重叠的声音的ActionScript 3/AIR

Question

我有一个播放（恢复）/第1帧中暂停按钮（主页）。但是，当用户导航应用程序并通过按主页按钮决定返回主页时，声音重叠。而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在Android设备上部署的Actionscript 3 Flash应用程序。这是我的代码：

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

这就是你通过在帧而不是类编码。解决方案A：从您的第1帧脚本中创建一个类，以便仅执行一次（创建主时间线时）。

解决方案B：创建重复之前进行检查：

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); 
}
