我正在为一张专辑制作一个小互动广告。它有 4 个可拖动的歌曲标题，当放在目标上时，歌曲开始播放。试图弄清楚当一首新歌开始时如何停止正在播放的歌曲。这是我的代码：
package {
import flash.display.*;
import flash.events.*;
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.net.URLRequest;
public class Deftones extends MovieClip{
function Deftones() {
swerve1.addEventListener(MouseEvent.MOUSE_DOWN, dragStartS);
swerve1.addEventListener(MouseEvent.MOUSE_UP, dragEndS);
polt1.addEventListener(MouseEvent.MOUSE_DOWN, dragStartS);
polt1.addEventListener(MouseEvent.MOUSE_UP, dragEndS);
rd1.addEventListener(MouseEvent.MOUSE_DOWN, dragStartS);
rd1.addEventListener(MouseEvent.MOUSE_UP, dragEndS);
gauze1.addEventListener(MouseEvent.MOUSE_DOWN, dragStartS);
gauze1.addEventListener(MouseEvent.MOUSE_UP, dragEndS);
var sound1:Sound= new Sound();
var sound2:Sound= new Sound();
var sound3:Sound= new Sound();
var sound4:Sound= new Sound();
sound1.load(new URLRequest("music/Swerve_City.mp3"));
sound2.load(new URLRequest("music/Poltergeist.mp3"));
sound3.load(new URLRequest("music/Romantic_Dreams.mp3"));
sound4.load(new URLRequest("music/Gauze.mp3"));
var channel:SoundChannel= new SoundChannel();
function dragStartS(e:MouseEvent){
e.currentTarget.startDrag();
}
function dragEndS(e:MouseEvent){
e.currentTarget.stopDrag();
if (swerve1.hitTestObject(speaker1)){
channel.stop();
sound1.play(0);
}
else if (polt1.hitTestObject(speaker1)){
channel.stop();
sound2.play(0);
}
else if (rd1.hitTestObject(speaker1)){
channel.stop();
sound3.play(0);
}
else if (gauze1.hitTestObject(speaker1)){
channel.stop();
sound4.play(0);
}
}
}
}
任何帮助我都会非常感激。
