Unity局域网聊天室 Unity实现局域网聊天室功能
高小耸 人气:0想了解Unity实现局域网聊天室功能的相关内容吗,高小耸在本文为您仔细讲解Unity局域网聊天室的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:Unity局域网聊天室,Unity局域网聊天,Unity聊天室,下面大家一起来学习吧。
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。
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<Client> clientList = new List<Client>(); 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"); } } /// <summary> /// 广播数据 /// </summary> public static void BroadcostMSG(string s) { List<Client> NotConnectedList = new List<Client>(); foreach (var item in clientList) { if(item.IsConnected) { item.SendMSG(s); } else { NotConnectedList.Add(item); } } foreach (var item in NotConnectedList) { clientList.Remove(item); } } /// <summary> /// 绑定IP和端口 /// </summary> public static void BindIPAndPort() { //创建一个serverSocket serverSocket = 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100 serverSocket.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 = new byte[1024]; //构造函数 public Client(Socket s) { clientSocket = s; t = new Thread(ReceiveMSG); t.Start(); } /// <summary> /// 接收数据 /// </summary> 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); } } /// <summary> /// 发送数据 /// </summary> /// <param name="s"></param> public void SendMSG(string message) { byte[] data = 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:192.168.1.7 public string ipAddressstr; public int port; public Text ipTextToShow; //Socket private 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 initialization void Start() { ipTextToShow.text = ipAddressstr; // ConnectedToServer(); } // Update is called once per frame void Update() { if (message != null && message != "") { receiveTextCom.text = receiveTextCom.text + "\n" + message; message = ""; } } /// <summary> /// 连接服务器 /// </summary> 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(); } /// <summary> /// 接收消息 /// </summary> /// <returns>“string”</returns> void ReceiveMSG() { while (true) { if (ClientServer.Connected == false) { break; } byte[] data = new byte[1024]; int length = ClientServer.Receive(data); message = Encoding.UTF8.GetString(data, 0, length); //Debug.Log("有消息进来"); } } /// <summary> /// 发送string类型数据 /// </summary> /// <param name="input"></param> public void SendMSG() { Debug.Log("button Clicked"); //message = "我:" + inputTxt.text; inputMSGStr = inputTxt.text; byte[] data = 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 initialization public 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); } }
public static class IpInfo { public static string name; public static string ipStr; public static int portStr; }
总结:第一次写学习博,还有很多地方要学习啊。
留待解决的问题:此聊天室只能用于局域网以内,广域网就无法实现通信了,还要看看怎么实现远程的一个通信,不然这个就没有存在的意义了。
