Posts: 1988. Posted: Sun Apr 06, 2003 1:05 am I am working on a game using only the swing and awt packages. Note I can only use the default Java libs. Meaning I have to use KeyListener. I have imported KeyListener properly, however, it is still relatively buggy. Here is a snippet of my code. p is for Player class, I am going to set x and y to private, however, this is for simplicity Java WindowListener Interface.
Bonjour, Je suis un grand débutant en programmation Java et actuellement je suis en train de créer le jeux du Ping-Pong pour m'entraîner, seulement quand j'utilise mon KeyListener pour déplacer les raquettes droite ou gauche (oui car c'est un jeux deux joueurs sur le même clavier) il y à un problème.
public interface KeyListener extends EventListener The listener interface for receiving keyboard events (keystrokes). The class that is interested in processing a keyboard event either implements this interface (and all the methods it contains) or extends the abstract KeyAdapter class (overriding only the methods of interest). Čau, lidi.

AwtListenerDemo.java To handle low-level events, the java.awt.event package comes with three listeners – MouseListener (with 3 abstract methods), MouseMotionListener (with 2 abstract methods) and KeyListener (with 3 abstract methods).

The class that is interested in processing a keyboard event either implements this interface (and all the methods it contains) or extends the abstract KeyAdapter class (overriding only the methods of interest). Čau, lidi. Potřeboval bych vědět jak můžu přidat KeyListener celé aplikaci, ale výstup z KeyListeneru chci jen do jednoho componentu, kterej sem si vytvořil. Když sem přidal Keylistener do hlavní třídy, tak to nic nedělalo a když jsem si vytvořil novej JPanel, do kterýho sem vložil všechny komponenty, a přidal jsem mu KeyListener, tak to taky nedělalo nic.
You don't add KeyListeners with add() but rather with addKeyListener() since add() is for adding component only, but having said that, I wouldn't even use a KeyListener for this but rather Key Bindings which would help to fix the problems you will have in the future when focus prevents your KeyListener from working. The Java Tutorials have been written for JDK 8. Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available.

You need to read the tutorials first. You don't add KeyListeners with add() but rather with addKeyListener() since add() is for adding component only, but having said that, I wouldn't even use a KeyListener for this but rather Key Bindings which would help to fix the problems you will have in the future when focus prevents your KeyListener from working.
The event is passed to every KeyListener or KeyAdapter object which registered to receive such events using the component's addKeyListener method.
