using UnityEngine; using System.Collections; abstract public class Singleton<T> : MonoBehaviour where T : Singleton<T> { private static T m_instance = null; public static T instance { get { if (m_instance == null) { Object go = GameObject.FindObjectOfType(typeof(T)); if (go != null) { m_instance = go as T; } if (m_instance == null) { GameObject obj = new GameObject("_" + typeof(T).FullName); m_instance = obj.AddComponent(typeof(T)) as T; } } return m_instance; } } protected virtual void Awake() { if (m_instance == null) { m_instance = this as T; } else if (m_instance != this) { Debug.LogError(" multi-singleton in scene!!! ", gameObject); gameObject.SetActive(false); } } } |
使用方式： （调用DemoSingleton.instance）
