public class WandViewBehavior.TranslationListener2D extends WandViewBehavior.ListenerBase
Implements a 2D valuator listener that translates the view platform. The X and Y values from the valuator should have a continuous range from -1.0 to +1.0, although the translation 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 bysetMatrixIndices2D
, with defaults of 3 and 7 respectively.The translation direction is controlled by the direction the 2D valuator is pushed, and the speed is the translation speed scaled by the fast speed factor and the magnitude of the 2D valuator reads.
This listener will work in conjunction with a 6DOF sensor if supplied in the constructor. If a 6DOF sensor is provided then the translation occurs along the basis vectors of the 6DOF sensor's coordinate system; otherwise, the translation occurs along the view platform's basis vectors.

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 frompressed
or when a 2D valuator exits the deadzone threshold.- Overrides:
initAction
in classWandViewBehavior.ListenerBase
- Parameters:
s
- reference to a 6DOF sensor if used by the listener; may benull
-
endAction
protected void endAction(Sensor s)
Description copied from class:WandViewBehavior.ListenerBase
Ends the action. Subclasses must be call this fromreleased
or when a 2D valuator enters the deadzone threshold.- Overrides:
endAction
in classWandViewBehavior.ListenerBase
- Parameters:
s
- reference to a 6DOF sensor if used by the listener; may benull
-
read
public void read(SensorEvent e)
Description copied from interface:SensorReadListener
This method is called each time thedispatchEvents
method ofSensorEventAgent
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 interfaceSensorReadListener
- Overrides:
read
in classSensorInputAdaptor
- 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 interfaceSensorButtonListener
- Overrides:
pressed
in classWandViewBehavior.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 interfaceSensorButtonListener
- Overrides:
released
in classWandViewBehavior.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 thedispatchEvents
method ofSensorEventAgent
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 interfaceSensorButtonListener
- Overrides:
dragged
in classSensorInputAdaptor
- Parameters:
e
- the sensor event
