我有这段代码。[敌人.py].

[game.py](不是完整的代码，但无论如何，这是我们需要知道的(。
from enemy import Enemy
enemy = Enemy()
enemy.enable_ai()
每5秒钟它必须移动一次，但它根本不移动。注意，该函数会被调用。
该怎么办？⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
哦，我解决了。我们需要使用self.x，而不是self.position.x。
