如何在按下特定的键时播放声音

Question

我正在尝试创建一个鼓小程序。所以鼓的每个部分在键盘上都有相应的键，如果你按下它，就会发出声音。如何使用按键播放声音?

Answer 1

好的。所以你需要不同架子鼓声音的样本，例如。Kick, Snare, Hihat, crash等。最好是用.wav格式。所以你要做的是使用Event Handling，当一个键被按下时播放相应的音频。确保所有的音频样本都在当前项目所在的目录中。尽管写代码和做作业并不是这里要遵循的策略，我还是会写一个结构来给你解释。

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
public class DrumApplet extends Applet implements KeyListener{
    //declaring Audio variables
    AudioClip kick, snare, hat_close, hat_opem, crash, tom;
    @Override
    public void init(){
        kick = this.getAudioClip(getDocumentBase(), "kick.wav");
        snare = this.getAudioClip(getDocumentBase(), "snare.wav");
        //load all other audio samples
        addKeyListener(this); //to detect the press of a key
    }
    @Override
    public void paint(Graphics g){
        //display message as to which key to press to play a sound
    }
    @Override
    public void keyPressed(KeyEvent K){
        char X = K.getKeyCode();
        if(X == 'K')
        kick.play(); //play kick.wav when K is pressed
        if(X == 'S')
        snare.play(); //play snare.wav when S is pressed
        if(X == 'T')
        tom.play(); //play tom.wav when T is pressed
        if(X == 'O')
        hat_open.play(); //play hat_open.wav when O is pressed
        //write if statements for the rest of the Keys
        repaint();
    }
    @Override
    public void keyReleased(KeyEvent K){}
    @Override
    public void keyTyped(KeyEvent K){}
}
