Controller::HandleInteractionEvent

Called to handle an event for an interactive node.

virtual void HandleInteractionEvent(EventType type, const Point3D *position, Node *initiator = nullptr);

type	The event type. See the list of possible events below.
position	The position, in the target node's local coordinate system, where the event occurred.
initiator	The node that caused the event to occur.

The HandleInteractionEvent function is called when an event needs to be handled for an interactive node. The type parameter specifies the type of event that occurred and can be one of the following constants.

kEventInteractionEngage	The user has begun looking at an interactive object.
kEventInteractionDisengage	The user has stopped looking at an interactive object.
kEventInteractionActivate	The user has explicitly activated an interactive object (e.g., with a mouse click).
kEventInteractionDeactivate	The user has released the input control used to activate an interactive object.
kEventInteractionTrack	The user has changed the interaction position.

By default, a controller activates itself when the kEventInteractionActivate event is received, and no action is taken for other types of events.
