Network / Client server system help

« on: July 18, 2010, 03:21:43 pm »

So I got a system where the clients send their position to the server when they move and the server adds them to vector and should deliver the vector of all players back to player. So the sending system is ready, but how do I actually return the vector should I use udp sockets to send it back or something? Thanks in advance

Network / sf:Packet << operator overload problem

« on: July 02, 2010, 02:29:12 am »

I am in position now where I have to return the player vector to client so it can draw other people so would I need to do a new thread again dedicated to receive information from server? Any ways? Sorry for double post as I am posting from my iphone editin doesn't work. Thanks in advance.

Network / sf:Packet << operator overload problem

« on: July 01, 2010, 08:23:43 pm »

I actually tried with a one thread and it works pretty well, but I guess I still try non-blocking sockets, but does it make lag if it constantly checks where the other players are, it's the only solution I can make up.. Hope it doesn't lag.

This is what I got now:

player.h

Currently it only receives and sends socket but doesn't sort the players in vector, I guess I'll try to do it today. This is really nice learning btw. Thanks!

Network / sf:Packet << operator overload problem

« on: July 01, 2010, 07:44:29 pm »

Ok I solved it, thanks, but I got another problem, in the game loop my client has to get all the other players info from the server and draw them so they are in sync, but when it's doing it I can't move my char or anything.. Should I like put the character retriever thing into different thread or something.. I am so new to these things

Network / sf:Packet << operator overload problem

« on: July 01, 2010, 01:23:59 pm »

Hey, I was reading a tutorial on SFML site what says you can customize that packet thing to handle your own classes. I did add the operators there, I have defined those operators inside my player class and it still gives error?

Code is here
main.cpp

Code: [Select]


#include <SFML/Graphics.hpp>
#include <iostream>
#include "player.h"

int main()
{
    // Create the main rendering window
    sf::RenderWindow App(sf::VideoMode(800, 600, 32), "Samulin RPG");
std::cout << "Opening the main window for game! \n";
player p(App);


    // Start game loop
    while (&App)
    {

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

        // Clear the screen (fill it with black color)

So where should I actually put those operator overloads? As I put them inside my class and it doesn't seem to work..

Sorry meant to put player test; but anyways is there tutorial for making it a packet?

Network / Sending own object from client to server

« on: June 29, 2010, 01:48:27 am »

As I was reading the networking tutorial, here we send text to server

Code: [Select]

// Create the UDP socket
sf::SocketUDP Socket;

// Create bytes to send
char Buffer[] = "Hi guys !";

// Send data to "192.168.0.2" on port 4567
if (Socket.Send(Buffer, sizeof(Buffer), "192.168.0.2", 4567) != sf::Socket::Done)
{
    // Error...
}

So could I send object of my own to there like

// Create the UDP socket
sf::SocketUDP Socket;

// Create bytes to send
player * test;

// Send data to "192.168.0.2" on port 4567
if (Socket.Send(test, sizeof(Buffer), "192.168.0.2", 4567) != sf::Socket::Done)
{
    // Error...
}

So could I do like that?
