I've got a travelling salesman NPC in my mod. He wanders from town to town on a schedule, buying and selling from the town squares of different cities on different days.

What I want to do is give the player a spell or an item or a scroll perhaps that, when activated, points the arrow on the map to the NPC in question.

a) can it be done?
B) how do I do it?

I've been looking through tutorials and scripting commands for the past two hours. I'm relatively new to scripting, but intermediate at the CS.

And since I'm here. Maybe you guys can help me get the guy to ride his horse from town to town instead of walking/running. I created a horse, set the ownership to the salesmen NPC, but when the trigger came for him to move on to the next town, he just ignored the "Use Horse" setting and walked all the way. What did I do wrong?

Thirdly, I want my NPC to put his hood on when it's raining and take it off when it's not. How do I do that?

Your help is greatly appreciated. I'll keep searching in the mean time.
