makVrv::DtOpenVREventManager Class Reference

Detailed Description

This class is responsible for processing SteamVR/OpenVR controller events and translating them into the common VR controller event format. It communicates with the OpenVR API to retrieve controller state information and dispatches controller events to registered event processors.

Note

This class is created automatically by the DtVirtualRealityDriver and is not intended to be instantiated directly by users.

Constructor & Destructor Documentation

DtOpenVREventManager() [1/2]

makVrv::DtOpenVREventManager::DtOpenVREventManager ( )

private

Unused default constructor.

Private constructor to prevent direct instantiation. Use the instance() method to get the singleton instance instead.

~DtOpenVREventManager()

virtual makVrv::DtOpenVREventManager::~DtOpenVREventManager ( )

overridevirtual

Virtual destructor.

Cleans up OpenVR event manager resources and releases connections to the OpenVR API.

DtOpenVREventManager() [2/2]

makVrv::DtOpenVREventManager::DtOpenVREventManager ( DtDe & de )

protected

Constructor.

Parameters

de	Reference to the display engine

Initializes the OpenVR event manager with a reference to the display engine. This constructor is only called by the registerInstance method and should not be called directly.

References de().

Member Function Documentation

instance()

static DtVirtualRealityEventManager & makVrv::DtOpenVREventManager::instance ( DtDe & de )

static

Gets the singleton instance of the OpenVR event manager.

Parameters

de	Reference to the display engine

Returns

Reference to the singleton instance

Exceptions

DtCorruptedState

if it is unable to get the instance

Returns the singleton instance of the OpenVR event manager, creating it if it doesn't already exist. This method is called by the VR driver during initialization.

References de(), and makVrv::DtVirtualRealityEventManager::DtVirtualRealityEventManager().

processVrEvents()

virtual void makVrv::DtOpenVREventManager::processVrEvents ( )

overrideprotectedvirtual

Collects and dispatches events from the OpenVR system.

Polls the OpenVR API for controller state updates, processes button and analog input events, and dispatches them to registered event processors.

Note

This method is called by the DtVirtualRealityDriver during the update cycle and is not intended to be called directly by users.

Implements makVrv::DtVirtualRealityEventManager.

updateControllerState()

virtual void makVrv::DtOpenVREventManager::updateControllerState ( DtVirtualRealityControllerState::ControllerId deviceId, DtVirtualRealityControllerState & state )

protectedvirtual

Updates controller state for a specific controller.

Parameters

deviceId	The controller identifier to update
state	Reference to the controller state to update

Updates the provided controller state object with the latest data from the OpenVR controller with the specified device ID. This includes position, orientation, button states, and analog input values.

findDeviceType()

virtual DtVirtualRealityControllerState::Bitfield makVrv::DtOpenVREventManager::findDeviceType ( DtVirtualRealityControllerState::ControllerId deviceId ) const

protectedvirtual

Determines the device type for a given controller ID.

Parameters

deviceId

The controller identifier to query

Returns

Bitfield representing the device type

Maps an OpenVR-specific device identifier to the common controller device type enumeration used throughout the application.

Member Data Documentation

myVrSystem

vr::IVRSystem* makVrv::DtOpenVREventManager::myVrSystem

protected

Pointer to the OpenVR system interface.

This pointer is used to communicate with the OpenVR API for retrieving controller state information and processing events.
