今天小编给大家分享一下怎么使用C语言实现贪吃蛇小游戏的相关知识点，内容详细，逻辑清晰，相信大部分人都还太了解这方面的知识，所以分享这篇文章给大家参考一下，希望大家阅读完这篇文章后有所收获，下面我们一起来了解一下吧。
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）：
```c
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
import warnings
warnings.filterwarnings('ignore')
import ssl
ssl._create_default_https_context = ssl._create_unverified_context2.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;
}#include<stdio.h>
#include<conio.h>
#include<graphics.h>//不是库函数;
#include<stdlib.h>//随机数的产生;
#include<mmsystem.h>//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;
