In computing, DirectInput〔https://msdn.microsoft.com/en-us/library/windows/desktop/ee416842(v=vs.85).aspx〕〔https://msdn.microsoft.com/en-us/library/windows/desktop/bb318766(v=vs.85).aspx〕 is a deprecated Microsoft API for collecting input from a computer user, via input devices such as the mouse, keyboard, joystick or other game controllers. It also provides a system for ''action mapping,'' which allows the user to assign specific actions within a game to the buttons and axes of the input devices. Additionally it handles ''force-feedback'' (input/output) devices. Microsoft introduced a new input library called XInput specifically for the Xbox 360 controller. DirectInput and XInput provide benefits over normal Win32 input events: * they enable an application to retrieve data from input devices even when the application is in the background * they provide full support for any type of input device, as well as for ''force feedback'' * through ''action mapping'', applications can retrieve input data without needing to know what kind of device generated that input While DirectInput forms a part of the DirectX library, it has not been significantly revised since DirectX 8 (2001–2002). Microsoft recommends that new applications make use of the Windows message loop for keyboard and mouse input instead of DirectInput (as indicated in the Meltdown 2005 slideshow〔(【引用サイトリンク】title=Meltdown 2005 slideshow (.zip) )〕), and to use XInput instead of DirectInput for Xbox 360 controllers. == History == DirectX included DirectInput from version 1.0 (1995). It initially offered true support only for joysticks, as the mouse and keyboard modules simply provided wrappers to the standard Win32 API. DirectX version 3.0 (1996) added support for keyboards and mice; it also improved joystick support. DirectX 5.0 (1997) included greatly improved joystick support, including adding force feedback, increasing the number of buttons, changing the underlying device-driver model and incorporating a COM-based API. Mouse support also increased the number of buttons seen from four to eight. In DirectX 7.0 (1999- ), DirectInput added a long-promised feature of seeing individual mice much like individual joysticks, but the feature didn't work with the later released Windows XP, even though it works with Windows 98/Me and DirectX 9. DirectX 8.0 (2000), the last version with major changes, included action mapping and broader support for different types of devices. While Microsoft initially intended that DirectInput would handle all inputs, it hasn't turned out this way. Microsoft doesn't recommend using DirectInput for keyboards or mice, and has started pushing the newer XInput for Xbox 360 controllers.〔 〕 In Windows Vista, Windows 7 and later Windows versions, the in-built action mapping UI has been removed. DirectInput is not available for Windows Store apps. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DirectInput」の詳細全文を読む スポンサード リンク
