我的俄罗斯方块项目总结1
获奖学员：陈启壮
所获奖项：三等奖
内容
俄罗斯方块一共三个类中间用等号隔开
软件的开发过程
1 明确业务需求
用自然语言，将业务功能描述清楚
...
2 业务分析
找到有哪些业务对象,和图片的分析
tetris(俄罗斯方块)
｜－－ score 累计分数
｜－－ lines 销毁的行数
｜－－ Wall（墙 20行x10列）
｜－－ 20row(行)
｜－－10 col cell(列)
｜－－ tetromino（4格方块，有7种形态）
｜－－ 4 cell
｜－－nextOne 下一个准备下落的方块
｜－－ 4 cell
3 数据模型,一切业务对象转换为数字表示
场地按照行列划分为20x10格子
格子有属性row,col,color
4 类 设计
Tetris
|-- int score
|-- int lines
|-- Cell[20][10] wall
|-- Tetromino tetromino
| |--Cell[4] cells
|-- row
|-- col
|-- color
5 算法设计，就是如何利用数据的计算实现软件的功能
4格方块的初始形态： I S Z J L T O
就在初始数据的数值状态设计
四格方块的下落计算：就是将每个格子的row+1
就是将下落的业务功能，转换为数字计算实现
左右移动
下落流程控制：控制方块下落与墙之间的控制关系
１ 合理的文字流程描述
２ 分析文字描述中的功能（动作）为方法
３ 用流程控制语句连接方法实现功能
4 严格测试结果！ＴestCase
左右移动流程控制
分数计算
界面的绘制
键盘事件控制
旋转流程控制
加速下降流程控制
开始流程控制（Ｔimer）
暂停流程控制
继续流程控制
结束流程控制
