缩放窗口时如何在应用程序中修复背景

Question

Help with sfml, it is necessary to make so that the background application when scaling is not changed,

int main()
{
    ....
    View view;
    view.reset(FloatRect(0, 0, 1200, 700));
    float zoom = 1.0f;

    while (window.isOpen())
    {   
        ProcessEvents(window, clickState, zoom, view);
        ...
        window.setView(view);
        window.draw(bg);
        window.draw(vecBody.at(0).sprite);
        window.draw(text);  
    }
}

Without zoom

With zoom

Answer 1

When you scale the view in or out, you need to adapt the background sprite to scale out or in (ie the inverse operation you applied on the view).

Have a look at sf::Sprite::setScale .
