井字游戲：Java

Question

我真的迷路了，我在構建這個游戲時遇到了麻煩。 我需要你們的幫助。 一直在努力解決這個問題好幾天了。 我有三個班級，Driver、Board 和 Player。 我有司機，我認為董事會在控制之下。 我主要是在玩家類上掙扎。 這樣做的目的是讓電腦玩家能夠隨機輸入數組，然后讓玩家能夠輸入他們想要玩的地方。

public class Driver
{
    public static void main(String[] args)
    {
        //new tic-tac-toe board
        Board board = new Board();

        //two new players (conputer and human)
        Player computer = new Player(board, "X");   //Give computer player access to board and assign as X.
        Player human = new Player(board, "O");      //Give human player access to board and assign as O.
        board.print();
        computer.computerMove();

        //while the game is not over
        while(!board.gameOver())
        {
            //let computer move first
            computer.computerMove();

            //print tic-tac-toe board
            board.print();

            //if the game is not over yet
            if (!board.gameOver())
            {
                //let the human make a move
                human.humanMove();

                //if the game is over
                if (board.gameOver())
                {
                    //print the board
                    board.print();
                }
            }
        } 

        //print out the winner (if there is one) of the game
        board.printWinner();
    }
}

板類

public class Board
{
    private String player = "X";
    private String cpu = "O";
    int row = 3;
    int column = 3;
    private String[][] theBoard = new String[row][column] ;

    public Board()
    {
        theBoard = theBoard;
    }

    public boolean gameOver()
    { 
       if  (theBoard[0][0] == player && theBoard[0][1] == player && theBoard[0][2] == player || // 1st row
            theBoard[1][0] == player && theBoard[1][1] == player && theBoard[1][2] == player || // 2nd row
            theBoard[2][0] == player && theBoard[2][1] == player && theBoard[2][2] == player || // 3rd row
            theBoard[0][0] == player && theBoard[1][0] == player && theBoard[2][0] == player || // 1st col.

            {
                return false;
            }
        else if (theBoard[0][0] == cpu && theBoard[0][1] == cpu && theBoard[0][2] == cpu || // 1st row
            theBoard[1][0] == cpu && theBoard[1][1] == cpu && theBoard[1][2] == cpu || // 2nd row
            theBoard[2][0] == cpu && theBoard[2][1] == cpu && theBoard[2][2] == cpu || // 3rd row
            theBoard[0][0] == cpu && theBoard[1][0] == cpu && theBoard[2][0] == cpu || // 1st col.
            theBoard[0][1] == cpu && theBoard[1][1] == cpu && theBoard[2][1] == cpu || // 2nd col.
            theBoard[0][2] == cpu && theBoard[1][2] == cpu && theBoard[2][2] == cpu || // 3rd col.
            theBoard[0][0] == cpu && theBoard[1][1] == cpu && theBoard[2][2] == cpu || // Diagonal          \ 
            theBoard[2][0] == cpu && theBoard[1][1] == cpu && theBoard[0][2] == cpu) //   Diagonal      /

            {
                return false;
            }
       else{

           return true;
        }
    }

    public void print()
    {

        System.out.println(theBoard[0][0] + " | " + theBoard[0][1]+ " | " + theBoard[0][2] + "\n----------");

        System.out.println(theBoard[1][0] + " | " + theBoard[1][1]+ " | " + theBoard[1][2] + "\n----------");

        System.out.println(theBoard[2][0] + " | " + theBoard[2][1]+ " | " + theBoard[2][2] + "\n");

    }

    public void printWinner()
    {
       if  (theBoard[0][0] == player && theBoard[0][1] == player && theBoard[0][2] == player || // 1st row
            theBoard[1][0] == player && theBoard[1][1] == player && theBoard[1][2] == player || // 2nd row
            theBoard[2][0] == player && theBoard[2][1] == player && theBoard[2][2] == player || // 3rd row

            theBoard[0][1] == player && theBoard[1][1] == player && theBoard[2][1] == player || // 2nd col.
            theBoard[0][2] == player && theBoard[1][2] == player && theBoard[2][2] == player || // 3rd col.
            theBoard[0][0] == player && theBoard[1][1] == player && theBoard[2][2] == player || // Diagonal          \ 
            theBoard[2][0] == player && theBoard[1][1] == player && theBoard[0][2] == player) //   Diagonal      /
            {
                System.out.println("X - won!");
            }
        else if (theBoard[0][0] == cpu && theBoard[0][1] == cpu && theBoard[0][2] == cpu || // 1st row
            theBoard[1][0] == cpu && theBoard[1][1] == cpu && theBoard[1][2] == cpu || // 2nd row
            theBoard[2][0] == cpu && theBoard[2][1] == cpu && theBoard[2][2] == cpu || // 3rd row
            theBoard[0][0] == cpu && theBoard[1][0] == cpu && theBoard[2][0] == cpu || // 1st col.
            theBoard[0][1] == cpu && theBoard[1][1] == cpu && theBoard[2][1] == cpu || // 2nd col.
            theBoard[0][2] == cpu && theBoard[1][2] == cpu && theBoard[2][2] == cpu || // 3rd col.
            theBoard[0][0] == cpu && theBoard[1][1] == cpu && theBoard[2][2] == cpu || // Diagonal          \ 
            theBoard[2][0] == cpu && theBoard[1][1] == cpu && theBoard[0][2] == cpu) //   Diagonal      /

            {
                System.out.println("O - won!");
            }


    }
}

而 Player 類，這是我最掙扎的一個。

import java.util.Scanner;
import java.util.Random;
import java.util.Arrays;
public class Player

{
    String player = "X";
    String cpu = "O";
    private Board ticTac;
    public static Scanner scan = new Scanner(System.in);
    public Player(Board board, String inBoard )
    {
        ticTac = board;
    }
public void randomPlace()
    {
        for(int i = 0; i < 3; i ++)
        {
            for(int j = 0; j < 3; j++)
            {

            }
        }
    }
    public void computerMove()
    {


    }        

    public void humanMove()
    {

    }
}

我想也許這可以幫助你。

import java.util.Scanner;
import java.util.Random;
import java.util.Arrays;
public class Player

{
    String player = "X";
    String cpu = "O";

    int row = 3;
    int column = 3;

    private Board ticTac;


    public static Scanner scan = new Scanner(System.in);
    public Player(Board board, String inBoard )
    {
        //here you have the board in player
        tictac = board;
    }

    public void computerMove()
    {   //here you can code something like this
        tictac.put(tictac.getRandomFreePlace(),cpu);
    }        

    public void humanMove(Position position)
    {
        tictac.put(position, human);
    }
}

你必須在 Board 中編寫 put(Position, String) 和 getRandomFreePlace()

然后掃描玩家移動並打印板。

哦，你要初始化你的板子嗎？ 你可以用 double for

  for(i=0;i<row;i++){
       for(j=0;j<column;j++){
        //here you can set the value you want
        theBoard[i][j]=0;
        }
    }

Answer 2

不知道我是否理解你的問題，你能重新表述一下或者舉個例子嗎？

據我了解，您希望在播放器類中使用您的棋盤方法是正確的嗎？

如果您創建了一個棋盤類並為其提供了所需的任何特征，那么在您的玩家類中，您可以創建一個新的“it”類，然后通過其名稱調用它以檢索您賦予它的任何特征。
