我是 Flash 新手，我创建了音量滑块，并且显然为所有音量功能创建了实例，但它给出了以下错误

 TypeError: Error #1010: A term is undefined and has no properties.

以下代码中的确切错误位置是

bgslider.mc.addEventListener(MouseEvent.MOUSE_DOWN,StartDrag);

我的播放器代码是

import flash.events.MouseEvent;
import flash.media.Sound;
import flash.net.URLRequest;
import flash.media.SoundChannel;
import flash.media.SoundTransform;
import flash.events.Event;
import flash.geom.Rectangle;

btnstop.addEventListener(MouseEvent.MOUSE_OUT,StopOut);
btnstopo.addEventListener(MouseEvent.MOUSE_OVER,StopOver);
function StopOver(evt:MouseEvent):void
{
    btnstopo.visible=false;
    btnstop.visible=true;
}

function StopOut(evt:MouseEvent):void
{
    btnstop.visible=false;
    btnstopo.visible=true;
}

btnplay.addEventListener(MouseEvent.MOUSE_OUT,PlayOut);
btnplayo.addEventListener(MouseEvent.MOUSE_OVER,PlayOver);

function PlayOver(evt:MouseEvent):void
{
    btnplayo.visible=false;
    btnplay.visible=true;
}

function PlayOut(evt:MouseEvent):void
{
    btnplay.visible=false;
    btnplayo.visible=true;
}

var soundfile:URLRequest = new URLRequest('http://live32.radio.com:80/;stream1.mp3');
var channel:SoundChannel = new SoundChannel();
var sTransform:SoundTransform = new SoundTransform();

 var isplay=1;
 var myMusic:Sound = new Sound();  
 myMusic.load(soundfile);
 channel=myMusic.play(); 

btnplay.addEventListener(MouseEvent.CLICK,PlayRadio);
btnstop.addEventListener(MouseEvent.CLICK,StopRadio);

function PlayRadio(evt:Event):void
{
    if(isplay==0)
    {
        isplay=1;       
        btnplay.removeEventListener(MouseEvent.MOUSE_OUT,PlayOut);
        btnplayo.removeEventListener(MouseEvent.MOUSE_OVER,PlayOver);
        btnstop.addEventListener(MouseEvent.MOUSE_OUT,StopOut);
        btnstopo.addEventListener(MouseEvent.MOUSE_OVER,StopOver);
        SoundMixer.soundTransform = new SoundTransform(1);
        btnstop.visible=true;
        btnplay.visible=false;
    }
}

function StopRadio(evt:Event):void
{
    if(isplay==1)
    {
        btnstop.removeEventListener(MouseEvent.MOUSE_OUT,StopOut);
        btnstopo.removeEventListener(MouseEvent.MOUSE_OVER,StopOver);
        btnplay.addEventListener(MouseEvent.MOUSE_OUT,PlayOut);
        btnplayo.addEventListener(MouseEvent.MOUSE_OVER,PlayOver);
        SoundMixer.soundTransform = new SoundTransform(0);
        isplay=0;
        btnstop.visible=false;
        btnplay.visible=true;
    }
}

/*var bgslider = new MovieClip();
trace(bgslider.name);

for(var i:uint=0;i<bgslider.numChildren;i++){
trace(bgslider.getChildAt(i).name);
}*/
bgslider.mc.addEventListener(MouseEvent.MOUSE_DOWN,StartDrag);
bgslider.mc.addEventListener(MouseEvent.MOUSE_UP,StopDrag);
function StartDrag(event:MouseEvent):void
{
    bgslider.mc.startDrag(true,new Rectangle(152,37,182,0));
}
function StopDrag(event:MouseEvent):void
{
    bgslider.mc.stopDrag();
}

请任何人给出正确答案，谢谢提前

该 TypeError 通常表明您拼错了一个对象引用或根本没有给它一个。

在属性检查器中仔细检查您的 bgslider 和 mc 参考。确保它没有被称为 bg_slider、bgSlider 或类似名称。
