SFS2X multi-threading demystified

Often times articles in this blog are inspired by questions and issues raised by our users and this new entry is no exception. One aspect of SmartFoxServer that seems to intimidate developers is the multi-threaded environment behind custom Extensions, and the relative implications in terms of concurrency, scalability and performance.

In this new entry we’re going to demystify the subject and demonstrate how simple and painless is writing server side code, even when many other things are running concurrently. Continue reading →

Best of both worlds: SFS2X + server side Unity for realtime games (p2)

In part one of this article series we took a bird’s eye look at various client-server strategies for action multiplayer games. We then highlighted the advantages of running an hybrid solution with SmartFoxServer 2X and Unity on the server side to combine the best of both worlds.

In this second part we’ll be looking at the details of implementing such a solution, the potential difficulties and how to overcome them.

If you have skipped the first article we highly recommend to go back and read it, before you proceed. Continue reading →

Functional Java in server side Extensions

With the release of patch 2.13.1 SmartFoxServer 2X adds support for functional Java and lambdas in server side Extensions. In this article we’re going to take a closer look at how we can use lambdas in our server side code. Continue reading →

Better ways of logging Exceptions in SFS2X

A recent discussion on our support forum brought up the struggle of sending enough details to the log files when an Exception is caught on the server side. In this article we provide a few options to improve error reporting in your Extensions and avoid those puzzling, single-line errors. Continue reading →

JavaScript is back!

With the release of SFS2X 2.13 last week we’re happy to reintroduce JavaScript as a server side language. For those familiar with the history of SmartFoxServer, JavaScript has been available since the early days of SFS PRO for writing server side code, and it’s now coming back thanks to the latest improvements in JDK 7 and 8.

SmartFoxServer 2X 2.13 released!

A new SmartFoxServer 2X version is available that focuses mainly on JavaScript for both client and server side.

We’re gladly re-introducing JavaScript as full-fledged server-side language for Extensions, thanks to the improved performance of the Nashorn engine, provided in JDK 8. Continue reading →

The return of JavaScript

As disclosed in our latest newsletter, JavaScript is coming back to SmartFoxServer!

With release 2.13 we’ll launch a new JavaScript client API taking full advantage of the SmartFoxServer 2X binary (and compressed) protocol, providing improved network efficiency. Continue reading →

Using properties files to load Extension settings

Often times server-side code requires a number of configuration parameters that can be easily tweaked without recompiling and re-deploying the Extension. In this article we will show a useful and little known feature of SFS2X’s Extensions. Continue reading →

Custom logging for SFS2X Extensions

In this recipe we will take a look at how we can tweak the logging configuration in SmartFoxServer 2X in order to do advanced logging from Extension code. Continue reading →

HTTP Request and Extensions integration

In this new recipe we’re going to take a look at how we can integrate regular HTTP calls with the SmartFoxServer runtime and specifically how to communicate with Extension code via HTTP GET/POST requests.

Common applications of the HTTP/Extension interoperability are debugging interfaces and administration UIs. With this approach developers can easily build a simple web interface that reports that game state, monitors data structures, users etc… allowing to quickly debug problems while testing, triggering events and so on.
