即時通訊從房間從文本文件，並嘗試使用變量中的信息，所以我後我把信息添加到一個linkedList，搜索房間，我想要的房間ID，然後使用setRoomName =到它找到名稱的房間。但這不是工作...任何人都可以看到這個問題？setRoomName不改變變量roomName
這裏是我的代碼：
#include "Rooms.h"
#include "DoublyLinkedList.h"
#include <string>
using namespace std;
DoublyLinkedList<Rooms> roomsList;
DoublyLinkedListIterator<Rooms> itr = roomsList.getIterator();
Rooms :: Rooms()
{
this->roomID = 0;
this->roomName = "";
this->roomExits = "";
}
Rooms :: Rooms(int roomID,string roomName,string roomExits)
{
this->roomID = roomID;
this->roomName = roomName;
this->roomExits = roomExits;
}
int Rooms :: getRoomID()
{
return roomID;
}
void Rooms :: setRoomID(int roomID)
{
this->roomID = roomID;
}
string Rooms :: getRoomName()
{
return roomName;
}
void Rooms ::setRoomName(string roomName)
{
this->roomName = roomName;
}
string Rooms :: getRoomExits()
{
return roomExits;
}
void Rooms :: setRoomExits(string roomExits)
{
this->roomExits = roomExits;
}
void Rooms :: loadRooms()
{
string fileName = "Rooms\\Rooms.txt";
ifstream infile(fileName);
string garbage;
int loadRoomID;
string loadRoomName1;
string loadRoomName2;
string loadRoomExits;
while(infile >>garbage >> garbage >> loadRoomID >> garbage >>
garbage >> garbage >> loadRoomName1 >> loadRoomName2 >> garbage
>> garbage >> loadRoomExits)
{
cout << "Room ID: \t\t"<< loadRoomID << "\n";
cout << "Room Name: \t\t"<< loadRoomName1 <<" " << loadRoomName2 << "\n";
cout << "Room Exits: \t\t" << loadRoomExits <<"\n";
string loadRoomName = loadRoomName1 + loadRoomName2;
Rooms r1 (loadRoomID,loadRoomName,loadRoomExits);
roomsList.Append(r1);
}
}
void Rooms :: printRooms()
{
int index = 0;
//Loop through the iterator.
for(itr.Start();itr.Valid();itr.Forth())
{
index++;
cout << "------------------Rooms------------------\n";
cout << "--------------------------------\n";
cout << "Position:\t\t" << index << "\n";
cout << "--------------------------------\n";
cout << "Room ID:\t\t" << itr.Item().getRoomID() << "\n";
cout << "Room Name:\t\t" << itr.Item().getRoomName() << "\n";
cout << "Room Exits:\t\t" << itr.Item().getRoomExits() << "\n";
cout << "------------------------------------------\n";
}
cout << "Rooms: \t\t" << roomsList.getCount() << "\n";
}
string Rooms :: searchByRoomID(int searchByID)
{
//Loop through the Iterator.
for (itr.Start(); itr.Valid(); itr.Forth())
{
//If the object entered has the same first name as the one in the loop.
if (itr.Item().getRoomID() == searchByID)
{
//Print out the details from the list.
cout << "------------------------------------------\n";
cout << "Room ID:\t\t" << itr.Item().getRoomID() << "\n";
cout << "Room Name:\t\t" << itr.Item().getRoomName() << "\n";
cout << "Room Exits:\t\t" << itr.Item().getRoomExits() << "\n";
cout << "------------------------------------------\n";
setRoomID(itr.Item().getRoomID());
setRoomName(itr.Item().getRoomName());
setRoomExits(itr.Item().getRoomExits());
cout << getRoomID();
cout << getRoomName();
cout << getRoomExits();
}
}
return getRoomName();
}
任何幫助將不勝感激。
