    **import pygame**

##我的大学教授希望我这样做，即使他从未教过课程如何去做。那么当我不知道怎么做时，我怎么想这样做呢？

Answer 1

如果你看一下Player and Enemy的代码，你会发现它们非常相似 - 它们之间的唯一区别是：

桨位置
分数的x位置
获胜消息的名称
上下键

您可以将它们传递到Service方法并将它们存储为属性，然后在需要它们的方法中使用它们。

__init__

然后在def __init__(self, name, paddleX, scoreX, upKey, downKey): self.name = name self.paddleX = paddleX self.scoreX = scoreX self.upKey = upKey self.downKey = downKey ...代码中使用这些代码而不是代码现在使用的常量 - 所以代替Player或pygame.K_UP，您使用pygame.K_w。

然后而不是：

self.upKey

你可以为玩家和敌人传递正确的值：

player = Player()
enemy = Enemy()

然后您不再需要player = Player( name='player 1', paddleX=16, scoreX=16, upKey=pygame.K_w, downKey=pygame.K_s, ) enemy = Player( name='player 2', paddleX=SCR_WID - 16, scoreX=SCR_HEI + 92, upKey=pygame.K_UP, downKey=pygame.K_DOWN, )课程 - 它使用与Enemy相同的代码，但有一些不同的设置。希望有所帮助！

Python 3.2：我如何从拥有2个工作类改为只有1个工人阶级，但让Enemy + Player在1个工人阶级中工作？
