Decompiled gObjCreatePet function from main.exe (1.03.15) eng

[Kiosani]

Well hello everyone again this time I would like to share my decompilation of this function that basically what it does is create a starting object an item equipped in the Character's Inventory, Enjoy it!

.cpp file

ObjCreateBug gObjCreateBug		= (ObjCreateBug)0x004ADF24;
ObjCreatePet gObjCreatePet		= (ObjCreatePet)0x0075720C;

void gObjCreatePetEx(int ItemId)
{
    int ItemSwitch        = *(WORD*)ItemId;
    int PetPreview        = LODWORD(pPreviewPetThis) + 700;
    // ----
    switch (ItemSwitch)
    {
        case ItemId(13, 98):
            gObjCreateBug(eBugType::Skeleton, PetPreview + 252, PetPreview, 0, 0);
        break;
        // ---
        case ItemId(13, 99):
            gObjCreateBug(eBugType::Unicorn, PetPreview + 252, PetPreview, 0, 0);
        break;
    }
    gObjCreatePet(ItemId);
}

void gObjCreatePetExHook()
{
    Utils.SetHook((LPVOID)gObjCreatePetEx,(LPVOID)0x0073684D,ASM::CALL);
    Utils.SetHook((LPVOID)gObjCreatePetEx,(LPVOID)0x0075567E,ASM::CALL);
}

.h file

#define ItemId(x, y)            ((x * 512) + y)
#define pPreviewPetThis            *(DWORD*)0x07A76A00
#define LODWORD(h)                ((DWORD)(__int64(h) & __int64(0xffffffff)))

enum eBugType
{
    Skeleton        = 7587,
    Unicorn            = 7588,
};

typedef void (__thiscall *ObjCreatePet)(int ItemId);
extern ObjCreatePet gObjCreatePet;
// --
typedef int (__cdecl *ObjCreateBug)(int BugId, int Arg2, int Arg3, int Arg4, int Arg5);
extern ObjCreateBug gObjCreateBug;
// --

PS: This is my own code based on original...
I mean.. is not complete decompilation code of original function from main.exe code, but works to add new pets.

PS 2: This code is only to create a temporal preview of every pet or object equipped (for a complete work with this you must modify your server side & client side gObjMakePreviewCharSet functions)... to generate movement on every model, hp bar for pet and etc, you must use anothers functions from your main.

You could post the main? or to offset 1:03:11?

[SmileYzn]

Wooow thanks, i already using this in my s4 project anyway. Man really thanks

[ftewegw1]

wrong animation
you should make it work like panda pet and not guardian

You could pass the main 1:03:15 clean?

You could pass the main 1:03:15 clean?

I uses 1.03.11, sorry.

Excuse the question, but where I can find enum eBugType
{
     Skeleton_Pet = 7598,
     Unicorn_Pet = 7599,
};

I saw that the .15 is different numbers could give a short explanation? thank you!

Is only the ObjectId bro... -.-!

Small Explain:

ItemId calc = Type * MaxIndex + Index
ObjectId calc = Type * MaxIndex + Index + ItemOffsetInArray(834)

Then... for:

case ItemId(13,106):
{
gObjCreateBug(eBugType::Unicorn_Pet, PetPreview + 252, PetPreview, 0, 0);
break;
}

because is -> ObjectId calc: 13 * 512 + 106 + 834 = Unicorn_Pet = 7596,

#define pPreviewPetThis *(DWORD*)0x07A76A00

You could post the 1:03:11(jpn)?

I don't remember (I think that is this: 0x7A723B8)

[NaveMu]

brow a question, after I put in my source that I need to do that to give + "load" in their image on the client?
mine is named "IMP" and the image of IMP ..

[Kiosani]

I'm working (for fun purposses & maybe sell too ^^) on this the lastest days on this:



PS: I'm decompiling so much functions from my main.exe to make this hmm.. is COOL guys ?
PS 2: Actually.. I can add any Pet Type.. (I have decompiled Pet Class from main, maybe create a cool System like: Muun xD).
