Q3Controller_MoveTrackerPosition

You can use the Q3Controller_MoveTrackerPosition function to move a controller's tracker relative to its current position.

TQ3Status Q3Controller_MoveTrackerPosition (
TQ3ControllerRef controllerRef, 
const TQ3Vector3D *delta);

controllerRef

A reference to a controller.

delta

A three-dimensional vector specifying a relative change in the position of the tracker associated with the specified controller.

DESCRIPTION

The Q3Controller_MoveTrackerPosition function changes the position of the tracker currently associated with the controller specified by the controllerRef parameter by the relative amount specified in the delta parameter. If no tracker is currently associated with that controller, Q3Controller_MoveTrackerPosition changes the position of the system cursor's tracker relative to its current position. Q3Controller_MoveTrackerPosition has no effect if the controller is inactive.

Note

Calling Q3Controller_MoveTrackerPosition might cause the notify function of the controller's tracker to be called.
