Flash制作美丽的蜻蜓飞舞效果动画

　7.新建立一个图层＂蜻蜓＂，然后把蜻蜓电影剪辑从酷中拖出来，依次重复5次，打开属性面板，分别给蜻蜓命名实例名为fly1，fly2，fly3，fly4，fly5，效果如下：

　　8.新建立一个图层＂trans＂，然后把蜻蜓电影剪辑从酷中拖出来，依次重复5次，打开属性面板，分别给蜻蜓命名实例名为transp1，transp2，transp3，transp4，transp5，效果如下：

　　9.新建立一个图层＂action＂，按F9打开动作面板添加如下指令代码：

probability = 30;
scene_width = 550;
scene_height = 300;
speed = 0.03;
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.transp1.onEnterFrame = function () {
if (random (probability) == 0) {
target1X = random (scene_width);
target1Y = random (scene_height);
}
this._visible = 0;
this.smoothMove (speed, target1X, target1Y);
};
_root.fly1.onEnterFrame = function () {
this.smoothMove (speed, transp1._x, _root.transp1._y);
this.rotateTo (_root.transp1._x, _root.transp1._y);
};
_root.transp2.onEnterFrame = function () {
if (random (probability) == 0) {
target2X = random (scene_width);
target2Y = random (scene_height);
}
this._visible = 0;
this.smoothMove (speed, target2X, target2Y);
};
_root.fly2.onEnterFrame = function () {
this.smoothMove (speed, transp2._x, _root.transp2._y);
this.rotateTo (_root.transp2._x, _root.transp2._y);
};
_root.transp3.onEnterFrame = function () {
if (random (probability) == 0) {
target3X = random (scene_width);
target3Y = random (scene_height);
}
this._visible = 0;
this.smoothMove (speed, target3X, target3Y);
};
_root.fly3.onEnterFrame = function () {
this.smoothMove (speed, transp3._x, _root.transp3._y);
this.rotateTo (_root.transp3._x, _root.transp3._y);
};
_root.transp4.onEnterFrame = function () {
if (random (probability) == 0) {
target4X = random (scene_width);
target4Y = random (scene_height);
}
this._visible = 0;
this.smoothMove (speed, target4X, target4Y);
};
_root.fly4.onEnterFrame = function () {
this.smoothMove (speed, transp4._x, _root.transp4._y);
this.rotateTo (_root.transp4._x, _root.transp4._y);
};
_root.transp5.onEnterFrame = function () {
if (random (probability) == 0) {
target5X = random (scene_width);
target5Y = random (scene_height);
}
this._visible = 0;
this.smoothMove (speed, target5X, target5Y);
};
_root.fly5.onEnterFrame = function () {
this.smoothMove (speed, transp5._x, _root.transp5._y);
this.rotateTo (_root.transp5._x, _root.transp5._y);
};

　　10.时间轴最终效果如下图所示：
