Question

我正在制作一个完全图形化的战舰游戏，最终将允许2个玩家通过网络玩，但我很难弄清楚如何为网格上的每个方块分配坐标，以及如何让玩家选择他们想要的位置放船。香港专业教育学院制作船只.PNG都是相应的像素长度，以匹配100x100的正方形。（即）承运人需要5个方格。最后，我可以制作一个小弹出窗口，询问每个转弯时想要放置船的位置吗？我现在的代码非常小，它刚刚开始，但我需要一些帮助才能实现它。任何帮助表示赞赏。

首先，我建议不要让你的网格方块为100x100像素，因为这会导致网格为1000 x 1000，这对于许多屏幕来说太高了。对于您的gid，请考虑使用GridLayout，其中每个单元格为JButton。这是一个演示，看看它的外观：

public class GridTest extends JPanel implements ActionListener {

    public static void main(String[] args) {
        JFrame frame = new JFrame("Grid Test");
        frame.add(new GridTest());
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    }

    private void init() {
        GridLayout layout = new GridLayout(10, 10);
        setLayout(layout);
        for (char row = 'A'; row <= 'J'; row++) {
            for (int col = 1; col <= 10; col++) {
                JButton button = new JButton("" + row + col);
                button.setMargin(new Insets(0, 0, 0, 0));
                button.setPreferredSize(new Dimension(50, 50));
                button.addActionListener(this);
                add(button);
            }
        }
    }

    public GridTest() {
        init();
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        JOptionPane.showMessageDialog(this, String.format("You pressed %s!", e.getActionCommand()),
                "You Pressed a Button", JOptionPane.INFORMATION_MESSAGE);
        ((JButton) e.getSource()).setEnabled(false);
    }
}

我建议查找Swing并查看所有组件以了解每个组件的功能。 Oracle's Tutorial是一个很好的起点
