Inform7：根据玩家的来源更改房间的描述

Question

我是 Inform 的新手，看起来这应该不难做到，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。大致如下：

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]"

解决此问题的最佳方法是什么？

Answer 1

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]"

"using even locked doors" 修改器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，例如如果玩家已经传送。
