Interested Into Getting Into Hack Creation! Need Some Help!

The best language to use for cheating is C++. However if you're not confident enough, feel free to use c# or something else, as long as the language can rewrite memory. What you're looking for is externally use ReadProcessMemory/WriteProcessMemory. Take a look at the ProcMem class to easly rewrite memory (this isn't needed). Search a small source code (bhop, triggerbot..) and see how the memory hacking actually works. In the beginning it might be annoying and hard, but when you get how it works, it's easy.

Also, don't give a fuck about VAC. If you know how a simple hack works but you write it on your own way and don't publish it, you're fine, lol.
I state this because VAC uses signature scanning. I'll let you do the research on what that includes.

Feel free to ask more questions.

Hey, i'm also thinking about creating my own cheats but i do not know where to start. I do not know any ''language'' yet but which one should i start with to come to c++? Or is it just that i can jump to c++ immediatly without knowing html,java or something?

I was learning html, css and php. Then i realised that it's boring as fuck and moved to c#. So yeah, you can start at c++. However, take a look at c#, it's really easy and you can obviously rewrite memory in that language aswell.
