General / Need help using deltaTime

« on: October 16, 2017, 08:37:19 am »

Hello, sorry I am new to SFML and C++ in general and have no clue what I am doing wrong.

#include <SFML/Graphics.hpp>
#include <iostream>
int main()
{
    int speed = 10;
    sf::RenderWindow window(sf::VideoMode(1920, 1080), "My window");
    sf::Texture texture;
    if (!texture.loadFromFile("asher.jpeg"))
    {
        std::cout << "Texture did not load" << std::endl;
    }
    sf::Sprite sprite;
    sprite.setTexture(texture);
    // run the program as long as the window is open
    while (window.isOpen())
    {
        sf::Event event;
        sf::Clock deltaClock;
        while (window.pollEvent(event))
        {
            float sf::Time dt = deltaClock.sf::Clock::restart.asSeconds;
            std::cout << dt << std::endl;
        }
        while (window.pollEvent(event))
        {
            // "close requested" event: we close the window
            if (event.type == sf::Event::Closed)
                {
                window.close();
                }

            if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
                {
                sprite.move(sf::Vector2f (5, 0));
                }
            if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left))
                {
                    sprite.move (sf::Vector2f(-5, 0));
                }
            if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up))
                {
                    sprite.move(sf::Vector2f(0, -5));
                }
            if (sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
                {
                    sprite.move(sf::Vector2f(0, 5));
                }


        }
        window.clear(sf::Color::Black);
        window.draw(sprite);
        window.display();
    }

Where it says,

float sf::Time dt = deltaClock.sf::Clock::restart.asSeconds;
std::cout << dt << std::endl;

I am trying to print the delta time so I can make movement look less choppy. I have been trying for hours but I can't figure out what is wrong with it. Any help would be appreciated, thank you.
