示例

以下示例附加到滑动条的尖端。当加载此剪辑时，Flash 将检查值 myMic.gain，如果该值未定义，则提供默认值。然后，使用 _x 位置将麦克风的增益设置为用户的首选项。

onClipEvent (load) {
  if (_root.myMic.gain == undefined) {
    _root.myMic.setGain = 75;
  }

  this._x = _root.myMic.gain;
  _root.txt_micgain = this._x;

  left = this._x;
  right = left+50;
  top = this._y;
  bottom = top;
}

on (press) {
  startDrag(this, false, left, top, right, bottom);
  this._xscale = 100;
  this._yscale = 100;
}

on (release, releaseOutside) {
  stopDrag();
  g = (this._x-50)*2;
  _root.myMic.setGain(g);
  _root.txt_micgain = g;
  this._xscale = 100;
  this._yscale = 100;
}
