mp3 循环问题-Actionscript 3

Question

这太奇怪了，这篇文章不会让我以 hello hi 或 howdy 开头，也许是缓存问题，无论如何，你好，我对 AS3 非常陌生，所以我的知识有限，希望各位专业人士能够轻松地了解新的内容家伙:)。 我正在构建一个带有循环动画的 Flash 网站，并且添加了一首 mp3 歌曲作为背景音乐，它还设置为循环和自动播放。问题是，歌曲比动画长，当动画返回到第一帧时，歌曲与仍在播放的歌曲重叠。我希望这首歌能够在再次开始播放之前完全完成。是的，可能缺少一堆代码，但我已经接近我想要的了，只需要你的帮助来完善它。

这是到目前为止的代码

import flash.events.MouseEvent;
import flash.media.Sound;
import flash.net.URLRequest;

//var codes
var AutoPlay:Boolean=true;
var isPlaying:Boolean=false;
var pausePosition:Number=0;
var myMusic:Sound=new Sound();
var soundFile:URLRequest=new URLRequest("Fluke.mp3");
myMusic.load(soundFile);
var channel:SoundChannel;

//if commands
if (AutoPlay==true) {
channel=myMusic.play(pausePosition);
isPlaying=true;
}

//pausebutton functions
pause_btn.addEventListener(MouseEvent.CLICK, pauseSound);
function pauseSound(e:MouseEvent):void
{
if (isPlaying == false) {
channel = myMusic.play(pausePosition);
isPlaying =true;
}else{
pausePosition=channel.position;
channel.stop();
isPlaying=false;
}
}

//playbutton functions
play_btn.addEventListener(MouseEvent.CLICK,playMus ic);
function playMusic(event:MouseEvent):void
{ if (isPlaying== false) {
channel=myMusic.play(pausePosition);
isPlaying=true;
}
}

这是完整的工作代码，感谢 Josha，我添加了一个 .addEventListener ，以便歌曲在播放完毕后循环播放。

import flash.events.MouseEvent;
import flash.media.Sound;
import flash.net.URLRequest;


//var codes
var AutoPlay:Boolean=true;
var isPlaying:Boolean;
var pausePosition:Number;
var myMusic:Sound;
var soundFile:URLRequest;
var channel:SoundChannel;

// only create music and register event listeners one time
if (myMusic == null)
{
  soundFile = new URLRequest("Fluke.mp3");
 myMusic = new Sound();
  myMusic.load(soundFile);
 pausePosition = 0;
 if (AutoPlay) 
  {
    channel = myMusic.play(pausePosition);
isPlaying = true;
  }
  else
  {
isPlaying = false;
}
pause_btn.addEventListener(MouseEvent.CLICK, pauseSound);
play_btn.addEventListener(MouseEvent.CLICK, playMusic);
channel.addEventListener(Event.SOUND_COMPLETE, onPlaybackComplete);
}

channel.addEventListener(Event.SOUND_COMPLETE, onPlaybackComplete);
function onPlaybackComplete(event:Event) {
pausePosition = 0;
channel = myMusic.play(pausePosition);
isPlaying = true;
channel.addEventListener(Event.SOUND_COMPLETE, onPlaybackComplete);
}


//playbutton functions
function pauseSound(e:MouseEvent):void
{
  if (isPlaying == false) {
    channel = myMusic.play(pausePosition);
    isPlaying =true;
    channel.addEventListener(Event.SOUND_COMPLETE, onPlaybackComplete);
  }else{
    pausePosition=channel.position;
    channel.stop();
    isPlaying=false;
  }
}

//playbutton functions
function playMusic(event:MouseEvent):void
{ 
  if (isPlaying== false) {
    channel=myMusic.play(pausePosition);
    isPlaying=true;
    channel.addEventListener(Event.SOUND_COMPLETE, onPlaybackComplete);
  }
}

Answer 1

我还不能发表评论，所以必须使用答案。

您是否将代码放在单独的 AS 文件中？或者这段代码是否放置在动画的第一帧？

如果是后者，您确实会听到重叠的声音。由于每次播放头返回到第 1 帧时都会执行动作脚本代码；创建一个新的 Sound 对象并开始播放该声音。

一个简单的解决方案是在最后一帧创建关键帧并添加以下动作脚本：

gotoAndPlay(2);

这将从第 2 帧开始循环动画，跳过动作脚本。

另一个可能有效的解决方案（您必须对其进行测试）：

import flash.events.MouseEvent;
import flash.media.Sound;
import flash.net.URLRequest;


//var codes
var AutoPlay:Boolean=true;
var isPlaying:Boolean;
var pausePosition:Number;
var myMusic:Sound;
var soundFile:URLRequest;
var channel:SoundChannel;

// only create music and register event listeners one time
if (myMusic == null)
{
  soundFile = new URLRequest("Fluke.mp3");
  myMusic = new Sound();
  myMusic.load(soundFile);
  pausePosition = 0;
  if (AutoPlay) 
  {
    channel = myMusic.play(pausePosition);
    isPlaying = true;
  }
  else
  {
    isPlaying = false;
  }
  pause_btn.addEventListener(MouseEvent.CLICK, pauseSound);
  play_btn.addEventListener(MouseEvent.CLICK, playMusic);
}

//playbutton functions
function pauseSound(e:MouseEvent):void
{
  if (isPlaying == false) {
    channel = myMusic.play(pausePosition);
    isPlaying =true;
  }else{
    pausePosition=channel.position;
    channel.stop();
    isPlaying=false;
  }
}

//playbutton functions
function playMusic(event:MouseEvent):void
{ 
  if (isPlaying== false) {
    channel=myMusic.play(pausePosition);
    isPlaying=true;
  }
}
