Portable way to get classmanager - UC-Tutorials - Multiplayer Game Hacking and Cheat Tutorials

I don't like static offsets and with patches coming for BF2 and BF2142 I have been looking at my code to see how I can head off any work they may create. With my ClassManager offset being hardcoded I decided to make this little function to get a pointer to the ClassManager from RendDX9.dll.

Tested on BF2 1.41 and BF2142 v1.50 and BFH

Put this in header file

Code:

// Tested on BF2(1.41) and BF2142(1.50)
#define PATT_CLASSMANAGER "\x89\x35\x99\x99\x99\x99\xFF\x15\x99\x99\x99\x99\x8B\x0D\x99\x99\x99\x99\x8B\x01"
#define MASK_CLASSMANAGER "xx????xx????xx????xx"

CClassManager* getBFClassManager(void);

Code:

CClassManager* getBFClassManager(void)
{

    HMODULE hModule = NULL;

    while (hModule==NULL)
    {
        hModule = GetModuleHandle("RendDx9.dll");
        if (hModule == NULL) Sleep(200);
    }

    DWORD dwInitDLL = (DWORD)GetProcAddress(hModule, "initDll");
    CloseHandle(hModule);

    if (dwInitDLL)
    {
        DWORD dwPointerOffset = FindPattern(dwInitDLL, dwInitDLL + 512, (BYTE*)PATT_CLASSMANAGER, MASK_CLASSMANAGER);
        if (dwPointerOffset)
        {
            DWORD* ptr = (DWORD*)(dwPointerOffset + 2);
            return *((CClassManager**)((DWORD)*ptr));
        }
    }

    return 0;

}

You will need Strife's FindPattern function, scroll to end and get the updated version.
