事件中心（可用于不同模块间的通信，用于解耦）

单例模式

using UnityEngine;
using System.Collections;

namespace SingleTonBase
{
public class SingleTonBase<T> where T : new()
{

private static T _instance;
public static T GetInstance()
{
if (_instance == null)
_instance = new T();
return _instance;
}

}
public class SingleTonBehaviorBase<T> : MonoBehaviour where T : MonoBehaviour
{
private static T _instance;
public static T GetInstance()
{
_instance = GameObject.FindObjectOfType<T>();
if (_instance == null)
{
GameObject goObj = new GameObject(typeof(T).ToString());
_instance = goObj.AddComponent<T>();
}
return _instance;
}
}
}

消息中心 用于注册消息

using UnityEngine;
using System.Collections;

namespace Message
{
public class MessageConst
{
public static readonly string MESSAGE_TEST = "TEST";

}
}

事件中心，用于注册分发事件，传递消息

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using SingleTonBase;

public class NotificationCentre : SingleTonBehaviorBase<NotificationCentre>
{

public delegate void MessageDelegate(params object[] obj);
private Dictionary<string, MessageDelegate> _messageCache = new Dictionary<string, MessageDelegate>();

/// <summary>
/// 订阅消息
/// </summary>
/// <param name="messageKey">消息的关键字</param>
/// <param name="md">消息的委托函数</param>
public void RegisterMessage(string messageKey,MessageDelegate md)
{
if (_messageCache.ContainsKey(messageKey))
{
Debug.LogError("Don`t register again!!!");
return;
}
_messageCache.Add(messageKey,md);
}
/// <summary>
/// 发送消息
/// </summary>
/// <param name="messageKey">消息关键字</param>
public void SendMessage(string messageKey)
{
SendMessage(messageKey,null);
}
/// <summary>
/// 发送消息
/// </summary>
/// <param name="messageKey">消息关键字</param>
/// <param name="messageContent">消息内容</param>
public void SendMessage(string messageKey, params object[] messageContent)
{
if (!_messageCache.ContainsKey(messageKey))
{
Debug.LogError("The " + messageKey + "not be registered");
return;
}
_messageCache[messageKey](messageContent);
}

public void RemoveMessage(string messageKey)
{
if (_messageCache.ContainsKey(messageKey))
_messageCache.Remove(messageKey);
}

//public void RemoveMessage(MessageDelegate md)
//{
// if (_messageCache.ContainsValue(md))
// // _messageCache.Remove();
//}
}

测试脚本

using UnityEngine;
using System.Collections;
using Message;
public class TestNotification : MonoBehaviour {

void Awake()
{
//订阅
NotificationCentre.GetInstance().RegisterMessage(MessageConst.MESSAGE_TEST, AcceptMessage);
}

void AcceptMessage(params object[] message)
{
Debug.Log(message[0]);
Debug.Log(message[1]);
}

void Start () {
NotificationCentre.GetInstance().SendMessage(MessageConst.MESSAGE_TEST,"Hello Message",this.gameObject);
}
void OnDestroy()
{
NotificationCentre.GetInstance().RemoveMessage(MessageConst.MESSAGE_TEST);
}

}
