Hi,
i'm trying to build sfml 2.0 ...
according to tutorial i generated CodeBlock project file, but when i open it and try to build i get this:

Code: [Select]

Network / my first network program

In that pic he posted u can see some clients and a server exchanging packets. Problem is the one I described previously - server is already receiving/sending ~134th packet to clients but the last packet clients received is ~80-90th.

yup thats the problem..
someone help please?! ;(

Network / UDP Server - Handling multiple connections

« on: September 16, 2010, 09:14:28 pm »

i was asking something similar few topicks lower
you dont need selector if you are using only one socket

and here is my attempt to creat multiple client <-> server application with UDP, but it lags :/

Network / [SOLVED] Server and client

« on: September 16, 2010, 06:21:24 pm »

server:

Code: [Select]

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


int main()
{
    const unsigned short Port = 2435;

    sf::SocketUDP Server;
    if (!Server.Bind(Port))
    {
        std::cout << " error" << std::endl;
    }

    sf::Packet Packet;
    sf::IPAddress ClientAddress;
    unsigned short ClientPort;
    Server.Receive(Packet, ClientAddress, ClientPort);

    int a;
    Packet >> a;
    std::cout << "packet : " << a << " from "<< ClientAddress <<" port: "<< ClientPort << std::endl;

    a=12345;
    Packet.Clear();
    Packet << a;
    Server.Send(Packet, ClientAddress, ClientPort);

    std::cin.ignore(10000, '\n');
    Server.Close();
    return EXIT_SUCCESS;
}


client:

Code: [Select]

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


int main()
{
    const unsigned short Port = 2400;

    sf::SocketUDP Client;
    if (!Client.Bind(Port))
    {
        std::cout << " error" << std::endl;
    }

    sf::Packet Packet;
    sf::IPAddress ServerAddress="127.0.0.1";
    unsigned short ServerPort=2435;

    int a;
    a=54321;
    Packet << a;
    Client.Send(Packet, ServerAddress, ServerPort);

    Packet.Clear();
    Client.Receive(Packet, ServerAddress, ServerPort);

    Packet >> a;
    std::cout << "packet : " << a << " from "<< ServerAddress <<" port: "<< ServerPort << std::endl;

    std::cin.ignore(10000, '\n');
    Client.Close();
    return EXIT_SUCCESS;
}


 this will do?

ok.. i rewrote my masterpiece
server:

Code: [Select]

client:

Code: [Select]

struct client_s

            float xx,yy;
            Packet >> nn >> xx >> yy;
            client[nn].x=xx;
            client[nn].y=yy;
        }

        if(Clock.GetElapsedTime()-Send_Time>0.3)
        {
            Send_Time=Clock.GetElapsedTime();
            y++;
            Packet.Clear();
            Packet << x << y;
            Client.Send(Packet, ServerAddress, 2323);
        }
    }
    Client.Close();
    return EXIT_SUCCESS;
}


every time clients sends a packet, Y is increased by 1
When server receives a packet from client, it stores it into array and sends whole array to all clients, so array at server and client should be +/- equal
but i get this:
Is it becouse I run 4 clients at 1 pc or I do something stupid at program?

Network / my first network program

« on: September 13, 2010, 09:02:16 pm »

hey,
i want to make simple program that receives coordinates from client and sends them to other clients.
so far i've made this: http://www.failiem.lv/down.php?i=aofrvh&n=multi_graf.rar
can someone take a look at it?  :roll:

everything seams to be working fine if only one client is "connected"
that sprite who looks like shadow is player coords which are sent to server and received back..

BUT when 2 clients are active and moving, its starts to lag :?
Server log shows those received coordinates and the same are sent back, but client displays them later, because there are already dozens of coordinates waiting in line to be displayed.

What am I doing wrong?

and another question - how to statically link  libgcc_s_dw2-1.dll
i trayed  -static-libgcc but it doesn't work :/

Network / UDP and Selector

« on: September 12, 2010, 02:35:06 pm »

It's not, as long as you don't share variables between threads. Have you read the corresponding tutorial?

you think this:
http://www.sfml-dev.org/tutorials/1.6/system-threads.php
i haven't read it :lol:

so i just need to aad this: Server.SetBlocking(false); ?
