 function playrandomsong(e:Event)

 }

这是一个Actionscript 3代码，用于从本地目录中随机播放数组中的MP3。它的工作原理，但我的问题是我使用它的应用程序较旧，不支持AS3 - 只有AS2及更早版本。有谁知道这段代码的等价物是什么？

Answer 1

在AS2中，没有导入的包存在，没有，Event，SoundChannel或URLRequest类，Sound类接口不同。

未测试：

var sound:Sound;
var randnum:Number;

function playsong()
{
    randnum = Math.floor(Math.random() * 127);
    var songs:String = "part" + randnum + ".mp3";  

    sound = new Sound();
    sound.onSoundComplete = playrandomsong;
    sound.loadSound("file:///D:/parts/" + songs, true);
}

function playrandomsong()
{
    playsong();
}

在Actionscript 2中随机化MP3文件
