Vac Distance?

I'm still pretty new to this whole hacking thing, so I have a question that's probably really simple, but I can't seem to find the answer. I'm very cautious about hacking in public, so here's my plan.

I'm lvl 54, but I'm in Python Castle. I was planning on vac'ing Styx, which I have already done. However, I have a wall hack on Python, and I would like to be able to go to an edge of the map, or at least somewhere where people won't see me, so that I can vac without being seen. What is the parameters that I need to edit to make them vac to me from such a major distance, or is it not possible to vac that far away??

-this is a part of my mob info section .. i can pretty much vac a mob that goes visible on my screen...

that was what I was trying to figure out. If I could vac them before they became visible...lol...I don't think that's possible though... =[

well if thats possible why do you have to move arround?... just be happy on what you have now...
