[Request] Modify Visibility hack

vrubayka opened this issue 2 years ago · 9 comments

Hello!

Great trainer.
Is there a way to modify your code to force the highest visibility instead of the lowest? I wanted to play around with the AI.

I imagine it should be done in src/hacks.c under hack_GodMode but it's all greek to me.

void hack_GhostMode(bool bEnabled)
{
    char* const visibility_op = (char *)(module_base_addr + offsets_invisibility_base);
    char* const visibility_original = "\x8B\x86\x18\x15\x00\x00";  // mov eax, dword ptr [esi + 0x1518]
    char* const visibility_patch    = "\x90\x90\x90\x90\x90\x90";  // nop
    size_t visibility_size = 6;

    char* const noise_op = (char *)(module_base_addr + offsets_noise_base);
    char* const noise_original = "\x3B\xF8";  // cmp edi, eax
    char* const noise_patch    = "\x39\xC0";  // cmp eax, eax
    size_t noise_size = 2;

    // Add third op for slider

    if (bEnabled)
    {
        memory_patch(visibility_op, visibility_patch, visibility_size);
        memory_patch(noise_op, noise_patch, noise_size);
    }
    else
    {
        memory_patch(visibility_op, visibility_original, visibility_size);
        memory_patch(noise_op, noise_original, noise_size);
    }

}

is the function that would be responsible for this!

You would probably end up changing:

    char* const visibility_original = "\x8B\x86\x18\x15\x00\x00";  // mov eax, dword ptr [esi + 0x1518]
    char* const visibility_patch    = "\x90\x90\x90\x90\x90\x90";  // nop

to something like:

    char* const visibility_original = "\x8B\x86\x18\x15\x00\x00";  // mov eax, dword ptr [esi + 0x1518]
    char* const visibility_patch    = "\xB8\xFF\xFF\xFF\x7F\x90";  // mov eax, 0x7FFFFFFF
                                                                   // nop

and then recompiling the code

I'm using a Debian 11 VM and I have installed i686-w64-mingw32-gcc and I had to install nasm because I was getting an error about its absence.

Answer 4 · 2023-04-16T17:13:44.000Z

Yeah, that code is spaghetti. Some of my first C code. I'll make a fix for it today

Answer 5 · 2023-04-16T17:52:37.000Z

Code fixed, it should compile now. I'll be making modifications for this thing to use Docker like my more recent projects to handle dependencies/tools.

Answer 6 · 2024-02-16T18:32:12.000Z

Hi again, I decided to try you trainer again, I see you've done everything in assambly now.

Would you mind sharing ASM code that would make player character 100% visible at all times?

Answer 7 · 2024-02-25T01:55:12.000Z

yeah let me see if I can write that

Answer 8 · 2024-02-25T02:25:54.000Z

I see that you can change

mov eax, [esi+0x1518]

to something like

mov eax, 0x1
``` 0x1 and it makes you visible with the slightest light source
