Member Function Documentation

AcceptsInput()

bool CJoystickFeature::AcceptsInput

(

bool

bActivation

)

Check if the input handler is accepting input.

Parameters

bActivation

True if the motion is activating (true or positive), false if the motion is deactivating (false or zero)

Returns

True if input should be sent to the input handler, false otherwise

InMotion()

bool CJoystickFeature::InMotion ( ) const

protected

Check if the feature is in motion.

MotionTimeMs()

unsigned int CJoystickFeature::MotionTimeMs ( ) const

protected

Get the time for which the feature has been in motion.

OnAnalogMotion()

virtual bool KODI::JOYSTICK::CJoystickFeature::OnAnalogMotion ( const CDriverPrimitive & source, float magnitude )

pure virtual

An analog motion has occurred.

Parameters

source	The source of the motion. Must be a semiaxis
magnitude	The magnitude of the press or motion in the interval [0.0, 1.0]

For semiaxes, the magnitude is the force or travel distance in the direction of the semiaxis. If the value is in the opposite direction, the magnitude is 0.0.

For example, if the analog stick goes left, the negative semiaxis will have a value of 1.0 and the positive semiaxis will have a value of 0.0.

Implemented in KODI::JOYSTICK::CAccelerometer, KODI::JOYSTICK::CAnalogStick, KODI::JOYSTICK::CScalarFeature, KODI::JOYSTICK::CThrottle, and KODI::JOYSTICK::CWheel.

OnDigitalMotion()

virtual bool KODI::JOYSTICK::CJoystickFeature::OnDigitalMotion ( const CDriverPrimitive & source, bool bPressed )

pure virtual

A digital motion has occurred.

Parameters

source	The source of the motion. Must be digital (button or hat)
bPressed	True for press motion, false for release motion

Returns

true if the motion was handled, false otherwise

Implemented in KODI::JOYSTICK::CAccelerometer, KODI::JOYSTICK::CAnalogStick, KODI::JOYSTICK::CAxisFeature, and KODI::JOYSTICK::CScalarFeature.

ProcessMotions()

virtual void KODI::JOYSTICK::CJoystickFeature::ProcessMotions ( void )

pure virtual

Process the motions that have occurred since the last invocation.

This allows features with motion on multiple driver primitives to call their handler once all driver primitives are accounted for.

Implemented in KODI::JOYSTICK::CAccelerometer, KODI::JOYSTICK::CAnalogStick, KODI::JOYSTICK::CAxisFeature, and KODI::JOYSTICK::CScalarFeature.

ResetMotion()

void CJoystickFeature::ResetMotion ( )

protected

Reset motion timer.

StartMotion()

void CJoystickFeature::StartMotion ( )

protected

Start the motion timer.
