How to communicate properly between java server and gamemaker studio client
0
I have created a very very basic java server with tutorials. The goal is to let gamemaker studio 2 clients connect and communicate with that server. I have more experience with GML.
So the server is starting(java) up and the client(GMS2) is connecting succesfully. I have buildin some checks to make sure. If the client send a message to the server, the server never gets it, until the clients disconnect.
this is the java code:
import java.net.*;
import java.io.*;
public class GameServer {
public static void main(String args) throws IOException {
ServerSocket serverSocket = new ServerSocket(6666);
Socket client = serverSocket.accept();
BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));
PrintWriter out = new PrintWriter(client.getOutputStream(), true);
out.println("hello gamemaker studio: "); //the clients receive this message
while(true) {
System.out.println("in while loop");//the server console prints this message
String string = in.readLine();//keeps stuck on this
//after client disconnect, all messages the client has sent are displayed in the console
System.out.println("reading string:" + string);
if (string == null) { break; }
out.println("we have received this answer: " + string );
System.out.println("stopped");
}
}
}For some reason i don't know it is keeps stuck on this line:
String string = in.readLine();
I crafted a java client to test it. Everything works fine with a java client.
So there has to be something wrong with the gamemaker code

Are you sure that the client flushes their output and that it contains a newline (whichreadLine()is expecting)?

No, the server sent first the hello message to the client, the client receives that message and displays it. @MickMnemonic In gamemaker i have this to send a message: buffer_seek(buff, buffer_seek_start, 0); buffer_write(buff, buffer_string, "this is a test"); network_send_raw(server, buff, buffer_tell(buff));

I think you're not using the java part of the application correctly. I don't think that while should be there - I'm not experienced with Java, but I am with GameMaker, and I'm sure that way of sending messages sends a single packet (you can double check that with a packet sniffer). I'm doing it the same way and have made successful servers. Maybe try connecting with "packet-sender" as well (packetsender.com) so you can validate your Java server.
