Question

我目前正在Pygame制作游戏，并希望在整个屏幕中随机生成多个平台。但是，我似乎无法弄清楚如何创建一个组，以便我可以一次绘制几个精灵。我已尝试使用super.__init__(self)并将self替换为(*Group)，但它不起作用。我也试过把它添加到一个组中。我应该如何制作我的小组以及如何正确添加我的精灵呢？这是代码（我要添加的精灵在这里创建但未绘制）：

这是我想要使用的课程：

class Ground(object):
    def __init__(self,x,y,image):
        super.__init__(self)
        self.image = image
        self.x = x
        self.y = y
        self.rect = self.image.get_rect(topleft = (x,y))
    def draw(self):
        windowSurface.blit(self.image,(self.x,self.y))
platform1 = Ground((random.randint(0,800)),(random.randint(50,620)),lands)

此外，以下是两张图片：

Answer 1

您的类应继承自pygame.sprite.Sprite，以便将它们放入精灵组，例如： class Platform(pg.sprite.Sprite):。不要忘记调用父类__init__的{{1}}方法。然后创建精灵组（super().__init__()）和精灵实例，并调用组的all_sprites = pg.sprite.Group()方法来添加精灵。

然后您只需在主循环中调用add和all_sprites.update()。

all_sprites.draw(screen)

创建一个组以将我的类添加到Pygame中
