Using an attribute in place of the percentage for a stochastic rule

Question

I was wondering whether there was a way of allowing the use of an named attribute, say "parking_occupancy" in the stochastic rule.

Instead of :

20% : placecar
else: NIL

I could use (I know this doesn't work, but you get the idea)

attr parking_occupancy = 25

parking_occupancy% : placecar
else : NIL

This would mean I could adjust the variable in the inspector and not the rule file... am I missing something obvious? Is there a workaround?

Haha... If you weren't able to, you'd still have some time left to learn until you have to teach it to your youngest .. 😉
