Windows 版贪吃蛇 -- 编程驿站-- 编程爱好者博客

Windows 版贪吃蛇－－我的第一个windows 程序一：游戏共六个界面，默认界面如下：二：游戏简介 1）该游戏界面共提供了六个，您可以自己修改界面。 2）游戏在老版贪吃蛇有了更新，提供了各种不同的果实，不同果实有不同的作用，详情请看“帮助”菜单里的“游戏规则”，或者在游戏区点击右键，选择“游戏规则”。 3）为了提高趣味兴，游戏设置了七个级别，每升一级，改变蛇的颜色并自动切换下一个界面。三：游戏的实现方法该游戏虽然是用 C++写的，但并没有用MFC，只是调用了一些API函数其中蛇的移动，以及果实的随机产生，均使用定时器，另外蛇的喷火功能也是用定时器实现的，本来是用多线程，但是多线程就是在优先级最低的情况下运行也超快，如果要用空循环来延时倒不如定时器来的简洁。游戏主要参考了skyblue 的 <<Visual C++经典游戏程序设计>> 但是却又有本质上的不同，主要不同如下： 1）类的封装方法，skyblue 的程序设计了两个类，我的设计了三个 (snake,fruit,interface),skyblue 的全局变量太多，而我只设计了一个 interface 类的全局对象 2）从 bitmap 文件里提取资源，在 skyblue 里的实现非常机械，而我用一个枚举简洁的实现，并且在位图内容布局改变的情况下，只需修改少量代码。 3）蛇的移动算法实现也不同，skyblue 用动态内存，个人认为他的实现方法非常笨拙，^_- 由于本人缺少美术修养，“蛇”就取自 skyblue，界面不是很好，本想找几张绚丽的图片做为开始和结束，但是没找到合适的，我的搞不出来的 ^_^,就随便取了几种颜色，呵呵！！！代码很长，下面是三个类的接口代码：（中英文杂糅的注释希望不会给您的阅读带来不便） // interface.h: interface for the CInterface class.// ////////////////////////////////////////////////////////////////////// #ifndef _CINTERFACE_H_#define _CINTERFACE_H_ #include <windows.h> #define VBLOCK_TOTAL 28#define HBLOCK_TOTAL 28 #define IDT_SNAKE_MOVE WM_USER // “蛇”移动定时器 #define IDT_FRUIT_SET WM_USER+1 // 产生“水果”定时器#define IDT_FIRE_MOVE WM_USER+2 // 喷火时火种移动定时器 #define IDM_GAME_START WM_USER+3 // 画刷数量，其实就是界面数量，与磁盘位图文件有关#define MAX_BRUSH 6 // 定义“墙”,“空”，这两个值必须不在枚举类型：BMP_POS,EnumFoodType中#define BLOCK_WALL 1000#define BLOCK_NONE 1001 #define MAX_FIRE 10 // 屏幕上同时出现的最多火种数目 // 贪吃蛇移动一步的结果#define MOVE_HIT_WALL 100#define MOVE_GET_FRUIT 101#define MOVE_COMMON 102#define MOVE_WIN_GAME 103 #define MOVE_LOST_GAME 104#define MOVE_PAUSE 105#define MOVE_HIT_BODY 106 // 快捷键对应的虚键码#define ID_START_GAME 0X53#define ID_PAUST_GAME 0X44#define ID_EXIT VK_ESCAPE#define ID_SOUND_SWITCH 0X46#define ID_USER_FACE 0X47#define ID_DEFAULT_FACE 0X48#define ID_LOW_SPEED_FRUIT 0X42#define ID_FIRE_FRUIT VK_SPACE#define ID_RESTART_GAME 0X52 #include "Fruit.h" #include "snake.h" #define MAX_FIRE 10 // 一次能同时喷出火的最大数目 // “火”的数据结构struct FIRETYPE{ // 起始喷火位置 UINT xStart, yStart;
