All Implemented Interfaces:

SensorButtonListener, SensorReadListener

Enclosing class:

WandViewBehavior

public class WandViewBehavior.RotationListener2D
extends WandViewBehavior.ListenerBase

Implements a 2D valuator listener that rotates the view platform. The X and Y values from the valuator should have a continuous range from -1.0 to +1.0, although the rotation speed can be scaled to compensate for a different range. The X and Y values are found in the sensor's read matrix at the indices specified by setMatrixIndices2D, with defaults of 3 and 7 respectively.

The rotation direction is controlled by the direction the 2D valuator is pushed, and the rotation speed is scaled by the magnitude of the 2D valuator read values.

This listener will work in conjunction with a 6DOF sensor if supplied in the constructor. If a 6DOF sensor is provided and setRotationCoords has been called with the value SENSOR, then the rotation is applied in the 6DOF sensor's coordinate system; otherwise the rotation is applied either in head coordinates or in view platform coordinates. If a 6DOF sensor is provided and setTransformCenterSource has been called with the value HOTSPOT, then rotation is about the 6DOF sensor's hotspot; otherwise, the rotation center is the value set by setTransformCenter.

Constructor Summary

Constructors

Constructor and Description
RotationListener2D(Sensor sensor2D, Sensor sensor6D) Construct an instance of this class with the specified sensors.

Method Summary

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.
void	pressed(SensorEvent e) This method is called when a sensor's button is pressed.
void	read(SensorEvent e) This method is called each time the dispatchEvents method of SensorEventAgent is called and none of a sensor's buttons have been handled by a button listener.
void	released(SensorEvent e) This method is called when a sensor's button is released.

Constructor Detail

RotationListener2D

public RotationListener2D(Sensor sensor2D,
                          Sensor sensor6D)

Construct an instance of this class with the specified sensors.

Parameters:

sensor2D - the 2D valuator whose X and Y values drive the rotation

sensor6D - the 6DOF sensor to use if the rotation coordinate system is set to SENSOR or the rotation center source is HOTSPOT; may be null

Method Detail

read

public void read(SensorEvent e)

Description copied from interface: SensorReadListener

This method is called each time the dispatchEvents method of SensorEventAgent is called and none of a sensor's buttons have been handled by a button listener. The sensor read value has not necessarily changed since the last read event.

Specified by:

read in interface SensorReadListener

Overrides:

read in class SensorInputAdaptor

Parameters:

e - the sensor event

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

released

public void released(SensorEvent e)

Description copied from interface: SensorButtonListener

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

Specified by:

released in interface SensorButtonListener

Overrides:

released 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
