Making Multiplayer Online Games

A Game Development Workbook for any JavaScript Gaming Framework.

About the Book

This book includes game design and implementation chapters using either Code-less Gaming Frameworks AND other JS Gaming Frameworks for front- and back-end development. It is a Book of 5 Rings Game Design - "HTML5, CSS, JavaScript, PHP, and SQL". It further analyzes several freely available back-end servers and supporting middleware (such as PHP, Python, and several CMS). This game design workbook takes you step-by-step into the creation of a Massively Multiplayer Online Game as a profitable business adventure - none of this theoretical, local workstation proof of concept! It uses any popular JavaScript Gaming Framework -- not just limited to Phaser.JS!! -- on the client-side browser interfacing into a unique, server-side, application using WebSockets. It is the only book of its kind since January 2017 for Phaser MMO Gaming Framework!

  • Part I leads you through the world of networks, business consideration, MMoG analysis, and setting up your studio workshop. I have 40 years of networking career experience in highly sensitive (i.e., Government Embassies) data communications. I am a certified Cisco Academy Instructor and have taught networking, networking security, game design/development, and software engineering for the past 14 years at the college level.  
  • Part II Guides you into Multi-player Online Game architecture contrasted to normal single-player games. This lays the foundation for Multi-Player Game Prototypes and reviews a missing aspect in current MMoG development not seen in many online tutorials and example code. 
  • Part III contains 3 chapters focused on production and development for the client-side code, client-proxy, server-side code, and MMoG app. This content sets the foundation for what many Phaser tutorials and Phaser Starter-Kits on the market today overlook and never tell you! Upon completion of Part III, you will have your own bespoke MMoG with integrated micro-service, and if you choose, web workers and block-chain.
  • Part IV (Bonus Content) This section includes proprietary Game Rule Books and EULA source code as part of your book purchase. It features four (4) Game Recipes -- step-by-step instructions -- listed by complexity "1" = easiest (elementary skills) to "4" = most complex (requiring advanced skills across several IT technology disciplines). Each external “Walk-Through Tutorial” guides you in different aspects of MMoG development. 
  1. How to migrate single-player games into a 2-player online delivery mode (not using "hot-seat")! 
  2. How to use dynamic client-side proxy servers and migrate this game from its current single-player mode (with AI Bot) into an online 2-player mode (not using "hot-seat")!
  3. How to include "Asynchronous Availability" during gameplay and migrate this gameplay mode (with AI Bot) into an online "Asynchronous Availability" 3-player mode using postal mail or email game turns! The FREE game rule book will help "deconstruct" this game's mechanics.
  4. This final external "Step-by-Step" tutorial guides us in building a complete MMoG CMS, using MOM over WebSockets for 2 to 8 participants, a membership system, a game lobby, player matching services, and other various cloud-based "Back-end as a Service" (BaaS). The FREE game rule book will help "deconstruct" this game's mechanics.

Reader Testimonials

B.S. Computer Science & Electrical and Electronics Engineering, University of Maryland (Verified Purchase & read)

The author knows his stuff about networking technologies. So this book presents a wealth of info on how to connect game clients and servers over networks. It's a bit too deep for some readers! But for the more practically minded, it advocates recent technologies and provides a lot of links to toolkits, libraries, and other tutorials. Many gaming how-to books give the impression that the author wants to make a quick buck, but this book feels like the author genuinely wants to make us smarter.
