Unity教程：如何制作简易聊天室

发表于2017-03-26

很多项目都要做聊天系统，方便玩家用户之间的交流。那么在unity中如何建立制作一个简易聊天室呢，这就需要利用 Unity 中内建的 Network 来简易说明。

首先新增一个 Server.cs

using UnityEngine;  
using System.Collections;  
 
public class Server : MonoBehaviour
{  
    //The number of allowed incoming connections
    public int connections = 4;
    //The port number we want to listen to
    public int port = 25000;
     
    void OnGUI()
    {
        //Network state
        switch (Network.peerType)
        {
        //Disconnected
        case NetworkPeerType.Disconnected:
            CreateServer();
            break;
        //In server
        case NetworkPeerType.Server:
            OnServer();
            break;
        }
    }
 
    //Create server button
    void CreateServer()
    {
        if (GUILayout.Button ("Create Server"))
        {
            //Initialize the server
            //Network.InitializeServer(int connections, int listenPort, bool useNat); 
            Network.InitializeServer( connections, port, false );
        }
    }
 
    //Wait for client and display the client information
    void OnServer()
    {
        GUILayout.Label ( "The Server is startting now, waiting for client connecting." );
        int length = Network.connections.Length;
 
        for (int cnt = 0; cnt < length; cnt++)
        {
            GUILayout.Label( "-------------------------" );
            GUILayout.Label( "Client " + cnt );
            GUILayout.Label( "Client IP : " + Network.connections[cnt].ipAddress );
            GUILayout.Label( "Client Port : " + Network.connections[cnt].port );
        }
    }
}

Server.cs 脚本主要是用来初始化伺服器

这裡所使用的方法都是 Unity API

这个脚本是用来初始化伺服器提供客户端连线

接下来新增 Client.cs

using UnityEngine;  
using System.Collections;  
  
public class Client : MonoBehaviour
{
    public string IP = "127.0.0.1";
  
    //The port number we want to listen to
    public int port = 25000;
  
    //The total message
    private string message;
    //The send message
    private string sendMessage = "";
  
    //The client name
    private string name = "";
  
    void OnGUI()
    {   
        switch (Network.peerType)
        {   
        case NetworkPeerType.Disconnected:
            StartConnect();
            break;
        case NetworkPeerType.Client:
            OnClient();
            break;  
        }
    }
  
    void StartConnect()
    {
        if (GUILayout.Button ("Connect to server"))
        {       
            Network.Connect( IP, port );
        }
    }
  
    void OnClient()
    {
        name = GUILayout.TextField( name, 10 );
        sendMessage = GUILayout.TextField(sendMessage, 25);
          
        if (GUILayout.Button ("Send Message"))
        {
            //Network send function
            //networkView.RPC(string name, RPCMode mode, params object[] args); 
            GetComponent().RPC( "ReceiveMessage", RPCMode.All, name, sendMessage );
            sendMessage = "";
        }
          
        GUILayout.Label ( "Message : " );
        GUILayout.Label ( message );
    }
  
    //Network receive function
    [RPC]
    void ReceiveMessage(string n, string msg, NetworkMessageInfo info)
    {   
        message += n + " : " + msg + "n";
    }
  
}
