Hi, no, we don't support GraalVM. I also doubt it would offer any significant improvements. JIT compilation is typically better than AOT (especially in our case) since the former is dynamic (i.e. adapts to runtime conditions) whereas AOT is static. Not to say that GraalVM doesn't have its benefits,...

Very rarely the error "Can't remove user" occurs. SmartFoxServer 2.19.0 Code: for (Room joinedRoom : user.getJoinedRooms()) { if (joinedRoom.containsUser(user)) { API.leaveRoom(user, joinedRoom); } } Stack Trace: com.smartfoxserver.v2.exceptions.SFSRuntimeException: Can't remove user: ( Us...

Hi, I am not sure what you mean by "too manu logout requests". The error reported is triggered by a Login request that arrives at the server when the session is no longer open. Keep in mind that default Session idle time is only 20 seconds, so if your use case requires longer pauses betwe...

After too many LogoutRequests "[SFSWorker:Ext:3] api.SFSApi - Login failed: username, session is already expired!" starts to happen.

You can set up a LoginRequest -> LogoutRequest loop to replicate.

I caught 3 exceptions from server in production.
I don't know if these have any effect on behavior.

Hi, if the network is disabled by pulling the ethernet cable or shutting down wifi then yes, that's expected. It's not something special in SFS2X, it's how TCP/IP works. The disconnection will happen but at a later time when the TCP timeout is triggered. To understand better please read this: https...

If the network connection is disconnected, SmartFox Server does not know if the user is disconnected or not.
In my tests, if the network connection is lost, the user is never disconnected!

It is so sad. Unity breaks many developer's heart and destroys many of development. In my case, one of the development used Unity but I considered to move the project to unreal. Godot have tons of issues cannot be solved in short time. I am not going to Godot. --- Latest version of unreal: Unreal 5...

I want to get the number of online players on the Zone, but how can I do this without including NPCs?

removeRoom destroys the extension but if we call more than one removeRoom, more than one destroy works like this. SmartFoxServer.getInstance().getAPIManager().getSFSApi().removeRoom(room); //Calls destory on extension SmartFoxServer.getInstance().getAPIManager().getSFSApi().removeRoom(room); //Call...

Just to confirm, X-Forwarded-For works with CloudFlare to get the original IP just fine, it also works with HAProxy. As an aside, CloudFlare's WebSockets are unreliable in my opinion. I would suggest not using them. Cloudflare's websockets are not unreliable, they just have their own standards. *Si...

Just to confirm, X-Forwarded-For works with CloudFlare to get the original IP just fine, it also works with HAProxy. As an aside, CloudFlare's WebSockets are unreliable in my opinion. I would suggest not using them. By sending X-Forwarded-For, the user can change the IP address to custom, but if yo...

I am sorry but I don't get it. :( The "X-Forwarded-For" field gives you the original IP of the client, instead of the address if the proxy connecting to your SFS instance. Isn't this what we're talking about? It's not clear to me what this custom property (CF-Connecting-Ip) does that it i...

Hi, can you clarify what difference does it make? Given that the "X-Forwarded-For" field provides the original IP address of the client, what is the advantage of using the custom header field? Thanks "X-Forwarded-For" is used by proxies to send real ips. This header value needs ...
