Question

所以，我正在制作一种声音类型的游戏，我希望他只是在表面上显示有点漂浮，直到我知道如何让他做碰撞和跑来跑去（之后）这使它成为一个很好的声音类型的游戏，速度奖励，水平等）我不知道我的代码有什么问题，我已经尝试改变我的Player类和精灵类的序列。我已经玩了好两个小时，并想知道它的语法化原因。

＆＃39; STR＆＃39;对象没有属性＆＃39; get_image＆＃39;

有关详细信息，请参阅我的评论。

变化：

class Player(pygame.sprite.Sprite):

    def __init__(self, x, y, width, height):

        super().__init__()

        #Sprite
        self.color_key = (72, 98, 78)
        sprite_sheet = 'spritesheet.png'
        self.image = sprite_sheet.get_image(x, y, width, height, self.color_key)

要：

class Player(pygame.sprite.Sprite):

    def __init__(self, x, y, width, height):

        super().__init__()

        #Sprite
        self.color_key = (72, 98, 78)
        sprite_sheet = SpriteSheet('spritesheet.png') # instantiate the class!
        self.image = sprite_sheet.get_image(x, y, width, height, self.color_key)

平台游戏有一个＆＃39; str＆＃39;对象没有属性＆＃39; get_image＆＃39;精灵错误，我不明白为什么
