顺时针旋转车轮而不旋转方法

Question

所以我做了一个项目，要求我逆时针旋转一个轮子。我这样做了。现在我被要求顺时针旋转它。我尝试了很多东西（比如减去10而不是在x2和y2变量上加10），但它总是会弄乱轮子的结构。我究竟做错了什么？这是构建方向盘的类：

import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JPanel;

class DrawShapes extends JPanel {
    private static final long serialVersionUID = 838002164453315800L;

    public void paintComponent(Graphics g) {
        g.setColor(Color.BLACK);
        g.fillRect(RotateFrame.oneX, RotateFrame.oneY, 6, 6);

        g.setColor(Color.GREEN);
        g.fillArc(RotateFrame.centerX, RotateFrame.centerY, 200, 200, 355, 10);
        g.fillArc(RotateFrame.centerX, RotateFrame.centerY, 200, 200, RotateFrame.x2 - 5, 10);
        g.setColor(Color.red);
        g.fillArc(RotateFrame.centerX, RotateFrame.centerY, 200, 200, RotateFrame.x2 + 85, 10);
        g.fillArc(RotateFrame.centerX, RotateFrame.centerY, 200, 200, RotateFrame.x2 + 45, 10);
        g.fillArc(RotateFrame.centerX, RotateFrame.centerY, 200, 200, RotateFrame.x2 - 45, 10);
        g.fillArc(RotateFrame.centerX, RotateFrame.centerY, 200, 200, RotateFrame.y2 - 5, 10);
        g.fillArc(RotateFrame.centerX, RotateFrame.centerY, 200, 200, RotateFrame.y2 + 85, 10);
        g.fillArc(RotateFrame.centerX, RotateFrame.centerY, 200, 200, RotateFrame.y2 + 45, 10);
        g.fillArc(RotateFrame.centerX, RotateFrame.centerY, 200, 200, RotateFrame.y2 - 45, 10);

        g.setColor(Color.black);
        g.drawArc(RotateFrame.centerX, RotateFrame.centerY, 200, 200, 0, 360);


    }
}

这是旋转方向盘的类：

                down = true;
                speedControl += 20;
            }
            if (up)
                oneY--;
