instance;
21.         }
22.     }
23.  
24.     protected virtual void Awake()
25.     {
26.         if (instance == null)
27.         {
28.             instance = this as T;
29.         }
30.         else
31.         {
32.             Destroy(gameObject);
33.         }
34.     }
35. }
36.  

Afterward I created a GameManager class:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class GameManager : Singleton<GameManager>
4. {
5.     [SerializeField]
6.     private float gameTimer;
7.     public float GameTimer => gameTimer;
8.  
9.     protected override void Awake()
10.     {
11.         base.Awake();
12.         Debug.Log("Started Game manager");
13.     }
14.  
15.     private void Update()
16.     {
17.         gameTimer -= Time.deltaTime;
18.     }
19.  
20. }
21.  

My problem is that the update method on the GameManager is never being called.
and it is attached to a game object in the active scene

any ideas?

Thanks in advance

 

Is the object active? Is the script itself active?

 

Did you debug log the update function?

 

My problem was that another script was calling the instance of the singleton in it's awake before.
so it did the destory method and the object was destoryed.
Took me a while to figure out what happens
