下面利用Unity和C#語(yǔ)言做一個(gè)簡(jiǎn)單的聊天室程序，主要用到的技術(shù)就是Socket通信連接，需要一個(gè)客戶(hù)端和一個(gè)服務(wù)器端，服務(wù)器端就使用C#語(yǔ)言的控制臺(tái)完成
?一、C#語(yǔ)言服務(wù)器端搭建
下面就開(kāi)始搭建C#語(yǔ)言服務(wù)器端
1：新建一個(gè)C#語(yǔ)言控制臺(tái)程序
2：命名項(xiàng)目為Server 右擊項(xiàng)目新建項(xiàng)
3：新建類(lèi)MessageData.cs ClientController.cs MessageData類(lèi)存放指定的消息協(xié)議，每一條消息都由創(chuàng)建消息對(duì)象，設(shè)置消息類(lèi)型和消息內(nèi)容組成，服務(wù)器端和客戶(hù)端都必須配置這個(gè)消息協(xié)議
ClientController腳本用來(lái)控制所有的客戶(hù)端程序
部分代碼如下
using System;
using System.Net.Sockets;
using System.Threading;
namespace Server
{
class ClientController
{
/// <summary>
/// 用戶(hù)鏈接的通道
/// </summary>
private Socket clientSocket;
//接收的線程
Thread receiveThread;
/// <summary>
/// 昵稱(chēng)
/// </summary>
public string nickName;
public ClientController(Socket socket)
{
clientSocket = socket;
//啟動(dòng)接收的方法
//開(kāi)始收的線程
receiveThread = new Thread(ReceiveFromClient);
//啟動(dòng)收的線程
receiveThread.Start();
}
/// <summary>
/// 客戶(hù)端連接 監(jiān)聽(tīng)消息
/// </summary>
void ReceiveFromClient()
{
while (true)
{
byte[] buffer = new byte[512];
int lenght = clientSocket.Receive(buffer, 0, buffer.Length, SocketFlags.None);
string json = System.Text.Encoding.UTF8.GetString(buffer, 0, lenght);
json.TrimEnd();
if (json.Length > 0)
{
Console.WriteLine("服務(wù)器接收內(nèi)容：{0}", json);
MessageData data = LitJson.JsonMapper.ToObject<MessageData>(json);
switch (data.msgType)
{
case MessageType.Login://登陸
nickName = data.msg;
//1、通知客戶(hù)端登陸成功
MessageData backData = new MessageData();
backData.msgType = MessageType.Login;
backData.msg = "";
SendToClient(backData);
//2、通知所有客戶(hù)端，XXX加入房間
MessageData chatData = new MessageData();
chatData.msgType = MessageType.Chat;
chatData.msg = nickName + " 進(jìn)入了房間";
SendMessageDataToAllClientWithOutSelf(chatData);
break;
case MessageType.Chat://聊天
MessageData chatMessageData = new MessageData();
chatMessageData.msgType = MessageType.Chat;
chatMessageData.msg = nickName + ":" + data.msg;
SendMessageDataToAllClientWithOutSelf(chatMessageData);
break;
case MessageType.LogOut://退出
//1、通知客戶(hù)端，退出
MessageData logOutData = new MessageData();
logOutData.msgType = MessageType.LogOut;
SendToClient(logOutData);
//2、通知所有客戶(hù)端，XXX退出了房間
MessageData logOutChatData = new MessageData();
logOutChatData.msgType = MessageType.Chat;
logOutChatData.msg = nickName + " 退出了房間";
SendMessageDataToAllClientWithOutSelf(logOutChatData);
break;
}
}
}
}
/// <summary>
/// 向除了自身客戶(hù)端的其他所有客戶(hù)端廣播消息
/// </summary>
