All Implemented Interfaces:

SensorButtonListener, SensorReadListener

Enclosing class:

WandViewBehavior

public class WandViewBehavior.RotationListener6D
extends WandViewBehavior.ListenerBase

Implements a 6DOF sensor button listener that rotates the view platform about a Y axis. This axis can be relative to the sensor, user head, or view platform. The rotation center can be the sensor hotspot or a fixed point in virtual world coordinates.

Methods

Modifier and Type	Method and Description
void	dragged(SensorEvent e) This method is called with each invocation of the dispatchEvents method of SensorEventAgent if any button bound to the listener is down and has not changed state since the last invocation.
protected void	endAction(Sensor s) Ends the action.
protected void	initAction(Sensor s) Initializes the listener action.
void	pressed(SensorEvent e) This method is called when a sensor's button is pressed.

Constructor Detail

WandViewBehavior.RotationListener6D

public WandViewBehavior.RotationListener6D(boolean reverse)

Construct a new rotation button listener for a 6DOF sensor.

Parameters:

reverse - if true, rotate clockwise; otherwise, rotate counter-clockwise

Method Detail

initAction

protected void initAction(Sensor s)

Description copied from class: WandViewBehavior.ListenerBase

Initializes the listener action. Subclasses must call this before starting the action, either from pressed or when a 2D valuator exits the deadzone threshold.

Overrides:

initAction in class WandViewBehavior.ListenerBase

Parameters:

s - reference to a 6DOF sensor if used by the listener; may be null

endAction

protected void endAction(Sensor s)

Description copied from class: WandViewBehavior.ListenerBase

Ends the action. Subclasses must be call this from released or when a 2D valuator enters the deadzone threshold.

Overrides:

endAction in class WandViewBehavior.ListenerBase

Parameters:

s - reference to a 6DOF sensor if used by the listener; may be null

pressed

public void pressed(SensorEvent e)

Description copied from interface: SensorButtonListener

This method is called when a sensor's button is pressed.

Specified by:

pressed in interface SensorButtonListener

Overrides:

pressed in class WandViewBehavior.ListenerBase

Parameters:

e - the sensor event

dragged

public void dragged(SensorEvent e)

Description copied from interface: SensorButtonListener

This method is called with each invocation of the dispatchEvents method of SensorEventAgent if any button bound to the listener is down and has not changed state since the last invocation. The sensor value has not necessarily changed from the last drag event.

Specified by:

dragged in interface SensorButtonListener

Overrides:

dragged in class SensorInputAdaptor

Parameters:

e - the sensor event
