simon-game

An API to use for building the Simon memory game.

Simon

This is library that can be used for building a Simon web app (such as the one from Free Code Camp).

It features a simple API that you can easily plug into your application.

Install

$ npm install simon-game

Include This Library into Your Project

You can include this Tic Tac Toe module into your project by using either require or the ES6 import statement.

const simonGame = require('simon-game');
import simonGame from 'simon-game';

Simon Game

Set Up

When you require 'Simon' into your project, it gives you a function, which returns an instance of the Simon game. You can include two optional parameters: first is the number of possibilities (it defaults to 4), and the length of the initial series (this defaults to 20, per the requirements of the Free Code Camp project).

Example:

// If you want to go with the default configuration
const simon = simonGame();

or:

// If you want to make a more complex game of Simon with 8 possible moves and
// and a series length of 40
const simon = simonGame(8, 40);

Using the game

The game uses numbers in its pattern series, and when you initialize a game, it automatically configures a series.

To get the full series, call the getFullSeries method.

const simon = Simon();
// get the full series up front
simon.getFullSeries()
// [1, 2, 3, 2, 3, 4, 3, 1, 1, 1, 4, 4, 2, 3, 2, 2, 1, 1, 3, 2]

You can also get a totally different series with the newSeries method:

simon.newSeries()
simon.getFullSeries()
// [3, 1, 3, 2, 1, 4, 2, 1, 4, 3, 2, 2, 3, 2, 4, 1, 1, 2, 1, 3]

Once you've initialized your simon instance, you have access to the count, using the getCount method, and the current part of the series you're on, using the getCurrent method:

simon.getFullSeries()
// [3, 1, 3, 2, 1, 4, 2, 1, 4, 3, 2, 2, 3, 2, 4, 1, 1, 2, 1, 3]
simon.getCount()
// 1
simon.getCurrent()
// [3]

You can check user input for each move in the series with the checkGuess method, which will return a boolean:

simon.getCurrent()
// [3]
simon.checkGuess(3)
// true

You can get the number of guesses made in a try by calling the getGuesses method. It can be used to check against the series count:

simon.getGuesses()
// 0
simon.getCurrent()
// [3]
simon.checkGuess(3)
// true
simon.getGuesses()
// 1

You then call the next method, which updates both the count and the current series:

simon.getCount()
// 1
simon.getCurrent()
// [3]
simon.next()
simon.getCount()
// 2
simon.getCurrent()
// [3, 1]

You can check sequential user input again:

simon.getCurrent()
// [3, 1]
simon.checkGuess(3)
// true
simon.checkGuess(1)
// true

If the guess is incorrect, checkGuess returns false and resets the check iterator, so the user can retry the pattern:

simon.getCurrent()
// [3, 1, 3]
simon.checkGuess(3)
// true
simon.checkGuess(1)
// true
simon.checkGuess(1)
// false
simon.checkGuess(3)
// true
simon.checkGuess(1)
// true
simon.checkGuess(3)
// true

With checkGuess, the user must individually guess all answers in sequence.

As a simpler alternative to the iterative checkGuess method, you can check an entire series of guesses at once with the checkSeries method:

simon.getCurrent()
// [3, 1, 3, 2]
simon.checkSeries([3, 1, 3, 2])
// true

And that's it! You can decide when the user has won or lost. My goal was to create a simple library that holds the logic and state of a simple Simon app. You won't need to do any resets on state because as long as you are moving the game along and giving valid inputs, the main Simon module will keep track of the state for you.
