如何在SFML中删除对象

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 600), "SFML Delete Object Example");

    // 创建一个圆形对象
    sf::CircleShape circle(50);
    circle.setFillColor(sf::Color::Red);
    circle.setPosition(400, 300);

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

            if (event.type == sf::Event::KeyPressed)
            {
                // 当按下空格键时删除圆形对象
                if (event.key.code == sf::Keyboard::Space)
                {
                    window.remove(circle);
                }
            }
        }

        window.clear();
        window.draw(circle);
        window.display();
    }

    return 0;
}
