KODI::UTILS::MOVING_SPEED::CMovingSpeed Class Reference

Class to calculate the velocity for a motion effect. To ensure it works, the GetUpdatedDistance method must be called at each input received (e.g. continuous key press of same key on the keyboard). The motion effect will stop at the event ID change (different key pressed). More...

AddEventConfig() [1/2]

void KODI::UTILS::MOVING_SPEED::CMovingSpeed::AddEventConfig	(	uint32_t	eventId,
		EventCfg	event )

Add the configuration for an event.

Parameters

eventId	The id for the event, must be unique
event	The event configuration

AddEventConfig() [2/2]

void KODI::UTILS::MOVING_SPEED::CMovingSpeed::AddEventConfig	(	uint32_t	eventId,
		float	acceleration,
		float	maxVelocity,
		uint32_t	resetTimeout )

Add the configuration for an event.

Parameters

eventId	The id for the event, must be unique
acceleration	Acceleration in pixels per second (px/sec)
maxVelocity	Max movement speed, it depends from acceleration value, a suitable value could be (acceleration value)*3. Set 0 to disable it
resetTimeout	Resets acceleration speed if idle for specified millisecs
