我正在开发一款游戏，它有很多连接在一起的类。工作正常，但现在一切都崩溃了。

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
我虽然在某个地方有一个不匹配的支架，或者一个缺失;在课程结束时，但我确实检查了代码中的每一个，所以我认为我已经排除了这一点。
从第一个错误开始：
1>c:\users\ronan\desktop\c++\razoo\razoo\player.h(21): error C2143: syntax error : missing ';' before '*'
以及它指向的代码：
#ifndef PLAYER_H
#define PLAYER_H
#include <string>
#include <fstream>
#include "Room.h"
#include "Inventory.h"
#include "Array.h"
class Player
{
private:
string m_name;
int m_health;
int m_confidence;
int m_humor;
int m_speed;
Room* m_currentRoom; //Line 21
Inventory m_inventory;
我认为#include "Room.h"无法正常工作？
我是否混淆了某种循环依赖（我现在甚至都不完全理解它们）？
或者还有其他一些“常见”问题可以同时调用所有这些错误吗？
这里的第一篇文章，所以不确定你是否需要更多代码或任何东西（或者如果我搞砸了任何合成器！）
谢谢！
答案 0 :(得分：0)
您可以通过从“Player.h”中删除#include "Room.h"并用以下内容替换该行来解决循环依赖关系：
class Room;
这样可以正常工作，因为看起来你只使用指向Room类的指针。 在Player.cpp中，如果你需要Room的方法和成员，或者你曾经取消引用指针，你可以在顶部执行此操作：
#include "Player.h"
#include "Room.h"
如果这不起作用，您可以发布更多代码吗？
