用easyx和类画一面盾牌

以下是用EasyX图形库和C++类来画一面盾牌的示例代码：

#include <graphics.h>
#include <conio.h>

class Shield {
public:
    Shield(int x, int y, int r, COLORREF color) : m_x(x), m_y(y), m_r(r), m_color(color) {}
    void Draw() {
        setfillcolor(m_color);
        setlinecolor(WHITE);
        fillellipse(m_x, m_y, m_r, m_r);
        setfillcolor(WHITE);
        int inner_r = m_r / 2;
        fillellipse(m_x, m_y, inner_r, inner_r);
        setfillcolor(m_color);
        int shape[8] = { m_x - m_r / 2, m_y, m_x - m_r / 3, m_y - m_r / 2, m_x, m_y - m_r / 3, m_x + m_r / 3, m_y - m_r / 2 };
        fillpolygon(shape, 4);
        int shape2[8] = { m_x - m_r / 2, m_y, m_x - m_r / 3, m_y + m_r / 2, m_x, m_y + m_r / 3, m_x + m_r / 3, m_y + m_r / 2 };
        fillpolygon(shape2, 4);
    }
private:
    int m_x, m_y, m_r;
    COLORREF m_color;
};

int main() {
    initgraph(640, 480);
    Shield shield(320, 240, 100, RED);
    shield.Draw();
    getch();
    closegraph();
    return 0;
}

运行以上代码后，会在屏幕上显示一面红色的盾牌。
