c语言链表贪吃蛇脚本之家,C++控制台实现贪吃蛇游戏
本文實例為大家分享了C++實現貪吃蛇游戲的具體代碼，供大家參考，具體內容如下
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() //構造函數
{
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
void Rightmove(); //右移函數
void Leftmove(); //左移函數
void Upmove(); //上移函數
void Downmove(); //下移函數
int cheak(); //檢查是否撞墻或撞到自身
void creat_food(); //產生食物
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，是上移還是下移或...
};
void make_frame(); //打印框架的函數
void show(); //游戲開始倒計時函數
void gameover(); //游戲結束函數
下面是各個函數的實現的cpp文件：
# include
# include
# include
# include "snake.h"
# define MaxLen 20
# define MaxWen 30
using namespace std;
HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE); //獲取句柄

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，其他的結點都等于它的上一個結點的坐標

下面是游戲的截圖：
控制臺的實現，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，但總體還是實現了貪吃蛇！
