Creating a chat in Flash is easy using ElectroServer and MXML. If you are interested in creating multiplayer games, then first creating a simple chat application can help you learn the basic API calls used to communicate with ElectroServer. After building something like this you will have enough confidence to take the next step toward making a multilayer game!

At a high level you do the following to create a chat,

  • Download and install ElectroServer to get it running on your machine.
  • Create a new Flash project that uses the Flex Framework so that you can easily add UI components.
  • Add a few dozen lines of code to hook the ElectroServer API up to the UI.

This tutorial shows you how to create a chat step-by-step.

After many months of hard work by the team at Electrotank, I’m pleased to say that ElectroServer 5 (ES5) is out the door and ready to power tons of new multiplayer games and MMOs! It is available now for download and comes with a free 25 concurrent user license (with no other restrictions). In addition to the great new features with the 5.0 release, we have a ton of additional features that we’ll be adding and releasing over time.

Press release

Here are some of the most notable new features.

Cross platform APIs

Over ElectroServer’s 8+ year life it has primarily been used for Flash applications. We’ve now introduced APIs across several languages keeping them as similar as possible. You can now have players play against each other across a multitude of platforms. The supported languages and platforms are,

  • AS2 and AS3 – Flash, AIR
  • C# – Unity3D, .Net, and XNA
  • Objective-C – iOS
  • Java – for any Java enabled client


For the fastest and most light weight message transfer, ElectroServer 5 provides the option for UDP messaging. UDP is needed for first-person shooters and racing games.

Message Encryption

ES5 supports strong packet encryption using the industry’s highest standard AES-128 method.

Message encryption is just one extremely effective means in which ES5 secures client-server communications. ES5 also supports cryptographically hashing passwords used to log onto the system.

Full-featured Sleek Admin

ElectroServer’s admin tool has been completely revamped to be more user-friendly (and attractive!). With it you can configure every aspect of the server. In addition, there are new reporting features built right in. You can view and configure graphs showing up-time, bandwidth usage, CPU usage, and more. There is also the ability to browse snapshots of the server to inspect which rooms exists and who is in them.

Extensive Documentation & Tons of Examples

We invested a lot of time in creating thorough documentation for every server feature. There are tutorials and more than 30 examples! ES5 also comes with a handful of complete multiplayer games.

I hope to post more on ES5 and multiplayer game development in the near future.

I recently finished writing ActionScript for Multiplayer Games and Virtual Worlds, my first book since Flash 8! With the help of some amazing contributors I think this is the most useful and geeky-fun book I’ve ever been a part of. According to Amazon (shameless link) it hits shelves in 8/3/2009.

So what’s it about? If the title of the book doesn’t give it away, it is a book that focuses on multiplayer concepts and applies them to games and virtual worlds via ActionScript. Some of the coolest topics are those on dead reckoning, real-time movement and time synchronization, loads of information on avatar rendering, and other useful topics like thorough coverage of isometric concepts.
While there are many examples throughout the book, there are 3 major examples. In one chapter we build a real-time multiplayer tank game (top down). In another chapter a cooperative multiplayer games is created, and its a fun one! Then over the course of several chapters we dig into various major topics on virtual worlds to build a complete world.
Here are some screenshots, and I hope some of you check it out and find it useful 🙂

I just got back from a fun week in Brighton, England for the Flash on the Beach conference. The weather was actually pretty amazing this year. Mostly Sunny, upper 50s, no rain! (After the blustery 2006 conference anything would be an improvement.) And as for the beer, I sampled bitters from no fewer than a dozen pubs with cool names 🙂 The Cricketer, Druid’s Head, etc

Anyway, on to the Flash stuff…

Electrotank was a FOTB sponsor and had an on-site presence. Thanks to the FOTB crowd for huge level of interest in ES4! It is always great to hear what multiplayer applications everyone is working on. Virtual worlds are all the rage right now and so we’re getting a lot of great feedback for ElectroServer’s insane scalability!

We just wrapped up another crazy week on the road. This week we attended the Flashforward conference in Boston to catch some amazing sessions and to present ElectroServer 4, our Flash streaming media and MMO server. Thanks to the attendees for the tremendous interest. It is always great to hear what innovative applications everyone is working on!

Below you can see our booth in the exhibitor area (cell pic).

We just got back from Austin Game Developer’s Conference (AGDC). What an amazing gathering of the top game developers and technology providers. Our own Mike Grundvig co-presented with Michael Bayne on web game technologies. And we had a booth to showcase ElectroServer 4. We demonstrated real-time game play and the new streaming audio/video features.

Check out our press release that went out this week.

The release of ElectroServer 4 is nearly here! We’ve been working so hard on this thing for nearly a year and a half and can’t wait to finally release it. 🙂

More than a year ago we started working on version 4 of our socket-server product called ElectroServer. To truly evolve ElectroServer we went back to the drawing board and spared no expense to do everything right.

I am proud to say that ElectroServer 4 has been load tested to 200,000 simultaneous users! And it supports streaming Video & Audio! ElectroServer is used by one of the largest MMOGs online, Webkinz World. It is also used to power games for VH1, Comedy Central, and Mattel.

Today we made our first official public announcement of ElectroServer 4 on the site. Check out our streaming demo (Night of the Living Dead) and real-time tank battle demo on our site.

I’ll be blogging countless entries on multiplayer programming techniques. It has been hard to *not* post on multiplayer concepts up till now. Consider the flood gates open…well, a little open. They’ll finish opening upon our release in September.
