JavaScript for Line of Business Applications

In this tutorial we will be exploring the CreateJS suite of libraries. CreateJS is suite of JavaScript libraries and tools for building rich, interactive experiences with HTML5. The CreateJS suite is divided into four libraries.

* EaselJS - Makes working with HTML5 canvas easy.
* TweenJS - For tweening HTML5 and JavaScript properties
* SoundJS - Lets you easily work with HTML5 audio
* PreloadJS - Lets you manage and coordinate loading of assets

EaselJS is a library for working with the HTML5 canvas. It consists of a full, hierarchical display list, a core interaction model, and helper classes to make working with Canvas much easier. ...

With the release of the Ouya, Xbox One and PS4 this year, couch-based console gaming appears to be as popular as ever. Despite the proliferation of multi-player games available on mobile devices, and even the advent of multi-player experiences available on the web, sitting next to the person you’re playing a game with is still an irreplaceable experience. While experimenting with Node.js and the Socket.IO library, I found a perfect opportunity to not only learn some interesting new technologies, but also experiment with using the web and common devices (computers and mobile phones) to replicate a console-like gaming experience.

This article will give a brief overview of the fundamental concepts of the Socket.IO library in the context of building a multi-player, multi-screen word game. A web browser on a large screen device, such as a TV or computer will be the ‘console’ and mobile browsers will act as the ‘controllers’. Socket.IO and Node.js will provide the necessary wiring for all the browsers to share data and provide a cohesive, real-time game experience.

During the workshop I explained exactly how to take a single player HTML5 game and turn it into a multiplayer one using Node.js and WebSockets.

Each player is identified using a unique client.id number. We'll use this later when communicating game updates to other players. For now the util.log line will output the client identification number to the terminal on connection.

The client.on event listeners are used to detect when a player has either disconnected or sent a message to the server. Right now they point to handler functions that don't exist.

It is easy to create computer game with any language. For example let’s consider JavaScript. It is a script language, it has garbage collector and it is possible to output an image with it. But the main advantage of JavaScript: it runs at any browser and you don not to use such heavy tools like MS Visual Studio to develop on it.

Let’s make a simplest roleplaying game where a hero walking through a labyrinth killing an enemy. Let the labyrinth will be 10x10 squares. Let the square will be 64px. No line of sight, no fog of war (how to implement such features I will probably tell in the one of future blog posts).
