So you see, alot of people have been hacking, especially in bootcamps. Alot of people have been giving me the source of the hacks, and it is cheat engine. If it is possible to code, can you make it, that if cheat engine is in opened in the backround, then they are banned until it is closed?

thats not fair! I use it for storing micemon and thats not hacking! it would be unfair for me and my friends to get banned until we stop playing with micemon :(

There is the anti-cheat and it was updated not long ago if I am right

The game already has an anti-cheat engine.

Alot isn't a word.

The server already senses that CheatEngine is on a PC and bans you.
The hacks that are used the most involve standalones or quickly made browsers using KHTML or Mozilla webkits from my understanding. You can't block those because then nobody will be able to play.

Based on what has been said above, I am assuming there is anti-cheat protection in place. However, where one window is shut, someone will always try and open another. Or make a hole in the wall. Whatever their style is. There are ways of bypassing anti-cheat programs. While they usually aren't simple, if someone wants to get past them, they'll do it.
