This package contains the "DirectX Tool Kit", a collection of helper classes for writing Direct3D 11 C++ code for Universal Windows Platform (UWP) apps for Windows 11, Windows 10, Xbox One, and Win32 desktop applications for Windows 7 Service Pack 1 or later.

This code is designed to build with Visual Studio 2019 (16.11), Visual Studio 2022, clang for Windows v12 or later, or MinGW 12.2. Use of the Windows 10 May 2020 Update SDK (19041) or later is required for Visual Studio.

These components are designed to work without requiring any content from the legacy DirectX SDK. For details, seeWhere is the DirectX SDK?.

• Inc\

  • Public Header Files (in the DirectX C++ namespace):

    • Audio.h - low-level audio API using XAudio2 (DirectXTK for Audio public header)
    • BufferHelpers.h - C++ helpers for creating D3D resources from CPU data
    • CommonStates.h - factory providing commonly used D3D state objects
    • DDSTextureLoader.h - light-weight DDS file texture loader
    • DirectXHelpers.h - misc C++ helpers for D3D programming
    • Effects.h - set of built-in shaders for common rendering tasks
    • GamePad.h - gamepad controller helper using XInput, Windows.Gaming.Input, or GameInput
    • GeometricPrimitive.h - draws basic shapes such as cubes and spheres
    • GraphicsMemory.h - helper for managing dynamic graphics memory allocation
    • Keyboard.h - keyboard state tracking helper
    • Model.h - draws meshes loaded from .CMO, .SDKMESH, or .VBO files
    • Mouse.h - mouse helper
    • PostProcess.h - set of built-in shaders for common post-processing operations
    • PrimitiveBatch.h - simple and efficient way to draw user primitives
    • ScreenGrab.h - light-weight screen shot saver
    • SimpleMath.h - simplified C++ wrapper for DirectXMath
    • SpriteBatch.h - simple & efficient 2D sprite rendering
    • SpriteFont.h - bitmap based text rendering
    • VertexTypes.h - structures for commonly used vertex data formats
    • WICTextureLoader.h - WIC-based image file texture loader
    • XboxDDSTextureLoader.h - Xbox One exclusive apps variant of DDSTextureLoader

• Src\

  • DirectXTK source files and internal implementation headers

• Audio\

  • DirectXTK for Audio source files and internal implementation headers

• MakeSpriteFont\

  • Command line tool used to generate binary resources for use with SpriteFont

• XWBTool\

  • Command line tool for building XACT-style wave banks for use with DirectXTK for Audio's WaveBank class

• build\

  • Contains YAML files for the build pipelines along with some miscellaneous build files and scripts.

• Starting with the February 2023 release, the Mouse class implementation of relative mouse movement was updated to accumulate changes between calls toGetState. By default, each time you callGetState the deltas are reset which works for scenarios where you use relative movement but only call the method once per frame. If you call it more than once per frame, then add an explicit call toEndOfInputFrame to use an explicit reset model instead.

• As of the September 2022 release, the library makes use of C++11 inline namespaces for differing types that have the same names in the DirectX 11 and DirectX 12 version of theDirectX Tool Kit. This provides a link-unique name such asDirectX::DX11::SpriteBatch that will appear in linker output messages. In most use cases, however, there is no need to add explicitDX11 namespace resolution in client code.

• Starting with the July 2022 release, thebool forceSRGB parameter for DDSTextureLoaderEx functions is now aDDS_LOADER_FLAGS typed enum bitmask flag parameter. This may have abreaking change impact to client code. Replacetrue withDDS_LOADER_FORCE_SRGB andfalse withDDS_LOADER_DEFAULT.

• As of the October 2021 release, the DGSLEffect no longer directly supports skinning. Instead, make use ofSkinnedDGSLEffect which is derived from DGSLEffect.

• Starting with the June 2020 release, this library makes use oftyped enum bitmask flags per the recommendation of theC++ Standard section17.5.2.1.3 Bitmask types. This may havebreaking change impacts to client code:

  • You cannot pass the0 literal as your flags value. Instead you must make use of the appropriate default enum value:AudioEngine_Default,SoundEffectInstance_Default,ModelLoader_Clockwise, orWIC_LOADER_DEFAULT.

  • Use the enum type instead ofDWORD if building up flags values locally with bitmask operations. For example,WIC_LOADER_FLAGS flags = WIC_LOADER_DEFAULT; if (...) flags |= WIC_LOADER_FORCE_SRGB;

• The UWP projects and the Win10 classic desktop project include configurations for the ARM64 platform. Building these requires installing the ARM64 toolset.

• When using clang/LLVM for the ARM64 platform, the Windows 11 SDK (22000) or later is required.

• TheCompileShaders.cmd script must have Windows-style (CRLF) line-endings. If it is changed to Linux-style (LF) line-endings, it can fail to build all the required shaders.

• Xbox One support for DirectX 11 requires the legacy Xbox One XDK. See February 2023 or earlier releases ofDirectX Tool Kit for the required project files.
