我正在制作一个 python 文本冒险游戏。需要帮助制作“库存”；

Question

我正在做一个 python 文本冒险。它基于《艰难学习 Python》中的 ex41，因此有些相似。然而，我的问题与该练习无关。我正在尝试创建一个库存，以便可以拾取和使用某个物品（即钥匙或风风）。

起初我的计划是使用一个布尔变量，这样当该项目被“拾取”时，它会将一个值设置为 True，但它似乎不起作用。我认为问题在于，一旦我离开房间，该值就会重置。

现在我正在尝试一个列表，当“拾取”该项目时，该项目将被附加到库存列表中。

我怎样才能清点库存，或者至少“拿起”一个物品，然后“使用”它？

我认为重要的代码行是 18-20（在 def __init__(self, start) 下）、77 行（在 def cell(self) 下） >), 161-162（在 def janitor(self) 下）。

Answer 1

您的方法似乎工作正常，但有一些错误。在 cell() 中，您需要在 elif "febreeze"... 语句之后（在注释开始之前）添加 :。此外，在 elif 块的末尾，您需要返回“cell”。通过这些更改，我可以拿起 Febreeze 并使用它。

Answer 2

如果您将库存定义为列表（这就是我所做的），那么您可以执行以下操作：

    class Attributes:
        def __init__(self, inventory):
            self.inventory = inventory

    Player = Attributes([])
    Player.inventory.append("Febreeze")

方括号创建库存，“追加”将 Febreeze 添加到其中。

Answer 3

如果你试图将它定义为一个列表，例如（猜测这是在Python上）

def inventory[]
    inventory.append
add item (inventory)

不记得如何将它添加到库存中，但有一些基础知识
