如何添加2音量滑塊到我的MP3播放器as3

Question

容易的人。我目前正試圖添加2個音量滑塊到我現有的項目。我有兩個唱盤，deck1 & deck2，但我需要能夠單獨控制每個唱片的音量。

即時通訊相對較新的動作3所以即時通訊掙扎abit。誰能幫我請，這裏是我的代碼..

import flash.events.MouseEvent; 
import flash.display.Sprite; 
import flash.display.Graphics; 
import flash.events.Event; 
import flash.media.Sound; 
import flash.media.SoundChannel; 
import flash.media.SoundMixer; 
import flash.net.URLRequest; 
import flash.utils.ByteArray; 
import flash.text.TextField; 

//variables 
var mySound:Sound; 
var myChannel:SoundChannel; 
var nowPlaying:Boolean = false; 
var nowPaused:Boolean = false; 
var p:uint = 0; 
var songfile:String; 
var songtitle:String; 

deck1_btn.addEventListener(MouseEvent.CLICK, deck1_data); 
deck2_btn.addEventListener(MouseEvent.CLICK, deck2_data); 
//song3_btn.addEventListener(MouseEvent.CLICK, song3_data); 
stop_btn.addEventListener(MouseEvent.CLICK, stopSound); 
stop2_btn.addEventListener(MouseEvent.CLICK, stopSound); 

pause_btn.addEventListener(MouseEvent.CLICK, pauseSound); 

function deck1_data(myEvent:MouseEvent):void { 
songfile = "audio/desire.mp3"; 
songtitle = "Skeptical - Desire"; 
playSound(null); 
    } 
    function deck2_data(myEvent:MouseEvent):void { 
songfile = "audio/tundra.mp3"; 
songtitle = "Skeptical - Tundra"; 
playSound(null); 
    } 
    //function song3_data(myEvent:MouseEvent):void { 
songfile = "audio/always_be_mine.mp3"; 
songtitle = "Skeptical - Always Be Mine"; 
playSound(null); 

    function stopSound(myEvent:MouseEvent):void { 
if (nowPlaying) { 
myChannel.stop(); 
p = 0; 
nowPlaying = false; 
nowPaused = false; 
    } 
    } 


    function playSound(myEvent:Event):void { 
    mySound = new Sound; 
    mySound.load(new URLRequest(songfile)); 
    title_txt.text = songtitle; 
if (isPlaying) { 
    myChannel.stop(); 
    myChannel = mySound.play(0); 
} else { 
    myChannel = mySound.play(0); 
    nowPlaying = true; 
    } 
    } 

    function pauseSound(myEvent:MouseEvent):void { 
if (isPlaying) { 
    p = Math.floor(myChannel.position); 
    myChannel.stop(); 
    nowPlaying = false; 
    nowPaused = true; 
} else if (nowPaused) { 
    myChannel = mySound.play(p); 
    nowPlaying = true; 
    nowPaused = false; 
} 
    } 

    title_txt.text = ""; 

Answer 1

爲了控制音量，您將需要SoundTransform。創建滑塊，並將卷存儲爲數字。當你開始甲板聲音，應用soundTransform與甲板體積值：

myChannel = mySound.play(0, 0, new SoundTransform(myDeck1Volume)); 
//or 
//myChannel = mySound.play(0, 0, new SoundTransform(myDeck2Volume)); 

至於滑塊。你可以使用Slider component
