Also ich bin ziemlich neu in Java und ich baute dieses Board für ein Snake-Spiel mit einem tutorial. Es scheint gut zu funktionieren, außer dass die Bilddateien nicht geladen werden. Ich habe noch nicht mit Bildern in Eclipse gearbeitet, daher weiß ich nicht wirklich, was ich mache. Ich habe versucht, die .png Bilddateien in das Paket zu packen, aber das hat mir überhaupt nicht geholfen. Ich würde mich über irgendwelche Ideen freuen.Bilddateien laden nicht in 2D Java-Spiel

Debug Ihre Anwendung. Erhalten Sie in 'loadImages()' eine gültige ImageIcon, wenn Sie Ihre Bilder laden?Wenn nicht, kann das Bild nicht am Pfad gefunden werden. Versuchen Sie, den vollständigen Pfad zum Bild anzugeben, z. B. "C: \\ Entwicklung \\ Spiel \\ head.png" '. – Frecklefoot
