本文介绍了一个使用C++实现的经典贪吃蛇游戏。该程序能够在DOS环境下运行，通过控制蛇头方向使蛇吃到豆豆并逐渐增长，同时避免碰到自身或墙壁。随着蛇的增长，游戏难度逐渐增加。

准备用cocos2d-x做一个经典的贪吃蛇游戏，先预热一下，用C++做个DOS的。

效果图如下：

现贴出完整代码：

#include <iostream>
#include "time.h"
#include "stdlib.h"
#include "conio.h"

using namespace std;

inline void display(char gsDomain[][22], int level, int moveSpeed)
{
	system("cls");       //清屏
	cout << endl << endl;
	for (int i = 0; i < 22; i++)
	{
		cout << "\t";
		for (int j = 0; j < 22; j++)
			cout << gsDomain[i][j] << " ";
		if (i == 0)
		{
			cout << "\tLevel：" << level;
		}
		else if (i == 3)
		{
			cout << "\t自动前进时间";
		}
		else if (i == 5)
		{
			cout << "\t间隔：" << moveSpeed << " ms";
		}

cout << endl;
	}
}

int main()
{
	char gsDomain[22][22];           //贪吃蛇活动区域(包括墙壁)
	//初始化贪吃蛇活动区域(不包括墙壁)
	for (int i = 1; i <= 21; i++)
	{
		for (int j = 1; j <= 21; j++)
			gsDomain[i][j] = ' ';
	}
	//初始化贪吃蛇活动区域的上下墙壁
	for (int i = 0; i < 22; i++)
		gsDomain[0][i] = gsDomain[21][i] = '-';
	//初始化贪吃蛇活动区域的左右墙壁
	for (int i = 1; i < 21; i++)
		gsDomain[i][0] = gsDomain[i][21] = '|';
	//初始化蛇身
	for (int i = 1; i <= 3; i++)
		gsDomain[1][i] = '*';
	//初始化蛇头
	gsDomain[1][4] = '#';

int snake[2][100];       //记录贪吃蛇每次出现的位置的坐标
	for (int i = 0; i < 4; i++)
	{
		snake[0][i] = 1;     //记录贪吃蛇所在位置的x坐标
		snake[1][i] = i + 1;  //记录贪吃蛇所在位置的y坐标
	}
	int head = 3, tail = 0, length = 4;

int beanX, beanY;        //豆豆出现的位置
	srand((unsigned)time(NULL));
	do
	{
		beanX = rand() % 20 + 1;
		beanY = rand() % 20 + 1;
	} while (gsDomain[beanX][beanY] != ' ');
	gsDomain[beanX][beanY] = '*';    //豆豆

cout << "\n\n\t\t贪吃蛇游戏即将开始!\n";
	long start;
	int level = 1, moveSpeed = 1000;
	for (int i = 3; i >= 0; i--)
	{
		start = clock();
		while (clock() - start <= 1000){}
		system("cls");
		if (i)
		{
			cout << "\n\n\t\t进入游戏倒计时：" << i << endl;
		}
		else
			display(gsDomain, level, moveSpeed);
	}

char direction = 77;           //贪吃蛇默认自动向右直线前进
	while (true)
	{
		bool timeFlag = true;
		int x, y;
		start = clock();

//若时间超过自动前进时间或者键盘上有键按下则终止循环
		while ((timeFlag = (clock() - start <= moveSpeed)) && !kbhit()){}

		{
			//键盘上有键按下时读取键盘输入
			getch();
			direction = getch();

			break;
		default: cout << "\tGame Over!\n";
			return 0;

if (x == 0 || x == 21 || y == 0 || y == 21)

			cout << "\tGame Over!\n";
			return 0;
		}

if (gsDomain[x][y] != ' ' && !(x == beanX && y == beanY))
		{
			//贪吃蛇的蛇头触碰到蛇身或者蛇尾
			cout << "\tGame Over!\n";
			return 0;
		}

if (x == beanX && y == beanY)

			//吃豆豆
			length++;      //长度加1
			if (length >= 8)

				//游戏升级处理
