你好，看到你的代码中有一处错误：
csharp
Copy code
all_sprites.add(bullets)
应该是：
csharp
Copy code
all_sprites.add(bullet)
因为 bullets 是一个 Group 对象，而 bullet 是一个 Bullet 对象。应该将 bullet 添加到 all_sprites 中，而不是 bullets。
修改代码后应该是这样的：
scss
Copy code
def shoot(self):
if not(self.hidden):
bullet = Bullet(self.rect.centerx,self.rect.top)
all_sprites.add(bullet)
bullets.add(bullet)
shoot_sound.play()
希望能够解决你的问题。
