为什么当我没有在这个pygame脚本中按下任何内容时，精灵图像没有重置为默认值？

我已经尝试了一次又一次地将图像设置为默认的(self.game.mario.get_sprite(0, 8, self.width, self.height)，但我似乎没有做任何工作。我试过添加一切，从试图使x速度为0(不工作)，喜欢，一切。既然你们有办法解决这个问题，我真的需要帮助

默认图像不会神奇地恢复。您需要保留默认映像，并在animate开头设置默认映像:

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()
# [...]
