C++ 在类之间访问数据成员时出现问题

我有两个班；一个球员班和一个比赛班。我希望玩家能够使用其所有成员函数；携带、捕获等，但其成员函数需要了解匹配类数据成员；董事会、对手、挑战者，但不公开这些数据

如果你找不到一个好的解决方案或者对我的问题感到困惑，我仍然会对班级组织的建议感兴趣

mancala.h

#ifndef MANCALA_H
#define MANCALA_H

#include <string>
#include <random>

namespace mancala{  

    class player{
        public:
            void carry(int pit);
            void capture(const int& pit);
            bool madeStore(const int& pit)const;
            bool madeCapture(const int& pit)const; 
            bool madeValidMove(const int& pit)const;

    class match{
        public:
            match(const int& match_ID = 0) : board{4,4,4,4,4,4,0,4,4,4,4,4,4,0}{
                if(match_ID){
                    ;
                }
                else{
                    this->turn = randPlayer();
                    this->status = "make move";

让match类成为玩家类的朋友

C++中的一个朋友类可以访问它被声明为朋友的类的“私有”和“保护”成员。

void player::carry(int pit)
{
    if(this->madeValidMove(pit) == false){
        status = "invalid move";
    }
    else{

        int hand = board[pit];

        board[pit] = 0;

        for(hand; hand != 0; hand--){  

            if(pit == 13){
                pit = 0;
            }
            else{
                pit++;  
            }
             //Skips opponent store
            if(pit == 13 && turn == challenger){
                pit = 0;
            }//Skips challenger store
            else if(pit == 6 && turn == opponent){
                pit++;
            }
             //If placing last seed check where it is being placed
            if(hand == 1){
                 //Store
                if(this->madeStore(pit)){
                    board[pit]++;
                    status = "free move";
                }//Capture
                else if(this->madeCapture(pit)){
                    this->capture(pit);
                  nextTurn();
                }//Normal
                else{
                    board[pit]++;
                    nextTurn();
                }
            }//Placing seed
            else{
                board[pit]++;
            }
        }

        if(this->madeSideClear()){
            end();
        }
    }   

    save();
}
