初步接觸了Socket,現(xiàn)使其與Unity相結(jié)合，做成一個(gè)簡(jiǎn)單的客戶(hù)端之間可以互相發(fā)送消息的一個(gè)Test。下面話不多說(shuō)了，來(lái)一起看看詳細(xì)的介紹吧。
方法如下：
首先，是服務(wù)端的代碼。
創(chuàng)建一個(gè)連接池，用于存儲(chǔ)客戶(hù)端的數(shù)量。

{
if (!isUse)
{
return;
}
else
{
Console.WriteLine("斷開(kāi)連接" + GetAdress());
socket.Close();
isUse = false;
}
}
}
}對(duì)象池創(chuàng)建完成后，需要在創(chuàng)建一個(gè)連接類(lèi)，用來(lái)維護(hù)客戶(hù)端的連接。

}最后是創(chuàng)建一個(gè)Unity的工程，搭建一個(gè)簡(jiǎn)單的頁(yè)面，通過(guò)下面的代碼你可以了解需要哪些組件

using System.Collections.Generic;
using System;
public class net : MonoBehaviour

const int buffer_Size = 1024;
public byte[] readBuff = new byte[buffer_Size];
void FixedUpdate()
{
recvText.text = recvStr;
}
//連接服務(wù)器（需要一個(gè)Button觸發(fā)）
public void Connetion()
{

socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
string host = hostInput.text;

socket.BeginReceive(readBuff, 0, buffer_Size, SocketFlags.None, ReceiveCb,socket);
}

if (recvStr.Length > 300) recvStr = "";
recvStr += socket.LocalEndPoint.ToString()+str + "\n";
Debug.Log("12346");
socket.BeginReceive(readBuff, 0, buffer_Size, SocketFlags.None, ReceiveCb, socket);
}catch(SocketException ex)
{

}
}
