音量控制：
onClipEvent (load) {
    top = _y;
    left = _x;
    right = _x;
    bottom = _y+100;
}
onClipEvent (enterFrame) {
    if (dragging == ture) {
        _root.s.setVolume(100-(_y-top));
    }
}



声道控制：
onClipEvent (load) {
    top = _y;
    bottom = _y;
    left = _x-50;
    right = _x+50;
    center = _x;
}
onClipEvent (enterFrame) {
    if (dragging == true) {
        _root.s.setPan((_x-center)*2);
    }
}
这个脚本有无错误，我用mx检测无错误，可是在swf中无作用！
这个是在flash5中写的！
