Question

所以我对编程比较陌生，我正在尝试创建一个基本的跳棋游戏。我现在遇到的麻烦是当我点击我的一个包含一块我需要的JButton基本上用一个替换它在它的特定位置的新按钮。到目前为止，我已经删除了所说的JButton，但没有用新的代码取代它。

在将它应用到整个电路板之前，我一直试图在0,0件上实现这一点。

 public class checkersBeBitchin extends JFrame{
JButton[][] squares = new JButton[8][8];
Container box = getContentPane();
int[][] pieceTracker = new int[8][8];
JPanel board = new JPanel();

/**
 * @param args
 */
public static void main(String[] args) {
    checkersBeBitchin begin = new checkersBeBitchin();

}

public checkersBeBitchin(){
    box.setLayout(new BorderLayout());
    makeBoard();
    setVisible(true);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setLocationRelativeTo(null);
    setSize(600,600);
    setTitle("Checkers");

我不会添加/删除按钮，而是在模型中保持正方形的状态。通过这样做，您可以切换知道其新状态的任何方块的状态。

public class MyCheckerSquare extends JButton {
    private CheckerPiece presentPiece;

    public MyCheckerSquare(Color background) {
        super();

        setBackground(background);
    }

    public void setCheckerPiece(CheckerPiece piece) {
        presentPiece = piece;
        // Change the icon regarding the given piece
    }
}

public enum CheckerPiece {
    BLACK, RED
}

所有的棋子都会由另一个类处理，而不是控制器。
