Often times in the server-side game logic it is necessary to use timers for recurring events that are sent to the clients (e.g. the end of a turn time, npc actions, etc).
A quick solution to this problem is using the ScheduledThreadPoolExecutor class, provided in the JDK, which offers a convenient task executor backed by a pool of threads. SFS2X already runs its own instance of this Executor (wrapped in a class called TaskScheduler). Continue reading
You can easily attach a Remote Debugger to the server and enable your favorite Debugger for bug hunting in your Extensions.
SmartFoxServer 2X can be started with the sfs2x.bat (Windows) or sfs2x.sh (Linux/Unix/MacOSX) scripts. By adding some JVM switches to the launch script you can enable remote debugging. You can do it by following these steps: Continue reading
SFS2X provides detailed logging of all its activities. You can consult them at any time by checking the logs/folder. Additionally under the logs/boot/ folder you will find detailed logs of the boot phase. Continue reading
Together with SFS2X we provide the latest version of our SmartFoxBits components, which can save you a ton of time in setting up the application GUI if you are using the Adobe Flash platform to build your client.
The base SmartFoxBits pack contains five components:
You can check all the details and read the documentation on the SmartFoxBits page.
There can be cases in which one application requires to connect to multiple databases. By default each Zone in SFS2X exposes a single DBManager object but we can create more of these via code, to manage multiple data sources. Continue reading
This recipe shows how to read data from a database and send it to the client in a convenient format. Continue reading
This recipe discusses the common scenario in which you need to validate the client credentials against the user profiles stored in a database. We will also show how to execute more custom logic right after the login, for example setting User Variables and joining a Room from server-side. Continue reading
Implementing a custom login on the server-side is a simple process. SFS2X fires the following two login events.
SFS2X allows connecting to databases in a way that is very similar to its predecessor. All you need to do is downloading the JDBC connector from your Database vendor (e.g. MySQL or MSSQL) and drop the .jar in the {SFS2XRoot}/lib/ folder.
Of course if you use ODBC instead of JDBC you can even skip the driver deployment step. In fact the ODBC driver is already provided by the Java Runtime.
The following is a list of pages where you can find the JDBC drivers for the most common RDBMS:
The next step is running the SFS2X AdminTool, launch the Zone Configurator module, select your Zone and finally click on the Database manager tab to edit the configuration.
At the end of the process click Submit and restart the server.
Adding new libraries in SmartFoxServer 2X is a breeze. No messing around with the classpath is required: all we need to do is deploy the .jar file(s) in the proper directory and restart the server.
There are two folders that we recommend to use:
{SFS2XRoot}/extensions/{the-extension-name}.
This is where we will typically deploy our main Extension .jar file. The jar file should contain only our Java code without the external dependencies, if any. The reason why the dependencies should be deployed separately is that if they are shared, they will be loaded once for all Extensions that use them.
{SFS2XRoot}/extensions/__lib__/
This folder is recommended for libraries that will be shared by multiple Extensions in your system. For example the “Google Collections” jar, or the Hibernate jar, etc. Do not add your Extension jar to this folder, because the AdminTool won’t ba able to detect it when you setup the Zone/Room configuration.
