我试图把“陌生人”改为[名词]。在这段代码中：
列出不起眼的物品的规则：什么也不做。
A staircase is a kind of door. A staircase is usually open.
A staircase is seldom openable. The ladder is a staircase.
The ladder is above the Entry and below the Reception.
The description of Entry is "You see ladder forward.".
A stranger man is man in the Reception.
The description of Reception is "You see [the noun] at the reception. On the left side is corridor.".
在描述位置时，我看到“向上”而不是“陌生人”。但是在攻击和remove the noun from play;之后，我看到“没有” - 好吧。
Entry
You see ladder forward.
>up
Reception
You see the up at the reception. On the left side is corridor.
>attack man
You attack the stranger man, causing 5 points of damage!
The stranger man attacks you, causing 7 points of damage!
>attack man

The stranger man attacks you, causing 7 points of damage!
>attack man
You attack the stranger man, causing 6 points of damage!
The stranger man attacks you, causing 2 points of damage!
>attack man
You attack the stranger man, causing 4 points of damage!
The stranger man attacks you, causing 8 points of damage!
>attack man
You attack the stranger man, causing 10 points of damage!
The stranger man die, you win!

You can't see any such thing.
>look
Reception
You see nothing at the reception. On the left side is corridor.
为什么会这样？
答案 0 :(得分：1)
“名词”是一个全局变量，指的是前一个动作的主要对象，在这种情况下是“向上”的方向。当你第二次看时，它会尝试访问前一个对象，但由于解析器失败，结果是空对象，“没有”。
我不太确定你想要做什么，但试图引用那些不会总是在房间描述中那样的人，这几乎肯定是错误的做法。如果你要做的是在退出前列出那个人，那么Emily Short扩展的房间描述控制可能有所帮助。
