unity静态管理类

<转载>
unity类似全局类的静态实例一样的单例管理类
 1 public class Singleton<T>:MonoBehaviour
 2         where T:component
 3 {
 4     private static T Instance;
 5     public static T Instance
 6     {
 7        get
 8       {
 9         if(Instance == null)
10         {
11           Instance = FindObjectType(typeof(T)) as T;
12           if(Instance == null)
13           {
14              GameObject obj = new GameObject();
15              DontDestroyOnload(obj);
16              obj.hideFlags = HideFlags.HideInHierarchy;
17              Instance = obj.getcomponent<>();
18           }
19         }
20         return Instance;
21       }
22     
23      }
24 }  
调用方法：
Singleton<MonoBehaviour>.Instance.StartCoroutine(routine);
