What function returns the players position?

Conceivably you could cover the whole map in a tight grid of SA's and track them like that, but it won't be very fun to arrange

Well you could just do it in the local area where you wan't the event to take place. I could be worth considering, but it will be a challange. =P

That's totally true, and would reduce the levels of pain-in-the-arsedness you'd have to deal with, but you may as well just use a few well placed SA's. I doubt the trouble would be worth it in the end
