使用C语言实现贪吃蛇小游戏使用C语言实现贪吃蛇小游戏

本文实例为大家分享了C语言实现贪吃蛇小游戏的具体代码，供大家参考，具体内容如下
前言控制台的欢乐就是这么简单；
提示：以下是本篇文章正文内容，下面案例可供参考
一、贪吃蛇实现的结构和方式 1.用枚举定义蛇的移动方向

enum Dir{UP,DOWN,LEFT,RIGHT,//枚举不能用分号; }; //创建结构体，对蛇的参数进行设置；struct Snake{int size; //蛇的节数; int dir; //蛇的方向; int speed; //蛇的移动速度; //用数组来表示蛇的坐标; POINT coor[SNAKE_SIZE]; //蛇的最大节数; }snake; //食物的结构体；struct Food{int x; int y; int r; //食物半径; bool flag; //用来判断食物是否被吃; DWORD color; //食物颜色; }food;

# 2、使用步骤
## 1.引入库
代码如下（示例）：

```cimport numpy as npimport pandas as pdimport matplotlib.pyplot as pltimport seaborn as snsimport warningswarnings.filterwarnings('ignore')importsslssl._create_default_https_context = ssl._create_unverified_context

【使用C语言实现贪吃蛇小游戏】2.对窗口进行设置;
代码如下（示例）：

void GameDraw(){//双缓冲绘图; BeginBatchDraw(); //设置背景颜色; setbkcolor(RGB(28, 115, 119)); cleardevice(); //绘制蛇; setfillcolor(GREEN); //颜色的改变; for (int i = 0; i < snake.size; i++){solidcircle(snake.coor[i].x, snake.coor[i].y, 5); //solidcircle函数可以用来描绘无边框填充函数; }//绘制食物; if (food.flag){solidcircle(food.x, food.y, food.r); //solidcircle代表画圆; }EndBatchDraw(); }

3.对蛇进行初始化;

void GameInit(){//播放背景音乐; mciSendString("open./mp3.music alias BGM", 0, 0, 0); mciSendString("play BGM repeat", 0, 0, 0); initgraph(640, 480 /*SHOWCONSOLE*/); //设计随机数种子; srand(GetTickCount()); //GetTickCount()获取开机到现在的毫秒数; snake.size = 3; snake.speed = 10; snake.dir = RIGHT; for (int i = 0; i <= snake.size - 1; i++){snake.coor[i].x = 10 * (2 - i) + 20; //向右偏移; snake.coor[i].y = 10; //确保蛇在同一水品线; }//食物的初始化; 随机产生一个整数; 设置随机种子，头文件是stdlib.h; food.x = rand() % 640; food.y = rand() % 480; food.color = RGB(rand() % 256, rand() % 256, rand() % 256); //颜色值为0到256; food.r = rand() % 10 + 5; food.flag = true; }

二、源代码

#include#include#include//不是库函数; #include//随机数的产生; #include//导入背景音乐; #pragma comment(lib,"winmm.lib")//导入背景音乐; //结构体对snake初始化.#define SNAKE_SIZE 500/*typedef struct tagpoint{LONG x; LONG y; }POINT; *///用枚举表示蛇的方向; enum Dir{UP,DOWN,LEFT,RIGHT,//枚举不能用分号; }; //创建结构体，对蛇的参数进行设置；struct Snake{int size; //蛇的节数; int dir; //蛇的方向; int speed; //蛇的移动速度; //用数组来表示蛇的坐标; POINT coor[SNAKE_SIZE]; //蛇的最大节数; }snake; //食物的结构体；struct Food{int x; int y; int r; //食物半径; bool flag; //用来判断食物是否被吃; DWORD color; //食物颜色; }food; //数据的初始化; /*void GameInit(){//初始化graph图形窗口，SHOWCONSOLE控制台; initgraph(640, 480, SHOWCONSOLE); snake.size = 0; snake.speed = 10; snake.dir; snake.coor[0].x =10; snake.coor[0].y = 10; }*///数据的初始化; void GameInit(){//播放背景音乐; mciSendString("open./mp3.music alias BGM", 0, 0, 0); mciSendString("play BGM repeat", 0, 0, 