Unity实现局域网聊天室功能 Unity实现局域网聊天室功能

基于Unity实现一个简单的局域网聊天室，供大家参考，具体内容如下
学习Unity有一点时间了，之前学的都是做客户端的一些内容，现在开始学习联网。我的这个是在观看了 Siki 的教学内容来做的，也有自己的一点点小小的改动在里面。纯粹用于练手了。
【Unity实现局域网聊天室功能】因为本人也是小白一枚，所以，有错误的地方或者更好的实现方法，也希望有大神能帮忙指正，多谢!
整体过程分为两部分：构建服务端、构建客户端。
服务端：大概思路：
1. 声明Socket连接以及绑定IP和端口，这里面使用

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Net.Sockets; using System.Net; namespace ServerApplication{class Program{public static string IP; public static int Port; static List clientList = new List(); static Socket serverSocket; static void Main(string[] args){//绑定IP和端口BindIPAndPort(); //while (true){Socket clientSocket = serverSocket.Accept(); Client client = new Client(clientSocket); clientList.Add(client); Console.WriteLine("一台主机进入连接"); }}/// /// 广播数据/// public static void BroadcostMSG(string s){List NotConnectedList = new List(); foreach (var item in clientList){if(item.IsConnected){item.SendMSG(s); }else{NotConnectedList.Add(item); }}foreach (var item in NotConnectedList){clientList.Remove(item); }}/// /// 绑定IP和端口/// public static void BindIPAndPort(){//创建一个serverSocketserverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); //声明IP和端口Console.WriteLine("输入IP地址："); IP = Console.ReadLine(); string ipStr = IP; Console.WriteLine("请输入端口："); Port = int.Parse(Console.ReadLine()); int port = Port; IPAddress serverIp = IPAddress.Parse(ipStr); EndPoint serverPoint = new IPEndPoint(serverIp, port); //socket和ip进行绑定serverSocket.Bind(serverPoint); //监听最大数为100serverSocket.Listen(100); }}}

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Net.Sockets; using System.Threading; namespace ServerApplication{class Client{public Socket clientSocket; //声明一个线程用于接收信息Thread t; //接收信息所用容器byte[] data = https://www.it610.com/article/new byte[1024]; //构造函数public Client(Socket s){clientSocket = s; t = new Thread(ReceiveMSG); t.Start(); }/// /// 接收数据/// void ReceiveMSG(){while(true){if (clientSocket.Poll(10,SelectMode.SelectRead)){break; }data = new byte[1024]; int length = clientSocket.Receive(data); string message = Encoding.UTF8.GetString(data, 0, length); Program.BroadcostMSG(message); Console.WriteLine("收到消息：" + message); }}/// /// 发送数据/// /// public void SendMSG(string message){byte[] data = https://www.it610.com/article/Encoding.UTF8.GetBytes(message); clientSocket.Send(data); }//判断此Client对象是否在连接状态public bool IsConnected{get { return clientSocket.Connected; }}}}

客户端： a.UI界面
UI界面是使用UGUI实现的
登录用户可以自己取名进行登录（发言时用于显示），使用时需要输入服务端的IP地址和端口号

下面是聊天室的页面，在输入框内输入要发送的消息，点击Send，将信息发送出去

这是服务端的信息

b.关于客户端的脚本
（1）这是ClientManager，负责与服务端进行连接，通信

using System.Collections; using System.Collections.Generic; using UnityEngine; using System.Net.Sockets; using System.Net; using System.Text; using UnityEngine.UI; using System.Threading; public class ClientManager : MonoBehaviour{//ip:192.168.1.7public string ipAddressstr; public int port; public Text ipTextToShow; //Socketprivate Socket ClientServer; //文本输入框public InputField inputTxt; public string inputMSGStr; //接收Thread t; public Text receiveTextCom; public string message; // Use this for initializationvoid Start(){ipTextToShow.text = ipAddressstr; // ConnectedToServer(); }// Update is called once per framevoid Update(){if (message != null && message != ""){receiveTextCom.text = receiveTextCom.text + "\n" + message; message = ""; }}/// /// 连接服务器/// public void ConnectedToServer(){ClientServer = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); //声明IP地址和端口IPAddress ServerAddress = IPAddress.Parse(ipAddressstr); EndPoint ServerPoint = new IPEndPoint(ServerAddress, port); ipAddressstr = IpInfo.ipStr; port = IpInfo.portStr; //开始连接ClientServer.Connect(ServerPoint); t = new Thread(ReceiveMSG); t.Start(); }/// /// 接收消息/// /// “string”void ReceiveMSG(){while (true){if (ClientServer.Connected == false){break; }byte[] data = https://www.it610.com/article/new byte[1024]; int length = ClientServer.Receive(data); message = Encoding.UTF8.GetString(data, 0, length); //Debug.Log("有消息进来"); }}/// /// 发送string类型数据/// /// public void SendMSG(){Debug.Log("button Clicked"); //message = "我：" + inputTxt.text; inputMSGStr = inputTxt.text; byte[] data = https://www.it610.com/article/Encoding.UTF8.GetBytes(IpInfo.name+":"+inputMSGStr); ClientServer.Send(data); }private void OnDestroy(){ClientServer.Shutdown(SocketShutdown.Both); ClientServer.Close(); }private void OnApplicationQuit(){OnDestroy(); }}

（2）SceneManager，用于场景切换，这里只是利用GameObject进行SetActive（）来实现，并不是创建了单独的Scene进行管理。

using System.Collections; using System.Collections.Generic; using UnityEngine; public class SceneManager : MonoBehaviour {public GameObject loginPanel; public GameObject communicatingPanel; // Use this for initializationpublic void OnSwitch(){loginPanel.SetActive(false); communicatingPanel.SetActive(true); }}

（3）LogInPanel和IPInfo,一个挂载在登录界面上，一个是数据模型，用于存储数据。

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; public class LogInPanel : MonoBehaviour {public Text nameInputTxt; public Text ipInputTxt; public Text portInputTxt; //private string name; //private string ipStr; //private string portStr; public void OnLogInClick(){IpInfo.name = nameInputTxt.text; IpInfo.ipStr = ipInputTxt.text; IpInfo.portStr = int.Parse(portInputTxt.text); }}
