 Posted: Tue Jan 08, 2013 10:27 pm Post subject: Having trouble using pointer scan :( |
 |
|
So I was able to use pointerScan to great affect on my own XYZ in a game i'm currently relearning hacking on (gave up a couple years ago due to RL issues).
However, trying to find the identities list for all objects in my area has got me stumped.
Attempts 1-14 = searching for my alt account's Y-coord has yielded me with nil results. Each time I found TWO addresses, either with 4-byte searches or float. Both times each address, when frozen, would affect my alt account's Y-coord differently. One would gently keep her floating, and the other would jaggedly bounce her up and down when frozen.
Pointer Scanning both of them several times in a row always comes back with 0 process results on the 2nd or 3rd scan (normally the 2nd).
HOWEVER, when freezing and changing the value for EITHER address that I found it would change her Y-coordinate accordingly for my Main's screen.
What's going on here? I also tried manually tracing back but always ran into a deadend with nothing accessesing or writing to my 2nd or 3rd depth pointer (which is why I assume pointer scanning constantly comes up with 0).
Any ideas as to how I can proceed past this point? I've also tried searching for local name's using Memory View in CE, and nothing really ever comes of that looking 4bytes in steps up/down from that address.
Cheers 
ps: My goal is to create an "external" Radar that only READS enemy positions from the game, and never directly hooks in at all in any way to remain relatively undetected. (inspired by a ModernWarfare hack someone did back in 2010)

Perhaps the structure starts with a specific vtable pointer that you can do a memoryscan for

Any advice on how I can go about searching for said vtable pointer ?
Is there a search method I can go about locating it with? I'm unfamiliar with finding them  .

Most object oriented programming languages store as first entry of a class object a pointer to the class definition.
Objects of the same class have the same pointer to that class, and most of the times (JIT languages excluded) the class definition is defined in static memory (green)
So if you can find the base address of the structure (or just look for a vtable manually) you'll find a pointer to a static address.

Right, but the issue at the moment is that I cannot find the base address of the structure that handles objects around my character.
I did a dissect of my player's struct which contains my XYZ, runspeed, name, etc and it is a different class all together.
Apparently, from what I'm seeing, the class that handles objects around me (banks, chests, mobs, players) are the same thing. So i've been trying to just find that base address for ONE item. However, due to my inexperience with manually going through memory and searching for stuff like that to identify classes & structs I believe I'm probably the issue  .
I'll keep punching away at it.
Do you know any tutorials that may be of help for finding the identity struct that would hold multiple objects? Something that MMORPG's might use? I found one for AION, however it was only a C++ programming tutorial, and wasn't for actually finding said struct using CE or any memory editor persay.
Thanks !
ps: My next attempt will be based on HP. I'll do a "Float" "Unknown init value" search, and then do "decreased/increased/unchanged" based on my Alt's HP.
Hopefully I'll be able to track down her HP, and then follow the pointers back to her base struct to find the identity struc.
