java - 井字游戏按钮颜色

我一直在更新我在网上找到的有点过时的 tic tac toe 代码(就像它现在实际工作一样:P)我已经快完成了，但我仍然遇到同样的问题。井字棋板内的 3x3 按钮工作完美，除了一件事，单击它们后的颜色始终是背景，我已尝试更正此问题，但它所做的只是使按钮根本不改变颜色。这两种颜色是红色和绿色，我希望这样当每个玩家单击一个按钮时它会更改为他们的颜色。

主要游戏代码:

最佳答案

除了您使用的是黄色而不是红色之外，该代码没有任何问题 - 如果您想更改它，只需将所有出现的 Color.YELLOW 更改为 Color.RED，并交换两个玩家的颜色以保持一致性:

p1namel = new JLabel("");
p1namel.setText(p1);
p1namel.setFont(textfont);
p1namel.setForeground(Color.GREEN); // << HERE
getContentPane().add(p1namel);

p2namel = new JLabel("");
p2namel.setText(p2);
p2namel.setForeground(Color.RED); // << AND HERE
p2namel.setFont(textfont);
getContentPane().add(p2namel);

当我在它的底部添加一些支持代码以使框架运行时:

public static void main(String[] args) {
    java.awt.EventQueue.invokeLater(new Runnable() {
        public void run() {
            TicTacToeGame frame = new TicTacToeGame("pax","diablo");
            frame.setVisible(true);
        }
    });
}

它看起来工作正常(除了不匹配的颜色):

通过如上所示进行更改，您最终得到:
