1.前言
写这个jQuery版本的小游戏的缘由在于我想通过从零到有，自己写一个Jquery版本的游戏用来练手，没参考过其他人代码，这样子才不会影响自己的思路。
经历了V1，V2版本，当前版本是V3，版本说明如下：
V1: Use two methods of left and right conflict check, bottom conflict check.
V2: Use U style conflict check for left and right and bottom.
V2.1: add keyDownRaip when press v_down key.
V2.0.2:add Debug Zone for test and theft operation based V2.
V3:UI adjust for lj.w based V2.0.2
V3.1:Add function of Pageviews and Leaderboard.
V4.0:Add function of auto adjust UI

2.游戏说明
功能：关卡，分数，暂停，虚拟键，状态栏，自定义宽高大小，还有金手指。
在线试玩地址：play online
游戏界面如下：
3.难点及开发时遇到的问题汇总
1.碰撞检测和模型设计
答：在V1版本由于设计模型不合理导致碰撞检测不完美，而且得付出更多代价，后面改成了U模型。
2.当cube下降到底部，该给予短时间移动方块（符合游戏玩法）
答：给setTimeout，并延迟刷新二维数据
3.方块旋转
答：详情请见KeyHanderUp方法
4.触发下一个cube
答：之前用定时器刷新，后来改为当碰到下边界，触发Next();
5.下降碰到边界向左或向右移动，此时该cube下面为可降落
答：详情请见KeyHanderDown方法6. to be continued ...
4.源码分析
方法说明：
InitUI(): 初始化界面，绘制出UI
InitData():初始化所有参数
InitVK():初始化并绑定button的响应事件
InitData():初始化所有参数
InitVK():初始化并绑定button的响应事件
InitAllCubeStatusArr:初始化二维矩阵
printAllCubeStatusArr:打印二维矩阵，在console打印
UpdateAllCubeStatusArr:更新二维矩阵
RefreshDrawUI:重绘左侧主区UI
CheckRemoveRowInline:判定是否为可以删除行
RemoveRowInline:删除指定行
UpdateScore:更新分数
UpdateLevel:更新关卡
CheckGameOver:判定是否Game Over
TextSatutsTimeOut:右下角状态栏显示秒数和内容
Int:取整操作
CheckNextStatusIsBoundary:判定是否到达边界
CubeInBlock:碰撞检测的核心代码
Types:俄罗斯方块的7中类型
KeyHanderUp/KeyHanderDown/KeyHanderLeft/KeyHanderRight:上下左右操作
UpdatePosNextStatus:更新下一个位置的状态位，为边界判定服务。
showCurTypeInMainBoard:显示当前的方块
GetRandType:获取随机数，从而获得下一个候选区的方块
ShowCandidateType:显示候选区方块
DrawMainUI:绘制左侧主区UI
DrawCandidateZoneUI:绘制候选区主区UI
DrawOperationZoneUI:绘制操作区UI
Start:获取候选区方块
Next:下一个方块降落
Play:点击play按钮触发，点击后变成pause，可以暂停游戏

6.总结
我敲代码，可以认认真真地敲到凌晨1点，这个是我之前没预期到的。
开发时，要用版本工具来控制，我使用TortoiseSVN。
