使用类的简单基于文本的游戏。 尝试为库存中是否有特定项目创建一个基本循环。 然后开门

Question

我的问题实际上发生在 LockedRoom() 中：

python抛出的错误是：

Traceback (most recent call last):
  File "C:\Users\Tank\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Enthought\CastleGame1.py", line 479, in <module>
    a_game.play()
  File "C:\Users\Tank\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Enthought\CastleGame1.py", line 33, in play
    next_scene_name = current_scene.enter()
  File "C:\Users\Tank\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Enthought\CastleGame1.py", line 147, in enter
    has_key = "key" in Person.items
AttributeError: class Person has no attribute 'items'

因此，我认为问题在于检查或将“钥匙”放入该人的物品中。 然后我想检查这个列表，看看战士是否携带它。 如果他是，那么他应该能够打开门。 如果没有，那么门应该保持关闭。 我需要在 TowerRoom 的最后再重复一遍。 在这种情况下，我需要检查最多 3 个不同的项目。 我附上了代码。 希望这个错误是一个非常简单的错误。

我只需要一种方法来使用类“列表”并将东西放入和取出其他类中。 然后，使用该列表中包含的任何内容打开门或杀死怪物。

任何人都可以提供的任何帮助将不胜感激。

Answer 1

您需要创建一个“人”实例（您已经这样做了），而不是使用类：

warrior = Person.new("penne12")

或者使用你创建的

然后你可以使用你的“战士”：

warrior.name #=> "penne12"
warrior.items #=> []

这是因为类本身不存储名称或项目，类的实例（在您执行Person.new时创建）包含项目数组和名称。 试图获取类的属性是行不通的。
