當遊戲內需要多個Manager時，可以使用泛型單例來簡化我們的程式碼。

 1 using System.Collections;
 2 using System.Collections.Generic;
 3 using UnityEngine;
 4 
 5 //泛型單例
 6 public class Singleton<T> : MonoBehaviour where T:Singleton<T>
 7 {
 8     private static T instance;
 9 
10     public static T Instance
11     {
 
12         get { return instance; }
13     }
14 
15     protected virtual void Awake()
16     {
17         if(instance!= null)
18             Destroy(gameObject);
19         else
20             instance = (T)this;
21     }
22 
23     //判斷是否已經生成
24     public static bool IsInitialized
25     {
26         get
 
 { return instance != null; }
27     }
28 
29     //銷燬時置空
30     protected virtual void OnDestory()
31     {
32         if(instance == this)
33         {
34             instance = null;
35         }
36     }
37 }

繼承該模板類，即可實現單例模式

 1 using System.Collections;
 2 using System.Collections.Generic;
 3 using
 
 UnityEngine;
 4 
 5 public class GameManager : Singleton<GameManager>
 6 {
 7 
 8     protected override void Awake()
 9     {
10         base.Awake();
11         //DontDestroyOnLoad();
12     }
13 
14 }
