Question

快速提问，我已经开发了3个A.I，每个都有不同的深度。

目前要选择你想要玩的A.I你必须进入名为Main.java的java文件并将其更改为你想要的任何一个。要改变的路线是：

chessGame.setPlayer(Piece.COLOR_BLACK, ai3);//Here A.I is assigned

我想让用户在游戏开始时有一个选项来选择A.I.我希望对界面有一些帮助，我在想像JOptionpane这样的东西可能有用。

（我只是不确定如何为A.I选择做一个）

目前A.I＆＃39>

AI1 AI2 AI3

package chess;
import chess.ai.SimpleAiPlayerHandler;

import chess.gui.ChessGui;
import chess.logic.ChessGame;
import chess.logic.Piece;


public class Main {

    public static void main(String[] args) {

        // Creating the Game 
        ChessGame chessGame = new ChessGame();

        // Creating the Human Player 
        //Human Player is the Object chessGui
        ChessGui chessGui = new ChessGui(chessGame);
        //Creating the A.I's
        SimpleAiPlayerHandler ai1 = new SimpleAiPlayerHandler(chessGame);//Super Dumb
        SimpleAiPlayerHandler ai2 = new SimpleAiPlayerHandler(chessGame);//Dumb
        SimpleAiPlayerHandler ai3 = new SimpleAiPlayerHandler(chessGame);//Not So Dumb

        // Set strength of AI, how far they can see ahead 
        ai1.maxDepth = 1;
        ai1.maxDepth = 2;
        ai3.maxDepth = 3;

        //Assign the Human to White 
        chessGame.setPlayer(Piece.COLOR_WHITE, chessGui);
        //Assign the not so dumb A.I to black 
        chessGame.setPlayer(Piece.COLOR_BLACK, ai3);

        // in the end we start the game
        new Thread(chessGame).start();
    }

}

感谢您的帮助。

您应该使用JComboBox来允许用户从3个可用选项中进行选择。如果您使用此JComboBox制作启动JFrame，则可以在之后创建主游戏帧并将其传递给JComboBox中的值。

例如，您可以让JComboBox提供设置Easy，Medium和Hard的难度选项。在JButton上使用动作侦听器从JComboBox获取所选值，并将其转换为适合您的minimax算法的int值。也就是说，传递1表示简单，2表示中等，3表示硬。

接下来更改你的ai类，使maxDepth在构造函数中。然后，当你实例化你的ai时，只需给它从前一帧向前传递的值，你就可以在正确的难度设置下创建你需要的唯一ai。

编辑：

看起来你设法得到类似的工作，这很棒！如果它对你有所帮助，我已经包含了一个简短的例子，说明我将如何在下面完成此操作。请注意，我还将其设置为使得SimpleAiPlayerHandler构造函数也采用int值来实例化maxDepth变量。你需要添加它。因为它使用我没有的类，所以我无法编译它。但是，如果其他人需要做类似的事情，只需删除DifficultyListener中的所有内容，除了print语句和从JComboBox中获得困难的行，你会看到它工作（和编译）。

import javax.swing.*;
import java.awt.event.*;

public class ChessSplash extends JFrame {
    private final JComboBox<Difficulty> difficultySetting;

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                ChessSplash gui = new ChessSplash();
                gui.setVisible(true);
            }
        });
    }

    public enum Difficulty {
        EASY(1, "Easy"), MEDIUM(2, "Medium"), HARD(3, "Hard");

        private final int intValue;
        private final String stringValue;

        private Difficulty(int intValue, String stringValue) {
            this.intValue = intValue;
            this.stringValue = stringValue;
        }

        @Override
        public String toString() {
            return stringValue;
        }
    };

    public ChessSplash() {
        super("Chess Game");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        difficultySetting = new JComboBox<>(Difficulty.values());
        JButton startButton = new JButton("Start Game");
        startButton.addActionListener(new DifficultyListener());
        JPanel mainPanel = new JPanel();
        add(mainPanel);
        mainPanel.add(difficultySetting);
        mainPanel.add(startButton);
        pack();
    }

    private class DifficultyListener implements ActionListener {
        @Override
        public void actionPerformed(ActionEvent e) {
            //Declare AI
            SimpleAiPlayerHandler ai;

            //Declare and Instantiate Chess Game
            ChessGame chessGame = new ChessGame();

            //Human Player is the Object chessGui
            ChessGui chessGui = new ChessGui(chessGame);
            //Assign Human Player to White
            chessGame.setPlayer(Piece.COLOR_WHITE, chessGui);

            //Get the selected difficulty setting
            Difficulty difficulty = (Difficulty)difficultySetting.getSelectedItem();

            //Instantiate Computer AI pass it the maxDepth for use in the constructor
            ai = new SimpleAiPlayerHandler(difficulty.intValue, chessGame);
            //Assign Computer Player to Black
            chessGame.setPlayer(Piece.COLOR_BLACK, ai);
            //Demonstrate the enum combobox works
            System.out.println(difficulty.intValue);

            //Dispose of the splash JFrame
            ChessSplash.this.dispose();

            //Start your game thread (I would probably do something to move this
            //onto the EDT if you're doing this is swing personally
            new Thread(chessGame).start();
        }
    }
}

需要帮助为用户功能添加难度选项
