SFML projects / Game framework : Network-System-Graphics | Feedback appreciated

« on: September 28, 2016, 10:30:48 am »

Hello,

I've finished my project for more than two month now but never got any feedback on it so it will be appreciated.

Link: https://github.com/Shinao/JustAGame

Basically what I wanted to do is a framework for all my mini games, I've had a lot of ideas and simple things to create but I had to redo some things every time and if I wanted to make it multiplayer it was really painful.

What's great about it is the simplicity to integrate a new game. The sample Tic Tac Toe is a shared library that will be loaded on runtime by the game framework when you join a server, if you don't have this game it will download it so that you don't have to keep updating your games manually to the clients.

I don't really use it anymore but some classes can be useful for some people since it's cross-platform. It probably have some bugs since I could not test it on a large scale.

Do you guys have also some libraries/classes that you re-use all the time ? What are they ?

Good day.

Network / SocketSelector isReady always return false

« on: April 04, 2014, 07:08:23 am »

Hi,

Here is my minimal example
./a.out foo
will launch the server
and ./a.out will launch the client
The client will send a udp message to the server which will display received.
But if we uncomment the isReady function, then we can see that it always return false.

What am I doing wrong ?
By the way, I just pulled the git repository, so I've got the last 'version'.

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

void    server();
void    client();

int     main(int ac, char **av)
{
  if (ac > 1)
    server();
  else
    client();
}

void    server()
{
  sf::SocketSelector _listener;
  sf::UdpSocket _socket;

  _listener.add(_socket);
  if (_socket.bind(25052) != sf::Socket::Done)
  {
    std::cout << "can't bind" << std::endl;
    return ;
  }

  char buffer[1024];
  std::size_t received = 0;
  sf::IpAddress sender;
  unsigned short port;

  _socket.setBlocking(true);
  while (1)
  {
    // if (_listener.isReady(_socket))
    // {
      _socket.receive(buffer, sizeof(buffer), received, sender, port);
      std::cout << "received" << std::endl;
    // }

    sf::sleep(sf::milliseconds(2000));
  }
}

void    client()
{
  sf::UdpSocket _socket;

  if (_socket.bind(52025) != sf::Socket::Done)
  {
    std::cout << "can't bind" << std::endl;
    return ;
  }

  _socket.send("ping", 5, sf::IpAddress::Broadcast, 25052);
}