0); initgraph(640, 480 /*SHOWCONSOLE*/); //设计随机数种子; srand(GetTickCount()); //GetTickCount()获取开机到现在的毫秒数; snake.size = 3; snake.speed = 10; snake.dir = RIGHT; for (int i = 0; i <= snake.size - 1; i++){snake.coor[i].x = 10 * (2 - i) + 20; //向右偏移; snake.coor[i].y = 10; //确保蛇在同一水品线; }//食物的初始化; 随机产生一个整数; 设置随机种子，头文件是stdlib.h; food.x = rand() % 640; food.y = rand() % 480; food.color = RGB(rand() % 256, rand() % 256, rand() % 256); //颜色值为0到256; food.r = rand() % 10 + 5; food.flag = true; }//绘制; void GameDraw(){//双缓冲绘图; BeginBatchDraw(); //设置背景颜色; setbkcolor(RGB(28, 115, 119)); cleardevice(); //绘制蛇; setfillcolor(GREEN); //颜色的改变; for (int i = 0; i < snake.size; i++){solidcircle(snake.coor[i].x, snake.coor[i].y, 5); //solidcircle函数可以用来描绘无边框填充函数; }//绘制食物; if (food.flag){solidcircle(food.x, food.y, food.r); //solidcircle代表画圆; }EndBatchDraw(); }//蛇的移动; //坐标的改变；void snakemove(){//让头部后面的跟着头走; for (int i = snake.size - 1; i > 0; i--){snake.coor[i] = snake.coor[i - 1]; }switch (snake.dir){case RIGHT:snake.coor[0].x += snake.speed; if (snake.coor[0].x - 10 >= 640){snake.coor[0].x = 0; }break; case LEFT:snake.coor[0].x -= snake.speed; if (snake.coor[0].x + 10 <= 0){snake.coor[0].x = 640; }break; case UP:snake.coor[0].y -= snake.speed; if (snake.coor[0].y + 10 <= 0){snake.coor[0].y = 480; }break; case DOWN:snake.coor[0].y += snake.speed; if (snake.coor[0].y - 10 >= 480){snake.coor[0].y = 0; }break; default:break; }}//通过按键改变蛇的方向; void KeyControl(){//判断有没有按键; if (_kbhit())//检测有没有按键，如果有就返回真，否则返回假; {//72 80 75 77上下左右键值; switch (_getch()){case 'w':case 'W':case 72:if (snake.dir != DOWN){snake.dir = UP; }break; case 's':case 'S':case 80:if (snake.dir != UP){snake.dir = DOWN; }break; case 'a':case 'A':case 75:if (snake.dir != RIGHT){snake.dir = LEFT; }break; case 'd':case 'D':case 77:if (snake.dir != LEFT){snake.dir = RIGHT; }break; case ' ':while (1){if (_getch() == ' '); return; }break; }}}//吃食物; void EatFood(){if (food.flag && snake.coor[0].x >= food.x - food.r && snake.coor[0].x <= food.x + food.r && snake.coor[0].y <= food.y + food.r && snake.coor[0].y >= food.y - food.r){snake.size++; food.flag == false; }if (!food.flag){food.x = rand() % 640; food.y = rand() % 480; food.color = RGB(rand() % 256, rand() % 256, rand() % 256); food.r = rand() % 10 + 5; food.flag = true; }}int main(){//init初始化graph ; initgraph(640, 480); //设置背景颜色; setbkcolor(RGB(28, 115, 119)); //设置背景绘图颜色; cleardevice(); GameInit(); while (1){snakemove(); GameDraw(); KeyControl(); EatFood(); Sleep(80); //时间延迟; }return 0; }
