【问题描述】：

我正在使用 gui 中的 java netbeans 开发井字游戏，需要帮助添加“x”和“o”获得了多少胜利。以下代码是我目前用于该项目的唯一文件。其余代码本身没有问题，游戏按预期运行，只需要添加一个评分系统。有什么想法可以实施评分系统吗？

  package game;

嗯，首先你需要一些变量来跟踪评分信息；其次，您需要添加一些代码，以便在游戏结束时适当地更新这些变量；第三，您需要在 GUI 上的某个位置提供显示评分信息。

标签： java netbeans

【解决方案1】：

您可以通过JLabel 和支持获胜者逻辑的方法来做到这一点。

int xWinCount = 0;
int oWinCount = 0;

private void incrementWinner( String winner )
{
    if( "X".equals( winner ) )
    {
        xWinCount += 1;
    }
    else
    {
        oWinCount += 1;
    }
}

然后在您的winEffect 方法中调用它，如下所示。

    incrementWinner( b1.getText() );
    jLabelWinner.setText( "X wins : " + xWinCount + " | O wins : " + oWinCount );

jLabelWinner 在initComponent 方法中定义如下

jLabelWinner = new javax.swing.JLabel();
jLabelWinner.setFont( new java.awt.Font( "Tahoma", 1, 18 ) );
jLabelWinner.setText( "Win Status" );

然后，将其添加到布局中。

样式和重置由您决定。这是做你想做的事情的一种方式

【解决方案2】：

为此，您可以使用两个整数来保存每个玩家的得分并以某种方式将它们显示在屏幕上，为此我只是在控制台中打印了得分，但您可以做任何您喜欢的事情。生成的打印消息是：

Current score:
X = 1 VS O = 0

代码如下：

//Add the two integers to hold them, in my IDE this shows line 14
int xScore = 0, oScore = 0;

然后当检测到胜利时增加整数的值，我这样做是在您的 winEffect() 方法中添加以下代码行。我还在调用胜利时禁用了按钮，这样即使游戏结束后你也无法继续添加 Xs 或 Os，这也防止了再次触发该方法，这会再次增加分数。我的 IDE 这显示第 29 行，这是 winEffect 的结尾：

if (b1.getText().equals("X")) xScore++;
else if (b1.getText().equals("O")) oScore++;

for (Component comp : jPanel2.getComponents())
    if (comp instanceof JButton)
        comp.setEnabled(false);

System.out.printf("Current score:\n X = %d VS O = %d\n\n", xScore, oScore);

之后，您需要在按下重新启动按钮时重新启用按钮，因此在您的 jButtonReplayActionPerformed() 方法中，我使用以下命令重新启用它们，在我的 IDE 中显示第 309 行：

for(Component comp : comps){
    if(comp instanceof JButton){
        JButton button = (JButton)comp;
        button.setText("");
        button.setBackground(Color.WHITE);
        jLabelMSG.setText("Start");
        button.setEnabled(true);
    }
}
