How to make an Smooth Movement in C++, SFML

Question

I have a problem doing an smooth movement in c++ w/ sfml. Someone can make an algorithm to smooth move a shape / sprite by 15 px (the sprite / shape is 15 px) by pressing a button? Thanks.

Answer 1

Because many other programmers might want to know that, here it is, but next time ask a more precise question
Here's my way to make a smooth movement:

Take your initial movement, lets say 25, 15 per second
Make a loop like this:

void GameEngine::GameLoop()
{
    sf::Clock timer;
    sf::Time tickRate;

    sf::Vector2f movement(25.0,15.0); // Your movement vector

    while(/* wahtever */){
        tickRate = timer.restart();
        yourShape.move(movement * ((float)tickRate.asMilliseconds() / 1000)); //Move your shape depending on the time elapsed between two frame

        yourWindow.clear();
        yourWindow.draw(yourShape);
        yourWindow.display();
    }
}
