c++，很多错误.也许是循环依赖

C++ , Lots of Errors. Maybe Circular Dependency?

本文关键字：循环 依赖 也许 错误 c++      更新时间：2023-10-16

我正在制作一款游戏，它有一堆类链接在一起。本来很好，但现在一团糟。

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

我想我有一个不匹配的大括号，或者缺少一个;但是我确实检查了代码中的每一个错误，所以我认为我已经排除了这个问题。

从第一个错误开始:

1>c:usersronandesktopc++razoorazooplayer.h(21): error C2143: syntax error : missing ';' before '*'

和它指向的代码:

    #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;

在我看来，#include "Room.h"不能正常工作?
我是否混淆了某种循环依赖关系(我现在甚至不完全理解它们)?
或者是否有其他一些"常见"问题会同时引发所有这些错误?
在这里的第一个帖子，所以不确定你是否需要一些更多的代码或任何东西(或者如果我搞砸了任何语法!)
谢谢!

您可以通过从"Player.h"中删除#include "Room.h"并将该行替换为以下内容来解决循环依赖:

class Room;

这将工作得很好，因为它看起来你只使用一个指向Room类的指针。在player。cpp中，如果你需要Room的方法和成员或者你需要解引用指针，你可以在顶部这样做:

#include "Player.h"
#include "Room.h"

如果这不起作用，你能发布更多的代码吗?
