In v. Out of Town Effects

[Guardian of Eternity]

Is there any way to have an effect *only* in the outdoors?

I'm talking about Dahak's "dehydration" code (edited by Kelandon). I had never wandered around long enough in my in-progress scenario (unnamed) to notice it, but the damage-factor activated while I was walking around in a town. Ideally, I want to keep this effect only on the outdoor map, not inside of towns.

So, is there a way to do this? Am I just putting it in the wrong place in my scenario script?

Take advantage of the is_outdoor() call, which returns 1 if the party is outdoors and 0 otherwise.
