# DX11 Directx11 return code definition

I'm using windows 8 with DirectX11 to create a desktop application.

The function D3D11CreateDeviceAndSwapChain has several possible return codes as described here.

Although I can check for many of them, the ones starting with D3DERR_, like D3DERR_INVALIDCALL are not defined.

Googling a bit I found out they should be defined in D3DX11core.h, which is not included in the sdk.

Am I missing something?

If you include d3d11.h that should be enough as that should include all of what you need, you might need to include dxgi.h as well.

I'm including the following, but it still can't find the definition.

#include <dxgi.h>
#include <d3dcommon.h>
#include <d3d11_1.h>
#include <d3dcompiler.h>

just use #include <d3dx11.h> (or 11_1 if there is such a thing)

this may not get you the compiler though. it does gets you a DXGI device context, so it seems to include DXGI.

D3DERR_INVALIDCALL is defined in D3DX11core.h:

#define D3DERR_INVALIDCALL MAKE_D3DHRESULT(2156)

note that this is from the june 2010 sdk version of directx 11, not the win8 sdk version of dx11. there may be an 11.0 vs 11.1 version thing going on between them. Edited by Norman Barrows

I searched the whole "windows kits\8.0\include" directory but the only definition of D3DERR_INVALIDCALL is inside d3d9helper.h.

Apparently the problem is just that the documentation is not updated about the fact that they dropped the error codes that begin with D3DERR_.

Inside winerror.h I could find all the definitions for dxgi, d3d10 and d3d11 errors, but they are named and defined differently, for example:

//
// DXGI error codes
//

//
// MessageId: DXGI_ERROR_INVALID_CALL
//
// MessageText:
//
// The application made a call that is invalid. Either the parameters of the call or the state of some object was incorrect.
// Enable the D3D debug layer in order to see details via debug messages.
//
#define DXGI_ERROR_INVALID_CALL          _HRESULT_TYPEDEF_(0x887A0001L)


where _HRESULT_TYPEDEF_ is just

#define _HRESULT_TYPEDEF_(_sc) ((HRESULT)_sc)

i suspected something like this.

was there a specific directx 11.1 routine that said it returned d3derr_invalid call? no, cause you were using create dev & swap chain, just like i was a few days ago myself. so you were just trying to trap and process the documented return codes, eh?   too bad their docs suck.

as soon as i saw that create dev and swap chain returned s_ok instead of d3d_ok, i realized dx11 error codes are a whole new ballgame.

they apparently have both the june 2010 and win 8 docs posted on msdn, identical info. apparently true for june 2010 sdk, and not for win8 sdk. you may want to "send a comment to microsoft about this document".

Yes, I was getting some errors so I wanted to catch all the possible return codes.

I sent a mail, hopefully they will update the documentation.

• Hi, can somebody please tell me in clear simple steps how to debug and step through an hlsl shader file?
I already did Debug > Start Graphics Debugging > then captured some frames from Visual Studio and
double clicked on the frame to open it, but no idea where to go from there.

I've been searching for hours and there's no information on this, not even on the Microsoft Website!
They say "open the  Graphics Pixel History window" but there is no such window!
Then they say, in the "Pipeline Stages choose Start Debugging"  but the Start Debugging option is nowhere to be found in the whole interface.
Also, how do I even open the hlsl file that I want to set a break point in from inside the Graphics Debugger?

All I want to do is set a break point in a specific hlsl file, step thru it, and see the data, but this is so unbelievably complicated

• I finally ported Rastertek's tutorial # 42 on soft shadows and blur shading. This tutorial has a ton of really useful effects and there's no working version anywhere online.
Unfortunately it just draws a black screen. Not sure what's causing it. I'm guessing the camera or ortho matrix transforms are wrong, light directions, or maybe texture resources not being properly initialized.  I didnt change any of the variables though, only upgraded all types and functions DirectX3DVector3 to XMFLOAT3, and used DirectXTK for texture loading. If anyone is willing to take a look at what might be causing the black screen, maybe something pops out to you, let me know, thanks.

Also, for reference, here's tutorial #40 which has normal shadows but no blur, which I also ported, and it works perfectly.

Is Direct3D 11 an api function like glMemoryBarrier in OpenGL? For example, if binds a texture to compute shader, compute shader writes some values to texture, then dispatchCompute, after that, read texture content to CPU side. I know, In OpenGL, we could call glMemoryBarrier before reading to assure that texture all content has been updated by compute shader.
How to handle incoherent memory access in Direct3D 11? Thank you.

Atum engine is a newcomer in a row of game engines. Most game engines focus on render
techniques in features list. The main task of Atum is to deliver the best toolset; that’s why,
as I hope, Atum will be a good light weighted alternative to Unity for indie games. Atum already
has fully workable editor that has an ability to play test edited scene. All system code has
simple ideas behind them and focuses on easy to use functionality. That’s why code is minimized
as much as possible.
Currently the engine consists from:
- Scene Editor with ability to play test edited scene;
- Powerful system for binding properties into the editor;
- Render system based on DX11 but created as multi API; so, adding support of another GAPI
is planned;
- Controls system based on aliases;
- Font system based on stb_truetype.h;
- Support of PhysX 3.0, there are samples in repo that use physics;
- Network code which allows to create server/clinet; there is some code in repo which allows
to create a simple network game
I plan to use this engine in multiplayer game - so, I definitely will evolve the engine. Also
I plan to add support for mobile devices. And of course, the main focus is to create a toolset
that will ease games creation.

Video of work process in track based editor can be at follow link:

• I made a spotlight that
1. Projects 3d models onto a render target from each light POV to simulate shadows
2. Cuts a circle out of the square of light that has been projected onto the render target
as a result of the light frustum, then only lights up the pixels inside that circle
(except the shadowed parts of course), so you dont see the square edges of the projected frustum.

After doing an if check to see if the dot product of light direction and light to vertex vector is greater than .95
to get my initial cutoff, I then multiply the light intensity value inside the resulting circle by the same dot product value,
which should range between .95 and 1.0.

This should give the light inside that circle a falloff from 100% lit to 0% lit toward the edge of the circle. However,
there is no falloff. It's just all equally lit inside the circle. Why on earth, I have no idea. If someone could take a gander
