public class PlayerKeyNavigator

extends KeyNavigatorEx

This is the KeyNavigator class. It accumulates AWT key events (key press and key release) and computes a new transform based on the accumulated events and elapsed time. The most code of the integrateTransformChanges method was taken from the KeyNavigator class provided by Sun.

Constructor Detail

PlayerKeyNavigator

public PlayerKeyNavigator(Player cPlayer,
                          javax.media.j3d.TransformGroup targetTG)

Constructs a new key navigator object that operates on the specified transform group. All parameters are set to their default, idle state.

Parameters:

targetTG - the target transform group

Method Detail

integrateTransformChanges

public void integrateTransformChanges()

Computes a new transform for the next frame based on the current transform, accumulated keyboard inputs, and elapsed time. This new transform is written into the target transform group. This method should be called once per frame.

Overrides:

integrateTransformChanges in class KeyNavigatorEx

processKeyEvent

public void processKeyEvent(java.awt.event.KeyEvent keyEvent)

Processed a keyboard event. This routine should be called every time a KEY_PRESSED or KEY_RELEASED event is received.

Parameters:

keyEvent - the AWT key event

Overrides:
