先打开Unity3d，在Assert下创建一个Plugins文件夹，将PhotonServer SDK文件夹下lib下的Photon3Unity3D.dll拖到Plugins文件夹下

服务器端和客户端之间的关系图：

创建一个空物体，名字为PhotonEngine，创建一个脚本，名字为PhotonEngine：

using ExitGames.Client.Photon;using System.Collections;using System.Collections.Generic;using UnityEngine;public class PhotonEngine : MonoBehaviour,IPhotonPeerListener {    private static PhotonEngine Instance;    private static PhotonPeer peer;    public static PhotonPeer Peer    {        get { return peer; }    }        void Awake()    {        if(Instance==null)   //单例模式的处理，只有一个Instance        {            Instance = this;            DontDestroyOnLoad(this.gameObject);     //不销毁这个物体                    }        else if(Instance!=this)        {            Destroy(this.gameObject);return;       //删除多余的PhotonEngine        }    }// Use this for initializationvoid Start ()    {        //通过Listender接收服务器端的响应        peer = new PhotonPeer(this, ConnectionProtocol.Udp);        peer.Connect("127.0.0.1:5055", "MyGame1");      //连接服务器端}// Update is called once per framevoid Update ()    {        //if(peer.PeerState==PeerStateValue.Connected)  //判断peer已经连接        //{            peer.Service();  //什么状态下都要执行        //}       }    void OnDestroy()    {        if(peer!=null && peer.PeerState==PeerStateValue.Connecting)        {            peer.Disconnect();            //断开连接        }    }    public void DebugReturn(DebugLevel level, string message)    {            }    //处理服务器端直接发送过来的信息    public void OnEvent(EventData eventData)    {        switch(eventData.Code)        {            case 1:                Dictionary<byte,object> data = eventData.Parameters;                object intValue;                data.TryGetValue(1, out intValue);                object stringValue;                data.TryGetValue(2, out stringValue);                Debug.Log("接收服务器直接发送来的信息:"+intValue.ToString()+stringValue.ToString());                break;            case 2:                break;            default:                break;        }    }    //接收服务器发来的响应    public void OnOperationResponse(OperationResponse operationResponse)    {        switch(operationResponse.OperationCode)        {            case 1:                Debug.Log("接收一个来自服务器的响应");                Dictionary<byte,object> data = operationResponse.Parameters;                object intValue;                data.TryGetValue(1, out intValue);                object stringValue;                data.TryGetValue(2, out stringValue);                Debug.Log("接收来自服务器端的响应数据：" + intValue.ToString() + stringValue.ToString());                break;            case 2:                break;            default:                break;        }    }    public void OnStatusChanged(StatusCode statusCode)    {        Debug.Log(statusCode);    }}

创建一个Test脚本，放在PhotonEngine物件上：

public class test : MonoBehaviour {// Update is called once per framevoid Update ()    {if(Input.GetMouseButtonDown(0))        {            SendRequest();        }}    void SendRequest()    {        Dictionary<byte, object> data = new Dictionary<byte, object>();        int intValue=100;               //向服务器端发送数据        data.Add(1, intValue);        string stringValue = "hfasfadh滑石粉哈";        data.Add(2, stringValue);        PhotonEngine.Peer.OpCustom(1, data, true);     //向服务器端发送信息    }}

在服务器端的ClientPeer类中实现通信：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using Photon.SocketServer;using PhotonHostRuntimeInterfaces;namespace MyGameServer{    public class ClientPeer : Photon.SocketServer.ClientPeer    {        public ClientPeer(InitRequest initRequest):base(initRequest)        {        }        //处理客户端断开连接的后续工作        protected override void OnDisconnect(DisconnectReason reasonCode, string reasonDetail)        {                    }        //处理客户端的请求        protected override void OnOperationRequest(OperationRequest operationRequest, SendParameters sendParameters)        {            switch(operationRequest.OperationCode) //通过opCode区分            {                case 1:                    MyGameServer.log.Info("接收了一个客户端的请求");                    Dictionary<byte,object> data= operationRequest.Parameters;                    object intValue;                    data.TryGetValue(1, out intValue);    //得到客户端发送的数据                    object stringValue;                    data.TryGetValue(2, out stringValue);                    MyGameServer.log.Info("接收来自客户端的数据：" + intValue.ToString() + stringValue.ToString());                    OperationResponse opResponse = new OperationResponse(1);                    Dictionary<byte, object> data2 = new Dictionary<byte, object>();                    int intValue2 = 100;                    string stringValue2 = "asfaasdf发了疯has";                    data2.Add(1, intValue2);                    data2.Add(2, stringValue2);                    opResponse.SetParameters(data2);           //向客户端回应数据                    SendOperationResponse(opResponse, sendParameters);   //向客户端发出响应                    EventData ed = new EventData(1);                    Dictionary<byte, object> data3 = new Dictionary<byte, object>();                    int intValue3 = 200;                    data3.Add(1, intValue3);                    string stringValue3 = "fdasf飞杰";                    data3.Add(2, stringValue3);                    ed.SetParameters(data3);                    SendEvent(ed, new SendParameters());      //直接向客户端发送信息                                        break;                case 2:                    break;                default:                    break;            }        }    }}
