    WoW 3D model bone transformation matrix

    Allright, for my ESP hack i want to replace my stupid rectangles with bones, and i know how to do that.



    In a bone transformation matrix, each bone has its own xyz rotation, xyz coordinates ect. In WoW, i am not able to find such matrix. I kept scanning with CE for 40 minutes. It's simple.. i fly to the sky and i scan for increased value. Then i fly back to ground and scan decreased value. So i should have been able to find the Y position of all bones. But WoW doesn't store them like that i guess.. i found nothing. Any help ? I found region in memory that contains all bone rotations with values from -1 to 1 (weird), and i know they are related to the bones because when i go to sleep with my druid in bear mode, the rear legs of the bear are not animated. And the values don't move. But NO X Y Z coordinates are near those values.. really really weird.

    EDIT: It's normal i guess... the game uses the same game engine from 2004. And i guess the game works like this to save performance.
    First, i was annoyed by it's stupid 3x3 matrix. Where the hell you can see a 3D game that uses 3x3 view matrix?? And now i can't find the retarded bones.

    I mean WoW is known for its stupid/nonsense spaghetti code, so doesn't surprise me at all.

    Why not look over CM2Model::GetBonePosition?

    I am always external, so i wont be able to call it. Instead i would try to find out how it works and re-create it externally. Can you please provide me with signature for this function? I dont have its location in memory in 3.3.5(not retail)

    Quick look, this could be GetAttachmentPosition, and GetNamePosition should point you in the right direction.

    Code:
    //3.3.5 12340
    CM2Model::GetAttachmentPosition = 0x831330,
    CM2Model::HasAttachmentPosition = 0x8273D0,
    CGObject_C::GetNamePosition = 0x7451B0,

    I see now... the bones are stored as "local position" (inside the gameobject). Kinda just like in Unity 3D. Bones use local position, not world position like in the FPS game in my video. Gosh, i pray i can make something out of this cr@p.

    EDIT sorry forgot to say thanks for the help )
