snake js is a simple snake-style game written purely in javascript, for fun. It's not intended to be perfectly cross-browser compatible, though reasonable attempt will be made to do so. This is mostly a personal project to get my head around working with javascript more.
For ease of development and testing, I've bundled it with a gemfile containing jekyll so people can get it running in a browser quickly.
Make sure you have a working version of Ruby installed, with the Bundler gem.
Clone snakejs and navigate to the folder:
git clone https://github.com/bluefantail/snakejs.git
cd snakejs
Install dependencies (Jekyll) using bundler:
$ bundle install
After Jekyll is installed run:
$ jekyll serve
snakejs should be available at http://localhost:4000
A few things can be changed to modify snakejs
Config at the top of snake.scss contains variables to modify sizes and colours.
Use $tile-size to set the size of a tile.
$game-width and $game-height will then multiply with $tile-size to produce the grid.
Eg. $tile-size: 10px; and $game-width: 50;, $game-height: 50;, will produce a 500px x 500px grid with 10px x 10px tiles.
// Game
$tile-size: 12px; // Default 12px
$game-width: 45; // Default 45
$game-height: 45; // Default 45
Colours should be fairly self explanatory.
// Colours
$blue: #0076E3;
$food: #CE0049;
$snake: green;
Set the initial snake length, and game speed with these at the top of snake.js
var startLength = 6; // Starting snake length
var gameSpeed = 60; // Set the game movement speed in milliseconds
