Problems or Questions regarding the hack?
Take a look at our FAQ

To use this overlay you need Visual Studio 2013 or higher or another IDE which supports C++ 11/15.

Supported overlay functions:

interface based
directX 9 overlay
render function callback

Supported surface functions:

bordered box
outlined bordered box
rect angle
outlined rect angle
line
string

All you need is in your thread/main one pointer to the overlay. With that pointer we will prepare our fonts, register callback functions, calling the render thread and release everything at the end.

CPP Code:

auto &pOverlay = Overlay::IOverlay::GetInstance( );
pOverlay = std::make_shared< Overlay::CD3D9Overlay >( );
 
// Since we have a pointer to the overlay we can now prepare some fonts which
// we wanna use later in our project
pOverlay->GetSurface( )->PrepareFont( "Default", "Arial", 14, FW_BOLD, 0, 0, FALSE );
 
// After we prepared our fonts, we're going to create the overlay. All we need here is
// the target window title. The overlay window title/class gets randomized
if( pOverlay->Create( "Counter-Strike: Global Offensive" ) )
{
    // before we start our render procedure we register our needed callback function(s)
    // which the overlay draws only when the game is the current foreground window
}

Now we have to options to add some functions in our callback. The first one is create a new function and pass it. The function need the following parameters:

CPP Code:

void TestCallbackFunction( Overlay::IOverlay *thisptr, std::shared_ptr< Overlay::ISurface > pSurface )
{
    g_pGui->Render( );
    pSurface->String( 5, 5, "Default", 0xFFFFFFFF, "Hello from test callback" );
}

Last but not least: call the render function while the function returns true. After that, shutdown the overlay and exit your application.

CPP Code:

auto &pOverlay = Overlay::IOverlay::GetInstance( );
pOverlay = std::make_shared< Overlay::CD3D9Overlay >( );
 
// Since we have a pointer to the overlay we can now prepare some fonts which
// we wanna use later in our project
pOverlay->GetSurface( )->PrepareFont( "Default", "Arial", 14, FW_BOLD, 0, 0, FALSE );
 
// After we prepared our fonts, we're going to create the overlay. All we need here is
// the target window title. The overlay window title/class gets randomized
if( pOverlay->Create( "Counter-Strike: Global Offensive" ) )
{
    // before we start our render procedure we register our needed callback function(s)
    // which the overlay draws only when the game is the current foreground window
 
    pOverlay->AddToCallback( TestCallbackFunction );
 
    // Lambda method
    auto LambdaCallbackFunction = []( Overlay::IOverlay *thisptr, std::shared_ptr< Overlay::ISurface > pSurface )
    {
        pSurface->String( 5, 20, Overlay::Color( 255, 255, 255 ), "Hello from lambda callback" );
    };
 
    pOverlay->AddToCallback( LambdaCallbackFunction );
 
    while( pOverlay->Render( ) )
        std::this_thread::sleep_for( std::chrono::milliseconds( 1 ) );
 
    pOverlay->Shutdown( );
}

In your gui/esp you can draw via the IOverlay::GetInstance( )->GetSurface( ) function if you setuped the overlay as I wrote it in the tutorial above this sentence.
