游戏抽奖对话框的重复实例

Question

我一直在做一个关于零和十字的项目。我曾经遇到一个令人恼火的问题。当只剩下一个按钮可用，并且到目前为止还没有检测到获胜的走法时，作为一个玩家，我点击这个按钮，游戏应该会提示这是一个平局。出现一个对话框，当我单击“确定”时，同样的对话框再次出现。在我看来，这是一个无限循环。提前感谢

// make random move if above rules dont apply

Random rand1 = new Random();
Random rand2 = new Random();

int max = 2;
int min = 0;

int randnum1 = rand1.nextInt((max - min) + 1) + min ;
int randnum2 = rand2.nextInt((max - min) + 1) + min ;    

while( MadeMove == false) {
    while( true ) {

        if( !SecondTest.cells[randnum1][randnum2].getText().equals(SecondTest.ComputerMark) && !SecondTest.cells[randnum1][randnum2].getText().equals(SecondTest.PlayerMark))
        {
            SecondTest.cells[randnum1][randnum2].setText(SecondTest.ComputerMark);
            MadeMove = true; 

            if ( SecondTest.CheckDraw()) {
                break;
            }
            break;  
        } else {
            System.out.println("occupied");

            randnum1 = rand1.nextInt((max - min) + 1) + min ;
            randnum2 = rand2.nextInt((max - min) + 1) + min ;

            if (SecondTest.CheckDraw()) {
                break;
            }

        }
    }
}    


public static boolean CheckDraw()
{
    boolean GameDraw = true;


    for ( int i = 0; i<3; i++) {
        for ( int j = 0; j<3; j++) {
            if (cells[i][j].getText().equals(".")) {
                GameDraw = false;
            }
        }
    }


    if ( GameDraw == true  ) {
        DrawCounts++;
        JOptionPane.showMessageDialog (null, "Oh no, it's a draw! " +
                " Total Player Wins : " + PlayerCounts + " " +
                " Total Computer Wins : " + ComputerCounts + " " +
                " Total Draw Counts : " + DrawCounts + " "                  
                , "Oh no, it's a draw!", JOptionPane.INFORMATION_MESSAGE);
        jTextArea2.setText("It is a draw!\n To start a new game,please press Reset\n");
        gameOver = true;
        PlayerGame = false;
        AIGame = false;
        return true;
    }
    return false;

}

你的内部循环的意义是什么？当然，您希望随机尝试移动，直到MadeMove为真或检测到抽签。您还希望将随机数生成移动到循环中，以减少重复。类似地，将draw in if和else的检查合并为一个检查。这应该是有效的，除非随机移动获胜！

while( MadeMove == false) {
    randnum1 = rand1.nextInt((max - min) + 1) + min ;
    randnum2 = rand2.nextInt((max - min) + 1) + min ;

    if( !SecondTest.cells[randnum1][randnum2].getText().equals(SecondTest.ComputerMark) && !SecondTest.cells[randnum1][randnum2].getText().equals(SecondTest.PlayerMark)) {
        SecondTest.cells[randnum1][randnum2].setText(SecondTest.ComputerMark);
        MadeMove = true; 
    } else {
        System.out.println("occupied");
    }
    if (SecondTest.CheckDraw()) {
        break;
    }
}
