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 dataThreadStart ts = new ThreadStart(GetData);thread = new Thread(ts);thread.Start();}void GetData(){// Create the serverserver = new TcpListener(IPAddress.Any, connectionPort);server.Start();// Create a client to get the data streamclient = server.AcceptTcpClient();// Start listeningrunning = true;while (running){Connection();}server.Stop();}void Connection(){// Read data from the network streamNetworkStream nwStream = client.GetStream();byte[] buffer = new byte[client.ReceiveBufferSize];int bytesRead = nwStream.Read(buffer, 0, client.ReceiveBufferSize);// Decode the bytes into a stringstring 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 usingposition = ParseData(dataReceived);nwStream.Write(buffer, 0, bytesRead);}}// Use-case specific function, need to re-write this to interpret whatever data is being sentpublic static Vector3 ParseData(string dataString){Debug.Log(dataString);// Remove the parenthesesif (dataString.StartsWith("(") && dataString.EndsWith(")")){dataString = dataString.Substring(1, dataString.Length - 2);}// Split the elements into an arraystring[] stringArray = dataString.Split(',');// Store as a Vector3Vector3 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 exampleVector3 position = Vector3.zero;void Update(){// Set this object's position in the scene according to the position receivedtransform.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 sockethost, 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 datasock.connect((host, port))sock.sendall(data.encode("utf-8"))response = sock.recv(1024).decode("utf-8")print (response)finally:sock.close()
