java - 纸牌游戏中的玩家顺序

Question

我的玩家顺序有问题。我需要第一个玩家成为该轮的获胜者。所以我有四个按钮，有可能阻止错误玩家的移动，比如“不是你的回合，玩家二是第一个，因为是上一轮的获胜者”

我怎样才能控制它？最终验证的方法

我有四个牌标签，每个玩家手上有五张牌

对于每个按钮，设置我做的对应卡

//PLAYER1
    //card1 
    ActionListener one = new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            if (gr.getCounter1() < 5) {
                gr.setCounter1(gr.getCounter1() + 1);
                test1.setIcon(play1a);
                pn1.setText(Integer.toString(play2a));
                pn5.setText(play3a);
                pn50.setText(play4a);
            } else {
                pn5.setText("No more cards");
            }
        }
    };

    arraybtn[1].addActionListener(one);
    arraybtn[1].setPreferredSize(new Dimension(120, 20));

    play1a = gr.GameRules1().getImage(); //image of card
    play2a = gr.GameRules2(); // value
    play3a = gr.GameRules3(); // king of hearts for exemple
    play4a = gr.GameRules4(); // hearts

    arraybtn[1].setText(gr.GameRules3()); // button name

你们的类(class)有多少个类(class)？希望它有一个驱动 GUI 的非 GUI 模型，并且应该是这个完全相同的模型来决定游戏的控制。我不会像本线程中的一位海报所建议的那样抛出错误，而是使用游戏 Controller 模型只允许正确的玩家玩。 GUI 将通过禁用所有不应按下的按钮并仅启用应按下的按钮来反射(reflect)这一点。如何在代码中实现这一点取决于您当前程序的代码和整体结构。

编辑:补充答案

不确定你是否还在，但这里有一个快速拼凑起来的例子来说明我的意思。 GamePlayer 类(显然)代表游戏的玩家，并且有一个字段 myTurn，仅当轮到该玩家时才为 true，并且该字段具有关联的 void setMyTurn(boolean) 方法和 boolean isMyTurn() 方法。/p>

GameModel 类有一个名为players 的 GamePlayer 数组，一个允许其他类获取数组中每个 Player 的 getPlayer(int) 方法，一个表示当前轮到的玩家数组中索引的playerTurnIndex 以及一个 advancePlay() 方法，该方法增加此索引(按玩家数组的长度进行修改，以便它环绕)，然后循环遍历玩家数组，根据 playerTurnIndex 值为每个玩家设置 myTurn 字段。

GameGui 类有一个名为 gameModel 的 GameModel 字段，并保存 JButton 的集合(实际上是一个 HashMap)，在每个按钮的 ActionPerformed 方法中，调用模型的 advancePlay() 方法，并调用一个名为 enablePlayerTurns() 的私有(private)方法根据模型中相应播放器的值启用或禁用播放器 JButton:

import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import java.util.Map;

import javax.swing.*;

public class GamePlayMain {
    private static void createAndShowUI() {
        String[] players = {"John", "Bill", "Frank", "Henry"};
        GameModel model = new GameModel(players);
        GameGui gui = new GameGui(model);

        JFrame frame = new JFrame("GamePlayMain");
        frame.getContentPane().add(gui);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                createAndShowUI();

        players = new GamePlayer[playerNames.length];

        }
        players[0].setMyTurn(true);
