When the camera was altered from a y-axis rotation camera to a zoom based one, certain lines of the code were not changed to comply with the new projection to world matrix.

Specifically, line 83 in RaytracingAOPC12.cpp showing:
m_sceneCB[frameIndex].projectionToWorld = XMMatrixInverse(nullptr, viewProj);

Needs to be transposed as the entries are no longer symmetric:
m_sceneCB[frameIndex].projectionToWorld = XMMatrixTranspose(XMMatrixInverse(nullptr, viewProj));

Consequently, line 86 of AORaytracing.hlsl must be removed as it is no longer needed as a temporary fix:
screenPos *= 20;

Lastly, the readme seems to be missing information about the camera controls A and D for zooming in and out.

Cheers,
Kevin Pick

\UWPSamples\System\GamepadVibrationUWP
when used with the official Xbox controller via Bluetooth, the vibration feedback seems to have lagging issues and sporadic trigger level issues, especially with the left trigger (LT).

The exact Xbox controller I am using is
https://www.amazon.com/dp/B08K4HLCPR?ref=ppx_yo2ov_dt_b_product_details&th=1

I am on Windows 11 Home 23H2 and I have updated the controller firmware to the latest using the Xbox Accessories app.

The problem does not happen when the controller is connected via USB with a wire, the problem only happens when the controller is connected wirelessly via Bluetooth.

I have tested GamepadVibrationUWP on the Xbox One with its stock controller and that appears to be fine. The problem only happens on Windows.

I tried to run the SimpleBezierUWP sample on Xbox Series X and S as a UWP game app (using retail consoles in devmode) and it is not working correctly. The rendered geometry simply won't show up in the viewport and no errors are logged on the debug console in Visual Studio. Investigating the problem a little bit using D3D11_QUERY_DATA_PIPELINE_STATISTICS revealed that the hull shader is still executed on the expected number of control points but no domain shader innvocations are recorded. From here on, I'm not sure how to debug this further. Is this a bug? Or is tessellation not supported on these devices and UWP?

Error C1083 Shaders/Compiled/XboxOnePBREffect_VSConstant.inc: No such file or directory, DirectXTK_XboxOneXDK_2015 <..>\Xbox-ATG-Samples\Kits\DirectXTK\Src\PBREffect.cpp 87
This error i got whe trying to compile 'Gamepad' sample.
As i see, there are no some .inc files with names such as 'XboxOnePBREffect_VSConstant.inc'
These includes don't work (PBREffect.cpp) for Xbox One part :

#include "Shaders/Compiled/XboxOnePBREffect_VSConstant.inc"
#include "Shaders/Compiled/XboxOnePBREffect_VSConstantVelocity.inc"
#include "Shaders/Compiled/XboxOnePBREffect_VSConstantBn.inc"

After adding GraphicsMemory files to my project I start to got exceptions (C++ exception in debug build and 0xC00005 in release) when activating multithreading mode. Single threading works OK. Do GraphicsMemory from DirectXTK12 is MT-compatible ?

The usage is simple - for uploading 1 constant buffer into accelerator memory:

m_graphicsMemory = std::make_unique(m_D3D12device.Get());
m_computeHeap = m_graphicsMemory->Allocate((size_t)(4 * 1024));

SharedGraphicsResource* pUploadHeap = &m_computeHeap;
SAD_CS_PARAMS* pCBsadCSparams = reinterpret_cast<SAD_CS_PARAMS*> (pUploadHeap->Memory());

'filling memory here'

m_graphicsMemory->Commit(m_computeCommandQueue.Get());

Exception occur in the 'external' application that load this plugin after returning from the function with this sequence.

Unfortunately exception looks like happens in the server-application so remote debug session simply closes without breaking at the point of error.

Hi, I am looking for low-level DirectX 12 tutorials for UWP so that I can write my own engine on Xbox One. I saw some low-level tutorials here:

https://github.com/Microsoft/DirectX-Graphics-Samples/tree/master/Samples/UWP/D3D12HelloWorld/src/HelloTexture

But I could not get these samples to compile or run on Xbox One. Are there any tutorials for low-level DirectX 12 that can run on Xbox One?

I saw there is a constant buffer but no usage in shader under directx 12

Can you help compile FlightStick and provide a sideload package?
For some reason, I can't compile this project, and the alternative Xbox-GDK-Samples/Gamepad also won't compile, but I desperately need this feature for some test, I know it sounds a bit incomprehensible, but is it possible to do this?😢

Working with ChatGPT, I spent 3 hours trying to add some sort of file picker to SimpleSpatialPlaySoundUWP.cpp.

Despite very specific and detailed instructions (in both directions) in the end I could not find a file picker method that could be compiled, with the example, without errors.

Adding winrt to the project resulted in a ton of errors (VS2022).

Asking specifically for a UWP solution, that didn't rely on winrt, also did not result in any picker function compiling with the code (tried 3 or 4 iterative variants, feeding the errors back to ChatGPT).

Please consider adding a file picker to this sample project. There doesn't seem to be ANY file pickers used anywhere in the UWP sample code.

The target platform is Windows 10/11 (not Xbox).

I have an issue somewhat similar to #22, but I don't get any errors at all. From my own testing, the code runs through all the force feedback checks and ends up runningm_effect->Start(), but the wheel doesn't budge. Essentially all other programs work fine, games and wheel testers alike.

Hi, I had problems building the SimplePlay3DSpatialSoundUWP audio sample due to "MSB4057: The target 'MarkupCompilePass1' does not exist in the project" against the DirectXTK project.

