c++ - 比较两个对象之间的实例。 C++

Question

我目前正在创建一个设计糟糕的 Battleship 游戏，我已经到了一个地步，我无法确切地弄清楚如何从另一个对象访问一些数据。

我有一个棋盘类，它创建两个大小为 100 的数组。我有一个玩家类，它有一个属于他们的两个棋盘的实例(他们的棋盘和敌人的棋盘(命中，未命中，空))

我遇到的麻烦是弄清楚如何让两个玩家板同步，但在板的功能内，内部玩家......

我的功能应该是脱离板的，这样

 class Board{
    int playerBoard[100];
    int enemyBoard[100];

    int makeMove(Move)
      {
        // compare player1.enemyBoard to player2.playerBoard (THIS ??)
      };

 class Player{
    Board playerBoards;

    void makeMove() // edit, the makeMove() in players, cant have parameters
    {
    playerBoards.makeMove(Move x){...};
    };
 }

 Player player1;
 Player player2;

player1.makeMove(Move x);

但是在 player1.boards 的函数中，我如何到达 player2 ...我很困惑，任何帮助将不胜感激。对于这可能造成的任何混淆，我深表歉意。

你可以像下面的方案一样实现

class Board{
      private:
        int player1Board[100];
        int player2Board[100];
      public:
        int* getPlayerBoard(int playerID){
            if (playerID == 1)
                 return &player1Board;
            else if (playerID == 2)
                 return &player2Board;
            else
                 return nullptr;
        }
        int makeMove(Move,int playerID)
        {
           if(playerID == 1){
              //update player1Board
           }
           elseif (playerID == 2){
              //update player2Board
           }
       };

class Player{
    private:
       Board* playerBoards;
       int playerID;

    public:
       Player(int _playerID, Board* _playerBoards){
          playerID = _playerID;
          playerBoards = _playerBoards;
       }
       void makeMove() // edit, the makeMove() in players, cant have parameters
       {
          playerBoards->makeMove(Move x,playerID){...};
       };        
 }

 Board playerBoards;
 Player player1(1,&playerBoards);
 Player player2(2,&playerBoards);

 player1.makeMove(Move x);

要进一步改进它，您也可以对类 Board 使用单例模式
