迷宫游戏就是玩家在地图中移动，移动至终点则游戏结束。

自己用文本文档手打了个小地图，0表示空白，1表示墙，文件名随意，我改成了map.MapData。然后程序里定义一个全局变量char Map[MapLenX][MapLenY];(长宽自定义)行为X，列为Y。定义char型常量RoadSymbol = '0', WallSymbol = '1', PlayerSymbol = '+'。

本游戏为面向对象编写的，所以就要设计一个类。数据需要一个坐标和一个bool型储存是否到达终点。所以自定义了个结构体储存坐标

struct point

{

int x, y;

};

还需要构造函数，析构函数，然后写个移动的函数PlayerMove()，再写个判断是否到达终点的函数CheckIfWin()。每走完一步就要刷新屏幕，所以还需要写个函数Refresh()，然后PlayerActor类就完成了。

class PlayerActor

{

public:

point m_Location;

bool m_IfWin;

PlayerActor();

~PlayerActor();

void PlayerMove(int _Direc);

void Refresh(void);

void CheckIfWin(void);

};

构造函数析构函数先不着急， 先定义一下PlayerMove()。思路是先判断是否可移动。若能，当前位置的地图标记设为RoadSymbol， 移动即更新坐标，新坐标位置在地图上标记为PlayerSymbol， 刷新画面，判断输赢。Refresh()思路为先用system("cls")清屏，然后逐行打印。若地图上某点为RoadSymbol输出空格， WallSymbol输出'*'， PlayerSymbol输出'+'。

接下来定义玩家起始位置和终点PlayerStart和PlayerEnd并初始化。main函数大体流程如下：读入地图，实例化PlayerActor，当!m_IfWin时接收键盘按键来移动，当m_IfWIn时弹出提示框并结束。所以还需要一个全局函数PlayerControl来接收按键并调用PlayerMove()。

至此，构造函数的流程也明确了。初始化m_IfWin和m_Location，在地图上表明玩家位置和重点位置，刷新屏幕，没了。然后再把能定义为常量的都定位常量，修改一下细节，就能得到一个简陋的走迷宫游戏了。
