Demon Pet Show: "Life" Text insted of: "Durability: %d" Client Source 1.03K

[Kiosani]

Hi for all, first I like to say.. that I'm decompiling Inventory class from my main.exe and I found this small code on my research.. (is only assembler inline), but works, this is to change: "Durability: %d" (on my: Text.bmd from 1.03K JPN Client is line: 71 number) by: "Life: %d" text (70 number line), this is for: Pets job, maybe to some person can be usefull, enjoy it.

Pet.h file:

#ifndef _PET_H
#define _PET_H

#define ItemId(x, y) ((x * 512) + y)

void DemonShowLife();
void ItemSpecialToolTipHook();


#endif

Pet.cpp file:

//Buffers:
DWORD AddLifeText_Offset = 0x00595F77;
DWORD ReturnLifeText_Offset = 0x00595F94;

//Inline Function (Re-writed):
void __declspec(naked) DemonShowLife()
{
    _asm
    {
        CMP AX, ItemId(13,64)
        JNZ DarkWolf_Label
        JE AddLifeText
        // ----
        DarkWolf_Label:
        // ----
        CMP AX, ItemId(13,97)
        JNZ Unicorn_Label
        JE AddLifeText
        // ----
        Unicorn_Label:
        // ----
        CMP AX, ItemId(13,106)
        JNZ Rudolf_Label
        JE AddLifeText
        // ----
        Rudolf_Label:
        // ----
        CMP AX, ItemId(13,67)
        JNZ Panda_Label
        JE AddLifeText
        // ----
        Panda_Label:
        // ----
        CMP AX, ItemId(13,80)
        JNZ Dragon_Label
        JE AddLifeText
        // ----
        Dragon_Label:
        // ----
        CMP AX, ItemId(13,110)
        JNZ Skeleton_Label
        JE AddLifeText
        // ----
        Skeleton_Label:
        // ----
        CMP AX, ItemId(13,123)
        JNZ ReturnTextLife
        JE AddLifeText
        // ----
        AddLifeText:
        // ----
        JMP AddLifeText_Offset
        // ----
        ReturnTextLife:
        // ----
        JMP ReturnLifeText_Offset
    }
}

//Hook Function:
void ItemSpecialToolTipHook()
{
   Utils.SetRange((LPVOID)0x00595F8E, 6, ASM::NOP);
    Utils.SetJmp((LPVOID)0x00595F8E, DemonShowLife);
}

PS: BUGS = 0 (Here I don't modify nothing from original main.exe intermal memory, I mean: EAX, ECX, EDX registers and etc.)

Another way to make this is combining: ASM + C++ (Boolean Function).. but on this way is necesary change: AX to: EAX on: _asm block..
this works too.. (but on this way is possible have: bugs):

BOOL bShowLifeText;
DWORD dwShowLifeText;
DWORD dwShowLifeText_Buffer = 0x00595F94;
DWORD ShowLifeText_Jump = 0x0059614D;

void __declspec(naked) DemonShowLife()
{
    bShowLifeText = FALSE; //This is important, because you don't like that another items like: Helm or Armor change: Durability Text by: Life :D
    // ----
    _asm
    {
        MOV dwShowLifeText, EAX //Here is necesary change: AX by: EAX instruction.
    }
    // ----
    if (dwShowLifeText == ItemId(13, 64))
    {
        bShowLifeText = TRUE;
    }
    else if (dwShowLifeText == ItemId(13, 97))
    {
        bShowLifeText = TRUE;
    }
    else if (dwShowLifeText == ItemId(13, 67))
    {
        bShowLifeText = TRUE;
    }
    else if (dwShowLifeText == ItemId(13, 106))
    {
        bShowLifeText = TRUE;
    }
    else if (dwShowLifeText == ItemId(13, 80))
    {
        bShowLifeText = TRUE;
    }
    else if (dwShowLifeText == ItemId(13, 110))
    {
        bShowLifeText = TRUE;
    }
    else if (dwShowLifeText == ItemId(13, 123))
    {
        bShowLifeText = TRUE;
    }
    // ----
    if (bShowLifeText == TRUE)
    {
        _asm
        {
            XOR ECX, ECX
            MOV CL, BYTE PTR DS:[ESI+0x16]
            PUSH ECX
            PUSH 0x46
            JMP ShowLifeText_Jump
        } //Here I re-write the complete Assembler part of code to: "Set" -> Text.bmd number line: 70 -> (In hexadecimal: 0x46)
    }
    else
    {
        _asm
        {
            JMP dwShowLifeText_Buffer //Here I make directly JUMP to: Offset stored on: DWORD Buffer, because is not necesary: MOV instruction first.
        }
    }
}

HOOK Function is the same:

Utils.SetRange((LPVOID)0x00595F8E, 6, ASM::NOP);
Utils.SetJmp((LPVOID)0x00595F8E, DemonShowLife);

If some person is interested on learn something more from: ASM with C++, on this page you can understand a very usefull concept to:

"Jumping from ASM block to C or C++ Label (Out) and from: C or C++ Label to: ASM Label"

Do this just because text.bmd is incorrect and show me Durability instead of Life: ??

And thanks for using my main :D

Nope. Is just.. custom. Isnt bug, isnt error..

Is only a custom, yeah.. but wz on main.exe 1.03K JPN source code.. forgot it to include: "Rudolf Pet" & "Panda Pet", to this small function. then is a fix too.
