EDIT: This is not a tutorial lol I am asking a question. It only sounds like a tutorial at first because I feel it's important to explain myself so it's easier to get help.

I managed to find packet structures in one game so far.

For example, if you were to attach WPE to this game and record a movement packet you would get this "18 00 E3 XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX". Ok, obviously 18 is the packet size, right? and E3 is the game function the packet is sending, so E3 = the command that tells the server to move. E3 can be changed to anything, for example an attack packet would be F9 in place of E3. Get it? Ok now that I explained a bit about the packet structure in this game I'm going to explain something else.

Here's what I find interesting.

Below is the E3 command of the packet in the memory and it shows as 79E. If you were to do an assembly scan for this packet function it would look like this below:

ecx,0000079E (I don't remember exactly if it was E3, this is just an example)

Now just a few addresses below that you will notice another address that shows this, the packet SIZE:

ecx,00000012

Now the packet size is 12 in Hex, which would make the packet byte size 18 if you recorded a movement packet with WPE. If I change the packet size to 13 in the memory then that would make the games movement packets 19 bytes long.

Awesome isn't it? I've pulled off miracles in one game by manipulating packets via cheat engine.

However, if I were to do an assembly scan on the size of a packet in a different game, like 0000002A for example, would I possibly pull up accurate results to a particular packet I am searching for? (I search for packets by their size, I don't know why)

Do all games show packet structures in the memory the same way as this game?

Like the example I showed above.

So in this particular game I'm able to modify packets through the memory and it works great making mods.

And please, if you have any nice and quick methods for finding packet structures in the game, then PLEASE share that with me. I'm familiar with most of cheat engines features so I hope I'm not a pain in the neck

Thank you guys! I apologize for my lack of knowledge and terminology but I'd like to think I'm not bad with cheat engine for all the things I've pulled off in games xD

Happy hacking.

You can also set a breakpoint with ce and log/modify things

It starts with a basic windows api, but you can adjust if to the winsock api
