拖动,缓动,加投影效果

作者：袖梨 2022-07-02

在此谢谢我师兄,昨晚的相助,呵呵~~ (webstudio 里的一个特效制作), 有兴趣的,可以一起把它做得更好~哈哈... 占用一下地方上传文件,也分享一下,呵呵~ 转载请注明~

import flash.filters.DropShadowFilter;
var filterropShadowFilter = new DropShadowFilter(10, 45, 0x666666, .6, 18, 18, 1, 3, false, false, false);
var filterArray:Array = new Array();
filterArray.push(filter);
var loop:Number;
var grav:Number;
function move() {
this._x += grav*(_root._xmouse-this._x)/loop;
this._y += grav*(_root._ymouse-this._y)/loop;
if (this._x+15 == _root._xmouse+15 || this._y+15 == _root._ymouse+15) {
  //drag = false
  group_mc.filters = null;
} else {
  this.filters = filterArray;
}
//trace(grav)
//trace(loop)
}
var drag:Boolean = false;
group_mc.onPress = function() {
drag = true;
grav = .6;
loop = 1;
};
group_mc.onMouseMove = function() {
if (drag) {
  grav = .1;
  //loop = 10;
  move.call(this);
}
};
group_mc.onRelease = group_mc.onReleaseOutside=function () {
drag = false;
//delete onEnterFrame;
};
group_mc.onEnterFrame = function() {
if (drag) {
  move.call(this);
} else {
  group_mc.filters = null;
}
};

半夜又完善了一下效果,再加一个动态投影下去,效果就完全出来了~ 可以参考这里的教程: /tutorial/show.php?id=65

filter.blurY=filter.blurX = Math.abs((this._x-_root._xmouse)/3);

filter.distance=(this._x-_root._xmouse)/5;

this.filters = filterArray;

用3.0写了一遍,3.0里没有 events as onReleaseOutside, onDragOut, onDragOver and so on.所以得自己写events类,呵呵~~下次研究一下,再一起讨论共享.
