Generate procedural dungeons

How to use:

The example code below will generate a dungeon with default options and output a visualisation like the one from the "Examples" section:

  var Dungeon = require('./dungeon');
  var level = new Dungeon(40, 20);

  // Display the level:
  level.grid.forEach(function(g) {
    console.log(g.map(function(t) {
      return t ? '*' : ' ';
    }).join(''));
  });

You can also use the library in the browser, using browserify.

Configuration

There's a few configuration options:

Name Description Optional Default
initialProbability Probability of a tile being a wall in the initial (random) placing phase y 0.5 (50%)
iterations Iterations of the cellular automaton running on the map y 5
aliveThreshold For every cell, if there's at least aliveThreshold walls around it, it becomes a wall y 5
