i made something similar to this but same idea
i used a numeric menu item to control it so it would be like
"shity ghost" = num
replacing num with 10 , 20 , 30, 40, 50, 60 and so on... i also had the negatives in there so you go glitch down and get under the map to not have to go so far
maybe i will release it and my hack soon.
i just moved from my old base to a new one so i havent added it yet but i will
EDIT:
actually i just noticed its in my signature
||
\ / there
its the "VirJump(-/+ 100)"
EDIT #2:ill add a pic of my new menu in a bit
