如何在井字游戲中添加分數記錄系統 Java 游戲

Question

我正在使用 java netbeans 在 gui 中開發井字游戲，需要幫助添加多少個勝利“x”和“o”。 以下代碼是我目前用於該項目的唯一文件。 代碼本身的rest沒有問題，游戲按預期運行，只需要添加一個評分系統。 有什么想法可以實施評分系統嗎？

Answer 1

為此，您可以使用兩個整數來保存每個玩家的得分並以某種方式將它們顯示在屏幕上，為此我只是在控制台中打印了得分，但您可以做任何您喜歡的事情。 生成的打印消息是：

Current score:
X = 1 VS O = 0

繼承人的代碼：

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

然后在檢測到勝利時增加整數的值，我這樣做是在winEffect()方法中添加以下代碼行。 我還禁用了調用勝利時的按鈕，這樣即使游戲結束后你也不能繼續添加 Xs 或 Os，這也可以防止再次觸發該方法，這會再次增加分數。 我是我的 IDE 這顯示第 29 行，這是 winEffect 的結尾：

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，您需要在按下重新啟動按鈕時重新啟用按鈕，因此在您的jButtonReplayActionPerformed()方法中，我使用以下命令重新啟用它們，在我的 IDE 中顯示第 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);
    }
}

Answer 2

您可以通過JLabel和支持獲勝者邏輯的方法來執行此操作。

int xWinCount = 0;
int oWinCount = 0;

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

然后在你的winEffect方法中調用它，如下所示。

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

jLabelWinner在initComponent方法中定義如下

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

然后，將其添加到布局中。
