一、贪吃蛇小游戏简介：
用上下左右控制蛇的方向，寻找吃的东西，每吃一口就能得到一定的积分，而且蛇的身子会越吃越长，身子越长玩的难度就越大，不能碰墙，也不能咬到自己的身体，等到了一定的分数，就能过关。
二、函数框架
三、数据结构
typedef struct Snake { size_t x; //行 size_t y; //列 struct Snake* next; }Snake, *pSnake;
定义蛇的结构体，利用单链表来表示蛇，每个结点为蛇身体的一部分。
四、代码实现（vs2010 c语言）
1.Snake.h
#ifndef __SNAKE_H__ #define __SNAKE_H__ #include <stdio.h> #include <stdlib.h> #include <Windows.h> #include <time.h> #include <malloc.h> #include <assert.h> //标识地图大小 #define ROW_MAP 10 //地图的行 #define COL_MAP 20 //地图的列 #define SUCCESS_SCORE 10//通关分数 enum Direction //蛇行走的方向 { R, //右 L, //左 U, //上 D //下 }Direction; enum State { ERROR_SELF, //咬到自己 ERROR_WALL, //撞到墙 NORMAL, //正常状态 SUCCESS //通关 }State; typedef struct Snake { size_t x; //行 size_t y; //列 struct Snake* next; }Snake, *pSnake; void StartGame(); void RunGame(); void EndGame(); #endif
2.Snake.c
#include "Snake.h" pSnake head = NULL; //定义蛇头指针 pSnake Food = NULL; //定义食物指针 int sleeptime = 500;//间隔时间，用来控制速度 int Score = 0; //总分 int everyScore = 1; //每步得分 //定义游戏中用到的符号 const char food = '#'; const char snake = '*'; void Pos(int x, int y) //控制输出光标 { COORD pos; //pos为结构体 pos.X = x; //控制列 pos.Y = y; //控制行 SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), pos);//读取标准输出句柄来控制光标为pos } void Face() { system("color 0C"); printf("*******************************************************\n"); printf("* Welcome to Snake Game!
