Question

求解：关于flash as2.0代码的问题？

for(i=1;i<37;i++){
this.attachMovie("pic"+i,"pic"+i+"_mc",this.getNextHighestDepth()); var pic_mc = eval("pic"+i+"_mc"); pic_mc._x = 150 +random(200); pic_mc._y = 100 + random(200); } pic1_mc.onRelease = function(){ var zddepth =_root.getNextHighestDepth()-1; var zd_mc:MovieClip =_root.getInstanceAtDepth(zddepth); this.swapDepths(zd_mc); } pic2_mc.onRelease = function(){ var zddepth = _root.getNextHighestDepth()-1; var zd_mc:MovieClip = _root.getInstanceAtDepth(zddepth); this.swapDepths(zd_mc); } pic3_mc.onRelease = function(){ var zddepth = _root.getNextHighestDepth()-1; var zd_mc:MovieClip = _root.getInstanceAtDepth(zddepth); this.swapDepths(zd_mc); } pic4_mc.onRelease = function(){ var zddepth = _root.getNextHighestDepth()-1; var zd_mc:MovieClip = _root.getInstanceAtDepth(zddepth); this.swapDepths(zd_mc); } pic5_mc.onRelease = function(){ var zddepth = _root.getNextHighestDepth()-1; var zd_mc:MovieClip = _root.getInstanceAtDepth(zddepth); this.swapDepths(zd_mc); }
请帮忙解释一下上述代码的意思

//从库里面调出35图片（这里是影片剪辑），
for (i = 1; i < 37; i++)
{
	this.attachMovie("pic" + i,"pic" + i + "_mc",this.getNextHighestDepth());
	//对这些mc民命
	var pic_mc = eval("pic" + i + "_mc");
	//随机他们的坐标
	pic_mc._x = 150 + random(200);
	pic_mc._y = 100 + random(200);
}
//以下是对这些按钮添加点击事件，
pic1_mc.onRelease = function()
{
	//把当前点击的这个图片（影片剪辑）放到舞台最上层。
	var zddepth = _root.getNextHighestDepth() - 1;
	var zd_mc:MovieClip = _root.getInstanceAtDepth(zddepth);
	this.swapDepths(zd_mc);
};
pic2_mc.onRelease = function()
{
	var zddepth = _root.getNextHighestDepth() - 1;
	var zd_mc:MovieClip = _root.getInstanceAtDepth(zddepth);
	this.swapDepths(zd_mc);
};
pic3_mc.onRelease = function()
{
	var zddepth = _root.getNextHighestDepth() - 1;
	var zd_mc:MovieClip = _root.getInstanceAtDepth(zddepth);
	this.swapDepths(zd_mc);
};
pic4_mc.onRelease = function()
{
	var zddepth = _root.getNextHighestDepth() - 1;
	var zd_mc:MovieClip = _root.getInstanceAtDepth(zddepth);
	this.swapDepths(zd_mc);
};
pic5_mc.onRelease = function()
{
	var zddepth = _root.getNextHighestDepth() - 1;
	var zd_mc:MovieClip = _root.getInstanceAtDepth(zddepth);
	this.swapDepths(zd_mc);
};


//上面的写法很不科学
//你可以使用下面的写法

for (i = 1; i < 37; i++)
{
	this.attachMovie("pic" + i,"pic" + i + "_mc",this.getNextHighestDepth());
	//对这些mc民命
	var pic_mc = eval("pic" + i + "_mc");
	//随机他们的坐标
	pic_mc._x = 150 + random(200);
	pic_mc._y = 100 + random(200);
	pic_mc.onRelease = function()
	{
		var zddepth = _root.getNextHighestDepth() - 1;
		var pic_mc:MovieClip = _root.getInstanceAtDepth(zddepth);
		this.swapDepths(pic_mc);
	};
}
