Constructor Detail

KeyNavigator

public KeyNavigator(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.


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
