Game State

The Minesweeper game is internally represented by a 2D array of integers. See below for the range of integer values and their meanings.

Cell State Legend:

• 0: Unvisited, no bomb

• 1: Unvisited, bomb

• 2: Visited, no bomb

• 3: Unvisited, no bomb, flagged

• 4: Unvisited, bomb, flagged

A client to this API interacts with the internal board state via the public game grid, a 2D array of strings representing what the player sees when they play the game.

API

Public Methods:

• checkCell - Select a cell to sweep for a bomb.
• flagCell - Flag a cell as possibly having a bomb.
• cellIsFlagged - Check if a cell is flagged.
• getNumRows - Returns height of underlying matrix i.e. number of rows.
• getNumColumns - Returns width of underlying matrix i.e. number of columns.
• getNumBombs - Returns number of bombs in matrix.
• getStatus - Returns game status e.g. won, lost, or in-progress.
• getGrid - Returns a 2D array of strings representing what the player sees when they play the game.

Usage

// require statement
const MinesweeperGame = require('minesweeper-ultimate');

// import statement
import MinesweeperGame from 'minesweeper-ultimate';

const game = new MinesweeperGame(/* difficulty */, /* options */);

Difficulty setting is required. If difficulty set to 'custom', options are required, otherwise they are unused.

Difficulty Settings:

• 'easy'
• 'medium'
• 'hard'
• 'custom'

Options Interface:

{
  n: /* number of rows */,
  m: /* number of columns */,
  b: /* number of bombs */
}

game.checkCell(/* row */, /* column */); /* --> void */

/*
Checks a cell for a bomb. If cell does not have a bomb, counts surrounding bombs. If surrounding bomb count is zero, sweeps grid until it has found cells with a bomb count. Returns void i.e. implicit return of undefined.
*/

game.flagCell(/* row */, /* column */); /* --> void */

/*
Updates board state to indicate cell is flagged. Can only flag unvisited cells. Returns void i.e. implicit return of undefined.
*/

game.cellIsFlagged(/* row */, /* column */); /* --> boolean */

/*
Returns true if cell is flagged and false if not.
*/

game.getNumRows(); /* --> integer */

/*
Returns height of underlying matrix i.e. number of rows.
*/

game.getNumColumns(); /* --> integer */

/*
Returns width of underlying matrix i.e. number of columns.
*/

game.getNumBombs(); /* --> integer */

/*
Returns number of bombs in matrix.
*/

game.getStatus(); /* --> string */

/*
Returns game status as a string e.g. won, lost, or in-progress.
*/

game.getGrid(); /* --> [][]string */

/*
Returns a 2D array of strings representing what the player sees when they play the game.
