TypeError：无法创建一致的方法解析顺序（MRO） [英] TypeError: Cannot create a consistent method resolution order (MRO)

问题描述

这是我计划用于游戏的代码。但它抱怨MRO错误。我不知道为什么。有人能为我解释一下吗？非常感谢。

This is the code which I plan to use for my game. But it complains for an MRO error. I don't know why. Can someone explains for me? Many thanks.

class Player:
    pass

class Enemy(Player):
    pass

class GameObject(Player, Enemy):
    pass

g = GameObject()

推荐答案

您的 GameObject 继承自玩家 和 敌人。因为 Enemy 已经继承自 Player Python现在无法确定要查找方法的类第一; 播放器，或 Enemy ，它将覆盖播放器。

Your GameObject is inheriting from Player and Enemy. Because Enemy already inherits from Player Python now cannot determine what class to look methods up on first; either Player, or on Enemy, which would override things defined in Player.

您不需要在此处命名 Enemy 的所有基类;只从这一个类继承：

You don't need to name all base classes of Enemy here; just inherit from that one class:

class GameObject(Enemy):
    pass

Enemy 已包含播放器，你不需要再包括它。

Enemy already includes Player, you don't need to include it again.
