我不知道如何描述它,但是我声明了一个类(movableBox),但无法在特定范围内使用(该范围在类播放器中)。

这是我的一些代码:

玩家等级:

#ifndef PLAYER_H
#define PLAYER_H

#include <SFML/Graphics.hpp>
#include <vector>
#include "movablebox.h"

class player
{
    public:
        sf::RectangleShape* player;
        sf::Texture* playerTexture;
        sf::Vector2f speed;
        bool touching;

        static void create(sf::Vector2f pos_);
        static void draw(sf::RenderWindow& window);
        static void updatePos(float& dt, float gravity, std::vector<sf::RectangleShape*> solids, std::vector<movableBox::movableBox_*> movableBoxes);
        static void checkControls();
        static void checkControlsperEvent (sf::Event& event);
};

#endif // PLAYER_H


和movingBox类:

#ifndef MOVABLEBOX_H
#define MOVABLEBOX_H

#include <SFML/Graphics.hpp>
#include <vector>
#include "player.h"

class player;

class movableBox
{
    public:

        struct movableBox_ {
            sf::RectangleShape* box;
            sf::Texture* texture;
            sf::Vector2f speed;
            bool selected;
            player* selectedBy;
            bool touching;
        };

        static void create(sf::Vector2f pos_, sf::Vector2f size_);
        static void draw(sf::RenderWindow& window);
        static void updatePos(float& dt, float gravity, std::vector<sf::RectangleShape*> solids);
        static void grabNearest(player* player);
};

#endif // MOVABLEBOX_H


我收到此错误:

CodeBlocksProjects/phys/player.h:18:110: error: ‘movableBox’ was not declared in this scope


如您所见,我缺乏解释,我不知道为什么或如何发生,我希望您理解我的问题。
提前致谢! :)

最佳答案

这是一个循环依赖性问题。在#include "movablebox.h"中有player.h,在#include "player.h"中也有movablebox.h

您已经在player中转发了movablebox.h类,这似乎足够了;因此只需从#include "player.h"中删除​​movablebox.h

关于c++ - 类未在作用域中声明,但已声明该类,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/46620778/
