conway-engine

A moderately performant engine for Conway's Game of Life

Installation

npm:

npm install conway-engine

Usage

conway-engine can be used both on node and on the browser. In the browser, loading it from a script tag will add it to the global scoped under the name of ConwayEngine

const ConwayEngine = require('conway-engine')
const conwaysGame = new ConwayEngine()

conwaysGame.tick()
console.log(conwaysGame)

Examples

API

constructor([options])

options

options.width

Number of columns the world will have

options.height

Number of rows the world will have

options.initialWorld

Describes how the world should look like at generation 0. Can be an array or a function.

If it's an array, it must be an array with height children, which must be arrays with width children, being those a boolean determining whether the cell is alive

If it's a function, it must return a boolean determining whether the cell is alive. The first argument will be the y coordinate, and the second one the x coordinate

options.seed

If no initialWorld is provided, the engine will use a pseudorandom number generator to create the initial world, with a 20% chance of a cell being alive. The seed can be a string or a number

options.rulestring

The rulestring will be used to determine how the cells are born and die. It uses B/S notation. Check http://www.conwaylife.com/wiki/Rulestring to learn more

options.enableLastTickInfo

When enabled, cells will have a aliveLastTick property which is useful to avoid unnecessary redraws, but it reduces performance when advancing generations

options.wrapOnEdges

When enabled, the edges of the world will be treated as if they were adjactent to the other side

tick()

Advances to next generation
