Understanding the listen skill

As an additional info, I've tested the area's listen modifier with a few values, and upon giving a negative one(-10), poof! I'm instantly heard by the creatures. I'm not sure this is a clean approach though...

hmm strange, I had negative results with this, nothing had changed

Try this script, I guess the listen DC and maybe also listen rank still needs to be corrected but its a start:

EDIT: both scripts improved

well of course, they dont have to, if you remove the heartbeat code, they still will be able to perform attacks, however they SHOULD HAVE. Without it, they wont wander around area, they wont do any special behavior etc. Default AI scripts contain heartbeat and its fine.

Since the code performs only single line when there is no player in area, there is minimal CPU intense. I was also very obsessed with script performancy, but then I learned how AI works. Believe me, each attack against single creature creates huge ammount of scripts run and code being performed. Even worse with area of effect spells like fireball. Each hit by the spell cause each creature to perform attack and tell every other creatures nearby to do the same. With default AI scripts if you get hoarded by 50+ small monsters and you cast aoe spell like meteor swarm, you will see a huge lag. (if you are interested in this issue, I have some tips how to prevent it, unfortunately no idea how to fix it)

SO being concerned with something so simple as heartbeat is really senseless. Though its a good idea to somehow despawn or clean your monsters if you are working on PW, in single player module neither this have any sense.
