Question

我以为我可以更改布尔值true / false值，但它不起作用。在按下按钮之前，如何让它静音？

import flash.media.Sound;
import flash.media.SoundChannel;

var soundOn:Boolean = true; //music is ON when we start
var myToons:TitleMusic = new TitleMusic();
var myChannel:SoundChannel = myToons.play(0,1000); // endless loop, in effect
var myTransform:SoundTransform;

mySoundButton.addEventListener(MouseEvent.CLICK,toggleSound);
mySoundButton.buttonMode = true;
mySoundButton.mouseChildren = false;


function toggleSound(e:MouseEvent)
{
    if(soundOn)
    {
        // turn sound off
        myTransform = new SoundTransform();
        myTransform.volume = 0; // silent
        myChannel.soundTransform = myTransform;
        soundOn = false;
        mySoundButton.myButtonText.text = "click to turn sound ON";
    }
    else // sound is off
    {
        // turn sound on
        myTransform = new SoundTransform();
        myTransform.volume = 1; // full volume
        myChannel.soundTransform = myTransform;
        soundOn = true;
        mySoundButton.myButtonText.text = "click to turn sound OFF";
    }

}

不需要布尔语句。这就是我所做的。

变量'mySound'实例化声音。我将声音控制权交给'myChannel'。组件面板中的按钮有名称。确保正确设置mp3属性，命名为'Sound，Class'Sound'。一切都应该有效！

播放并停止嵌入式mp3

                /*      
                place mp3 in library. 
                Give it a Name and Class of 'Sound'
                */
        var mySound:Sound = new Sound();
                //control the channel that your sound is on
        var myChannel:SoundChannel = new SoundChannel();
playButton.addEventListener (MouseEvent.CLICK, myPlayButtonHandler);
                /*
                Grab a Play and Stop button from the components menu.
                Go to Properties Panel and give each an instance name.
                Play is 'playButton', Stop is 'stopButton'
                */
        function myPlayButtonHandler (e:MouseEvent):void {
                //mySound.play();//use channel instead 
            myChannel = mySound.play();
            }
                //Stopping the sound channel
stopButton.addEventListener(MouseEvent.CLICK, onClickStop);
        function onClickStop(e:MouseEvent):void{
            myChannel.stop();
            }

加载外部mp3选项

            //URL load and auto play of external file "myMp3.mp3"
            var mySound:Sound = new Sound();
            snd.load(new URLRequest("myMp3.mp3"));
            snd.play();

电影静音，直到按下按钮，闪烁as3
