Node module to add minesweeper to any discord bot
//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
let grid = new Array(Y);
for (let y = 0; y < Y; ++y) {
grid[y] = new Array(X);
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) {}
grid[y][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]++;
}
}
