Speedwalk character to regular direction
|
Problem: I need to obtain roomnums, which I can go to from current room. Easily i created this code:
| Code: |
#FO %roomexit() {
#sh %i - %roomlink(,%i)
} |
But it doesn't work, because roomexit() returns something like "w|k|e|l" and roomlink() needs dirs like w|se|e|sw.
So how do I convert it? |

#FO $roomexit() {
$this=%reversedir(%reversedir(%i))
#PRINT {$this - %roomlink(, $this)}
} |

Nope, double reverse doesn't work in this case (i.e. converting single speedwalk char to direction).

The way to do this is to either %replace() the single-letter directions with the correct two-letter direction, or use #SWITCH to essentially do the same thing. There is no easy conversion from single-letter path direction to proper direction name or abbreviation
