本文实例讲述了贪吃蛇游戏C++命令行版的实现代码，是非常经典的游戏。分享给大家供大家参考。具体实现方法如下：

众所周知，贪吃蛇游戏是经典的计算机游戏。

游戏描述如下：

1. 贪吃蛇可以自动直线前进，或者玩家可以通过方向键操纵贪吃蛇上下左右前进，每次前进一格。
2. 贪吃蛇在规定的区域内活动，当：

①贪吃蛇触碰到墙壁时；

②贪吃蛇的蛇头触碰到蛇身或者蛇尾时；

③玩家的键盘输入不是方向键时；

命令行显示“Game Over!”并且退出游戏。

3. 贪吃蛇活动的区域内每次随机产生一颗“豆豆”，当贪吃蛇吃到“豆豆”后蛇身增长一格，自动前进时间缩 短100ms(默认是1000ms，且不能少于100ms)。贪吃蛇长度每为8的倍数Improve a Level。

C++代码如下：

#include <bios.h>#include <conio.h>#include <dos.h>#include <graphics.h>#include <stdlib.h>#include <time.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(time(0));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;}elsedisplay(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()){}if (timeFlag){//键盘上有键按下时读取键盘输入getch();direction = getch();}switch (direction){//向上case 72: x = snake[0][head] - 1, y = snake[1][head];break;//向下case 80: x = snake[0][head] + 1, y = snake[1][head];break;//向左case 75: x = snake[0][head], y = snake[1][head] - 1;break;//向右case 77: x = snake[0][head], y = snake[1][head] + 1;break;default: cout << "\tGame Over!\n";return 0;}if (x == 0 || x == 21 || y == 0 || y == 21){//贪吃蛇触碰到墙壁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1if (length >= 8){//游戏升级处理length -= 8;level++;if (moveSpeed > 100)moveSpeed -= 100;}gsDomain[snake[0][head]][snake[1][head]] = '*';gsDomain[x][y] = '#';head = (head + 1) % 100;snake[0][head] = x;snake[1][head] = y;do{beanX = rand() % 20 + 1;beanY = rand() % 20 + 1;} while (gsDomain[beanX][beanY] != ' ');gsDomain[beanX][beanY] = '*';display(gsDomain, level, moveSpeed); //屏幕上显示}else{//不吃豆豆gsDomain[snake[0][tail]][snake[1][tail]] = ' '; //蛇尾前移一格tail = (tail + 1) % 100;gsDomain[snake[0][head]][snake[1][head]] = '*';head = (head + 1) % 100;snake[0][head] = x;snake[1][head] = y;gsDomain[x][y] = '#'; //蛇头前移一格display(gsDomain, level, moveSpeed); //屏幕上显示}}return 0;}
