下面是我的两个实现版本

#version 1 this one works fine when I call it
class Asset(pygame.sprite.Sprite):
    def __init__(self, x_pos, y_pos, path=None, paths=None):
        super().__init__()
        self.x_pos = x_pos
        self.y_pos = y_pos

        if path:
            # if only one image
            self.image = pygame.image.load(path).convert_alpha()

        else:
            self.images = paths
            self.images_index = 0
            self.image = self.images[self.images_index]


        self.rect = self.image.get_rect(midbottom=(x_pos, y_pos))

class Player(Asset):

    def __init__(self, x_pos, y_pos):
        walking = [pygame.image.load('Images/graphics/Player/player_walk_1.png'),
                   pygame.image.load('Images/graphics/Player/player_walk_2.png')]
        super().__init__(x_pos=x_pos, y_pos=y_pos, paths=walking)
        self.vert_speed = 0
        self.jumping_image = pygame.image.load(
            'Images/graphics/Player/player_jump.png')
        self.time_in_air = 0
        self.ground = y_pos

然而，当我调用它时，这个函数不起作用（返回“TypeError:源对象必须是曲面”）

*最近的调用是\pyplay\sprite.py，第546行，绘制surface.blits（（spr.image，spr.rect）spr in sprites）

#version 2

class Asset(pygame.sprite.Sprite):
    def __init__(self, x_pos, y_pos, path=None, paths=None):
        super().__init__()
        self.x_pos = x_pos
        self.y_pos = y_pos

        if path:
            # if only one image
            self.image = pygame.image.load(path).convert_alpha()

        else:
            self.images = paths
            self.images_index = 0
            self.image = pygame.image.load(
                self.images[self.images_index]).convert_alpha()
            # The problem is right here

        self.rect = self.image.get_rect(midbottom=(x_pos, y_pos))


class Player(Asset):

    def __init__(self, x_pos, y_pos):
        walking = ['Images/graphics/Player/player_walk_1.png',
                   'Images/graphics/Player/player_walk_2.png']
        super().__init__(x_pos=x_pos, y_pos=y_pos, paths=walking)
        self.vert_speed = 0
        self.jumping_image = pygame.image.load(
            'Images/graphics/Player/player_jump.png')
        self.time_in_air = 0
        self.ground = y_pos

我期望这两个版本有相同的结果，但无法找出错误发生的原因。

有人能解释一下这两个版本的区别吗？我一直在寻找答案但真的找不到
