如何在调用函数时将对象绘制到sfml窗口？

sf::RenderWindow window(sf::VideoMode(width, height), "SFML Window");

void drawObject(sf::RenderWindow& window, const sf::Drawable& object) {
    window.draw(object);
}

sf::CircleShape circle(radius);
circle.setPosition(x, y);
circle.setFillColor(sf::Color::Red);

while (window.isOpen()) {
    sf::Event event;
    while (window.pollEvent(event)) {
        if (event.type == sf::Event::Closed)
            window.close();
    }

    window.clear();
    drawObject(window, circle);
    window.display();
}
