Unity设置:

  • 打开Unity项目。
  • 创建一个空的GameObject,并附加一个新的脚本TCPReceiver
    ?
  • using System.Net;
    using System.Net.Sockets;
    using System.Text;
    using UnityEngine;
    using System.Threading;
    
    public class MyListener : MonoBehaviour
    {
        Thread thread;
        public int connectionPort = 25001;
        TcpListener server;
        TcpClient client;
        bool running;
    
    
        void Start()
        {
            // Receive on a separate thread so Unity doesn't freeze waiting for data
            ThreadStart ts = new ThreadStart(GetData);
            thread = new Thread(ts);
            thread.Start();
        }
    
        void GetData()
        {
            // Create the server
            server = new TcpListener(IPAddress.Any, connectionPort);
            server.Start();
    
            // Create a client to get the data stream
            client = server.AcceptTcpClient();
    
            // Start listening
            running = true;
            while (running)
            {
                Connection();
            }
            server.Stop();
        }
    
        void Connection()
        {
            // Read data from the network stream
            NetworkStream nwStream = client.GetStream();
            byte[] buffer = new byte[client.ReceiveBufferSize];
            int bytesRead = nwStream.Read(buffer, 0, client.ReceiveBufferSize);
    
            // Decode the bytes into a string
            string dataReceived = Encoding.UTF8.GetString(buffer, 0, bytesRead);
            
            // Make sure we're not getting an empty string
            //dataReceived.Trim();
            if (dataReceived != null && dataReceived != "")
            {
                // Convert the received string of data to the format we are using
                position = ParseData(dataReceived);
                nwStream.Write(buffer, 0, bytesRead);
            }
        }
    
        // Use-case specific function, need to re-write this to interpret whatever data is being sent
        public static Vector3 ParseData(string dataString)
        {
            Debug.Log(dataString);
            // Remove the parentheses
            if (dataString.StartsWith("(") && dataString.EndsWith(")"))
            {
                dataString = dataString.Substring(1, dataString.Length - 2);
            }
    
            // Split the elements into an array
            string[] stringArray = dataString.Split(',');
    
            // Store as a Vector3
            Vector3 result = new Vector3(
                float.Parse(stringArray[0]),
                float.Parse(stringArray[1]),
                float.Parse(stringArray[2]));
    
            return result;
        }
    
        // Position is the data being received in this example
        Vector3 position = Vector3.zero;
    
        void Update()
        {
            // Set this object's position in the scene according to the position received
            transform.position = position;
        }
    }

    Python设置:

  • 如果尚未安装socket库,安装(pip install socket
  • 创建一个Python脚本send_data.py
    ?
    import socket
    
    host, port = "127.0.0.1", 25001
    data = "1,2,3"
    
    # SOCK_STREAM means TCP socket
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    
    try:
        # Connect to the server and send the data
        sock.connect((host, port))
        sock.sendall(data.encode("utf-8"))
        response = sock.recv(1024).decode("utf-8")
        print (response)
    
    finally:
        sock.close()
