Hi Leute,
Ich habe Snake geklont und möchte gerne, dass sich zunächst ein Menu-Fenster öffnet, wenn das Programm startet. Im Menu sollen verschiedene Buttons sein, mit denen man z.B. das Spiel starten, die Spielanleitung oder die Highscores einsehen kann. Das Menüpanel habe ich bereits erstellt. Wenn ich den Button "play" anklicke erscheint das JPanel "board", auf dem das Spiel stattfindet und das Menu verschwindet. Allerdings lässt sich die Snake nicht lenken und reagiert auf nichts. Liegt es eventuell daran, dass das JPanel keinen Focus hat? Ich habe schon probiert den Focus auf das board zu bekommen, jedoch ohne Erfolg. Vielleicht liegt der Fehler ja auch ganz wo anders?
Ich bin für jeden Tipp dankbar!
Hier ist die Klasse "Snake":
Das ist die Klasse Frame:
Das ist die Klasse Menu:
Und hier ist die Klasse Board (Ich weiss, die Klasse ist ziemlich umfangreich. Ich denke nicht, dass hier der Fehler liegt, nur um auf Nummer sicher zu gehen stelle ich sie hier vollständig ein.

. Separate Klassen für die spawnenden Objekte habe ich schon versucht umzusetzen, dann schaue ich mir das genauer an und versuche es nochmal. Danke!
