python - 创建一个组以在 Pygame 中添加我的类

Question

我目前正在 Pygame 中制作游戏，并且希望在我的屏幕上随机生成多个平台。但是，我似乎不知道如何创建一个组以便我可以一次绘制多个 Sprite 。我尝试过使用 super.__init__(self) 并将 self 替换为 (*Group) ，但它不起作用。我也刚刚尝试将其添加到组中。我应该如何创建我的组以及如何正确地将我的 Sprite 添加到其中？ 这是代码(我要添加的 Sprite 是在此处创建的，但未绘制):

这是我想要使用的类:

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)

另外，这里有两个要使用的图像:

Answer 1

你的类应该继承自 pygame.sprite.Sprite ，以便可以将它们放入 Sprite 组中，例如类平台(pg.sprite.Sprite):。不要忘记调用父类super().__init__()的__init__方法。然后创建 Sprite 组 (all_sprites = pg.sprite.Group()) 和 Sprite 实例，并调用组的 add 方法来添加 Sprite 。

然后您只需在主循环中调用 all_sprites.update() 和 all_sprites.draw(screen) 即可。

from random import randrange

import pygame as pg


class Platform(pg.sprite.Sprite):

    def __init__(self, x, y, width, height):
        super().__init__()
        self.image = pg.Surface((width, height))
        self.image.fill(pg.Color('dodgerblue1'))
        self.rect = self.image.get_rect(topleft=(x, y))


def main():
    screen = pg.display.set_mode((640, 480))
    clock = pg.time.Clock()
    all_sprites = pg.sprite.Group()  # This group that will contain all sprites.
    # You probably want to add the platforms to a separate
    # group as well, so that you can use it for collision detection.
    platforms = pg.sprite.Group()

    for _ in range(6):  # Create six platforms at random coords.
        platform = Platform(randrange(600), randrange(440), 170, 20)
        platforms.add(platform)
        all_sprites.add(platform)

    done = False

    while not done:
        for event in pg.event.get():
            if event.type == pg.QUIT:
                done = True

        all_sprites.update()

        screen.fill((30, 30, 30))
        all_sprites.draw(screen)

        pg.display.flip()
        clock.tick(30)


if __name__ == '__main__':
    pg.init()
    main()
    pg.quit()
