I have seen all bases use that one, it was a suggestion/question.
You obviously never took the initiative to learn the basics of Programming.
A "Sleep" is basically a delay.
It allows you to delay your next instruction in your program by miliseconds.
Sleep(100) = 1 second
Sleep(222) = 2.22 seconds.
So, in a while loop.
A sleep will help reduce lag, and also allow you to offset the time of when the next instruction gets called.
A sleep longer sleep is better in this case.
No I do not make game hacks anymore, please stop asking.
