刚做完项目，空闲时间比较多，无聊利用上班时间写了个俄罗斯方块，欢迎大家试玩。
试玩过程中有bug或者好的建议，请在这里留言，谢谢！

2009年8月11日修改：
根据各位兄弟的建议，修改如下：
1.似乎只有L，做漏了反L
该bug已修正
2.对于2（2还是反2忘了），其中一个的变形好像有点不对。相对于传统的变形。似乎变后左移了一格。感觉怪怪的。。
已修正
3.还真有BUG
开始游戏，调到最高级后，绿色Z形的方块落下后，再往上面加别的方块中间有一行空的。不能落下。。
这个似乎已修正^_^
4.GAME OVER后，选级别，还会有方块出来。。并下落
已修正
5.呵呵，有bug，当你挂了过后，现start 级别的下拉框里会再添加1到10级，呵呵
已修正
6.这么多代码咋连个注释都没有~，能否把思路简单的说一说
太晚了，改天再做，不好意思
7.增加了三个块，分别是加长T，加长Z和凹形块，难度加大，各位有兴趣可以再玩玩
2009年8月12日修改：
昨晚花了一个多小时优化了一下，从8月11日的765行代码减少到680行。主要变动如下：
1.清除了一些用不到的局部变量，全局变量，数组比如SmallMap: []，IsMoving，TotalScore等
2.合并GetInactivateBlocks和GetActiviteBlocks为GetBlocks，通过参数isActive来判断
3.合并_getBlocksItemPosArray和_getRelativeBlocksItemPosArray为_getBlocksItemPosArray，通过参数isRelative判断
4.抽取下面的代码为一个独立函数GetBlocksFromSmallMap，因为GetNextActiviteBrocks和PlayGame都用到了
this.BlocksObj[0].isInGameMap = true;
var itemPos = this.GetBlocksInitPos();
this.BlocksObj[0].x = itemPos.x;
this.BlocksObj[0].y = itemPos.y;
this.BlocksObj[0].AddToGameMap(this.BlocksObj[0].color, this.BlocksObj[0].isInGameMap);
5.AllowChangeShape函数清除，其内部逻辑并到ChangeShape函数里面
6.合并moving和else if (e.keyCode == 40)下的代码成为一个独立函数BlocksMoveDown
7.合并AddToSmallMap和AddToGameMap为AddToMap，去掉原来的参数，修改为isAddToSmallMap,isMoving
8.以下代码抽取出来成为 一个独立函数GetMaxAndMinItemPosArray，返回json字符串，因两处函数用到了
itemPosArray.ItemPosXArray.sorts();
itemPosArray.ItemPosYArray.sorts();
var maxItemPosX = itemPosArray.ItemPosXArray[itemPosArray.ItemPosXArray.length - 1];
var minItemPosX = itemPosArray.ItemPosXArray[0];
var maxItemPosY = itemPosArray.ItemPosYArray[itemPosArray.ItemPosYArray.length - 1];
var minItemPosY = itemPosArray.ItemPosYArray[0];
2009-08-16修改：
代码由最初的760精简到600行左右（去掉注释后的统计）
1.取消CreateBlocksShapeMaps和_createBlocksShapeMap函数，提前定义BlocksShapeMaps数组
2.重构AllowBlocksMove，统一向上，向下，向右时方块集移动的行为，取消
_allowBlocksDown函数，增加NoToBoundary函数，判断边界
3.增加代码注释和设计理念
以下是08-16最新更新的代码：

//游戏设计说明：
//1.由于该游戏属于二维游戏，所以布置好网格是写好该游戏的关键，无论是游戏窗口还是预览窗口、
//方块集虚拟map等都用到了网格的概念，这样做的好处可以避免频繁的获取元素的位置，另外还可以对方块集的移动
//进行精确的定位和变形。这里比较重要的一点就是提前定义好方块集的map，比如对于L方块集，应定义一个三乘三的正方形
//网格,然后根据L的每一个形状，确定方块集中的每个方块在正方形网格中的位置，另外还需要保存方块集在map
//（游戏窗口或者预览窗）中的位置，这样任意时刻，通过方块集的位置，和方块在正方形网格中的位置，就可以确定
//方块集中的每一个方块在map中的位置。
//2.该游戏主要用到了一些OOP的思想。比如定义一个基类base，方块集类继承自base类,其中还有对象的封装，属性，
//枚举的定义等,当然还有事件，委托，attribute，垃圾收集器等，因为时间关系，就不做代码演示了，各位有兴趣可以自己
//扩展一下，加深对js OOP的理解。
//3.js内置对象的扩展：比如Array.prototype.removeAt等
