javascript - 扫雷炸弹威胁

Question

我正在尝试用 JavaScript 构建一个扫雷游戏，但我一直坚持添加垂直炸弹威胁。

这是我的代码:

const generateBoardForPlay = function () {

  const gameBoard = [
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
  ]

  function getRandomInt(max) {
    return Math.floor(Math.random() * Math.floor(max));
  }

  const generateBombs = function () {
    return [
      [getRandomInt(9), getRandomInt(9)],
      [getRandomInt(9), getRandomInt(9)],
      [getRandomInt(9), getRandomInt(9)],
      [getRandomInt(9), getRandomInt(9)],
      [getRandomInt(9), getRandomInt(9)],
      [getRandomInt(9), getRandomInt(9)],
      [getRandomInt(9), getRandomInt(9)],
      [getRandomInt(9), getRandomInt(9)],
      [getRandomInt(9), getRandomInt(9)],
      [getRandomInt(9), getRandomInt(9)]
    ]
  }

  const bombArr = generateBombs()
  const addBombsToBoard = function (gameBoard) {
    for (let x of bombArr) {
      gameBoard[x[0]][x[1]] = "99"
    }

    return gameBoard
  }

  const board = addBombsToBoard(gameBoard)

  // return board;
  const addWarnings = function (array) {
    for (let x in array) {
      if (array[x] === '99' && x > 0 && array[x - 1] !== "99") {

        array[x - 1] += 1
      }
    }
    for (let i = array.length; i > 0; i--) {
      if (array[i] === '99' && i < 9 && array[i + 1] !== "99") {
        array[i + 1] += 1
      }
    }
    return array
  }

  addWarnings(board[0])
  addWarnings(board[1])
  addWarnings(board[2])
  addWarnings(board[3])
  addWarnings(board[4])
  addWarnings(board[5])
  addWarnings(board[6])
  addWarnings(board[7])
  addWarnings(board[8])
  addWarnings(board[9])

  const addVerticalWarning = function (board) {
    // THIS IS WHERE I'M STUCK
  }


  return board;
}

这是输出

[
  [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
  [0, 0, 0, 1, '99', '99', '99', 1, 0, 0],
  [0, 0, 1, '99', 1, 0, 0, 0, 0, 0],
  [0, 1, '99', 1, 0, 0, 0, 1, '99', 1],
  [0, 1, '99', 1, 0, 1, '99', 1, 0, 0],
  [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
  [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
  [0, 0, 1, '99', 1, 0, 0, 0, 0, 0],
  [1, '99', 1, 0, 0, 0, 0, 0, 0, 0],
  [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
]

我收到了水平炸弹威胁，但两个循环的复杂性阻止了我弄清楚水平炸弹威胁。我这样做是为了一项作业，所以我不想只是从其他地方复制并粘贴它。如果有一种方法可以完成代码，那就太棒了，如果没有，我想为我指明了正确的方向。

您的游戏板由嵌套在父数组中的 10 个并行数组组成。
这应该可以帮助您了解如何使用并行嵌套数组来访问彼此对应的值:

// Defines the gameBoard
let gameBoard = makeGameBoard();

// Loops through rows of the gameBoard
for (let rowIndex = 0; rowIndex < gameBoard.length; rowIndex++) {
  // Defines the current row and its neighbors
  let currentRow, previousRow, nextRow;
  currentRow = gameBoard[rowIndex];
  if(rowIndex > 0){ previousRow = gameBoard[rowIndex - 1]; }
  if(rowIndex < gameBoard.length - 1){ nextRow = gameBoard[rowIndex + 1]; }

  // Loops through the current row
  for(let colIndex = 0; colIndex < currentRow.length; colIndex++){

    // Logs what is in this column for this row and neighbors...
    console.log(`row ${rowIndex}, col ${colIndex}: ${gameBoard[rowIndex][colIndex]}`);

    if (previousRow){ console.log(`in square above: ${previousRow[colIndex]}`); }
    else{ console.log("no square above first row"); }
    
    if(nextRow) {console.log(`in square below: ${nextRow[colIndex]}`); }
    else{console.log("no square below last row"); }

    console.log("");
  }
}

function makeGameBoard() {
  return [
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
  ];
}
