Unity在PC端的exe程序之间的通信
作者:互联网
这里记录一下注意点
IP地址
这里用的是内网的ip地址
如何在win10下查看自己电脑的内网IP地址
端口
端口随意,两个程序的端口相同就行了,我试了两个,24和112
下面的红框注意一致
UDP Send
UDP Receive
主要代码如下
发送端:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;
public class UDPSend: MonoBehaviour {
private string ip = "192.168.0.77"; //主机ip地址
private IPAddress ipAddress;
private IPEndPoint endPoint;
private Socket socket;
private EndPoint server;
private byte[] sendData; //发送内容,转化为byte字节
//发送函数
public void Send(int value) //参数不是字符串时转化为string
{
string msg = value.ToString(); //传递的值转化为string
try
{
ipAddress = IPAddress.Parse(ip); //ip地址
endPoint = new IPEndPoint(ipAddress, 112); //自定义端口号
socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
IPEndPoint sender = new IPEndPoint(IPAddress.Any, 112);
server = (EndPoint)sender;
sendData = new byte[1024]; //定义发送字节大小
sendData = Encoding.Default.GetBytes(msg); //对msg编码
socket.SendTo(sendData, sendData.Length, SocketFlags.None, endPoint); //发送信息
}
catch
{
}
}
}
接收端:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.Net;
using System.Net.Sockets;
using System.Threading;
using System.Text;
using UnityEngine.UI;
public class UDPReceive: MonoBehaviour
{
//public LeaderControll leaderControll; //外面要使用接收到信息的类
private IPEndPoint ipEndPoint;
private Socket socket;
private Thread thread;
private byte[] bytes; //接收到的字节
private int bytesLength; //长度
private string receiveMsg=""; //接收到的信息
[SerializeField]
private Text resultText;
void Start()
{
Init();
}
//初始化
private void Init() {
ipEndPoint = new IPEndPoint(IPAddress.Any, 112); //端口号要与发送端一致
socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
socket.Bind(ipEndPoint);
thread = new Thread(new ThreadStart(Receive)); //开启一个线程,接收发送端的消息
thread.IsBackground = true;
thread.Start();
}
//接收消息函数
private void Receive()
{
// IPEndPoint sender = new IPEndPoint(IPAddress.Any, 0);
IPEndPoint sender = new IPEndPoint(IPAddress.Any, 112);
EndPoint remote = (EndPoint)sender;
while (true)
{
bytes = new byte[1024];
bytesLength = socket.ReceiveFrom(bytes, ref remote);
receiveMsg = Encoding.ASCII.GetString(bytes, 0, bytesLength);
}
}
//实时接收消息
void Update()
{
// if (receiveMsg != "")
// {
// // leaderControll.Goto(receiveMsg); //外部使用接收到的字符串
// receiveMsg = "";
// }
if (receiveMsg != "")
{
print(" " +receiveMsg);
resultText.text = receiveMsg;
}
}
//关闭socket,关闭thread
private void OnDisable()
{
if (socket != null)
{
socket.Close();
}
if (thread != null)
{
thread.Interrupt();
thread.Abort();
}
}
}
