Installation

npm i nylira-maze --save

Usage

Basic usage:

var maze = require('nylira-maze')

// returns a 2d array of values for a 10x10 maze
maze()

// returns a 2d array of values for a 20x20 maze
maze(20)

// returns a 2d array of values for a 15x23 maze
maze(15, 23)

Parameters

maze(31, 23, 'growing-tree:newest', 0.65, undefined, true)

• Parameter 1: Width.
• Parameter 2: Height.
• Parameter 3: The maze generation algorithm. Options:
  • "growing-tree": The Growing Tree algorithm. Defaults to random.
  • "growing-tree:random": Lots of dead ends, similar to Prim's Algorithm
  • "growing-tree:newest": Long windy passages, similar to "backtracker"
  • "growing-tree:middle": Lots of long straight passages.
  • "growing-tree:oldest": Only long straight passages.
  • "backtracker": The Recursive Backtracker algorithm. Tends towards long and twisted passages.
• Parameter 4: Sparseness. A sparse maze will have some of its nodes removed. If you type in a value less than 1, e.g. 0.25, the maze will be 25% sparse. If you enter an integer value more than 1, e.g. 5, the maze will remove 5 nodes from each of its dead ends.
• Parameter 5: The integer seed for the maze. Putting a value here will guaranteee you can recreate the maze over and over again.
• Parameter 6: You can preview the grid by passing in true as the fifth parameter.

That function call above will generate the following:
