因为全是as编写的，所以我就不放源文件了，只要把as代码复制到flash里的第一帧就可以了

Stage.scaleMode = "noScale"
Stage.align = "TL"
for (i=1; i<=4; i++) {
_root.createEmptyMovieClip("point"+i, 0-i);//新建MC
//mc的x轴，y轴
_root["point"+i]._x = Stage.width/2;
_root["point"+i]._y = Stage.height/2;
//鼠标划过的效果
_root["point"+i].onMouseMove = function() {
this._x = _root._xmouse+(Math.random()*70)-35;
this._y = _root._ymouse+(Math.random()*70)-35;
};
}
//设定一个颜色组
hexColors = new Array("0xCC00FF", "0xCC33FF", "0xCC66FF", "0xCC99FF", "0xCCCCFF", "0xCCFFFF");
//鼠标划过时新建mc，并随机填充颜色和随机设alpha值
this.onMouseMove = function() {
i++;
this.createEmptyMovieClip("shape"+i, i *10);
with (this["shape"+i]) {
beginFill(hexColors[Math.floor(Math.random()*hexColors.length)], (Math.random()*40)+60);
//执行画线程序
moveTo(_root.point1._x, _root.point1._y);
curveTo(_root.point2._x, _root.point2._y, _root.point3._x, _root.point3._y);
curveTo(_root.point4._x, _root.point4._y, _root.point1._x, _root.point1._y);
endFill();
}
//复制当前mc，设X，Y轴，alpha值，并填充颜色，做为阴影。
this["shape"+i].duplicateMovieClip("shadow"+i, (10*i)-1);
this["shadow"+i]._x = this["shape"+i]._x -6;
this["shadow"+i]._y = this["shape"+i]._y + 6;
this["shadow"+i]._alpha = 60;
this.grey = new Color(this["shadow"+i]);
this.grey.setRGB("0x999999");
};

只做了简单的解释，适合有as基础的朋友学习

this._y = _root._ymouse+(Math.random()*70)-35;
};
}
//设定一个颜色组

endFill();
}
//复制当前mc，设X，Y轴，alpha值，并填充颜色，做为阴影。

this.grey = new Color(this["shadow"+i]);
this.grey.setRGB("0x999999");
};
//加了一段删除的
var ii:Number = 6;
function del() {

_root["shape"+ii].removeMovieClip();
_root["shadow"+ii].removeMovieClip();

}
}
setInterval(del, 10);
