[Trigger] The further away, the more damage - how?

[Csicska]

I'm looking for a trigger that deals damage to units around a boss depending on how far away they are standing from this certain boss. My problem is that I can't find one. Could anyone help me out please?

Thanks, that would be nice, but sadly I know nothing about JASS

EDIT: Ok, I've just realised that while I don't know too much about this JASS thingy, I still speak english, so I read what was written there and found "Distance between two points", just what I was looking for. Thanks again
