本文介绍了一个基于Unity的网络编程案例，使用Photon Engine实现客户端和服务端的连接与交互。客户端通过UDP协议连接到本地服务器，并能发送自定义消息，接收来自服务端的操作响应。

继搭建好简单的服务端后，开始尝试进行客户端的连接，交互

客户端代码

public class PhotonEngineTest : MonoBehaviour, IPhotonPeerListener
{
    private static PhotonEngineTest Instance;
    private static PhotonPeer peer;



    void Awake()
    {
        if (Instance == null)
        {
            Instance = this;
            DontDestroyOnLoad(this.gameObject);
        }
        else if (Instance != this)
        {
            Destroy(this.gameObject);
            return;
        }
    }

    // Use this for initialization
    void Start()
    {
        if (peer==null)
        {
            Debug.Log(peer);
            peer = new PhotonPeer(this, ConnectionProtocol.Udp);
        }
       
        peer.Connect("127.0.0.1:5055", "GameServer");
        Debug.Log(peer);
    }

    // Update is called once per frame
    void Update()
    {
        peer.Service();
    }
    public static PhotonPeer Peer
    {
        get { return peer; }
    }

  

    public void DebugReturn(DebugLevel level, string message)
    {
    }
//接受服务端返回的消息
    public void OnOperationResponse(OperationResponse operationResponse)
    {
        switch (operationResponse.OperationCode)
        {
            case 1:
                Debug.Log("case 1 ,Server's Response");
                object intvalue;
                object strvalue;
                Dictionary<byte, object> date = operationResponse.Parameters;
                date.TryGetValue(1, out intvalue);
                date.TryGetValue(2, out strvalue);
                Debug.Log("the response data is "+intvalue+" and "+strvalue);

                break;
            case 2:
                Debug.Log("case 2 ,Server's Response");
                break;
        }
    }

    public void OnStatusChanged(StatusCode statusCode)
    {
        Debug.Log(statusCode);
    }

    public void OnEvent(EventData eventData)
    {
    }

    public void OnDestory()
    {
      
        if (peer != null & peer.PeerState == PeerStateValue.Connected)
        {
           
            peer.Disconnect();
           // peer.StopThread();

        }
    }
}

  class Test:MonoBehaviour
    {
        void Update()
        {
            if (Input.GetMouseButtonDown(0))
            {
                SendMessage();
            }
            
        }
//向服务端发起请求
        void SendMessage()
        {
            Dictionary<byte, object> data = new Dictionary<byte, Object>();
            data.Add(1, 5);
            data.Add(2,"chenyongchao");

            //通过建立的连接发送数据
            PhotonEngineTest.Peer.OpCustom(1,data, true);
        }

    }
