My sound in my game will only play if a folder titled res is in the same directory as the .jar file. The res folder is already a source folder in the .jar file here is my code
try {
InputStream defaultSound = Game.class.getResourceAsStream("/res/TrailsGameMusic.wav");
// getClass().getSy.getResource("/images/ads/WindowsNavigationStart.wav");
System.out.println("defaultSound " + defaultSound); // check the URL!
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(defaultSound);
Clip clip = AudioSystem.getClip();
clip.open(audioInputStream);
clip.loop(Clip.LOOP_CONTINUOUSLY);
} catch (Exception ex) {
ex.printStackTrace();
}
