There are several people who have reported problems with UDP in the FPS demo that was just released.

Has anyone been having trouble with UDP in general using Unity on Windows?

on vista 64 bit i'm getting :

[SFS DEBUG] UDPSocketLayer: Error reading data from socket: An existing connection was forcibly closed by the remote host.
[SFS DEBUG] Unexpected UDP I/O Error. Error reading data from socket: An existing connection was forcibly closed by the remote host.
[ConnectionReset]
[SFS DEBUG] UDPSocketLayer: Exception aborting socket thread: Thread was being aborted
UDP error:
UnityEngine.Debug:Log(Object)
LobbyGUI:OnUdpInit(BaseEvent) (at Assets/Lobby/Scripts/LobbyGUI.cs:141)
Sfs2X.Core.EventDispatcher:DispatchEvent(BaseEvent)
Sfs2X.SmartFox:ProcessEvents()
LobbyGUI:FixedUpdate() (at Assets/Lobby/Scripts/LobbyGUI.cs:83)

From the location of the exception it seems that UDP isnt even initializing.

I take it that both the server and client are running on the windows box?

Running SFS2X rc1a?

Could you please try to connect your game client to this ip: XXXX (shut down again) (my laptop on a mac running rc1a - so just running right now)

See if we can isolate things to server, api or game code.

Thanks

I solved this UDP issue for me. Even with the Windows Firewall disabled adding an exception on port 9933 (I added both TCP and UDP but UDP only migh be enough) solved the problem for me and I was able to connect and play. Win XP Pro, but I believe it's the same for all.

I already had the ports open for SFS2X previously so I didn't have any problems there (Windows 7 native Firewall). The only additional step required here was to enable UDP in the SFS2X Admin panel (this step is also in the tutorial pdf).

The FPS demo works on my windows server. Great job and thanks Thomas!

Thomas,

i got a policy error when connecting to yours :


[SFS DEBUG] TCPSocketLayer: General exception on connection: Unable to connect, as no valid crossdomain policy was found at System.Net.Sockets.Socket.Connect_internal (IntPtr sock, System.Net.SocketAddress sa, System.Int32& error, Boolean requireSocketPolicyFile) [0x00000] in <filename unknown>:0
at System.Net.Sockets.Socket.Connect (System.Net.EndPoint remoteEP, Boolean requireSocketPolicy) [0x00000] in <filename unknown>:0

at Sfs2X.Core.Sockets.TCPSocketLayer.ConnectThread () [0x00000] in <filename unknown>:0

Ahhh - did you add the policy prefetch command to the code?

Another todo I guess for the code - can comment it out with a fat comment

/Thomas

ah... will add it.

yep, now it's working and i don't get the error anymore

Purrfect

the error ive got is, ive only just looked at the demo though, im using 10.6.5 and sf2 rca1 and using unity 2.6

did you enable UDP on the server ?

it was a nice caching error from left over logs and files from the preview version fixed now

Hey, I have a bit of problem with UDP on windows 7 x64.
Before the demo release I wrote my own multiplayer code but had problems that the game would allways freeze when I tryied to quit it with UDP enabled.
Problem were gone if I used TCP.
I thought it was just something wrong in my code but the same problem exists in the FPS demo.
So atleast I am getting freezes when trying to exit the game with UDP in use.
