Network / Client managing

« on: February 20, 2010, 04:29:34 pm »

Thanks a lot again.
I tried all the things you said in a lot of different variants. I still couldn't get it to work.

I tried all combinations of:
- storing pointers in my vector
- storing a pointer to the Socket in my class (sf::SocketTCP * Socket;)
- inherit from sf::NonCopyable
- making "sf::SocketTCP * Socket;" private

I don't know what to do.

Is there any other easy way to build a Client Manager except vectors?

Thank you for the help so far. But there is still a problem.

main.cpp

Code: [Select]

#include <iostream>
#include <vector>
#include <SFML/Network.hpp>
#include "player.h"
using namespace std;

vector<Player> Clients;
sf::Mutex GlobalMutex;

void Accept(void * UserData)
{
    sf::SocketTCP Listener;

    if (!Listener.Listen(1234))
        cerr << "Clouldn't Bind to port: " << 1234 << endl;

    while (true)
    {
        sf::SocketTCP Client;
        if (Listener.Accept(Client) == sf::Socket::Done)
        {
            GlobalMutex.Lock();
            Clients.push_back(Player(Client));
            GlobalMutex.Unlock();

            cout << "New connection" << endl;
        }
    }
   
    Listener.Close();
}

int main()
{
    sf::Thread Taccept(Accept);
    Taccept.Launch();

    while (true)
    {
        sf::Packet packet;
        sf::Int8 GameChar = 'P';
        packet << GameChar;
 
        GlobalMutex.Lock();
        for (unsigned int i = 0; i < Clients.size(); i++)
        {
            sf::Socket::Status status = Clients.at(i).Socket.Send(packet);
            cout << "Socket " << i << ": ";
            if (status == sf::Socket::Error)
                cout << "Error" << endl;
            else if (status == sf::Socket::Disconnected)
                cout << "Disconnected" << endl;
            else if (status == sf::Socket::NotReady)
                cout << "NotReady" << endl;
        }
        GlobalMutex.Unlock();
        sf::Sleep(0.5);
    }
    Taccept.Terminate();
    return 0;
}


player.h

Code: [Select]

#ifndef __PLAYER__
#define __PLAYER__

#include <SFML/Network.hpp>

class Player {
    public:
       
        ~Player()
        {
            Socket.Close();
        }

        Player(sf::SocketTCP Client)
        {
            Socket = Client;
        }

        sf::SocketTCP Socket;
};

#endif


main.cpp (simple Client)

Code: [Select]

#include <iostream>
#include <SFML/Network.hpp>
using namespace std;

int main()
{
    sf::SocketTCP Server;
   
    if (Server.Connect(1234, "127.0.0.1") == sf::Socket::Done)
    {
        while(1)
        {
            sf::Packet packet;
            sf::Socket::Status status = Server.Receive(packet);
            if (status == sf::Socket::Done)
            {
                sf::Int8  GameChar;
               
                packet >> GameChar;
                cout << "Message: " << GameChar << endl;
            }
            else if (status == sf::Socket::Disconnected)
            {
                cout << "Disconnected" << endl;
            }
            else if (status == sf::Socket::Error)
            {
                cout << "Error" << endl;
            }
            else if (status == sf::Socket::NotReady)
            {
                cout << "NotReady" << endl;
            }
            sf::Sleep(0.5);
        }
    }
    else
    {
        cout << "Failed to connect" << endl;
    }

    cin.get();

    return 0;
}


Now, the client is disconnected whenever "Clients.push_back(Player(Client));" is called. I really don't know why even after 30 minutes of debugging.
What I know is that the client says it is disconnected. The Server says there is an error when trying to send the packet.
Does it matter if I use pointers or not? Should I use them?

I hope you can help me.

        }

        sf::SocketTCP Socket;
        sf::IPAddress Address;

    private:

};

#endif

I know my Thread handling is bad. Just for testing purpose right now.
Once again: The first Socket that connects disconnects when "Listener.Accept(Clients.back().Socket);" is called the second time.

Btw: I am trying to make a pong(sfml sample) multiplayer mode

How do you know that the socket is disconnected? Do you store pointers or references to the elements of your array?

I know it is disconnected because the Client says it is when it tries to receive anything and the server confirms that when I try to send anything.

I do not store pointers. I create a Player object at the beginning and push it back each time I need a new object. After that I fill the element with the socket: "Listener.Accept(Clients.back().Socket); "

Hi!

I am writing a little Server application.
My Problem is that the Socket for my client disconnects when I am storing my Socket in a vector and I push back an other object.

Code:

Code: [Select]

vector<Player> Clients;

void Accept(void * UserData)
{
    sf::SocketTCP Listener;
    Player NewClient;

    if (!Listener.Listen(PORT))
        cerr << "Clouldn't Bind to port: " << PORT << endl;

    while (true)
    {
        Clients.push_back(NewClient);
        Listener.Accept(Clients.back().Socket);
   
        cout << "New connection. Address: "  << endl;
    }
   
    Listener.Close();
}

My player class:

Code: [Select]

class Player {
    public:
       
        ~Player()
        {
            Socket.Close();
        }

        sf::SocketTCP Socket;
        sf::IPAddress Address;

    private:

};

So the problem occurs when "Clients.push_back(NewClient);" is called the second time. I don't know why but the Socket "Clients.at(0).Socket" just disconnects.

I hope somebody can help me.

General / [soloved] Linking Problem - Debug Mode - Windows

« on: October 09, 2009, 04:31:23 pm »

Hello!

I am trying to compile a simple SFML application.
I am working with Visual Studio 2008 Express under Vista.

My steps:
1) Create a console Project
2) Write the code:

Code: [Select]

#include <SFML/Window.hpp>

int main()
{
    // Create the main window
    sf::Window App(sf::VideoMode(640, 480, 32), "SFML", sf::Style::Close);

    App.ShowMouseCursor(false);

    // Start main loop
    while (App.IsOpened())
    {
        // Process events
        sf::Event Event;
        while (App.GetEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                App.Close();

            // Escape key : exit
            if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
                App.Close();
        }

        App.Display();
    }

    return EXIT_SUCCESS;
}

3) Compile

I am linking to these libraries:
Debug:
sfml-system-s-d.lib sfml-window-s-d.lib
Release:
sfml-system-s.lib sfml-window-s.lib

Everything works in the Release mode. But there are some warnings when I compile in the Debug mode:

sfml-system-s-d.lib(Platform.obj) : warning LNK4099: PDB "vc90.pdb" wurde nicht mit "..\..\xxx\lib\vc2008\sfml-system-s-d.lib" oder an "xxx\win\Debug\vc90.pdb" gefunden; Objekt wird verknüpft, als ob keine Debuginformationen vorhanden wären.

Its kind of sad that it is in German

Well thats only a warning. I can run it without problems. But just one time. When I rebuild it the Program asks for a .dll:
MSVCP90D.dll

Very Strange...

Can anybody help me?
Greetings

Edit:
I solved it! I just had to build sfml by myseld and it worked fine.
