這篇文章主要為大家詳細介紹了C++控制臺實現(xiàn)貪吃蛇，文中示例代碼介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了C++實現(xiàn)貪吃蛇游戲的具體代碼，供大家參考，具體內(nèi)容如下

剛學完了C語言，便嘗試的寫了貪吃蛇的代碼，但是效果不佳，很多的bug，所以，這個學了C++，便重新的寫了這個小游戲，用類來封裝！

先是頭文件：

struct Snake
{
 int x, y;
};
class snake
{
public:
 snake()    //構(gòu)造函數(shù)
 {
 length = 3;
 s[2].x = 10;
 s[2].y = 10;
 s[1].x = 9;
 s[1].y = 10;
 s[0].x = 8;
 s[0].y = 10;
 up = right = left = down = 0;
 }
 ~snake(){}
 void display();  //顯示蛇身函數(shù)
 void Rightmove();  //右移函數(shù)
 void Leftmove();  //左移函數(shù)
 void Upmove();   //上移函數(shù)
 void Downmove();  //下移函數(shù)
 int cheak();   //檢查是否撞墻或撞到自身
 void creat_food();  //產(chǎn)生食物
 int eat_food();  //吃食物
private:
 struct Snake s[100]; //先定義蛇身最長100
 int length;   //當前蛇長度
 int x3, y3;   //食物坐標
 int up, down, right, left; //蛇的狀態(tài)，是上移還是下移或...
};
 
void make_frame();  //打印框架的函數(shù)
void show();   //游戲開始倒計時函數(shù)
void gameover();  //游戲結(jié)束函數(shù)

下面是各個函數(shù)的實現(xiàn)的cpp文件：

# include <iostream>

# include <time.h>
# include "snake.h"
# define MaxLen 20

void gotoxy(HANDLE hOut, int x, int y)   //輸出位置的函數(shù)
{
 COORD pos;
 pos.X = x;
 pos.Y = y;
 SetConsoleCursorPosition(hOut, pos);
}
 
void snake::display()      //打印蛇身
{
 for (int i = length - 1; i >= 0; i--)
 {
 if (i == length - 1)    //打印蛇頭
 {
 gotoxy(hOut, s[i].x, s[i].y); 
 cout << char(15);
 }
 else        //打印蛇身
 {
 gotoxy(hOut, s[i].x, s[i].y);
 cout << '*';
 }
 }
 gotoxy(hOut, 0, 22);
}
void snake::Rightmove()     //右移
{
 right = 1; up = down = left = 0;
 int x1, x2, y1, y2;
 x1 = x2 = s[length - 1].x;
 y1 = y2 = s[length - 1].y;
 s[length - 1].x++;      //蛇頭x坐標自增
 for (int i = length - 2; i >= 0; i--)  //除了蛇頭，其他的結(jié)點都等于它的上一個結(jié)點的坐標
 {

 s[i].x = x1; s[i].y = y1;

下面是游戲的截圖：

控制臺的實現(xiàn)，不是很美觀，主要是由于上下和左右的間隙不一樣大，所以看起來不是很好看，但總體還是實現(xiàn)了貪吃蛇！
