我正在为我的高中cpt制作连接四。到目前为止，我已经显示了所有内容，但它的胜利检查引起了问题。游戏板上的点是由连接四板上的空点和填充点的单独图像创建的。当跑动并选择点时，轮到他们时自动黄色获胜(颜色为红色和黄色)。感谢您的帮助，如果您还有任何疑问，请询问。

Answer 1

您忘记将“Yellow win”放入if block 内。这就是为什么它总是显示

此外，您还可以查找按钮的索引，因此不必复制并粘贴类似的代码块

首先声明一个列表

static List<JButton> buttonz = Arrays.asList(
    firstButton, secondButton, thirdButton, fourthButton, 
    fifthButton, sixthButton, seventhButton);

然后在按钮处理程序内部查找

private static class ButtonHandler implements ActionListener {
    public void actionPerformed(ActionEvent e) {
        //which button?
        int buttonIndex = buttonz.indexOf(e.getSource());

        //drop box, check win and show message 
        if (redTurn) {
            dropRedBox(buttonIndex);
            if (winCheck("red")) {
                JOptionPane.showMessageDialog(null, "Red wins!", "Winner!", JOptionPane.INFORMATION_MESSAGE);
            }
        } else {
            dropYellowBox(buttonIndex);
            if (winCheck("yellow"))
                JOptionPane.showMessageDialog(null, "Yellow wins!", "Winner!", JOptionPane.INFORMATION_MESSAGE);
        }
    }
}
