Overview

About The Project

Helper library for external windows game hacking.

Collaborative work provided by the CasualCommunity

Installation

1. Download current release ("CasualLibrary1.0.rar") from the release section
2. Extract *.h and *.lib file(s) at appropriate location in your project directory.
3. Include them into your project.

Build from source

If You want or need to build the project from source, You can either

1. Download the whole repository
2. Open the VS project (CasualLibrary.sln) with Visual Studio
3. Right click the CasualLibrary and hit build

Or use cmake

1. Create new folder in the projects root directory: mkdir build
2. Navigate to the new folder: cd build
3. Run cmake: cmake ..
4. Build: cmake --build . (tested with "Visual Studio 16 2019" and "GNU 6.3.0"/"MinGW Makefiles")

Usage

bare-bones setup

external

#include <iostream>
#include "CasualLibrary.hpp"

int main(){
    Memory::External memory = Memory::External("target.exe");
    Memory::External memoryDebug = Memory::External("target.exe", true); //use for debug messages
}

internal

Sample dll including the library

#include <Windows.h>
#include <iostream>

#include "CasualLibrary.hpp"

HMODULE myhModule;

DWORD __stdcall EjectThread(LPVOID lpParameter) {
    Sleep(100);
    FreeLibraryAndExitThread(myhModule, 0);
}

DWORD WINAPI Menue() {
    AllocConsole();
    FILE* fp;
    freopen_s(&fp, "CONOUT$", "w", stdout); // output only
    std::cout << "Running tests ...\n\n";

    //add Code here

    while (1) {
        Sleep(100);
        if (GetAsyncKeyState(VK_NUMPAD0))
            break;
    }
    fclose(fp);
    FreeConsole();
    CreateThread(0, 0, EjectThread, 0, 0, 0);
    return 0;
}


BOOL APIENTRY DllMain(HMODULE hModule,
    DWORD  ul_reason_for_call,
    LPVOID lpReserved
    )
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
        myhModule = hModule;
        CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)Menue, NULL, 0, NULL);
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
        break;
    }
    return TRUE;
}

read/write memory

external

//works for all types including uintptr_t, int, double etc. as well as custom structs and classes.
//does NOT work for arrays/vectors
Address address = Address(0x2240001C);
// read integer stored at address
int test = memory.read<int>(address);
// read string
std::string word = memory.read<std::string>(address);
//write value 5 starting at given address
memory.write<int>(address, 5);
//To check the memory before accessing it set memoryCheck = true
int testSave = memory.read<int>(address, true);
memory.write<int>(address, 5, true);

get module base address

external

Address clientAddr = memory.getModule("client.dll");

internal

Address clientAddr = Memory::Internal::getModule("client.dll");

get address from static pointer + offsets

external

Address baseAddr = memory.getModule("ZW64.exe");
Address healthAddr = memory.getAddress(baseAddr+0x00003648, { 0x40,0xE4 });

internal

Address baseAddr = Memory::Internal::getModule("ZW64.exe");
Address healthAddr = Memory::Internal::getAddress(baseAddr+0x00003648, { 0x40,0xE4 });

AOB Scanner

external

Address address = memory.findSignature(0x7FF702CB5D00, "? 39 05 F0 A2 F6 FF" , 10000);

internal

Address address = Memory::Internal::findSignature(0x7FF702CB5D00, "? 39 05 F0 A2 F6 FF" , 10000);
