[
]: In this post I want to demonstrate my system “ANTI DEX” which detects almost all instances added by exploit.
[
]: This system is intended both for novice developers and for those who want to improve their anti-cheat; This system may become inoperative at any time, I do not guarantee that it will detect all exploits and cheats!
Let’s start with the fact that there are many scripts that were made so clumsily by their developers that it gives almost all developers access to create their own system to detect an element added to the game from nowhere. So why not spend a little time creating a simple detector that will scare uninvited guests who like to play with their injector scripts that are not protected from easy detection?
So, in this post I want to share with you to say that this system detects any addition of something to the game that does not exist either on the server or on the client. (anti saveinstance() too).
[
]: And I also made sure that this system did not load the memory of the players and the server itself:
Server script:
Local script:
Here are the scripts themselves:

result = result .. characters:sub(randomIndex, randomIndex)
