Games that use XInput that do not filter dead zone at all will experience poor gameplay. There is also a dead zone for the 2 analog triggers. The dead zone is "movement" values reported by the controller even when the analog thumbsticks are untouched and centered. In order for users to have a consistent gameplay experience, your game must implement dead zone correctly. We recommend that you space out checks for new controllers every few seconds instead. If it differs, then the application should check the Gamepad member of the XINPUT_STATE structure to get more detailed state information.įor performance reasons, don't call XInputGetState for an 'empty' user slot every frame.
If dwPacketNumber does not change between two sequential calls to XInputGetState, then there has been no change in state. The dwPacketNumber member of the XINPUT_STATE structure can be used to check if the state of the controller has changed since the last call to XInputGetState. Once the state has been retrieved in a XINPUT_STATE structure, you can check it for changes and get specific information about controller state. In the above example, g_Controllers represents such a structure. Applications should define a structure to hold internal controller information this information should be compared against the results of XInputGetState to determine what changes, such as button presses or analog controller deltas, were made that frame. Note that the return value of XInputGetState can be used to determine if the controller is connected. Simply get the state of the controller from XInput. ZeroMemory( &state, sizeof(XINPUT_STATE) ) To retrieve state, use the XInputGetState function: DWORD dwResult įor (DWORD i=0 i< XUSER_MAX_COUNT i++ ) From frame to frame in a game application, state should be retrieved and game information updated to reflect the controller changes. Throughout the duration of an application, getting state from a controller will probably be done most often.
A dwUserIndex value of 0 corresponds to the top-left quadrant the numbering proceeds around the ring in clockwise order.Īpplications should support multiple controllers. The number corresponds to the port that the controller is plugged into, and is not modifiable.Įach controller displays which ID it is using by lighting up a quadrant on the "ring of light" in the center of the controller. This ID will be in the range of 0-3 and is set automatically by XInput. The XInput functions all require a dwUserIndex parameter that is passed in to identify the controller being set or queried. The XInput API supports up to four controllers connected at any time. Using the XInput functions, you can retrieve controller state, get headset audio IDs, and set controller rumble effects. Using XInput is as simple as calling the XInput functions as required. You can then use the Core Audio APIs to receive voice input and send sound output. You can call the XInputGetAudioDeviceIds or legacy XInputGetDSoundAudioDeviceGuids function to obtain the device identifiers that correspond to the devices for the microphone and headphone. The headset has a microphone for voice input, and a headphone for sound output.
Optionally, a headset can be connected to the controller. The speeds of these motors are specified in the XINPUT_VIBRATION structure that is passed to the XInputSetState function to set vibration effects. The controller also has two vibration motors to supply force feedback effects to the user. The states of each of these inputs are returned in the XINPUT_GAMEPAD structure when the XInputGetState function is called. The Xbox Controller has two analog directional sticks, each with a digital button, two analog triggers, a digital directional pad with four directions, and eight digital buttons. Controllers that have the headset attached can also be queried for sound input and output devices that can be used with the headset for voice processing. Using this API, any connected Xbox Controller can be queried for its state, and vibration effects can be set.

Applications can use the XInput API to communicate with these controllers when they are plugged into a Windows PC (up to four unique controllers can be plugged in at a time). The Xbox console uses a gaming controller that is compatible with Windows.

This topic provides a brief overview of the capabilities of XInput and how to set it up in an application. XInput enables Windows applications to process Xbox Controller interactions (including controller rumble effects and voice input and output).
