  8.新建一个图层,然后把“引用”、“引用2”和辅助拖出来,注意辅助要拖两次,放置效果如下图:


  然后分别给“引用”命名实例名为fly0_mc,“引用2”实例名为fly1_mc,辅助的实例名为:transp0、transp1。

  9.新建一个图层改名为action,然后按F9打开动作面板,输入如下动作:

probability = 100;
scene_width = 500;
scene_height = 290;
speed = 0.03;
depth = 15;
MovieClip.prototype.smoothMove = function (speed, targetx, targety) {
 this._x += speed*(targetx-this._x);
 this._y += speed*(targety-this._y);
};
MovieClip.prototype.rotateTo = function (targetx, targety) {
 var diffX = targetx-this._x;
 var diffY = targety-this._y;
 this._rotation = Math.atan2 (diffY, diffX)*180/Math.PI;
};
_root.transp0.onEnterFrame = function () {
 if (random (probability) == 1) {
  target0X = random (scene_width);
  target0Y = random (scene_height);
 }
 this._visible = 0;
 this.smoothMove (speed, target0X, target0Y);
};
_root.transp1.onEnterFrame = function () {
 if (random (probability) == 1) {
  target1X = random (scene_width);
  target1Y = random (scene_height);
 }
 this._visible = 0;
 this.smoothMove (speed, target1X, target1Y);
};
_root.fly0_mc.onEnterFrame = function () {
 this.smoothMove (speed, transp0._x, _root.transp0._y);
 this.rotateTo (_root.transp0._x, _root.transp0._y);
};
_root.fly1_mc.onEnterFrame = function () {
 this.smoothMove (speed, transp1._x, _root.transp1._y);
 this.rotateTo (_root.transp1._x, _root.transp1._y);
};
_root.shadow0_mc.onEnterFrame = function () {
 this.smoothMove (speed, transp0._x, _root.transp0._y+depth);
 this.rotateTo (_root.transp0._x, _root.transp0._y+depth);
};
_root.shadow1_mc.onEnterFrame = function () {
 this.smoothMove (speed, transp1._x, _root.transp1._y+depth);
 this.rotateTo (_root.transp1._x, _root.transp1._y+depth);
};

  动画制作完成,按Ctrl+回车键可以测试动画了!Thank you!
