Thread: Beginning C++ with MS Github Tutorial Boilerplate Code Difference

Hi,


I'm starting out with C++ and DirectX and I decided to follow along with the micrsoft github tutorial on DirectX12 found here The basic game loop * Microsoft/DirectXTK Wiki * GitHub.


I installed the following workloads:

• Game development with C++
• Desktop development with C++
• Universal Windows Platform development
• C++ Universal Windows Platform tools

The example in the link above says I should see this code:

Code:

// Initialize the Direct3D resources required to run.
void Game::Initialize(HWND window, int width, int height)
{
    m_window = window;
    m_outputWidth = std::max( width, 1 );
    m_outputHeight = std::max( height, 1 );


    CreateDevice();


    CreateResources();


    // TODO: Change the timer settings if you want something other than the default
    // variable timestep mode.
    // e.g. for 60 FPS fixed timestep update logic, call:
    /*
    m_timer.SetFixedTimeStep(true);
    m_timer.SetTargetElapsedSeconds(1.0 / 60);
    */
}

However, when I created a project I found some of the code above is in a different function:

Code:

// Loads and initializes application assets when the application is loaded.
App1Main::App1Main()
{
    // TODO: Change the timer settings if you want something other than the default variable timestep mode.
    // e.g. for 60 FPS fixed timestep update logic, call:
    /*
    m_timer.SetFixedTimeStep(true);
    m_timer.SetTargetElapsedSeconds(1.0 / 60);
    */
}

And the Initialize function has this code instead:

Code:

// The first method called when the IFrameworkView is being created.
void App::Initialize(CoreApplicationView^ applicationView)
{
    // Register event handlers for app lifecycle. This example includes Activated, so that we
    // can make the CoreWindow active and start rendering on the window.
    applicationView->Activated +=
        ref new TypedEventHandler<CoreApplicationView^, IActivatedEventArgs^>(this, &App::OnActivated);


    CoreApplication::Suspending +=
        ref new EventHandler<SuspendingEventArgs^>(this, &App::OnSuspending);


    CoreApplication::Resuming +=
        ref new EventHandler<Platform::Object^>(this, &App::OnResuming);
}

Teaching myself and I'm stuck because the code on my machine is different from the tutorial. Boilerplate should be the same. I made no alterations. Code runs and makes a spinning cube.


What am I missing here? Is the tutorial out of date or did I do something wrong?


I'm using VS2019 if that matters.


Thanks

Thanks for the insight. I thought I was going crazy as C++ has changed alot in the years since i used it last (2005). I found a template VSIX file belonging to that tutorial and installed it for VS2017. Everything works as it should and the C++ code on the site is the same as the template files.
