Unity简单的单例模式 

 1 using UnityEngine;
 2 using System.Collections;
 3 
 4 public class SingleMono<T> : MonoBehaviour where T : MonoBehaviour
 5 {
 6     private static T _instance;
 7     public static T Instance()
 8     {
 9         if (_instance == null)
10         {
11             _instance = (T)FindObjectOfType(typeof(T));
12             if (_instance == null)
13             {
14                 GameObject singleton = new GameObject();
15                 _instance = singleton.AddComponent<T>();
16                 singleton.name = "(singleton) " + typeof(T).ToString();
17                 DontDestroyOnLoad(singleton);
18             }
19         }
20         return _instance;
21     }
22 }

Tips:FindObjectOfType<Type type> 返回类型为type的活动的第一个对象
