代码如下所述:

  object.environment = this;
  math.prototype.degrees = function (r)
  {
  return (r * 180 / 3.141593e+000);
  };
  maxtents = 3;
  this.onenterframe = function ()
  {
  if (!random(30) && tents < maxtents)
  {
  var nombre = “tent” + string(depth++);
  var neo = this.attachmovie(“tentacle”, nombre, depth);
  neo._x = random(600);
  neo._y = 370;
  neo.theta = 270;
  ++tents;
  } // end if
  };
  stop ()

#initclip 1
