Tibia Anti-Idle

[Notoriouss]

Made for fun, good for studying Windows API
Btw, it only works on Windows ...

The inexistence of the Tibia window will not stop it but it will only works on the opened Tibia window

And there's no way to stop it, unfortunately you'll have to close it at the Task Manager, due to the command Sleep that lock the console and makes impossible to detect a key press at the right time

    if (Tibia != NULL)

            return true;
    
    return false;
}

{
    for (UINT Dir = DIR_LEFT; Dir <= DIR_DOWN; Dir++)
    {
        SetPlayerDirection((DIRS_T)Dir);
        Sleep(CONST_DIR_DELAY);
    }
}

int GetIntervalInput()
{
    string Interval;
    while (!IsStringNumber(Interval)) {
        cout << "Type the interval in seconds: ";
        cin >> Interval; 
        system("CLS");
    }
    return atoi(Interval.c_str());
}

int main(int argc, char *argv[])
{
    SetConsoleTitle("Notorious Anti-Idle");
    int Interval = GetIntervalInput();
    ShowWindow( GetConsoleWindow(), SW_HIDE );
    SwitchToThisWindow( GetTibiaWindow(), true );

    while (true) 
    {
        Sleep(Interval*1000);
        MovePlayer();

    return true;
