为什么我的矩形不绘制？ - 蟒蛇和pygame

Question

我有几个问题。 第一个：我确定下面的代码可以优化为不使用 4 个类，但是我不确定如何去做。 我正在尝试绘制一行和一列圆圈，其中较小的圆圈围绕每个圆圈的中心。 一排圆圈具有跟随较小轨道圆圈旋转的垂直线。 列遵循相同的模式，但线条是水平的。

到目前为止，我正在尝试使用四种类，一种用于水平圆，一种用于垂直圆形，一种用于水平矩形（使用矩形是因为我会检测碰撞），另一种用于垂直矩形。 我这样做是为了将信息传递给矩形，以便将它们的位置与轨道圆相对应。

第二个问题/问题：就像现在的代码一样，程序运行时不会显示垂直线。 我不完全确定为什么绘制水平线的代码运行正常并且它们匹配。

任何关于如何改善这一点的建议将不胜感激。

线条由矩形（ pygame.draw.rect() ）绘制。 绘制了垂直矩形，买你混淆了宽度和高度：

pg.draw.rect(surface, gray, (Target_Circle.x, 0, 800, 1))

pg.draw.rect(surface, gray, (Target_Circle.x, 0, 1, 800))

无论如何，我建议使用pygame.draw.line()来绘制线条：

class VerticalLine(HorizontalCircle):
    def __init__(self, surface, Target_Circle):
        self.surface = surface

    def draw(self,surface, Target_Circle):
        x = Target_Circle.x
        pg.draw.line(self.surface, gray, (x, 0), (x, self.surface.get_height()))
