Makes sense, just tested it out and everything works.

Awesome, thank you.

Sorry.

There are 6 errors, all corresponding to the same line.

1. expected an identifier
2. variable "packet" is not a type name
3. variable "recipient" is not a type name
4. variable "port" is not a type name
5. C2143 syntax error: missing ';' before .                      (.send is it referring too*)
6. C2059 syntax error: '.'

This line of code isn't accepted by the compiler. (In the client code.)

sf::UdpSocket.send(packet, recipient, port);

So to simply put it, something is wrong with the code to send packets to the server.*

Network / Server and client UDP packet communication

« on: July 25, 2017, 11:43:04 pm »

Hello.

I got a little stuck when trying to setup a monitoring system sending all information to the server.

The idea is to use UDP and packets to simplify things, communication is only one-way.

This is what I've come up with so far, the idea is to be able to have a loop at the server side which spits out whatever comes in (cout), and if there is an error display that too.

#include <SFML/Network.hpp>
#include <iostream>

using namespace std;

int main() {

        sf::UdpSocket socket;

        // bind the socket to a port
        if (socket.bind(54000) != sf::Socket::Done) {
                cout << "There was an error binding to port 54000." << endl;
        }
        else {
                cout << "UDP socket is listening." << endl;
        }

        system("pause"); //Please ignore this, windows specific non-recommended stuff.
        return 0;
}

And on the client side I just want to send some information.

#include <SFML/Network.hpp>
#include <iostream>

using namespace std;

int main() {

        sf::IpAddress recipient = "127.0.0.1";
        unsigned short port = 54000;

        string message = "Hello";
        double speed = 10.3345;

        sf::Packet packet;

        packet << message << speed;
        sf::UdpSocket.send(packet, recipient, port); // This is the line VS 2015 don't like*

        system("pause"); //Please ignore this, windows specific non-recommended stuff.
        return 0;
}

My coding skills are rather basic, but I'm missing something here.

Thank you for anyone taking their time to help me out.

For the record, I used these pages when trying to set it up.
