c++实现2048游戏（控制台）

2048游戏的逻辑比较简单：同一行或者同一列的两个数字，如果值相同并且没有其他数字遮挡，则可以合并为一个数，并且不能连续合并。

刚开始写我考虑的主要是2048的逻辑部分，显示就先low low的用控制台好了，有兴趣的可以做下图形界面。

鉴于此，采用view-module分层模式将数据和表示层分离开来，这样之后就算修改了表示层代码，也不需要对数据层的代码做多少改动。

module 层代码：

#ifndef CGAME_H#define CGAME_H#include <windows.h>#include <String>#define ROW 4   //格子总行数#define COLUMN 4    //格子总列数class cGame{public:cGame();~cGame();void play();void moveUp();void moveDown();void moveLeft();void moveRight();void newLattice();bool canMove();void show();void buf_show();private:int(*matrix)[COLUMN];//存储格子信息int max;//格子最大的数字的值bool gameWin;//游戏是否取胜bool gameOver;//游戏是否结束};#endif // CGAME_H

Point 类是用来记录点坐标的，c++里面是有处理平面点坐标的方法的，不过我懒得找了就简单写了一个类，代码如下：

#pragma once#define NotPoint -1class Point{public:Point();~Point();void setPos(int x, int y);int x();int y();private:int xpos;int ypos;};

#include "Point.h"#include <iostream>using namespace std;Point::Point(){xpos = NotPoint;ypos = NotPoint;}Point::~Point(){}void Point::setPos(int x, int y){xpos = x;ypos = y;}int Point::x(){return xpos;}int Point::y(){return ypos;}

然后是main.cpp：

#include <iostream>#include "cGame.h"using namespace std;int main(){cGame cgame;while (1){cgame.play();cgame.show();Sleep(300);}return 0;}
