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;

# 二、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_context

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;
}

利用学会的知识做点小游戏

提示：这里对文章进行总结：
例如：以上就是今天要讲的内容，本文仅仅简单介绍了pandas的使用，而pandas提供了大量能使我们快速便捷地处理数据的函数和方法。
