Question

我试图在用户点击按钮时停止播放歌曲，这是我的代码：

var mySound:MainSound = new MainSound();
var cmyChannel :SoundChannel;

animation_play.addEventListener(MouseEvent.CLICK, playSound);

function playSound(event:Event) {
mySound.play();
}

animation_stop.addEventListener(MouseEvent.CLICK, stopSound);
function stopSound(event:Event) {
mySound.stop();
}


animation_play.addEventListener(MouseEvent.CLICK,    fl_ClickToGoToAndPlayFromFrame_3);

function fl_ClickToGoToAndPlayFromFrame_3(event:MouseEvent):void
{
   gotoAndPlay(2);
}

当我点击animation_play对象时，它完全正常，它通过播放声音并从指定帧开始动画来实现。但是如果我点击animation_stop对象我会收到错误

TypeError: Error #1006: stop is not a function.

任何人都知道如何解决这个问题？

Answer 1

要停止声音，您必须使用这样的SoundChannel对象，例如：

function playSound(event:Event): void 
{
    cmyChannel = mySound.play();
}

和

function stopSound(event:Event): void  
{
    cmyChannel.stop();
}

希望可以提供帮助。

Answer 2

您需要将mySound.play()设置为cmyChannel对象。然后在stop上致电cmyChannel。这是代码：

var mySound:MainSound = new MainSound();
var cmyChannel :SoundChannel;

animation_play.addEventListener(MouseEvent.CLICK, playSound);

function playSound(event:Event) {
cmyChannel  = mySound.play();
}

animation_stop.addEventListener(MouseEvent.CLICK, stopSound);
function stopSound(event:Event) {
cmyChannel.stop();
}


animation_play.addEventListener(MouseEvent.CLICK,    fl_ClickToGoToAndPlayFromFrame_3);

function fl_ClickToGoToAndPlayFromFrame_3(event:MouseEvent):void
{
   gotoAndPlay(2);
}
