这里的滚动条对应的Actionscript:
on (press) {
    startDrag("", false, start_x, start_y, final_x, start_y);
}
on (release) {
    stopDrag();
    _proportion = (100.0*(this._x-start_x))/(final_x-start_x);
    getURL("lingo:set_volume("+String.fromCharCode(34)+_proportion+String.fromCharCode(34)+"";
}
on (releaseOutside) {
    stopDrag();
}
我将该swf导入到director中，应该如何来控制声音呢，请多指教？因为本人对actionscript不太熟悉。
