目录1. 概述..................................................1. 概述这次实训，目的以VS 为环境，利用MFC，使用C++语言编写一个简单的飞机大战游戏。

实现的主要功能：1.有开始游戏界面，上下左右键控制飞机自由移动，空格键发射炮弹。

2.设有关卡，每打完一个boss就会过关，每过一关战机炮弹会升级，敌机随机发射子弹数量增加。

3.战机起始十条命，可以通过过关和吃到道具增加血量。

4.战机子弹打中敌机，敌机就会爆炸，boss血量随关卡升高而增多，打败敌机或者boss会有分数加成。

5.设有无敌模式和普通模式，无敌模式大招无限，生命无限，战机导弹直接升至最高等级。

2. 相关技术碰撞检测用CRect类的GetRect()函数可以获得当前对象的矩形区域, IntersectRect()并用此函数判断二者是否碰撞。

CObList链表这个程序使用CObList链表来存储各效果。

CobList类似于一个双向链表，POSITION 类型的变量为链表的键。

使用POSITION变量，既可以作为链表循环中的循环变量，也可以作为标记某个位置的标签。

我们可以通过获得某元素的POSITION来访问它。

本程序中主要用到的函数有：GetHeadPosition（）：获取链表首元素的POSITION；AddTail（）：将新的元素添加到链表最后；GetNext( POSITION& rPosition )：使rPosition指向下一个元素。

设置定时器SetTimer()函数来设置定时器。

背景滚动为了让游戏场景更加逼真，游戏节奏更加合理，可以通过让背景滚动来提高游戏的场景效应，实现这一技术时，可以将一张背景图片复制为2张，从上到下连续的拼接在一起，使其不会出现图片的卡顿和瞬移现象。

内存释放技术这个程序中有大量的地方需要使用内存，如果不及时删除会出现闪图等情况，容易导致程序崩溃，要及时释放内存资源。

3. 总体设计与详细设计系统模块划分主要功能模块4. 编码实现{{}}}}ddTail(new CEnemy);}nCreator--;ddTail(new Cda);count++;}ddTail(new Cshengming);count++;}ddTail(new Cboss);bxt = 1;bn++;}if (level == 2&&bn==0&&count>=50&&count<=52) {m_ObjList[enboss].AddTail(new Cboss);bxt = 1;bn++;}if (level == 3&&bn==0&&count>=75&&count<=77) {m_ObjList[enboss].AddTail(new Cboss);bxt = 1;bn++;}if (level == 4&&bn==0&&count>=100&&count<=102) {m_ObjList[enboss].AddTail(new Cboss);bxt = 1;bn++;}if (level == 5&&bn==0&&count>=150&&count<=152) {m_ObjList[enboss].AddTail(new Cboss);bxt = 1;bn++;}if (level>5&&count%200==0&&bn==0){m_ObjList[enboss].AddTail(new Cboss);bxt = 1;bn++;}if (m_pMe == NULL)return;ddTail(new CBomb + 20, + 10));}if (level == 2 && wu == 0){m_ObjList[enBomb].AddTail(new CBomb + 10, + 30));m_ObjList[enBomb].AddTail(new CBomb + 30, + 30));}if (level == 3 && wu == 0){m_ObjList[enBomb].AddTail(new CBomb + 10, + 30));m_ObjList[enBomb].AddTail(new CBomb + 30, + 30));m_ObjList[enBomb].AddTail(new CBomb + 20, + 30));
