Unity常用的设计模式

        总结学习的一些Unity常用的设计模式，还在不断学习补充中...

1. 单例模式

   ---

   using UnityEngine;
   
   public class MonoSingleton: MonoBehaviour
   {
       protected static MonoSingleton s_Instance;
       public static MonoSingleton Instance => s_Instance;
   
       private void Awake()
       {
           if (s_Instance != null)
           {
               Destroy(gameObject);
           }
           else
           {
               s_Instance = this;
           }
       }
   
       private void OnDestroy()
       {
           if (s_Instance == this)
           {
               s_Instance = null;
           }
       }
   }

   泛型单例模式

   ---

   using UnityEngine;
   
   public class MonoSingleton : MonoBehaviour where T : MonoSingleton
   {
       protected static T s_Instance;
   
       public static T Instance => s_Instance;
   
       public static bool IsInitiated => s_Instance != null;
   
       protected virtual void Awake()
       {
           if (s_Instance != null)
           {
               Destroy(gameObject);
           }
           else
           {
               s_Instance = (T) this;
           }
       }
   
       protected virtual void OnDestroy()
       {
           if (s_Instance == this)
           {
               s_Instance = null;
           }
       }
   }
