在sfml中用array定义圆的形状

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 600), "Circle Shape Example");

    sf::CircleShape circle(50); // 创建一个半径为50的圆形对象
    circle.setPosition(400, 300); // 设置圆的位置
    circle.setFillColor(sf::Color::Red); // 设置圆的填充颜色

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

        window.clear();
        window.draw(circle); // 绘制圆形
        window.display();
    }

    return 0;
}
