MyBlock实验报告文档

1、一 需求分析1. 设计目的用C#语言编写一个俄罗斯方块游戏，要能够实现俄罗斯方块的全部功能（即控制游戏开始、暂停、结束，控制（或通关后）方块下降的速度，记分功能，游戏帮助，计算游戏时间等。2. 系统设计要求用visual studio .net 2003/2005编写，能在windows 2000及以上操作系统平台上运行。游戏界面友好，编码简洁，稳定，高效。二 总体设计建立正方形类(class square)，用四个小正方形组合成俄罗斯方块的七种形状。用一窗口(class form1：form)作为游戏界面，用工具箱画出游戏功能需要的控件。建立游戏背景类(class gamefield)，用于

2、初始化游戏背景和方块颜色，计算游戏得分并消行。建立方块类(class block)，实现俄罗斯方块的七种形状，以及他们的移动方向，旋转。游戏界面类负责实现事件的触发和显示游戏时间。帮助窗口(class help)提示玩家怎样操作俄罗斯方块。三 详细设计 系统功能模块图初始化界面窗口并开始计时帮助菜单控制菜单游戏设置菜单操作说明退出慢快较快非常快出较慢退出速度设置类的成员列表： Class square: /组合俄罗斯方块的小正方形 public Point location; /小正方形左上角的坐标 public Size size; /小正方形的大小 public Color foreCol
