我已经尝试并再次尝试将图像设置为默认值 (self.game.mario.get_sprite(0, 8, self.width, self.height)，但我似乎没有做任何工作。我已经尝试添加所有内容，从尝试将 x 速度设置为 0（没有工作），等等。既然你们能以某种方式解决这些问题，我真的需要帮助

默认图像不会神奇地恢复。需要保留默认图片，在animate开头设置默认图片：

class Player(pygame.sprite.Sprite):
    def __init__(self, game, x, y):
        # [...]

        self.default_image = self.game.mario.get_sprite(0, 8, self.width, self.height)
        self.image = self.default_image.copy()

        # [...]

    def animate(self):
        self.image = self.default_image.copy()

        # [...]

为什么当我在这个 pygame 脚本中没有按下任何东西时，精灵图像没有重置为默认值？

Why is the sprite image not resetting to default when I'm not pressing anything in this pygame script?
