1.  在ZorkUL.h文件中设置vector型room变量，存储类型为room *指针型，为了和房间号匹配

   vector<Room *> room;

    

2. 新建房间 ，并且把房间号存入room数组中，使用push_back函数；

3. 修改房间相关变量，走向和地图

   void ZorkUL::createRooms()  {
       Room *a, *b, *c, *d, *e, *f, *g, *h, *i,*j,*k;
   
   	a = new Room("a");
           a->addItem(new Item("x", 1, 11));
           a->addItem(new Item("y", 2, 22));
   
       b = new Room("b");
           b->addItem(new Item("xx", 3, 33));
           b->addItem(new Item("yy", 4, 44));
   
       c = new Room("c");
       d = new Room("d");
       e = new Room("e");
       f = new Room("f");
       g = new Room("g");
       h = new Room("h");
       i = new Room("i");
       j = new Room("j");
           j->addItem(new Item("xxx",111, 111));
           j->addItem(new Item("yyy",222, 222));
       k = new Room("k");
   
   //             (N, E, S, W)
   	a->setExits(f, b, d, c);
   	b->setExits(NULL, NULL, NULL, a);
   	c->setExits(NULL, a, NULL, NULL);
       d->setExits(a, e, j, i);
   	e->setExits(NULL, NULL, NULL, d);
   	f->setExits(NULL, g, a, h);
   	g->setExits(NULL, NULL, NULL, f);
   	h->setExits(NULL, f, NULL, NULL);
       i->setExits(NULL, d, NULL, NULL);
       j->setExits(d, k, NULL, NULL);
       k->setExits(NULL, NULL, NULL, j);
   
       room.push_back(a);
       room.push_back(b);
       room.push_back(c);
       room.push_back(d);
       room.push_back(e);
       room.push_back(f);
       room.push_back(g);
       room.push_back(h);
       room.push_back(i);
       room.push_back(j);
       room.push_back(k);
   
       currentRoom = a;
   }

4.  添加teleport命令，修改currentroom的值，使用random函数随机生成房间号下标，跳转到随机房间

CommandWords::CommandWords() {
	// Populate the vector if we haven't already.
	if (validCommands.empty()) {
		validCommands.push_back("go");
		validCommands.push_back("quit");
		validCommands.push_back("info");
		validCommands.push_back("map");
		validCommands.push_back("take");
		validCommands.push_back("put");
        validCommands.push_back("teleport");
	}
}

else if(commandWord.compare("teleport") == 0){
        int r=rand()%11;
        currentRoom=room[r];
        cout << currentRoom->longDescription() << endl;
    }
