无法从Object Array

Question

我目前正在制作Line3类型的游戏，我在尝试交换数组中的两个对象时遇到问题。我的游戏有两个类：Gem类，你必须排队获得点和Board类，它包含一个Gem数组​​[6] [6]。

问题在于我的交换方法。在方法内部，我有一些cout来帮助我看到并且交换实际上已完成，但我认为我在副本上执行此操作后，当我刷新我的板时，Gems不会互换。这是我的代码，随时提出任何建议：

Board.h

#pragma once
#include "Gem.h"

    class Board
    {
    public:
        Board();
        ~Board();

        void gameLoop();
        void refreshGameGrid();
        void refillGameGrid();
        void checkIfStacks();
        void swapGems(Gem& p_firstGem, Gem& p_secondGem);
        Gem getGem(int line, int column);

    private:
        Gem m_gameGrid[6][6];
    };

Board.CPP

// Swap the position of two Gems on the Board.
    void Board::swapGems(Gem& p_firstGem, Gem& p_secondGem)
    {
        cout <<"Avant : " << p_firstGem.getRepresentation() << " | " << p_secondGem.getRepresentation() << endl;
        p_firstGem.switchWith(p_secondGem);
        cout << "Après : " << p_firstGem.getRepresentation() << " | " << p_secondGem.getRepresentation() << endl;
    }

Gem.h

#pragma once
#include "gemMania.h"

class Gem
{
public:
    Gem();
    ~Gem();

    // Getters
    const string& getRepresentation();
    const string& getColor();
    const string& getPosition();
    int getNumberOfGems();

    // Setters
    void setColorAndRepr(const string&, const string&);
    //Methods
    void switchWith(Gem&);
    void destroyGem();
    void renewGem();

private:
    string m_representation;
    string m_color;
    string m_position;
    static int numberOfGems;

};

Gem.cpp

// Switch the attrbutes of two gems, hence swaping the two of them.
void Gem::switchWith(Gem& p_otherGem)
{
    swap(this->m_color, p_otherGem.m_color);
    swap(this->m_representation, p_otherGem.m_representation);
}

非常感谢所有愿意花时间帮助我的人！
