Bonjour,

j'écris un jeu de tennis de table (tel que Pong) en Java avec Swing.
Le but pour l'instant n'est que de déplacer deux raquettes verticalement (la balle et le filet ne sont pas encore présents).
Je dessine sur une JFrame.
Pour cela, je redéfinis la méthode paint(Graphics g).

La première solution sans aucun appel à la méthode repaint pose le problème que la fenêtre n'est pas redessinée lorsque je déplace les raquettes (en fait elle est redessinée seulement lorsqu'on la cache puis qu'on l'affiche à nouveau).

La deuxième solution avec repaint à chaque événement pose le problème de clignotement (probablement car trop d'appels à repaint sont effectués) mais résoud le problème que la fenêtre n'était pas redessinée.

La troisième solution avec repaint toutes les 60ms pose le problème de clignotement (probablement car trop d'appels à repaint sont effectués) mais résoud le problème que la fenêtre n'était pas redessinée. Si on augmente le délai : 200ms alors le problème de clignotement est résolu mais un nouveau problème apparaît : avec 200ms, la fenêtre est redessinée un peu tard (le déplacement des raquettes est saccadé).

Bref, aucune de mes solutions ne me convient.

Est-ce que quelqu'un aurait une solution pour que lorsque je déplace mes raquettes la fenêtre se redéssine correctement?

Merci bien.

Voici le code :
