C++ External Cheat Development Tutorial359

IntroductionExternal cheats are a type of cheat that is injected into a game's memory space. This allows them to access and modify the game's data, such as player positions, health, and ammo. External cheats are generally considered to be more reliable and harder to detect than internal cheats, which are injected into the game's executable file.

Prerequisites* A C++ compiler
* A debugger
* A memory editor
* A basic understanding of C++

Step 1: Creating a New ProjectCreate a new C++ project in your preferred IDE. Add the following header files to your project:
```cpp
#include
#include
```

Step 2: Getting the Game's Process IDThe first step is to get the process ID (PID) of the game that you want to cheat. You can do this using the `CreateToolhelp32Snapshot` and `Process32First` functions.
```cpp
DWORD GetGameProcessId(const wchar_t* gameName) {
HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
if (hSnapshot == INVALID_HANDLE_VALUE) {
return 0;
}
PROCESSENTRY32 processEntry;
= sizeof(PROCESSENTRY32);
if (!Process32First(hSnapshot, &processEntry)) {
CloseHandle(hSnapshot);
return 0;
}
do {
if (wcscmp(, gameName) == 0) {
CloseHandle(hSnapshot);
return processEntry.th32ProcessID;
}
} while (Process32Next(hSnapshot, &processEntry));
CloseHandle(hSnapshot);
return 0;
}
```

Step 3: Opening the Game's ProcessOnce you have the game's PID, you can open its process using the `OpenProcess` function.
```cpp
HANDLE OpenGameProcess(DWORD pid) {
return OpenProcess(PROCESS_ALL_ACCESS, FALSE, pid);
}
```

Step 4: Reading and Writing Game MemoryTo read and write game memory, you can use the `ReadProcessMemory` and `WriteProcessMemory` functions.
```cpp
BOOL ReadGameMemory(HANDLE hProcess, DWORD address, LPVOID buffer, DWORD size) {
SIZE_T bytesRead;
return ReadProcessMemory(hProcess, (LPCVOID)address, buffer, size, &bytesRead);
}
BOOL WriteGameMemory(HANDLE hProcess, DWORD address, LPVOID buffer, DWORD size) {
SIZE_T bytesWritten;
return WriteProcessMemory(hProcess, (LPVOID)address, buffer, size, &bytesWritten);
}
```

Step 5: Finding Game OffsetsGame offsets are the addresses of specific data in the game's memory. You can find game offsets using a memory editor or by searching for them online.

Step 6: Creating the CheatNow that you have all the necessary information, you can start creating the cheat. The cheat can be anything you want, such as a health hack, a speed hack, or an aimbot.

Step 7: Injecting the CheatThe final step is to inject the cheat into the game's memory. You can do this using the `CreateRemoteThread` function.
```cpp
BOOL InjectCheat(HANDLE hProcess, LPVOID cheatAddress) {
HANDLE hThread = CreateRemoteThread(hProcess, NULL, 0, (LPTHREAD_START_ROUTINE)cheatAddress, NULL, 0, NULL);
if (hThread == INVALID_HANDLE_VALUE) {
return FALSE;
}
CloseHandle(hThread);
return TRUE;
}
```

ConclusionThis tutorial has shown you how to create a basic external cheat for a game. With a little practice, you can create more complex cheats that can give you a significant advantage in online games.
