Question

如何通过按钮在Flash / AS3中播放/停止嵌入音乐文件？

这就是我所拥有的：

import flash.events.Event;  
import flash.events.MouseEvent;
import flash.display.MovieClip;  
import flash.media.Sound;
import flash.media.SoundChannel;

var myMusic:Sound = new ThemeSong(); 
var channel:SoundChannel = myMusic.play();

startButton.addEventListener(MouseEvent.CLICK, onStartClick);
stopButton.addEventListener(MouseEvent.CLICK, onStopClick);

function onStartClick(event:MouseEvent):void{
    myMusic.play();
}

function onStopClick(event:MouseEvent):void{
    myMusic.stop();
}

ThemeSong是我为音乐文件指定的类的名称（import - ＆gt; libraries - ＆gt; properties - ＆gt; export for AS - ＆gt; class name）。 startButton和stopButton是按钮的标识符。

如果我执行此操作，我会收到错误消息：

"Scene 1, Layer 'actions', Frame 1, Line 69 1061: Call to a possibly undefined method stop through a reference with static type flash.media:Sound."

感谢。

你很接近Flash有时候会很糟糕：

import flash.events.Event;  
import flash.events.MouseEvent;
import flash.display.MovieClip;  
import flash.media.Sound;
import flash.media.SoundChannel;

var myMusic:Sound = new ThemeSong(); 
var channel:SoundChannel = myMusic.play();

startButton.addEventListener(MouseEvent.CLICK, onStartClick);
stopButton.addEventListener(MouseEvent.CLICK, onStopClick);

function onStartClick(event:MouseEvent):void{
    channel = myMusic.play();
}

function onStopClick(event:MouseEvent):void{
    channel.stop();
}
