what is this....

what is antiAFK???

and how to code it???

I think when you're in a game and you're inactive for too long you get kicked but with AntiAFK you wont get kicked if you're inactive for too long. Forgot how to code it

Quite simple... AntiAFK as the address' value itself is a counter how long do you have been idle (inactive). When the counter reaches a specific value the Game disconnect. You just have to set the value equal zero so that it seems like you are active all the time.
