Nyancat

This is an easter egg to be used with the "eeaas" package.

Installation

yarn add eeaas
yarn add eeaas-nyancat

Once installed you can import the easter egg and enable it.

Usage

import Eeaas from 'eeaas';
import Nyancat from 'eeaas-nyancat';

Eeaas.register(Nyancat); // Register nyancat
Eeaas.enable(); // Enable all easter eggs, or alternatively use `Eeaas.Eggs.Nyancat.enable()` to only enable nyancat

To test if it works type "nyan" while the app is running. You should be presented with nyancat flying though the night sky following your cursor. Use the "esc" key to cancel the game.

Custom keylisteners

To use different keylisteners change the startTrigger and/or stopTrigger attributes on the Nyancat object.

import Eeaas from 'eeaas';
import Nyancat from 'eeaas-nyancat';

Nyancat.startTrigger = 'secretstring';
Nyancat.stopTrigger = ['esc', 'stop'];

Eeaas.register(Nyancat);
Eeaas.enable();

Now, typing "secretstring" will launch the game. Cancel the game by pressing the "esc" key or typing "stop".

Custom start and/or stop trigger methods

To write your own custom methods you'll have to overwrite the enable and disable attributes on the Nyancat object as well as the relevant "trigger" attributes.

Example: You want to trigger the game only when a button is clicked

Add a button to your markup:

<button id="nyancat-trigger-button">Nyancat trigger</button>

Update the enable, disable and startTrigger attributes:

import Eeaas from 'eeaas';
import Nyancat from 'eeaas-nyancat';

Object.assign(Nyancat, {
  enable() {
    this.startTrigger();
  },

  disable() {
    document.getElementById('nyancat-trigger-button').removeEventListener('click', this.start);
    this.stop();
  },

  startTrigger() {
    // The button needs to be in the DOM by the time this code runs
    document.getElementById('nyancat-trigger-button').addEventListener('click', this.start);
  }
});

Eeaas.register(Nyancat);
Eeaas.enable();
