在Java下棋,我想移动棋子

Making a chess game in Java, I want to move the pieces

所以我将图像存储为 JButton 上的 ImageIcon。我希望用户单击他们想要使用的片段的 JButton,然后单击另一个 JButton 将其移动到那里,我该怎么做?

我试过使用 actionListener 来获取 ImageIcon,但事实证明它非常复杂,尤其是因为我有一个 JButton 图像的二维数组。

ActionListener actionListener = new ActionListener() {
            public void actionPerformed(ActionEvent actionEvent) {

                System.out.println(actionEvent.getActionCommand());

            }
        };

        JButton[][] squares = new JButton[8][8];
        Border emptyBorder = BorderFactory.createEmptyBorder();

        for (int row = 0; row < squares.length; row++) {
            for (int col = 0; col < squares[row].length; col++) {

                JButton tempButton = new JButton();

                tempButton.setBorder(emptyBorder);
                tempButton.setSize(64, 64);


                squares[row][col] = tempButton;
                squares[row][col].addActionListener(actionListener);
                panel.add(squares[row][col]);

                squares[0][0].setIcon(new ImageIcon(BoardGUI.class.getResource("castle.png"), "castle"));



            }
        }

试试下面的代码。我不知道在 JButtons 上使用 ImageIcons 的确切代码,但这让我明白了:

JButton pieceToMoveButton = null;   //variable that persists between actionPerformed calls

public void actionPerformed(ActionEvent actionEvent)
{
    JButton button = (JButton)actionEvent.getSource();

    if (pieceToMoveButton == null)    //if this button press is selecting the piece to move
    {
        //save the button used in piece selection for later use
        pieceToMoveButton = button;
    }
    else        //if this button press is selecting where to move
    {
        //move the image to the new button (the one just pressed)
        button.imageIcon = pieceToMoveButton.imageIcon
        pieceToMoveButton = null;    //makes the next button press a piece selection
    }
}

不确定这是否是您要查找的内容,但这是将 JButton 的位置移动到另一个位置的一种方法: 现在作为一个例子,假设已经有代码声明和初始化一个 JButton(JButton thatotherbutton = new JButton 等)。将它移动到某个位置可以这样完成:

Rectangle rect = thatotherbutton.getBounds();
xcoordinate = (int)rect.getX();
ycoordinate = (int)rect.getY();
chesspiecebutton.setBounds(xcoordinate, ycoordinate, xlengthofbutton, ylengthofbutton);

使用这些坐标来设置您的 JButton 在单击另一个 JButton 时的新边界(换句话说,位置)。
