Hi everyone, i'm trying to make a sound each time a ball touches the lift and right of a frame but when i use clip and try to use the sound class it sound from right then left the in middle and then stop. i Can really use some help. The code is down below..
package basics;
import java.awt.*;
import java.util.Formatter;
import javax.swing.*;
import java.io.File;
import java.io.IOException;
import javax.sound.sampled.*;
import java.awt.Toolkit;
// Extends JPanel, so as to override the paintComponent() for custom rendering codes.
public class MovingLeftRight extends JPanel {
// Container box's width and height
private static final int BOX_WIDTH = 640;
private static final int BOX_HEIGHT = 480;
private Clip clip;
// Ball's properties
private float ballRadius = 50; // Ball's radius
private float ballX =250- ballRadius ; // Ball's center (x, y)
private float ballY = 250-ballRadius;
private float ballSpeedX = 7; // Ball's speed for x and y
//private float ballSpeedY = 2;
private static final int UPDATE_RATE = 30; // Number of refresh per second
/** Constructor to create the UI components and init game objects. */
public MovingLeftRight() {
super();
this.setPreferredSize(new Dimension(BOX_WIDTH, BOX_HEIGHT));
// Start the ball bouncing (in its own thread)
Thread gameThread = new Thread() {
public void run() {
try {
// Open an audio input stream.
File soundFile = new File("resources/snd16.wav");
// Get a sound clip resource.
Clip clip = AudioSystem.getClip();
// Open audio clip and load samples from the audio input stream.
AudioInputStream audioIn = AudioSystem.getAudioInputStream(soundFile);
clip.open(audioIn);
while (true) { // Execute one update step
// Calculate the ball's new position
ballX += ballSpeedX;
// Check if the ball moves over the bounds
// If so, adjust the position and speed.
if (ballX - ballRadius < 0) {
ballSpeedX = -ballSpeedX; // Reflect along normal
ballX = ballRadius; // Re-position the ball at the edge
clip.start();
//Toolkit.getDefaultToolkit().beep();
clip.loop(4);
// Sounds.reproduceSound(Sounds.PING);
} else if (ballX + ballRadius > BOX_WIDTH) {
ballSpeedX = -ballSpeedX;
ballX = BOX_WIDTH - ballRadius;
//clip.setLoopPoints(0, 1);
clip.start();
//Toolkit.getDefaultToolkit().beep();
}
// Refresh the display
repaint(); // Callback paintComponent()
// Delay for timing control and give other threads a chance
try {
Thread.sleep(1000 / UPDATE_RATE); // milliseconds
} catch (InterruptedException ex) { }
}
} catch (UnsupportedAudioFileException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();

e.printStackTrace();
}

}
};

}
/** Custom rendering codes for drawing the JPanel */

public void paintComponent(Graphics g) {
super.paintComponent(g); // Paint background
// Draw the box

g.fillRect(0, 0, BOX_WIDTH, BOX_HEIGHT);
// Draw the ball
g.setColor(Color.GREEN);
g.fillOval((int) (ballX - ballRadius), (int) (ballY - ballRadius),

// Display the ball's information
