我对 Inform 很陌生，看起来这不应该太难做，但我还没有找到方法。我想根据玩家的来源更改房间的描述。类似于以下内容：
The Town Square is a room. "As you enter the small town square, [if yourself came from West]
the rising sun makes silhouettes of the roofs and spires to the East.[otherwise]your long
shadow strides before you as the Sun rises behind.[end if]"
解决这个问题的最佳方法是什么？
我找到了一个合理的解决方案：
The last location is a room that varies.
Orientation is a direction that varies.
Before going to anywhere, now the last location is the location of the player.
After going to anywhere:
now orientation is the best route from the last location to the location, using even locked doors;
continue the action.
The Town Square is a room. "As you enter the small town square, [if orientation is east]
the rising Sun makes silhouettes of the roofs and spires to the East.[otherwise if orientation is west]
your long shadow strides before you as the Sun rises behind.[end if]"
“使用偶数上锁的门”修饰符确保即使门在玩家身后关闭并锁上也能正常工作。该解决方案确实假设玩家是通过可逆路线来的，但情况可能并非总是如此，例如玩家已经传送。
