Unity C#单例模式的实现

一、添加单例模板类

 

using UnityEngine;public class Singleton<T> : MonoBehaviour where T : MonoBehaviour {private static T _instance;private static object _lock = new object ();public static T Instance {get {if (applicationIsQuitting) {return null;}lock (_lock) {if (_instance == null) {_instance = (T)FindObjectOfType (typeof(T));if (FindObjectsOfType (typeof(T)).Length > 1) {return _instance;}if (_instance == null) {GameObject singleton = new GameObject ();_instance = singleton.AddComponent<T> ();singleton.name = "(singleton) " + typeof(T).ToString ();DontDestroyOnLoad (singleton);}}return _instance;}}}private static bool applicationIsQuitting = false;public void OnDestroy (){applicationIsQuitting = true;} }

 

二、定义自己的单例类

using UnityEngine; using System;public class GameManager : Singleton<GameManager> {public float score;void Awake () {this.Init();}private void Init() {// Init code } }

 

三、调用使用

GameManager.Instance.score = 99;
