Unity通过TCP/IP协议进行通信

uinty项目中需要与C++编写的硬件进行通信，因此采用TCP/IP协议进行通信，主要实现了与服务器的连接、通信内容的发送以及断开连接等功能。
根据确定好的协议格式，编写需要发送的内容，将其转为字节流（byte[]）通过通信接口进行发送即可。具体代码如下：

using UnityEngine;
using System.Net;
using System.Net.Sockets;
using System;
using System.Text;
using UnityEngine.UI;public class TCPCommunication:MonoBehaviour
{private static string IP = “192.168.1.25”//通信连接的服务器地址private static int port = 8866;//端口号private static Socket socketSend;void Start(){connectServer();}///连接服务器private static void connectServer(){try{socketSend = new Socket(AddressFamily.InterNetwork, SocketType.Stream,ProtocolType.Tcp);IPAddress ip = IPAddress.Parse(IP);IPEndPoint point = new IPEndPoint(ip, Port);socketSend.Connect(point);Debug.Log("连接成功！")}catch(Exception ex)Debug.Log("连接失败！");}///发送消息public static void sendMessage(byte[] value){try{if(socketSend.Connected)sockedSend.Send(value);}catchDebug.Log("发送信息失败！");}///断开服务器连接private void OnDisable(){if(socketSend.Connected){try{socketSend.Shutdown(SocketShutdown.Both);socketSend.Close();}catch(Exception e)Debug.Log(e.Message);}}
}
