public interface KeyStrokeListenerRegistration

Eine Schnittstelle zum An- und Abmelden von Beobachtern, die auf die gedrückte Tasten reagieren.

Method Summary

Modifier and Type	Method	Description
default void	addKeyStrokeListener(KeyStrokeListener listener)	Fügt einen statisch KeyStrokeListener hinzu, d. h. dieser KeyStrokeListener gilt global über das ganze Spiel und ist unabhängig von der aktuellen Szene.
EventListeners<KeyStrokeListener>	keyStrokeListeners()
default void	removeKeyStrokeListener(KeyStrokeListener listener)	Entfernt einen KeyStrokeListener vom Objekt.

Method Details

keyStrokeListeners

EventListeners<KeyStrokeListener> keyStrokeListeners()

addKeyStrokeListener

@API
default void addKeyStrokeListener(KeyStrokeListener listener)

Fügt einen statisch KeyStrokeListener hinzu, d. h. dieser KeyStrokeListener gilt global über das ganze Spiel und ist unabhängig von der aktuellen Szene.

Der KeyStrokeListener kann auf mehrere Arten implementiert werden:

1. Als normale Klasse:

   
    class MyKeyStrokelistener implements KeyStrokeListener
    {
        @Override
        public void onKeyDown(KeyEvent e)
        {
            // Code here
        }
    }
    obj.addKeyStrokeListener(new MyKeyStrokelistener());
    

2. Als anonyme Klasse:

   
    obj.addKeyStrokeListener(new KeyStrokeListener()
    {
        @Override
        public void onKeyDown(KeyEvent e)
        {
            // Code here
        }
    });
    

3. Oder als Lambda-Ausdruck:

   
    obj.addKeyStrokeListener(e -> {
        // Code here
    });
    

Parameters:

listener - Ein Objekt der Klasse KeyStrokeListener.

removeKeyStrokeListener

@API
default void removeKeyStrokeListener(KeyStrokeListener listener)

Entfernt einen KeyStrokeListener vom Objekt.

Parameters:

listener - Ein Objekt der Klasse KeyStrokeListener.
