1.0 需要掛載遊戲物件的單例類

 public abstract class SingletonBaseMono<T> : MonoBehaviour where T : SingletonBaseMono<T>
{
    protected static T _Instance = null;
    public static T Instance
    {
        get
        {
            if (null == _Instance)
            {
                //尋找是否存在當前單例類物件
 

                GameObject go = GameObject.Find(typeof(T).Name);
                //不存在的話
                if (go == null)
                {
                    //new一個並新增一個單例指令碼
                    go = new GameObject();
                    _Instance = go.AddComponent<T>();
                }
                else
 

                {
                    if (go.GetComponent<T>() == null)
                    {
                        go.AddComponent<T>();
                    }
                    _Instance = go.GetComponent<T>();
                }
                //在切換場景的時候不要釋放這個物件
                DontDestroyOnLoad(go);
            }
            return
 
 _Instance;
        }
    }
}               

2.0 資料類單例

public class SingletonBase<T> where T : class ,new()
{
    private static T _instance=null;

    public static T Instance
    {
        get
        {
            if (_instance == null)
            {
                _instance = new T();
            }
            return _instance;
        }
    }

    //構造的同時呼叫初始化函式
        protected SingletonBase()
        {
            if (null != _instance)
            Init();
        }

    public virtual void Init()
    {

    }
}
