//Example Usage: | |
/* | |
const mines = require('./mines.js'); | |
let msg = mines(14,14,20,'X',true); | |
*/ | |
//X - Width | |
//Y - Height | |
//char - Character to represent bombs | |
// (used internally and if formatted == false, externally to represent the bombs) | |
//formatted - Toggles what to output: | |
// formatted == True : Output string formatted with linebreaks and emojis | |
// formatted == False : Output the raw 2D Array | |
let app = function (X, Y, mines, char, formatted) { | |
//Create blank map | |

for (let x = 0; x < X; ++x) { | |
grid[y][x] = 0; | |
} | |
} | |
//Spawn mines | |
for (let i = 0; i < mines; ++i) { | |
let x,y; | |
while (grid[y = Math.floor(Math.random()*Y)][x = Math.floor(Math.random()*X)] == char) {} | |

//Increment counter on surrounding squares | |
for (let yr = y-1; yr <= y + 1; ++yr) { | |
for (let xr = x-1; xr <= x + 1; ++xr) { | |
if (xr >= 0 && xr < X && yr >= 0 && yr < Y && grid[yr][xr] >= 0) grid[yr][xr]++; | |
} | |
} | |
