重叠声音Actionscript 3/AIR

Question

我在第1帧(主页)中有一个播放(恢复)/Pause按钮。但是，当用户导航应用程序并决定通过按下Home按钮返回到home Page时，声音会重叠。当用户按下其他按钮时，它开始无休止地重叠。谢谢!这是一个使用Adobe AIR部署在Android设备上的Actionscript 3 Flash应用程序。下面是我的代码：

import flash.net.URLRequest;
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.ui.Mouse;
import flash.events.MouseEvent;

var played:Boolean = false;
var soundFile:URLRequest = new URLRequest("music.mp3");
var mySound:Sound = new Sound;

if(played== false){
            played= true;
mySound.load(soundFile);
var myChannel:SoundChannel = new SoundChannel;
myChannel = mySound.play(0,999);

pause_btn.addEventListener(MouseEvent.CLICK,pauseSound)
function pauseSound(event:MouseEvent):void 
    {
        var position = myChannel.position;
        myChannel.stop();
        play_btn.addEventListener(MouseEvent.CLICK,resumeSound);
        }

function resumeSound(event:MouseEvent):void
    {
        myChannel = mySound.play(myChannel.position);
    }
}

Answer 1

这是通过在帧而不是类中编码而得到的。

解决方案A:在第1帧脚本中创建一个类，以便只执行一次(创建主时间线时)。

解决方案B:创建副本前进行检查：

var played:Boolean;

var mySound:Sound;
var myChannel:SoundChannel

// That will be executed only once, because the
// next time this variable will be initialized.
if (mySound == null)
{
    played = true;

    var soundFile:URLRequest = new URLRequest("music.mp3");

    mySound = new Sound;
    mySound.load(soundFile);
    myChannel = new SoundChannel;
    myChannel = mySound.play(0,999);

    pause_btn.addEventListener(MouseEvent.CLICK,pauseSound);
}
