public class KeyBehavior
extends javax.media.j3d.Behavior

This class is a simple behavior that implements keyboard navigation. It is meant to modify the view platform transform. Other than the classes KeyNavigatorBehavior and KeyNavigator from SUN this class needs less computing power and is restricted to a few keys with no acceleration. The following keys are used:

Up arrow - to move forward.

Down arrow - to move backwards.

Left arrow - to turn left.

Right arrow - to turn right.

Page up - to look up.

Page down - to look down.

Y - to strafe left.

X - to strafe right.

Constructor Detail

KeyBehavior

public KeyBehavior(javax.media.j3d.TransformGroup targetTG)

Constructs a new key navigator behavior node that operates on the specified transform group.

Parameters:

targetTG - the target transform group

Method Detail

initialize

public void initialize()

Override Behavior's initialize method to setup wakeup criteria.

Specified by:

initialize in class javax.media.j3d.Behavior

processStimulus

public void processStimulus(java.util.Enumeration criteria)

Override Behavior's stimulus method to handle the event. This method is called when a key on the keyboard has been pressed.

Specified by:

processStimulus in class javax.media.j3d.Behavior

Parameters:

criteria - All pressed keys in a list. This will be passed by the system.
