Question

我目前只停留在一个简单的程序上，该程序有一个猜测和重置按钮，用于猜测1-100的数字。用户获得5回合。我目前的问题是我无法正确运行重置按钮。按下它时，不是完全生成新游戏，而是仅生成一个新数字，但是当按下猜测时，再次使用生成的原始数字。

我会在其中包含一些代码片段，我觉得自己犯了很大的逻辑错误。

所以只需我的计数器和初始随机数变量，然后是猜测和重置按钮

query = '''
UPDATE Exercises
SET Exercise = ?, Weight = ?
WHERE ID = ?
'''

cur.execute(query, (exercise, weight, id_))

我的随机数生成器。

       int counter = 0;
       int num = genRan();

   /////////////////////////////////////
        guessButton.setOnAction(e -> {

        int numToGuess = num;

        gameSetUp(guessField, counter, numToGuess);

    });

    //////////////////////////////////////////////////////////

    resetButton.setOnAction(e -> {

        System.out.println("Generating new game...");

        int newNum = genRan();
        int newCounter = 0;

        gameSetUp(guessField, newCounter, newNum);

    });

我认为这一切都出了问题......

public int genRan() {
        Random rand = new Random();

        int numToGuess = rand.nextInt(100) + 1;

        System.out.println("number is" + numToGuess);

        return numToGuess;
    }

感谢任何帮助，谢谢。

以下是一个示例应用，Initial State和Game Play State分开。

        guessField.setPromptText("Press New Game Button!");

        Button btnNewGame = new Button("New Game");
