unity 简单消息机制

Msg:定义消息体

public class Msg
{
	private Dictionary<string, object> data = new Dictionary<string, object>();
	
	/// <summary>
	/// 得到数据
	/// </summary>
	/// <returns></returns>
	public object GetData(string key)
	{
		if (data.ContainsKey(key))
			return data[key];

		return null;
	}

	/// <summary>
	/// 设置数据
	/// </summary>
	/// <param name="key"></param>
	/// <param name="value"></param>
	/// <returns></returns>
	public Msg SetData(string key, object value)
	{
		if (data.ContainsKey(key))
		{
			Debug.LogError("重复添加消息Key！！");
		}
		else
		{
			data.Add(key, value);
			return this;
		}
		return null;
	}
}
           

MessageManager：消息管理类

public class MessageManager
{
	public delegate void MsgDelegate(Msg obj);
	private static Dictionary<string, MsgDelegate> m_Msg = new Dictionary<string, MsgDelegate>();

	/// <summary>
	/// 添加消息
	/// </summary>
	/// <param name="key">消息名称</param>
	/// <param name="action">消息体</param>
	public static void AddListener(string key, MsgDelegate action)
	{
		if (!m_Msg.ContainsKey(key))
		{
			m_Msg.Add(key, action);
		}
		else
		{
			m_Msg[key] += action;
		}
	}

	/// <summary>
	/// 移除消息
	/// </summary>
	/// <param name="key">消息名称</param>
	/// <param name="action">消息体</param>
	public static void RemoveListener(string key, MsgDelegate action)
	{
		if (m_Msg.ContainsKey(key))
		{
			if (!m_Msg.ContainsValue(action))
			{
				Debug.LogError("不存在当前传递消息体，请检查");
				return;
			}
			m_Msg[key] -= action;
		}
	}

	/// <summary>
	/// 移除所有消息
	/// </summary>
	public static void RemoveAllListener()
	{
		m_Msg.Clear();
	}

	/// <summary>
	/// 发送消息
	/// </summary>
	/// <param name="key"></param>
	public static void SendMsg(string key)
	{
		if (m_Msg.ContainsKey(key))
		{
			m_Msg[key]?.Invoke(null);
		}
	}

	public static void SendMsg(string key, Msg msg)
	{
		if (m_Msg.ContainsKey(key))
		{
			m_Msg[key]?.Invoke(msg);
		}
	}
}
           

测试：

public class Test : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
		if (Input.GetKeyDown(KeyCode.A))
			MessageManager.SendMsg("test",new Msg ().SetData("value",1).SetData("value1",2));
    }
}
           

public class Cube : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
		MessageManager.AddListener("test",TestFun);
    }

	private void TestFun(Msg obj)
	{
		var value = obj.GetData("value");
		var value1 = obj.GetData("value1");
		Debug.Log("value = "+ value+ ", value1 = " + value1);
	}

	private void OnDestroy()
	{
		MessageManager.RemoveListener("test", TestFun);
	}
}
