Network / How do i send std::list?

« on: April 19, 2014, 03:57:44 pm »

Hello everyone,

im trying to pack a std::list into a packet. I´ve read the tutorial on extending packets to handle user types. But i have my problems to get it to work with std::list. The list contains bullets which are a struct with four float variables. I hope somebody can help me with this. 

struct BulletInfo
        {
                float PosX;
                float PosY;
                float SpeedX;
                float SpeedY;
        };

        //List
        std::list<BulletInfo>BulletList;

Thx for your help.
When i use this in a Singleplayer game it works pretty well. For example i sleep in the beginning of  loop for 10 milliseconds.
But when i use this in a Multiplayer game the Multiplayer is lagging. A movement from a character needs 2 seconds do go to the other player.
I set the sleep time to 1, 2 and 5 milliseconds but it doesnt helped. Have you any idea how i should do this with network stuff?
I know that sleeping every loop a constant time isnt perfect but i wanted to test it fast.

General / High Cpu Usage in Sfml 2.0 again

« on: December 29, 2012, 01:15:09 pm »

Hello everyone,

when i run this project my cpu usage is at 25%. Normally i think should be around 5%!
I had the same problem a few weeks ago and you helped me to fix it. There it was something with the joystick update.
It cant be the same problem because i commented out the line in the sfml code and recompiled it.

Here is the code:

#include <SFML/Graphics.hpp>

void main()
{
    sf::RenderWindow App(sf::VideoMode(1280, 720, 32), "Test");
    sf::Sprite SPlayer;
    sf::Texture TPlayer;
        sf::Clock clock;

        sf::Time ElapsedTime;

    TPlayer.loadFromFile("tank1.png");
    SPlayer.setTexture(TPlayer);
       
        App.setVerticalSyncEnabled(true);

    while(App.isOpen())
    {
        sf::Event Event;
        while(App.pollEvent(Event))
        {
            if(Event.type == sf::Event::Closed)
                App.close();
        }
                ElapsedTime = clock.restart();

                if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left))
                {
                        SPlayer.move(-50 * ElapsedTime.asSeconds(), 0);
                }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
                {
                        SPlayer.move(50 * ElapsedTime.asSeconds(), 0);
                }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up))
                {
                        SPlayer.move(0, -50 * ElapsedTime.asSeconds());
                }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
                {
                        SPlayer.move(0, 50 * ElapsedTime.asSeconds());
                }

        App.clear();

        App.draw(SPlayer);

        App.display();
    }
}

And here is an image of the output from very sleepy:

My Pc:
Intel Core i5 2500k

I can´t find Joystick::update in window.cpp and WindowImpl.cpp.
Should i comment out something different?

@eXpl0it3r
I used Very Sleepy to profile it.
I dont know what it mean but here is a screenshot of it: http://imageshack.us/photo/my-images/803/sleepyr.png/

I have a logitech mx 518 mouse with 800 dpi at default and i have no Joystick.

@Mario
I have tested the framerate with fraps and it shows 60 fps.
Also i have forced VSync at my Nvidea driver.

I tested both and i added them before the loop.

App.setVerticalSyncEnabled(true);

and

App.setFramerateLimit(60);

And no i dont used both at the same time

General / High Cpu usage SFML 2.0

« on: October 26, 2012, 01:33:30 pm »

Hello,

i have a problem with sfml 2.0!
On my pc and my laptop the cpu usage is very high (Pc: 25% / Laptop: 50%).
When i run the same project with a few changes with sfml 1.6 the cpu usage is normal(Pc: 4% / Laptop: 9%).
Here is the example code for SFML 2.0:

#include <SFML\Graphics.hpp>

void main()
{
        sf::Sprite SPlayer;
        sf::Texture TPlayer;
        sf::RenderWindow App(sf::VideoMode(1280, 720, 32), "Test");
        sf::Event Event;
        TPlayer.loadFromFile("test.png");
        SPlayer.setTexture(TPlayer);
        SPlayer.setPosition(500, 500);

        while(App.isOpen())
        {
                while(App.pollEvent(Event))
                {
                        if(Event.type == sf::Event::Closed)
                App.close();
                }

                App.clear();

                App.draw(SPlayer);

                App.display();
        }
}

In sfml 1.6 i use sf::image instead of sf::texture.
On both pc and laptop my os ist windows 7 (pc 64bit and laptop 32bit).
The pc has i5 2500k cpu and gtx 560ti graphics card. The laptop has a core 2 duo t6500 with 2.1 GHz and geforce 9600m gs graphics card.
On both i use visual studio express 2010 and there are no errors or warnings.

I hope someone could help me
