Reverse engineering player structures in a game [Game Hacking 101]

In order for a game to draw the world, the game process needs to know the location and status of different assets. The game process likely has some central type or class to define what something is within the game world. But how can we find it?

what is th programm?

[@kanutaro3426]

This is the first time I actually understand this concept. I never understood how people turned the reverse engineered structures into actual code, thank you

[@RamesesMendezChamian-xz4dx]

Helps me a lot

[@247CTF]

Great!

[@MrBenderrrr]

These tutorials are absolutely amazing, thank you soooo much for sharing your knowledge Sir ! Do you think in the future or the far future, you could make tutorials on how to implement raw mouse input for games that do not support it? I mean some mods exists for "Nier Automata" and "Dark Souls Prepare to Die" but the source code is not available unfortunately. Making a tutorial or even making this kind of mod in a dedicated serie for a game like Far Cry 3/4 or Splinter Cell Black List would bring a lot of people to the channel as this a feature that has been requested for many years as the negative mouse acceleration makes the game very frustrating to play for many players, and the issues are documented on PcGamingWiki. But anyway, thanks again for all your hard work on your Game Hacking tutorials !

[@247CTF]

Do you have a link to the problem? I don't quite understand what you mean. Some games don't let you use your mouse? Trying to understand the use case/problem.

[@MrBenderrrr]

@@247CTF I'm sorry i didn't explain very well. Some pc games have negative mouse acceleration i which makes playing with a mouse very frustrating and annoying. Some modders have managed to make mods that implement raw mouse input in those games instead, for example this one: community.pcgamingwiki.com/files/file/1221-nier-automata-input-overhaul-mod/ If i understand correctly, they way these mods work is that they managed to hack into the camera transformation function, but i guess it's easier said than done... Other games like, Far Cry 4, still have the negative mouse acceleration issues as making a mod like this require a huge knowledge of game hacking skills. For example the issue about Far Cry 4 is that moving your mouse very slowly will not move the camera view in the game and moving the mouse fast will actually make the camera view move slower. It is "documented" a little bit here in the mouse acceleration section: www.pcgamingwiki.com/wiki/Far_Cry_4

@@MrBenderrrr Argh I see, vectors and 3D space sounds a lot like math to me, so I don't think I will be able to help with this one - good luck!

Would it be possible to upload future videos in higher quality as the text is a little blurry on 1080

[@247CTF]

Yes! I need to record the smaller text (i.e in the debugger) with a larger font size so it scales up better. Will do that moving forward.

[@Cisko1417]

nice tutorial pls make more videos about reverse enginering games

[@247CTF]

Will do!

@@247CTF thx bro ... i like your videos ... i wanna learn more about reverse enginering games

[@Cisko1417]

dissamblers codes games and much more i hope you make a lot videos dedicated from modding games

[@parente1998]

Any tip to start learning the windows.h library? I am cool with asm and c but I know nothing about the windows.h library that you use for injecting the DLL. Any book i should read?

[@247CTF]

Learning it from scratch? No, I don't have a resource I know/can recommend. I Usually go the other way - reverse engineer "something", find another function I don't know, then search on msdn for that function definition to understand it's purpose.

[@pwndepot367]

I know this is years late but if you want to learn the windows api i’d recommend the book “Windows via C/C++”, maybe a little outdated but it will get your foot in the door 👍🏻

[@LowLevelLemmy]

Guys can I be honest? wololololo I love this video 🤗

[@lolsucks3599]

I wanna add new civs to settlers 4 not sure if that is possible but I dont even understand reverse engineering so that is the biggest barrier.

[@247CTF]

Possible.. yes. But it's (likely) more involved than this, you should take a look at 'modding' rather than hacking.

[@gauravthapa4380]

What about Online server games can it be hacked ??

[@247CTF]

Depends, maybe. Any modern game will most likely have protections for these kinds of silly tricks. These topics and videos aren't for modern online games.

Could you help me out pls?? I am trying to crack a simple software that i almost got access but since the account is lost on the software i can't use any function from the software.. it's a expensive rare software and i manage to get the files but need to get reversed in order to use it

If you lost your account information, you should contact the vendor. No illegal shenanigans here.
