well,

I formulated badly my post, if I use any of them I get the frame skipping ..

I have tested same example in AMD PC and an Intel one.. same result..

If I don't use any of them it works fine...

 I am don't know what is it..

General / setFramerateLimit() && setVerticalSyncEnabled()

Hi all,

So I am getting weird results when moving my character is not smooth.. it actually skips at the middle center of the window.. When I disable both functions it doesn't appear to skip anymore..

I try to do bare bone to see if it was something I did in the code, I found this in the forum and would like to know if you see frame skipped using the example below because in my computer it seems to do..

thanks..

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 600), "Test");
    window.setVerticalSyncEnabled(true);

    sf::Vector2f player1(10, 10);
    sf::RectangleShape paddle1(sf::Vector2f(10, 30));

    sf::Clock clock;
    sf::Time time;

    float dt = 0;
    const int speed = 500;

    // Start the game loop
    while (window.isOpen())
    {

        // Poll for events
        sf::Event event;
        while (window.pollEvent(event))
        {
            // Close window : exit
            if (event.type == sf::Event::Closed)
                window.close();

            // Escape pressed : exit
            if (event.type == sf::Event::KeyPressed && event.key.code == sf::Keyboard::Escape)
                window.close();
        }


        // Check for user input
        if (sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
            player1.y += speed * dt;

        // Check for user input
        if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up))
            player1.y -= speed * dt;

        if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left))
            player1.x -= speed * dt;

        if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
            player1.x += speed * dt;


        // Restart the clock and get the delta time
        time = clock.restart();
        dt = time.asSeconds();


        // Update the object positions
        paddle1.setPosition(player1.x, player1.y);

        // Clear screen
        window.clear();

        // Draw the sprites
        window.draw(paddle1);

        // Update the window
        window.display();
    }

    return EXIT_SUCCESS;
}

Hi,
 To get the size of the window mainly , i dont like passing reference and having a global reference of sf::window come handy i guess. I am still learning SFML.

Thanks a lot,

 But is not that I want to draw the player, instead I want to have some public functions in the Player class that are dependent of the intance the window and I dont want to pass it as parameter refence to all clases that I want to create..

General / sf::RenderWindow reference main class availble gobally in second Class

Hello there all,

 I am very new to CPP, but I have a question I couldn't get it settle searching..

private:

class Game {
private:
    sf::RenderWindow window;
public:

    Game() {
        this->window.create(sf::VideoMode(600, 500), this->name, sf::Style::Close);

        this->player(this->window);// instantiated window

    }
    Player player;
};

class Player {
private:
    sf::RenderWindow w;
public:
    Player(sf::RenderWindow& window)
        : w(window)
    {

        this->w; // window reference from Game class Available globally in Player Class this->w

    }
};

int main() {
        Game game;
        return 0;
}
 

I don't want to be passing reference of window on every class method in Player class and I don't want to pass it in main.cpp and pass it as reference from a normal object to both classes because I know works using the list initiator in the constructors.
