Movement Without Framerate Limit C++ SFML

Question

I'm working an making a game in SFML right now, but I am getting stuck on movement without a framerate limit. Right now the only way I have figured out how to get consistent framerate on all computers is by using

window.setFramerateLimit(30);

I want to find a way to not have a framerate cap so it does look better on better computers and so that if anybody has a really slow computer, they can still play the game. What would be the best way to do this.

Answer 1

You should pass the time that has elapsed since the last frame to the object that needs to be drawn, and then calculate the space the object has to move, like this:

sf::Clock clock;
int speed = 300;


//Draw func that should be looped
void Draw()
{
    sf::Time elapsedTime = clock.restart();
    float tempSpeed = elapsedTime.asSeconds() * speed;
    drawnObject.move(tempSpeed, 0);
    drawnObject.draw(window);
}

This way, the 'drawnObject' will move 300 (pixels?) per second to the right regardless of the FPS
