muddle up the code and change the way he wrote it, so lets say it is made up in livecode:
line 1: ask "enter fov"
line 2: put it into fov (-- fov is a veritable)
and then u can change it to:
line 1: ask "dont put in an fov"
line 2: store it into fov
as an overall u prob dont understand the language livecode, but as a overall answer just muddle the code up and try and change the way it has been writen, because an anticheat is kind of like a plagurism checker as they check if they have seen the code before if so then ban it.
bit confusing but hope it helped answer back telling me if u want a better explanation
