Hallo liebe Com,
ich probiere mich gerade ein wenig an dem Tutorial für Spiele Programmierung in Java von Quaxli.
Dabei wende ich aber seine Hilfen nur an und schreibe dementsprechend nicht genau an dem Spiel, welches er beschreibt.Momentan hänge ich jedoch daran,das ich versuche den Hintergrund mit vielen kleinen Bildplatten zu füllen.Dafür habe ich eine neue Klasse erstellt:
Ausserdem gibt es eine Klasse Background
An und für sich bekomme ich keine Fehlermeldungen oder ähnliches.mein Problem ist nur,das ich beim Ausführen keine Bilder angezeigt bekomme.Irgendetwas muss er aber laden, da je nachdem an welcher Position(Ebene) ich etwas zeichnen lasse nichts zu sehen ist, oder wenigstens die Spielfigur.
Hier noch das Game Panel:
Vielen Dank schonmal für eure Hilfe und Liebe Grüße Kooki
