When can I move on?

Look into working with classes, pointers, memory management, containers etc. as well to make sure you understand how they work. You should also debug your own applications and see how the obtains are handled low-level to understand how to locate things in a games memory.

As Bora mentioned too, start looking into the system API too and get yourself familiar with working with them too.

I know this sounds kind of newbie, but what is the hardest thing about hacking? Is hacking harder than actually creating a game yourself? Do you need mathematics to hack? Is it hardest to find the memory adress of what oyu want to hack in a game?

What I really wanna know, is if you benefit in knowledge when making hacks. Could it be a starting point of making games since you work with memory and so on.

EDIT:

It's just that a lot of people says stuff like: "YOU DON'T LEARN BY HACKING! IT'S NO EXCUSE!" and so on...

1.It depends on what you think is hard
2.Hacking is much easier than creating a game this is because you are essentially just making an add-on to the game when you hack it.
3.Maths is required if you want to make aimbots but other than that you only use basic maths.
4.Finding memory addresses is one of the easiest things you can do.
And finally ... 5.You do benefit in knowledge by hacking. this is because you learn how programs are structured and you will also learn how to computer actually works.

The hardest thing about hacking is the reverse engineering probably. Not to say that it is hard, but for someone just starting, it will have its challenges. Especially if you do not understand ASM at all.

As for is it harder than creating a game, that depends on how you go about creating your game. Using a bunch of different pre-made libs and/or engine(s) can make creating a game extremely easy. In most cases though, creating the game will be harder than hacking it though.

Mathamatics are needed for calculations on things such as:
- Aimbots
- No recoil (depends on the game)
- Encryption

And so on. So it does help to understand what you are doing mathematically too.

Yes, you gain knowledge and understanding of a games inner workings as you hack it. Which can help produce more hacks for other games etc in the future. If someone tells you it's not something to learn from they probably have no idea what they are doing themselves.
