public class WandViewBehavior.RotationListener2D
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
.

WandViewBehavior.RotationListener2D(Sensor sensor2D,

Construct an instance of this class with the specified sensors. |
Method Summary | |
---|---|
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. |
