Public Member Functions
void	GetDeviceList (ezHybridArray< ezXRDeviceID, 64 > &out_devices) const override
	Fills out a list of valid (connected) device IDs.
ezXRDeviceID	GetDeviceIDByType (ezXRDeviceType::Enum type) const override
	Returns the deviceID for a specific type of device. If the device is not connected, -1 is returned instead.
const ezXRDeviceState &	GetDeviceState (ezXRDeviceID deviceID) const override
	Returns the current device state for a valid device ID.
ezString	GetDeviceName (ezXRDeviceID deviceID) const override
	Returns the device name for a valid device ID. More...
ezBitflags< ezXRDeviceFeatures >	GetDeviceFeatures (ezXRDeviceID deviceID) const override
	Returns the device features for a valid device ID.
Public Member Functions inherited from ezXRInputDevice
const ezXRDeviceEvent &	GetInputEvent ()
	Returns the input event. Allows tracking device addition and removal.
Public Member Functions inherited from ezInputDevice
	ezInputDevice ()
	Default Constructor.
float	GetInputSlotState (ezStringView sSlot) const
	Allows to query current input values for the given slot.
bool	HasDeviceBeenUsedLastFrame () const
	Returns true, if the device was 'used' during the last frame, ie. when it generated input due to some user interaction. More...
Public Member Functions inherited from ezReflectedClass
virtual const ezRTTI *	GetDynamicRTTI () const
bool	IsInstanceOf (const ezRTTI *pType) const
	Returns whether the type of this instance is of the given type or derived from it.
template<typename T >
EZ_ALWAYS_INLINE bool	IsInstanceOf () const
	Returns whether the type of this instance is of the given type or derived from it.

Protected Member Functions
void	InitializeDevice () override
	Override this if you need to do device specific initialization before the first use.
void	UpdateInputSlotValues () override
	Override this, if you need to query the state of the hardware to update the input slots. More...
void	RegisterInputSlots () override
	Override this to register all the input slots that this device exposes. More...
Protected Member Functions inherited from ezInputDevice
virtual void	ResetInputSlotValues ()
	Override this, if you need to reset certain input slot values to zero, after the ezInputManager is finished with the current frame update.
virtual void	UpdateHardwareState (ezTime tTimeDifference)
	This function is called once after ezInputManager::Update with the same time delta value. It allows to update hardware state, such as the vibration of gamepad motors.

Protected Attributes

ezMap< ezString, float >	m_InputSlotValues
	Stores all the values for all input slots that this device handles. More...
ezUInt32	m_uiLastCharacter
	If this input device type handles character input, it should write the last typed character into this variable. The ezInputManager calls RetrieveLastCharacter() to query what the user typed last.

Member Function Documentation

GetDeviceName()

ezString ezDummyXRInput::GetDeviceName ( ezXRDeviceID  deviceID ) const

overridevirtual

Returns the device name for a valid device ID.

This returns a human readable name to identify the device. For ezXRDeviceType::HMD the name is always 'HMD'. This can be used for e.g. controllers to create custom game input logic or mappings if a certain type of controller is used. Values could be for example: 'Simple Controller', 'Mixed Reality Motion Controller', 'Hand Interaction' etc.

Implements ezXRInputDevice.

RegisterInputSlots()

void ezDummyXRInput::RegisterInputSlots ( )

overrideprotectedvirtual

Override this to register all the input slots that this device exposes.

This is called once during initialization. It needs to call RegisterInputSlot() once for every input slot that this device exposes to the system.

Implements ezInputDevice.

UpdateInputSlotValues()

void ezDummyXRInput::UpdateInputSlotValues ( )

overrideprotectedvirtual

Override this, if you need to query the state of the hardware to update the input slots.

Note

This function might be called multiple times before ResetInputSlotValues() is called. This will be the case when ezInputManager::PollHardware is used to make more frequent hardware updates than input is actually processed. Just make sure to always accumulate delta values (such as mouse move values) and don't expect ResetInputSlotValues() to be called in tandem with this function and it will be fine.
