java中的音效
java中的音效
提问于 2013-12-03 22:58:51
当我的太空船发射一颗子弹时，我一直在试着得到一个简单的"pew“声音。声音是我保存在netbeans项目的主文件夹中的.wav文件。
当我运行代码时，我没有得到任何错误，只是它不能播放声音。
在Main.java中，当鼠标被按下时，它会发射一颗子弹，并且应该会播放声音。Sound.java可以在下面找到。
Main.java
@Override
public void mousePressed(MouseEvent me) {
Color color = Color.yellow;
if(tankMissile == null){
tankMissile = new Missile(launcher.getXofMissileShoot(), launcher.getYofMissileShoot(), color);
tankMissile.setTarget(launcher.x, 0);
int size = 2;
tankMissile.setExplosionMaxSize(size);
synchronized (gameData.figures) {
gameData.figures.add(tankMissile);
}
}
new Sound("pew.wav").start();
}Sound.java
//www.anyexample.com/programming/java/java_play_wav_sound_file.xml
import java.io.*;
import javax.sound.sampled.*;
public class Sound extends Thread{
private String fileName;
public Sound(String wavfile){
fileName = wavfile;
}
@Override
public void run(){
File soundFile = new File(fileName);
if(!soundFile.exists()){
System.err.println("Wave file not found");
}
AudioInputStream audioInputStream = null;
try{
audioInputStream = AudioSystem.getAudioInputStream(soundFile);
}
catch(UnsupportedAudioFileException e){
e.printStackTrace();
return;
}
catch(IOException e){
e.printStackTrace();
return;
}
AudioFormat format = audioInputStream.getFormat();
SourceDataLine auline = null;
DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);
try{
auline = (SourceDataLine) AudioSystem.getLine(info);
auline.open(format);
}
catch(LineUnavailableException e){
e.printStackTrace();
return;
}
catch(Exception e){
e.printStackTrace();
return;
}
if(auline.isControlSupported(FloatControl.Type.PAN)){
FloatControl pan = (FloatControl) auline.getControl(FloatControl.Type.PAN);
}
auline.start();
}
}我终于让它起作用了。这就是我所做的。
Main.java
@Override
public void mousePressed(MouseEvent me) {
Color color = Color.yellow;
if(tankMissile == null){
tankMissile = new Missile(launcher.getXofMissileShoot(), launcher.getYofMissileShoot(), color);
tankMissile.setTarget(launcher.x, 0);
int size = 2;
tankMissile.setExplosionMaxSize(size);
synchronized (gameData.figures) {
gameData.figures.add(tankMissile);
}
try {
playSound("pew.wav");
} catch (MalformedURLException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
} catch (LineUnavailableException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
} catch (UnsupportedAudioFileException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
}
}稍后在Main.java中
public static void playSound(String fileName) throws MalformedURLException, LineUnavailableException, UnsupportedAudioFileException, IOException{
File url = new File(fileName);
Clip clip = AudioSystem.getClip();
AudioInputStream ais = AudioSystem.
getAudioInputStream( url );
clip.open(ais);
clip.start();

您可以使用此方法播放wav格式。你应该少编辑，并与你的代码混在一起。
public static synchronized void playSound(final String url) {
new Thread(new Runnable() {
// The wrapper thread is unnecessary, unless it blocks on the
// Clip finishing; see comments.
public void run() {
try {
Clip clip = AudioSystem.getClip();
AudioInputStream inputStream = AudioSystem.getAudioInputStream(
Main.class.getResourceAsStream("/path/to/sounds/" + url));
clip.open(inputStream);
clip.start();
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
}).start();
