c语⾔贪吃蛇详解3.让蛇动起来c语⾔贪吃蛇详解3.让蛇动起来前⼏天的实验室培训课后作业我布置了贪吃蛇，今天有时间就来写⼀下题解。
我将分⼏步来教⼤家写⼀个贪吃蛇⼩游戏。
由于⼤家c语⾔未学完，这个教程只涉及数组和函数等知识点。
上次我已经教⼤家画出蛇了，现在我就教⼤家让蛇动起来。
为了让⼤家更好理解，蛇的移动就⽤最简单的办法，这⾥就不⽤链表，顺序队列什么的了。
蛇的移动就是头往前移动，然后后⾯的⾝体移动到前⼀节⾝体原来的位置上。
就像这样： int i;for(i=sLength-1;i<1;i--) //从尾巴开始，每⼀个点的位置等于它前⾯⼀个点的位置{s[i][0]=s[i-1][0];s[i][1]=s[i-1][1];}那蛇头怎么办呢？为了确定蛇头的位置，我们定义⼀个变量原来存储蛇现在的⽅向。
int direction; //蛇的⽅向我们可以通过direction的值来标记现在蛇的⽅向。
⽐如0代表上，1代表下。
为了⽅便，我们定义⼀些常量//定义direction的每个值代表的⽅向#define UP 0#define DOWN 1#define LEFT 2#define RIGHT 3这样，我们就可以这样写switch(direction){case UP:s[0][0]--;break;case DOWN:s[0][0]++;break;case LEFT:s[0][1]--;break;case RIGHT:s[0][1]++;break;}写好的move函数如下void move(){int i;for(i=sLength-1;i>0;i--) //从尾巴开始，每⼀个点的位置等于它前⾯⼀个点的位置{s[i][0]=s[i-1][0];s[i][1]=s[i-1][1];}switch(direction){case UP:s[0][0]--;break;case DOWN:s[0][0]++;break;case LEFT:s[0][1]--;break;case RIGHT:s[0][1]++;break;}}然后move写好了，我们还要写个循环，这样就可以让蛇⼀直动了。
C语⾔⼿把⼿教你实现贪吃蛇AI（中）⼿把⼿教你实现贪吃蛇AI，具体内容如下1. ⽬标这⼀部分主要是讲解编写贪吃蛇AI所需要⽤到的算法基础。
2. 问题分析贪吃蛇AI说⽩了就是寻找⼀条从蛇头到⾷物的⼀条最短路径，同时这条路径需要避开障碍物，这⾥仅有的障碍就是蛇⾝。
⽽A star 算法就是专门针对这⼀个问题的。
在A star 算法中需要⽤到排序算法，这⾥采⽤堆排序（当然其他排序也可以），如果对堆排序不熟悉的朋友，请移步到这⾥——，先看看堆排序的内容。
3. A*算法A star(也称A*)搜寻算法俗称A星算法。
这是⼀种在图形平⾯上，有多个节点的路径，求出最低通过成本的算法。
常⽤于游戏中对象的移动计算上。
A* 算法是⼀种启发式搜寻算法，有别于DFS， BFS搜索。
可以这样理解“启发式”的涵义，⽐如从起点A到达⽬的地B的路线，并不是直接告诉你，从A出发，向东⾏驶200⽶，右转进⼊XX路，直⾏500⽶到达B；⽽是从A出发，直⾏，直到遇到第⼀家肯德基，右转直到看到B⼤厦。
⽽A*算法中⽤来启发的线索就是移动成本，也就是权重。
3.1 移动成本如下图所⽰，从A点出发，可以有四个⽅向可⾛（由于贪吃蛇仅仅可以⾛上下左右四个⽅向，所以这⾥不考虑⾛斜线的情况），假设每个⽅向移动⼀格的成本为10，A*算法中采⽤的F值来评价移动成本，F=G+H。
假设节点C是待考察的⼀个点，G 代表的是从起点A到C的移动成本，如下图的情况G=10。
那么H代表的就是从C点到⽬标B点的移动代价的预估值，如下图的情况H=50，那么F=60。
为什么说是预估，因为现在对于从C点到B点的情况还不清楚，因为中间可能存在障碍物，那么实际的移动代价就会⼤于预估的情况。
⽽对于待考察点D，其F=80，显然在C 和D点中（当然这⾥待考察的点不⽌C和D点），A*算法会选择C点。
3.2 算法流程图4. 源代码代码中假定起始点A(5,10)，⾷物B(5,15)，如下图。
其中‘X'代表障碍物，‘O'代表的就是寻找到的从A到B的路径。
完整版C语言贪吃蛇设计思路和代码详解到了本章，你已经学完了大部分C语言的基础知识，详细讲解贪吃蛇代码的条件就具备了。
本教程教你编写的贪吃蛇不依赖TC环境，不依赖任何第三方库，可以在VC 6.0、VS等常见IDE中编译通过，请看下图:更多效果图请查看:游戏初始化、游戏进行中、游戏结束。
请大家先把贪吃蛇的源码下载下来浏览一下，我们再具体分析，这样将会有更好的效果。
贪吃蛇源代码下载:提取密码:81qm贪吃蛇设计思路上图中的红色空心方框(?)表示边框，是贪吃蛇的边界，贪吃蛇不能碰到它，否则就“死掉”，游戏结束。
绿色实心方框(?)表示贪吃蛇的活动范围，贪吃蛇可以自由移动，食物(苹果)也会随机出现在这个区域。
我们不妨将贪吃蛇的活动范围称为“贪吃蛇地图”，而加上边框就称为“全局地图”。
我们需要记录地图中每一个节点的信息，包括:位置:也就是第几行几列;类型:这个节点出现的是贪吃蛇、食物、边框，还是什么都没有(绿色的背景)。
索引:也就是数组下标，稍后会说明是什么意思。
所以需要定义一个结构体二维数组:struct{char type;int index;}globalMap[MAXWIDTH][MAXHEIGHT];用一维下标和二维下标表示位置;用 type 表示类型，不同的类型用不同的数字代表;用 index 表示索引。
直观上讲，应该将 type 定义为int类型，不过int占用四个字节，而节点类型的取值范围非常有限，一个字节就足够了，所以为了节省内存才定义为char类型。
同时，再建立一个足够大的一维数组，让贪吃蛇在数组内活动:struct{int x;int y;} snakeMap[ (MAXWIDTH-2)*(MAXHEIGHT-2) ]x、y 表示行和列，也就是 globalMap 数组的两个下标。
globalMap 数组中的索引 index 就是 snakeMap 数组的下标。
globalMap 表示了所有节点的信息，而 snakeMap 只表示了贪吃蛇的活动区域。
