Inform7:处理房间的属性

Question

我对这门语言非常非常陌生，把我的注意力集中在“如何用东西做事”上，这证明是一项非常令人沮丧的努力。

我在这里的目标是创造一个技工，在那里某些房间是危险的，并变得更危险的球员停留在他们的时间。如果玩家在危险的房间里呆得太久，就会触发死亡场景。

我有这样的代码：

[The "danger rule"]
A room has a number called danger level. The danger level of a room is usually 0.

Definition: A room is dangerous if its danger level is 1 or more.
Definition: A room is deadly if its danger level is 9 or more.

Every turn (this is the increasing danger rule):
    If the player is in a dangerous room:
        Increase danger level by 1.

Every turn (this is the death by danger rule):
    If the room is deadly:
        do nothing.[Later...]

Every turn (this is the danger explanation rule):
    say danger level.

[further down]

The Feeding Chamber is south of the dungeon."You enter a large, dimly lit room with straw on the floor, surrounded by various cages embedded in the wall.[line break]Blood spatters are all over the floor, and it looks as if there's been a fight recently". After going to the feeding chamber for the first time:
    try looking;
    say "It smells like grues around here. I would be careful if I were you..";

The Feeding Chamber has danger level 5.

我似乎想不出如何正确地处理“房间的危险程度”。我定义的解释规则在进入危险的房间时会导致运行时错误：

`*** Run-time problem P31: Attempt to use a property of the 'nothing' non-object: property danger level`

..And试图将规则重新定义为类似于the danger level of the room或the danger level of this room之类的内容，这会导致令人费解的编译消息，例如：

`In the sentence 'say the danger level of the room'  , it looks as if you intend 'danger level of the room' to be a property, but 'a room' is not specific enough about who or what the owner is.`

以这种方式引用对象属性的“正确”方法是什么？

Answer 1

这里的神奇词是"of the location“。如果我们暂时假装这是另一种编程语言，那么我编写它的方式就好像是指类"the room“，而不是指当前被引用的"the location”类的实例。

工作规则如下：

Every turn while the player is in a dangerous room:
        Increase danger level of the location by 1.

诀窍是给出足够的信息来知道你指的是哪一件事情。原来的问题句是完全有效的英语，人类可以解析，但计算机需要更多的帮助，以确定我们指的是什么房间，当我们说“房间”。
