Functions

	Name	Description
void	DisableMotionTrackingForComponent ( const UMotionControllerComponent&#... )	Disable tracking of the specified controller, by player index and tracked device type.
void	DisableMotionTrackingOfAllControllers()	Disable tracking for all controllers.
void	DisableMotionTrackingOfControllersForPlayer ( int32 PlayerIndex )	Disable tracking for all controllers associated with the specified player.
void	DisableMotionTrackingOfDevice ( int32 PlayerIndex, EControllerHand Hand )	Disable tracking of the specified controller, by player index and tracked device type.
void	DisableMotionTrackingOfSource ( int32 PlayerIndex, FName SourceName )	Disable tracking of the specified controller, by player index and tracked device type.
bool	EnableMotionTrackingForComponent ( UMotionControllerComponent* Mo... )	Enable tracking of the specified controller, by player index and tracked device type.
bool	EnableMotionTrackingOfDevice ( int32 PlayerIndex, EControllerHand Hand )	Enable tracking of the specified controller, by player index and tracked device type.
bool	EnableMotionTrackingOfSource ( int32 PlayerIndex, FName SourceName )	Enable tracking of the specified controller, by player index and tracked device type.
TArray< FNam...	EnumerateMotionSources()	Returns a list of all available motion sources (FNames associated with discrete tracking data that can be used to drive MotionControllerComponents).
FName	GetActiveTrackingSystemName()	Returns the system name used to distinguish the current tracking system.
int32	GetMaximumMotionTrackedControllerCount()	Get the maximum number of controllers that can be tracked.
int32	GetMotionTrackingEnabledControllerCount()	Get the number of controllers for which tracking is enabled.
bool	IsMotionSourceTracking ( int32 PlayerIndex, FName SourceName )	Queries the specified source's tracking status and returns true if it has tracking.
bool	IsMotionTrackedDeviceCountManagementNecessary()	Returns true if it is necessary for the game to manage how many motion tracked devices it is asking to be tracked simultaneously.
bool	IsMotionTrackingEnabledForComponent ( const UMotionControllerComponent&#... )	Returns true if tracking is enabled for the specified device.
bool	IsMotionTrackingEnabledForDevice ( int32 PlayerIndex, EControllerHand Hand )	Returns true if tracking is enabled for the specified device.
bool	IsMotionTrackingEnabledForSource ( int32 PlayerIndex, FName SourceName )	Returns true if tracking is enabled for the specified device.
void	SetIsControllerMotionTrackingEnabledByDefault ( bool Enable )	Set whether motion tracked controllers activate on creation by default, or do not and must be explicitly activated.
