這篇文章主要為大家詳細(xì)介紹了Unity實(shí)現(xiàn)聊天室功能，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了Unity實(shí)現(xiàn)聊天室功能的具體代碼，供大家參考，具體內(nèi)容如下

簡(jiǎn)單聊天室功能，客戶端發(fā)送消息后，服務(wù)器接收到消息后分發(fā)到其它客戶端上并顯示聊天內(nèi)容

聊天室服務(wù)器

服務(wù)器需要有以下幾個(gè)步驟

1、確定Socket協(xié)議類型（采用TCP協(xié)議或者UDP協(xié)議）
2、綁定服務(wù)器的IP地址和端口號(hào)
3、設(shè)置最大監(jiān)聽數(shù)量
4、等到連接并處理消息

由于服務(wù)器屬于一對(duì)多的處理關(guān)系，因?yàn)槲覀冃枰镁€程來監(jiān)聽消息：

class Client
 {
  private Socket clientSocket;
  private Thread t;
  public bool Connected
  {
   get
   {
    return clientSocket.Connected;
   }
  }
  private byte[] data = new byte[1024];//數(shù)據(jù)容器
  public Client(Socket client)
  {
   clientSocket = client;
   //啟動(dòng)一個(gè)線程，處理客戶端的接受
   t = new Thread(ReceiveMsg);
   t.Start();
  }

  private void ReceiveMsg()
  {
   while (true)
   {
    //在接收數(shù)據(jù)之前，判斷Socket連接是否斷開
    if (!clientSocket.Connected)
    {
     clientSocket.Close();
     break;//跳出循環(huán)終止線程的執(zhí)行
    }
    int length=clientSocket.Receive(data);
    string msg = Encoding.UTF8.GetString(data, 0, length);
    //服務(wù)端接收數(shù)據(jù)后，要將數(shù)據(jù)分發(fā)到客戶端
    //廣播消息
    Program.BroadcastMsg(msg);
   }
  }

  public void SendMsg(string msg)
  {
   byte[] data = Encoding.UTF8.GetBytes(msg);
   clientSocket.Send(data);
  }

  
 }

服務(wù)器主要代碼：

class Program
 {
  static List<Client> clients = new List<Client>();
  //本機(jī)IP：192.168.100.172
  static void Main(string[] args)
  {
   Socket tcpServer = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
   tcpServer.Bind(new IPEndPoint(IPAddress.Parse("192.168.100.172"), 7788));
   tcpServer.Listen(5000);
   Console.WriteLine("Server Running.......");
   while (true)
   {
    var clientSocket = tcpServer.Accept();
    Console.WriteLine("建立連接");
    Client client = new Client(clientSocket);
    clients.Add(client);
   }
  }

  public static void BroadcastMsg(string msg)
  {
   var noConnecteds = new List<Client>();
   foreach (var client in clients)
   {
    if (client.Connected)
    {
     client.SendMsg(msg);
    }
    else
    {
     noConnecteds.Add(client);
    }
   }
   foreach (var del in noConnecteds)
   {
    clients.Remove(del);
   }
  }
}

Unity客戶端代碼

Unity客戶端代碼就十分簡(jiǎn)單，監(jiān)聽服務(wù)器的消息并顯示到界面上即可

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.Net;
using System.Net.Sockets;
using System.Text;
using UnityEngine.UI;
using System.Threading;
public class ChatManager : MonoBehaviour
{
 public string IP = "192.168.100.172";
 public int Port = 7788;
 private Socket client;
 private Thread t;
 public InputField input;
 public Button sendBtn;
 public Text item;

 public string name;

 private string msg=string.Empty;
 // Start is called before the first frame update
 void Start()
 {
  ConnectedToServer();
  sendBtn.onClick.AddListener(() => {
   SendMsg(input.text);
   input.text = string.Empty;
  });
 }

 // Update is called once per frame
 void Update()
 {
  //由于在Unity中不允許在線程中調(diào)用UnityAPI，因此需要的Update中刷新顯示
  if (!string.IsNullOrEmpty(msg))
  {
   item.text += "\n" + msg;
   msg = string.Empty;
  }
 }

 private void ConnectedToServer()
 {
  client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
  client.Connect(new IPEndPoint(IPAddress.Parse(IP), Port));
  //創(chuàng)建一個(gè)線程用來接收消息
  t = new Thread(ReceiveMsg);
  t.Start();
 }
 byte[] data = new byte[1024];
 public void ReceiveMsg()
 {
  while (true)
  {
   if (!client.Connected)
   {
    break;
   }
   int length = client.Receive(data);
   msg = Encoding.UTF8.GetString(data, 0, length);

  }
 }
 public void SendMsg(string msg)
 {
  byte[] data = Encoding.UTF8.GetBytes(name+":"+msg);
  client.Send(data);
 }

 public void OnDestroy()
 {
  client.Close();
 }
}

實(shí)際運(yùn)行效果（注意需要先啟動(dòng)服務(wù)器）：