Finally solved this by installing the 10.0.14393 Windows 10 SDK for Visual Studio Built Tools 2017 15.2 (26530.15). This is not part of the default build tools install.

Please add build tools and versions to the prereqs, and if there's a way to adjust the build tools installer to include the latest version of all required components, that would be great.

I tried to run the InputInterfacingUWP because I want to use the Force Feedback feature on my Logitech G920 steering wheel.

When I run the code without connecting the steering wheel, the app window comes up and reports "No navigation input connected" - as expected.

However, when the steering wheel is connected, the window pops up and immediately closes.

In debug mode, I see these error messages:

I'm using Visual Studio 17 (15.9), Windows 10 SDK 10.0.18362.0. (I also tried with the Windows 10 SDK 10.0.17763.0, but I got errors in the DirectXTK code)

Is there other XBox software I need to download? Have you tested this code on the G920 steering wheel? Is this a bug with the steering wheel?

The RawInputControllerUWP works as expected using the Logitech G920 steering wheel, so I'm wondering if it is a problem only with the ForceFeedback functionality?

Do you know how to solve the "onecoreuap\xbox\devices\api\winrt\hidforcefeedback.cpp(415)\Windows.Gaming.Input.dll!00007FFD1AA50B10: (caller: 00007FFD1AA50864) LogHr(1) tid(607c) 80070005 Access is denied." error?

Is it possible to explicitly control DirectX 12 resource residency by moving textures or buffers to / from ESRAM? I think I can assume that in certain cases Xbox will move stuff for me implicitly, but if I want a specific piece of data stay there I need some form of explicit control. Is there any info / documentation on that or it's not even possible? (context: I'm under Xbox Live Creators program)

Is there any documentation anywhere about the dependancies? I cannot get this to compile no matter what I do. Just 1000+ errors.

What do I need to do to get any of the WinRT samples to compile on VS2022? I didn't imagine not getting anywhere when I tried to access any of the samples. I got thrown to the samples page and thought "oh, cool! I can test some stuff out." Nope. No documentation. Nothing. Just stop and go do something else. I feel like there's something vital missing there.

Hello!

I'm working with Unity3D and i have a released game which i would like to bring to Xbox, i setted up my consoles with dev mode and deployment working well but, i would like to make the game on Xbox One X in 4k, but i can't figouring out how to iplement native 4k game starting, Unity3D make a Visual Studio project with IL2CPP backend what i can deploy to Xbox but in this project a can't find where i can set the resolution also if i try to set the resolution from ingame the game freeze and the cpu usage goes to null so i thinking to implement dx device creation from the SimplePBR12_UWP but how can i do that?

you can download my sample to see how Unity3D generate the project.

Thank you!

I retargeted the solution to toolset v142. VS Enterprise 2019 version 16.7.0. In this project for example the red only appears in debug mode.

Is it possible to profile a UWP game under Xbox Live Creators Program with PIX? I see some UWP examples are using it, but I can't find official docs on this.

Thanks!

I use DX::ReadData() function to load shader .cso file (as from sample SimpleCompute -

I not experience any issues at development Windows10 machine. But with release version users start to complain on Unhandled C++ exception crash at startup.

I add exception handler around DX::ReadData() call:

// load compute shader
 std::vector<uint8_t> computeShaderBlob;
 try {
   computeShaderBlob = DX::ReadData(L"Compute.cso");
 }
 catch (std::exception& e)
 {
   env->ThrowError(
     "MAnalyse: Can not load file Compute.cso %s", e.what()
   ); 
 }

And users report error:
MAnalyse: Can not load file Compute.cso ReadData
(https://forum.doom9.org/showthread.php?p=1962099#post1962099 )

The solution at user-side was mostly like to place compiled executable (.dll and launching .exe and compute.cso) in some simple path like c:\AVS and it works. The non-working path may be some like c:\plugins64+ . Can the + char cause some error in function ReadData ? Can ReadData return more detailed error about what is happens ? May I not right use e.what() method of return error description ?

Please provide Windows store versions so we can simply download and test rather than build and compile

uwp inputinterfaceSample ，Demo program does not work properly

The initial release date for the SSAO v. AO sample under Raytracing is incorrect in the docx.

I'm trying to build "SimpleMSAA_PC12" project but it doesn't work with any of my installed SDKs (10.0.19041.0, 10.0.18362.0, and 10.016299.0). From the looks of it (see image), VS installer doesn't have any options to install SDKs older than 10.016299.0, is there any way to install 10.0.14393.0 SDK? Is there any workaround to use later SDKs with the project?

I get a compile error, see output below. Looks like it's just the FallbackLayer and I'm guessing I haven't set something extra outside of the project.
Thanks for any help!

Hi,

I'm relatively new to UWP development on Xbox One and I'm wondering what kind of performance profiling tools are available for this platform. Is there something similar to the ETW system present on desktop Windows 10?

Thanks

SimplePlay3DSpatialSoundUWP (and potentially others too) crash when the user changes the "Spatial sound" setting from e.g. Windows Sonic for Headphones to OFF. (Also crashes at any other combination.)

Callstack:

SimplePlay3DSpatialSound.exe!ISACRenderer::IsActive() Line 29 C++
SimplePlay3DSpatialSound.exe!`anonymous namespace'::SpatialWorkCallback(_TP_CALLBACK_INSTANCE * Instance, void * Context, _TP_WORK * Work) Line 37 C++
[External Code]

Reason:
Sink->m_renderer in SpatialWorkCallback is NULL.

• it works extremely slow in debug mode under Xbox one.

• unlaunchable in release mode - exceptions

Xbox has installed updates
