用mfc设计贪吃蛇游戏源代码,最好有解析

1.算法

1. 首先,用一个结构体数组来标记蛇的X位置和Y位置,还有每一节的方向。用一变量标识蛇的长度。

2. 在蛇非转弯的移动时用定时器来自动移动,不管蛇是哪种形状,都只需在每次移动时先将各节向后移动(蛇尾舍弃,新的蛇尾由蛇尾的上一节代替):如蛇本身为snake[0]到snake[3],就是将snake[0]到snake[2]一起移动到snake[1]到snake[3]: 将 snake[2]的XY坐标赋值snake[3]的XY坐标 ,snake[1]的XY坐标 赋值给snake[2]的XY坐标 ,snake[0]的XY坐标 赋值给snake[1]的XY坐标 。再判断蛇头的方向,然后将蛇头顺着这个方向向前移动一格就是蛇头snake[0]的XY坐标 。而蛇除蛇头外各节的方向由函数SetDirection()来确定(明显此种情况,蛇头的方向不变),SetDirection()的思想是根据蛇的每一节的前一节的相对位置来确定本节的方向。(其实这个函数是多余的,真正用到的只有蛇头的方向)。

3. 蛇在转弯时,也是各节一次向后移,蛇头的位置顺着转弯的方向移动,方向由转弯方向确定。

4. 蛇在吃到食物时,长度加一,蛇头的位置变成食物的位置,方向不变。蛇的本身每节的XY位置都向后移。如蛇本身为snake[0]到snake[3], 就是将snake[0]到snake[3]一起移动到snake[1]到snake[4]。

5. 基于对话框的应用程序,响应按键消息需在PreTranslateMessage里,而不是像文档视图模式那样在OnKeyDown里响应。

6. 每次蛇在转弯时只能有一种方向按键能响应,即要么左右转,要么上下转。蛇头方向向左或向右时,只能上下转微信小游戏贪吃蛇源码;蛇头方向向上或向下时,只能左右转。

7. 食物的位置由rand函数随机产生。

2.添加如下函数和变量

1 void HuaFangGe(int bianChang, int gridShumu); //如在400*400的方格里绘制20*20个格子,则bianChang = 400;gridShumu = 20;

2 void InitSnackSite(); //初始化蛇的位置

3

4 int snakeLength; //表示蛇的长度

5 int foodX; //食物的X位置

6 int foodY; //食物的Y位置

7 bool start; //标志是否开始

8 bool reStart; //标志是否重新开始

9

10 struct SNAKE

11 {

12 int x;

13 int y;

14 char direction; //某位置的方向为前一个位置相对于该位置的方向,由SetDirection()确定

15 }snake[200];

16

17 void DrawRed(int x, int y); //指定点0*0到20*20,画相应颜色,下同(红头绿身蓝尾)

18 void DrawGreen(int x, int y);

19 void DrawBlue(int x, int y);

20 void DrawBlack(int x, int y); //根据SetFoodXY()所确定的foodX和foodY来画食物。

21

22 void DrawSnakeFood(); //根据数组snakeSite数组的标识信息类绘制蛇的形状位置颜色。

23 void SetFoodXY(); //随机绘制食物的XY位置

24

25 bool leftRight; //确定是否能上下走(蛇本身在上下走,再按上下就无用微信小游戏贪吃蛇源码了)

26 bool upDown; //确定是否能左右走(蛇本身在左右走,再按左右就无用了)

27

28 void MoveSite(); //蛇移动过程中,设置“除蛇头”外各节的x和y的位置,顺序前移。

29 void SetDirection(); //蛇移动过程中,设置“除蛇头”外各节的方向

30

31 void TurnLeft(); //当蛇左转时

32 void TurnRight(); //当蛇右转时

33 void GoUp(); //当蛇向上时

34 void GoDown(); //当蛇向下时

求一段JAVA编写的贪吃蛇小程序源代码

用MVC方式实现的贪吃蛇游戏,共有4个类。运行GreedSnake运行即可。主要是观察者模式的使用,我已经添加了很多注释了。

1、

/*

* 程序名称:贪食蛇

* 原作者:BigF

* 修改者:algo

* 说明:我以前也用C写过这个程序,现在看到BigF用Java写的这个,发现虽然作者自称是Java的初学者,

* 但是明显编写程序的素养不错,程序结构写得很清晰,有些细微得地方也写得很简洁,一时兴起之

* 下,我认真解读了这个程序,发现数据和表现分开得很好,而我近日正在学习MVC设计模式,

* 因此尝试把程序得结构改了一下,用MVC模式来实现,对源程序得改动不多。

* 我同时也为程序增加了一些自己理解得注释,希望对大家阅读有帮助。
