Ich bin ein neues Audio-System für mein Spiel zu schreiben, und ich habe über diesen Fehler kam und kann nicht überall zu finden und Lösung scheint,Fehler beim Laden der Audio-in Java (illegal call() in der Schnittstelle Clip zu öffnen)
java.lang.IllegalArgumentException: illegal call to open() in interface Clip
at com.sun.media.sound.DirectAudioDevice$DirectClip.implOpen(Unknown Source)
at com.sun.media.sound.AbstractDataLine.open(Unknown Source)
at com.sun.media.sound.AbstractDataLine.open(Unknown Source)
Dies ist der Code, den ich verwende, um meine Audiodaten zu laden und abzuspielen.
private Clip load(String filename) {
try {
//Loads the file
InputStream in = new FileInputStream(new File("res/" + filename + FILE_EXT));
//Create the input buffer
InputStream bufferedIn = new BufferedInputStream(in);
//Convert into an audio stream
AudioInputStream audioStream = AudioSystem.getAudioInputStream(bufferedIn);
//Get the audio format
AudioFormat format = audioStream.getFormat();
//Get the data line info
DataLine.Info info = new DataLine.Info(Clip.class, format);
//Return the clip
Clip audioClip = (Clip) AudioSystem.getLine(info);
audioClip.addLineListener(this);
return this.clip = audioClip;
} catch (FileNotFoundException e) {
System.err.println("Failed to load audio! " + filename + " not found!");
throw new RuntimeException(e);
} catch (UnsupportedAudioFileException e) {
System.err.println("Failed to load audio! " + filename + " is unsupported!");
throw new RuntimeException(e);
} catch (IOException e) {
System.err.println("Failed to load audio! " + filename + " caused an IO Exception!");
throw new RuntimeException(e);
} catch (LineUnavailableException e) {
System.err.println("Failed to load audio! " + filename + " line is unavalible!");
e.printStackTrace();
}
throw new RuntimeException("Failed to load audio! input == null!");
}
private void startClip() {
if(this.clip != null) this.clip.start();
else throw new RuntimeException("Failed to start audio clip! The clip appears to be null.");
}
private void stopClip() {
if(this.clip != null) this.clip.close();
else throw new RuntimeException("Failed to close audio clip! The clip appears to be null.");
}
@Override
public void play() {
try {
if(isPlaying()) return;
else {
startClip();
this.clip.open();
this.playing = true;
}
} catch (LineUnavailableException e) {
e.printStackTrace();
}
}
Der Fehler tritt bei this.clip.open();
Kann mir jemand helfen?
