Graphics / Help with a severe lag

« on: August 08, 2020, 09:00:46 pm »

This is my first time using SFML and while I was trying to make a game I noticed that whenever I ran the program, everything on my computer would start lagging. I opened the Task manager and it said that the program was using a lot of the performance. I have reproduced the bug so that it's easier to read the code.
I know the problem is in the the update function because when I comment out it's call, it doesn't cause the lag.
Here is the code

#include "SFML/Graphics.hpp"


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

public:
        Game()
                : window{ new sf::RenderWindow(sf::VideoMode(500, 500), "Game") }
        {

        }

        ~Game()
        {
                delete window;
        }

        void handleInputs()
        {
                sf::Event event;
                while (window->pollEvent(event))
                {
                        if (event.type == sf::Event::Closed)
                                window->close();
                }
        }

        void update()
        {
                window->clear();
                window->display();
        }

        void run()
        {
                while (window->isOpen())
                {
                        handleInputs();
                        update();
                }
        }
};


int main()
{
        Game game;
        game.run();

        return 0;
}
