flash - 播放音频时使闪光灯按钮消失

Question

我有一个Flash文档(Actionscript-3)，该图像的顶部有播放按钮，单击该按钮时会播放音频。单击播放音频时如何使播放按钮消失。音频播放完毕后，该按钮应重新出现。

Answer 1

在您的按钮中单击处理程序:

protected function click_Button(e:MouseEvent):void {
    (e.currentTarget as DisplayObject).visible=false;
    var sound:SoundChannel = yourSound.play(0, 1);
    sound.addEventListener(Event.SOUND_COMPLETE, onSoundComplete);
}

protected function onSoundComplete(e:Event):void {
    yourButton.visible = true;
    (e.currentTarget as EventDispatcher).removeEventListener(Event.SOUND_COMPLETE, onSoundComplete);
}
