Question

我正在尝试重新创建Lights Out，并使用棋盘随机分配器开始游戏。当我使用boardRandomizer时，即使我的代码从一个完全关闭的位置启动该板，然后使用Math.Random随机选取灯光x次数，我仍然发现该板无法解决，< / p>

Answer 1

for (int randomCount = 0; randomCount <= 50; randomCount++) {
    randomRow = (int) (Math.random() * intBoardSize);
    randomColumn = (int) (Math.random() * intBoardSize);
    toggleLight(randomRow, randomColumn);
}

应该是

for (int randomCount = 0; randomCount <= 50; randomCount++) {
    randomRow = (int) (Math.random() * intBoardSize);
    randomColumn = (int) (Math.random() * intBoardSize);
    toggleAdjacentLights(randomRow, randomColumn);
}

否则，随机发生器执行非法移动。

您应该重构代码，以使toggleLight是Board中的私有方法，以防止将来出现此类错误。

请考虑以下内容：

import java.util.Arrays;

class Board {
    public static void main(String[] args) {
        Board board = new Board();
        boardRandomize(board);
        System.out.println(Arrays.deepToString(board.boolLightState));
    }

    public static void boardRandomize(Board board) {
        board.resetBoard();

        int randomRow, randomColumn;

        for (int randomCount = 0; randomCount <= 50; randomCount++) {
            randomRow = (int) (Math.random() * board.intBoardSize);
            randomColumn = (int) (Math.random() * board.intBoardSize);
            board.toggleAdjacentLights(randomRow, randomColumn);
        }
    }

    private final int intBoardSize = 5;
    private boolean[][] boolLightState = new boolean[intBoardSize][intBoardSize];

    public void resetBoard() {
        for (int row = 0; row < intBoardSize; row++)
            for (int column = 0; column < intBoardSize; column++)
                boolLightState[row][column] = false;
    }

    public void toggleAdjacentLights(int row, int column) {

        toggleLight(row, column);

        if (row + 1 >= 0 && row + 1 < intBoardSize)
            toggleLight(row + 1, column);

        if (row - 1 >= 0 && row - 1 < intBoardSize)
            toggleLight(row - 1, column);

        if (column + 1 >= 0 && column + 1 < intBoardSize)
            toggleLight(row, column + 1);

        if (column - 1 >= 0 && column - 1 < intBoardSize)
            toggleLight(row, column - 1);

    }

    //make private to prevent access
    private void toggleLight(int row, int column) {
        if (boolLightState[row][column] == false)
            boolLightState[row][column] = true;
        else
            boolLightState[row][column] = false;
        // all of the above can be simplified to
        // boolLightState[row][column] = !boolLightState[row][column];
        repaint();
    }
}
