Decompiled gObjCreatePet function from main.exe (1.03.15) eng

Kiosani · Oct 10, 2014

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!

Code:

[COLOR=#ff0000].cpp file[/COLOR]

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);
}

Code:

[COLOR=#ff0000].h file

[/COLOR]#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;
// --

Video test:

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 · Dec 13, 2015

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

you should make it work like panda pet and not guardian

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

    int ItemSwitch = *(WORD*)ItemId;
    int PetPreview = LODWORD(pPreviewPetThis) + 700;

    switch(ItemSwitch)

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,

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

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).

beyond gObjCreatePet you do something more for the image of the pets appear on the doll?

yes, I have decompiled: 20% from main code to make this

gObjCreatePet is only to make a Temp view from every Pet on Viewport using.. Item inventory id.. I say on the first post, that to make a complete work with this is necesary decompile: gObjMakePreviewCharSet function from your main.exe and anothers like: Pet Follow Character, Pet HP Bar Interface, Pet Walk on the Map (for: Fenrir Style Pets), and etc.

I could not make it work in the main 1.05D, the pets are static, are not walking around the character ... thank you.

You need to create a function to follow the player, i mean make a function to pet work.
