Code	/*************************************** * This Program randomly generates detailed planets. * The planet is different every time you press Restart or Click The Planet * * It was created for my Space Journey Game * https://www.khanacademy.org/cs/space-journey-current-release/5922406678921216 * * Alot of people asked where the rings are. Since this is random, * sometimes the planet has rings and sometimes it does not :) * * Time and Time again I am impressed by the awesomeness of this community. * Not just because they vote for things I make, but because they are passionate * about code, about building, about knowledge, and about making something great. * Thank you - every one of you - for being a part of something so awesome :D * * star animation seems to cause some lag so * you can now set animation = false for less lag. * Thanks to @Jprogrammer for the low lag idea. * * Added a planet name generator, as per @GreenChmos suggestion. * You can disable it by setting showName = false; * * Author: Y. H. * Date: 06/01/2014 * * ***********************************/ var showName = true; // make this false if you don't want to see a name var animation = true; // make this false if you are having lag /***********************************/ var toCamelCase = function(string) { return string.charAt(0, 1).toUpperCase() + string.substring(1, string.length);
