类型错误：参数1必须pygame.Surface，就不一一列举

Question

我正在运动的动画，因为我看到了一个YouTube用户解释如何做到这一点，但我得到这个错误：

TypeError: argument 1 must be pygame.Surface, not list

我的代码大约500条线。

错误是由一个精灵在具有列表为self.image属性您all_sprites组造成的。我刚刚印刷精灵的all_sprites.draw(screen)线

for sprite in all_sprites: 
    print(sprite, sprite.image) 

之前，它是玩家精灵其中有一个列表作为它的形象。

<Player sprite(in 1 groups)> [<Surface(40x25x32 SW)>, <Surface(40x25x32 SW)>] 

在load_movement_images方法定义self.standing_frame两个图像/ pygame.Surfaces的列表，并在__init__设置self.image到该列表中的第一项。但在animate方法中，您将self.image设置为整个列表而不是活动图像self.image = self.standing_frame，并导致错误。

class Player (pygame.sprite.Sprite): 
    # Sprite for the player 
    def __init__(self): 
     pygame.sprite.Sprite.__init__(self) 
     self.load_movement_images() 
     # self.image is the first image in the 
     # self.standing_frame list. 
     self.image = self.standing_frame[0] 
     # ... 

    def load_movement_images(self): 
     self.standing_frame = [no_mvmt_0, no_mvmt_1] 
     # ... 

    def animate(self): 
     now = pygame.time.get_ticks() 
     if not self.jumping and not self.running:
