- initialize
  
  public void initialize()
  
  Description copied from class: Behavior
  
  Initialize this behavior. Classes that extend Behavior must provide their own initialize method.
  NOTE: Applications should not call this method. It is called by the Java 3D behavior scheduler.
  
  Specified by:
  
  initialize in class Behavior
- processStimulus
  
  public void processStimulus(Enumeration criteria)
  
  Description copied from class: Behavior
  
  Process a stimulus meant for this behavior. This method is invoked if the Behavior's wakeup criteria are satisfied and an active ViewPlatform's activation volume intersects with the Behavior's scheduling region. Classes that extend Behavior must provide their own processStimulus method.
  NOTE: Applications should not call this method. It is called by the Java 3D behavior scheduler.
  
  Specified by:
  
  processStimulus in class Behavior
  
  Parameters:
  
  criteria - an enumeration of triggered wakeup criteria for this behavior
- updateScene
  
  public abstract void updateScene(int xpos, int ypos)
