根据错误提示应该是少了大括号，你仔细查一下吧！

括号我都检查了好几遍了

//room6.h

#ifndef ROOM6_H
#define ROOM6_H
#include "room.h"
class room6:public room
{
public:
    room6()
    {
        getname("funroom");
        set_exits();
    }
    void set_exits()
    {
        exits_num = 3;
        exits[0] = "east";
        exits[1] = "west";
        exits[2] = "down";
    }
    friend void play_game();
};/////////////////////////////////////////////////这里少！！！！！
#endif

在//paly_game.cpp中
case 8:

            pt = new room8;
            pt->show();
            room8.show();//////////////////////明显多了这句///////////

你自已一下看符不符合你要求，我也要仔细研究一下这代码，写得很不错，呵呵！！！

记得很早以前有个朋友在这里问了关于做R PG的问题,和这个差不多。当时我帮他想的是做任意房间怪物的,但是还很不完善,研究下你的代码。
P.S.可不可以打个包放在1楼呢?那样会方便很多的。3Q

研究中
