我的sprite实例没有正确显示。

Question

我正在尝试实现一个设计，其中砖块列在操作屏幕的左边和右侧，数据/得分屏幕在顶部。砖类绘制一个具有适当大小的直冲填充砖柱空间。我为两边做了两个实例，但是只有左边的实例显示，它比我想要的地方低一半，如果我打印rect实例的坐标，它们就在正确的位置。有人能帮我理解我错过了什么/做错了什么吗？提前感谢您的帮助！

ActionScreen和Brick的左上角坐标保存在x和y属性中。但是，当您在image上绘图时，您必须使用相对于Surface的坐标，而不是相对于屏幕的坐标。曲面的左上角坐标总是(0，0)：

class ActionScreen():
    def __init__(self,ai_set):
        # [...]

        pg.draw.rect(self.image, ai_set.action_color, [0, 0, self.width, self.height])

class Brick(Sprite):
    def __init__(self,ai_set,x,y):
        # [...]

        pg.draw.rect(self.image,ai_set.brick_inside_color, [0, 0, self.width, self.height])

brick2的坐标是错误的：

def main():
    brick = Brick(ai_set, 0, ai_set.data_h)
    brick2 = Brick(ai_set, ai_set.action_w, ai_set.data_h)
    while True:
        gf_check_events() 
        gf_update(ai_set,screen, data_s, action_s, brick, brick2)
