Hi, it would help to see an example of a message that doesn't go through. If you can identify one it would also help to try and reproduce the issue. In any case here are a couple of thoughts: 1- unless you're sending data via UDP (which requires a specific flag in the send() method) all packets are ...

Hi,
it depends on what level of security you want to achieve.
The basic level is to at least use SSL on the Lobby server to protect chat and user data. On Game cluster nodes it may be needed or not depending on what kind of data is transmitted.

Cheers

1. " if you need SSL the certificates": means that SFS2x works without SSL and the data is still safe? To protect the communication you will need to deploy an SSL certificate, as usual with every server. What is different is how the encryption is implemented compared to a regular web stac...

Hi, I don't think this setup would work. SmartFoxServer doesn't work like a regular web-server because it's based on a custom protocol on top of TCP and UDP. You can use a layer-4 load balancer but if you need SSL the certificates must be deployed on the SFS2X instances rather than the load balancer...

If you need direct interaction between Room and Zone Extensions and the Zone Extension is already deployed in the top class loader (__lib__), I would just suggest to also deploy the Room Extension there.

Hi, connections to the database are normally run in a local network so disconnections are highly unlikely. If you get disconnected in the middle of a DB transaction you will get a SQLException. Is it any problem if I run multiple functions in a row with dbManager like this? No it's not a problem. Is...

Hi, there isn't an equivalent option in SFS2X as the original feature in SFS PRO was rarely (if ever) used. In theory making the server intolerant to packet drops would result in a worse user experience, since players with a slow/bad connection would also start disconnecting more often. Generally sp...

Hi, a millisecond resolution for the uptime doesn't make sense. I was thinking to just use System.currentTimeMillis(); which returns a long milliseconds, depending on system time. Yes that's correct. It uses System Time, and SFS doesnt have built in server time? No, you can obtain the server time di...

The ChatGPT example makes no sense :shock: :D Interop with Extension can be tricky because they are segregated in different class loaders. To avoid class loader headaches we have introduce the simple "message" system where you invoke the handleInternalMessage() method. I would just recomme...

Hi,
no sorry there isn't a mechanism to invoke Extension prior to having logged in. It would open a whole pandora's box of security exploits and attacks.
The only allowed interaction is the login request.

Cheers

I would start by checking the logs and looking for exceptions. If the postProcess class is not invoked I'd expect some error to prevent it from running.

Cheers

May I ask why it doesn't work for deployment? We tried that, but sadly it is not good for deployment, are there any plans to upgrade the jackson jar files from your side? Not at the moment. We have plans to transition to Java 21 LTS at some point and we'll likely have to update a number of dependenc...

Hi, I am not familiar with either of those sdks. It is possible that there's a jar conflict and you should be able to ascertain it by checking which version are the "colliding" jar files. If either of those sdks contain more recent versions of the jackson parser then I'd suggest to try and...

Hi,
from your snippets it looks like you're handling the USER_DISCONNECT event.
The event passes a bunch of parameters, one is the User itself, from which you can obtain the name:


I am not sure what's the need for the workaround you have described.

Cheers

Everytime I reload an extension the terminal traces my extension starting up and then immediately after traces the destroy() function being called. The destroy() invocation you see is not from the new Extension that was just started, but rather from the old instance , which is getting unloaded. Sma...
