somethings wrong with the patternScan func or the Pointer.

[Leoonv2]

i tried to find out why my program does not hook. in the dllmain.cpp it prints Hey! but does not continue going through code after

std::cout << "Hey!" << std::endl;

auto presentSceneAdress = Helper::PatternScan(Discord::GetDiscordModuleBase(),
                                                  "48 89 5C 24 ? 48 89 74 24 ? 57 48 83 EC 20 48 8B D9 41 8B F8");
//cant reach to here
std::cout << "after patternscan!" << std::endl;

it should print after patternscan! but it does not.

after looking into the PatternScan function it just breaks (how i found out

std::cout << "before for loop" << std::endl;

    for (auto i = 0ul; i < sizeOfImage - s; ++i)
    {
        bool found = true;
        for (auto j = 0ul; j < s; ++j)
        {
            if (scanBytes[i + j] != d[j] && d[j] != -1)
            {
                found = false;

                std::cout << "break now" << std::endl;
                break;

            }

        }

        if (found) { std::cout << "before return: " << reinterpret_cast<uintptr_t>(&scanBytes[i]) << std::endl; return reinterpret_cast<uintptr_t>(&scanBytes[i]); }

    }

console shows

before for loop and then spams break now

could it be the pointer being invalid?

new problem:

console gives OriginalPresent: 0x00007FFAE33165E0 CreateHook: 0x00007FFAE3306610

but not more. probably still invalid pointers. does someone know how to get them? if yes then please publish them
