Question

我再一次在一个学校项目上工作，我很难过，我觉得应该很容易......

我有代码工作;它没有崩溃，但它也没有blitting。我创造了第一人称射击游戏风格的游戏，使用Sprites作为＆＃34; Zombie目标＆＃34;我在Zombie Class中有更新来移动图像，但我知道我有多个问题..
一如既往，我只是在寻求一些方向。

非常感谢！

请参见pygame.sprite.Group.draw()：

将包含的Sprite绘制到Surface参数。这会将Sprite.image属性用于源曲面，并将Sprite.rect用于位置。

您根本不需要类self.x中的属性self.y，slef.img，Zombie。将位置存储在.rect属性中，将图像存储在.image属性中：

class Zombie(pygame.sprite.Sprite):

    def __init__(self):
        pygame.sprite.Sprite.__init__(self)

        self.ani_speed_init = 8
        self.ani_speed = self.ani_speed_init
        self.ani = glob.glob("zombie_walk_r*.png")
        self.ani.sort()
        self.ani_pos = 0
        self.ani_max = len(self.ani) - 1
        self.image = pygame.image.load(self.ani[1])
        
        x = random.randrange(0, screen.get_width())
        y = random.randrange(0, screen.get_height())
        self.rect = self.image.get_rect(center = (x, y))
    
    def update(self, pos):
        pass

此外，这是Indentation的问题。您需要在应用程序循环中而不是在应用程序循环后绘制场景并更新显示：

def main():
    # [...]

    while keepGoing:
        clock.tick(30)
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                keepGoing = False
            if event.type == pygame.MOUSEBUTTONDOWN:
                killShotSpot = pygame.mouse.get_pos()
                shoot(killShotSpot)
                pygame.draw.circle(background,(255,0,0),killShotSpot,3,0)

        #-->| INDENTATION

        allSprites.clear(screen, background)
        allSprites.update()
        allSprites.draw(screen)
        pygame.display.flip()

Sprite Group不会blit