/// <param name="data"></param>
void SendMessageDataToAllClientWithOutSelf(MessageData data)
{
for (int i = 0; i < Program.clientControllerList.Count; i++)
{
if (Program.clientControllerList[i] != this)
{
Program.clientControllerList[i].SendToClient(data);
}
}
}
/// <summary>
/// 發(fā)消息給客戶(hù)端
/// </summary>
/// <param name="data">需要發(fā)送的內(nèi)容</param>
void SendToClient(MessageData data)
{
//把對(duì)象轉(zhuǎn)換為json字符串
string msg = LitJson.JsonMapper.ToJson(data);
//把json字符串轉(zhuǎn)換byte數(shù)組
byte[] msgBytes = System.Text.Encoding.UTF8.GetBytes(msg);
//發(fā)送消息
int sendLength = clientSocket.Send(msgBytes);
Console.WriteLine("服務(wù)器發(fā)送信息成功，發(fā)送信息內(nèi)容：{0}，長(zhǎng)度{1}", msg, sendLength);
Thread.Sleep(50);
}
}
}
需要注意的是，這個(gè)腳本引用了一個(gè)LitJson程序包解析JSON數(shù)據(jù)，這個(gè)需要右擊程序，選擇管理NuGet程序包選項(xiàng)，在彈出的窗口中搜索LitJson然后安裝即可
?
雙擊打開(kāi)Program.cs腳本，這個(gè)腳本是C#語(yǔ)言控制臺(tái)程序的主腳本，腳本中的一個(gè)Main函數(shù)是程序的入口函數(shù) 代碼如下
using System;
using System.Collections.Generic;
using System.Net;
using System.Net.Sockets;
namespace Server
{
class Program
{
/// <summary>
/// 客戶(hù)端管理列表
/// </summary>
public static List<ClientController> clientControllerList = new List<ClientController>();
static void Main(string[] args)
{
//定義socket
Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
//綁定IP和端口號(hào)
IPEndPoint ipendPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8080);
Console.WriteLine("開(kāi)始綁定端口號(hào)....");
//將ip地址和端口號(hào)綁定
serverSocket.Bind(ipendPoint);
Console.WriteLine("綁定端口號(hào)成功，開(kāi)啟服務(wù)器....");
//開(kāi)啟服務(wù)器
serverSocket.Listen(100);
Console.WriteLine("啟動(dòng)服務(wù)器{0}成功!", serverSocket.LocalEndPoint.ToString());
while (true)
{
Console.WriteLine("等待連接.....");
Socket clinetSocket = serverSocket.Accept();
Console.WriteLine("客戶(hù)端{(lán)0}成功連接", clinetSocket.RemoteEndPoint.ToString());
ClientController controller = new ClientController(clinetSocket);
//添加到列表中
clientControllerList.Add(controller);
Console.WriteLine("當(dāng)前有{0}個(gè)用戶(hù)", clientControllerList.Count);
}
}
}
}
服務(wù)器端目錄結(jié)構(gòu)如下
運(yùn)行服務(wù)器端 啟動(dòng)正常會(huì)彈出一個(gè)窗口
?
?二、Unity客戶(hù)端搭建
Unity客戶(hù)端搭建主要分為以下三個(gè)方面
1：搭建UI界面
2：制定消息協(xié)議
3：編寫(xiě)客戶(hù)端
首先搭建UI界面 UI界面分為三部分，分別是初始界面，登錄界面和聊天界面?
搭建步驟省略 需要可點(diǎn)贊關(guān)注收藏后評(píng)論區(qū)留言私信 效果如下
在Unity中新建一個(gè)Plugins文件夾 里面存放代碼文件和依賴(lài) 目錄如下
?
整體運(yùn)行效果如下?
運(yùn)行Unity客戶(hù)端 出現(xiàn)兩個(gè)聊天框 可以進(jìn)行實(shí)時(shí)的聊天互動(dòng)?
C#控制臺(tái)服務(wù)器端則會(huì)記錄聊天的信息以及用戶(hù)信息等等?
?
