Unity开发中经常会用到单例，下面是对单例的封装

C#单例

• 无需挂载

    public class Singleton<T> where T : Singleton<T>, new(){public static T Instance { get; } = new T();protected Singleton(){}}

Unity单例

• 需要挂载对象
  • 子类如果使用Awake需要重写父类

public class MonoSingleton<T> : MonoBehaviour where T : MonoSingleton<T>{public static T Instance { get; private set; }protected virtual void Awake(){Instance = this as T;}}
