TCP-IP Connection between Matlab and Unity3D
You can check the real question from https://www.mathworks.com/matlabcentral/answers/196774-connection-between-matlab-and-unity3d
First*, Matlab as server and unity as client
// matlab code
clc
clear all
tcpipServer = tcpip('0.0.0.0',55000,'NetworkRole','Server');
while(1)
data = membrane(1);
fopen(tcpipServer);
rawData = fread(tcpipServer,14,'char');
for i=1:14 rawwData(i)= char(rawData(i));
end
fclose(tcpipServer);
end
// Unity C# code
using System.Collections;
using System.Net;
using System.Net.Sockets;
using System;
using System.IO;
public class Socket : MonoBehaviour {
// Use this for initialization
internal Boolean socketReady = false;
TcpClient mySocket;
NetworkStream theStream;
StreamWriter theWriter;
StreamReader theReader;
String Host = "localhost";
Int32 Port = 55000;
void Start () {
setupSocket ();
Debug.Log ("socket is set up");
}
// Update is called once per frame
void Update () {
}
public void setupSocket() {
try {
mySocket = new TcpClient(Host, Port);
theStream = mySocket.GetStream();
theWriter = new StreamWriter(theStream);
socketReady = true;
//writeSocket("yah!! it works");
Byte[] sendBytes = Encoding.UTF8.GetBytes("yah!! it works"); //--> if the above line doesn't work use this line instead
mySocket.GetStream().Write(sendBytes, 0, sendBytes.Length); // with this one also
Debug.Log ("socket is sent");
}
catch (Exception e) {
Debug.Log("Socket error: " + e);
}
}
}
Second, unity as server and Matlab as client
//Unity C# code
using UnityEngine;
using System.Collections;
using System.Net;
using System.Net.Sockets;
using System.Linq;
using System;
using System.IO;
using System.Text;
public class readSocket : MonoBehaviour {
// Use this for initialization
TcpListener listener;
String msg;
void Start () {
//listener=new TcpListener (55001);
listener = new TcpListener(IPAddress.Parse("127.0.0.1"), 55001);
listener.Start ();
print ("is listening");
}
// Update is called once per frame
void Update () {
if (!listener.Pending ())
{
}
else
{
print ("socket comes");
TcpClient client = listener.AcceptTcpClient ();
NetworkStream ns = client.GetStream ();
StreamReader reader = new StreamReader (ns);
msg = reader.ReadToEnd();
print (msg);
}
}
}

//1) Your unity C# code works only if you name it "readSocket" (as specified at line 10 of the code before the "MonoBehaviour" command.
//2) In the TcpListener command (line 20 of the code) within the parenthesis you have to specify the ip number in this way: IPAddress.Parse("127.0.0.1").
//Then you have to write the server port number (55001) separated by a comma.
listener = new TcpListener(IPAddress.Parse("127.0.0.1"), 55001);
//3) The C# code in unity works only once you drag the C# file on the top the "Main Camera" file that you can find in the "Sample scene" file.
//Matlab code
clc
clear all
tcpipClient = tcpip('127.0.0.1',55001,'NetworkRole','Client');
set(tcpipClient,'Timeout',30);
fopen(tcpipClient);
a='yah!! we could make it';
fwrite(tcpipClient,a);
fclose(tcpipClient);
//in each implementation the server should runs first before the client otherwise you will get the below error
//Connection refused:in Matlab or remote machine actively refuse the connection in unity
