1、C+课程设计打砖块游戏MFC课程设计说明书设计题目： 打砖块游戏 所属系部： 计算机工程系 专 业： 计算机科学与技术 学 号： XXXX XXX 姓 名： XXXX 指导教师： XXXX 设计日期： 12-26 一、 设计任务1.1 任务描述使用MFC框架设计一个打砖块游戏。在客户区内显示砖块分布，小球和托盘。按空格键开始游戏，Esc键结束游戏。开始游戏小球可以跳起来打砖块，移动鼠标实现托盘的移动，打到的砖块消失。如果托盘没有接到小球，那么生命值减一，共有三次生命，生命都用完时，可以继续或结束。1.2 设计要求1. 自定义屏幕二维坐标系：x轴水平向右为正，y轴垂直向上为正，坐标系原点位于客户

2、区中心。2. 新加上两个类Brick类和Baffle类，分别用来定义并绘制砖块和托盘。3. 使用定时器函数控制小球的运动。4. 使用双缓冲技术实现动画。5. 在TestView类中实现砖块的分布6. 添加函数实现小球各种的碰撞速度大小和方向的改变。7. 添加函数实现鼠标移动控制托盘。1.3 效果图设计效果图如图1所示。图1 小球打砖块效果图二、 设计思路本设计首先构建双缓冲框架，小球和砖块、客户区边界发生碰撞后，改变运动方向。设置游戏关卡并绘制砖块分布。鼠标移动控制托盘。托盘没有接住小球，生命值则减一。游戏结束时显示对话框以便继续或退出游戏。三、 关键源代码及注释3.1 关于窗口外观设计的代码
