spaceraces example UDP not workin on latest SFS2 api

[levancho]

game itself works but,it seems that UDP protocol is not working
I have compiled both client and server code with latest API jar/swf

I am still getting following error in console:

Code: Select all

Make sure that you configured SFS to listen for UDP packets. Launch the AdminTool > Server Configurator.
Mine looks like this:

I am also having this problem after doing an install of the latest release. I have added both TCP and UDP socket addresses for localhost, my wireless card, and my vpn link just to make sure everything is covered, and I still can't send UDP packets.

Do you have any other suggestions?

[Lapo]

You should explain which errors do you get. Check your logs on the server side. If UDP has failed you will find errors in there.

[HumanPoweredGames]

I get the same error as listed above.

From my server log:

[HumanPoweredGames]

I can provide config files if needed. This is kind of a showstopper.

[HumanPoweredGames]

Could I perhaps pay someone to help me with this issue?

Here's the relevant bit from my server.xml:


<serverSettings>
<socketAddresses>
<socket address="127.0.0.1" port="9933" type="TCP"/>
<socket address="127.0.0.1" port="9933" type="UDP"/>
<socket address="192.168.1.4" port="9933" type="UDP"/>
<socket address="192.168.137.20" port="9933" type="UDP"/>
<socket address="192.168.137.20" port="9933" type="TCP"/>
<socket address="192.168.1.4" port="9933" type="TCP"/>
</socketAddresses>

The server receives UDP packets fine. The error occurs when it tries to send UDP.

[Bax]

When you start the game, it shows a login panel where the port number for UDP communication is requested. Are you sure the default value is 9933? Because we had this set to 9934 previously (on the latest examples package release this was changed to 9933, if I remember correctly).

[HumanPoweredGames]

I should clarify: I am not running spaceraces, I am getting this error in the game I am developing.

I verified that I am connecting to 9933. The server receives UDP packets from the client with no complaints, and this code works fine on the 2x beta version I was running.

[HumanPoweredGames]

Is there any other information I can provide on this? I really do need to use UDP.

[HumanPoweredGames]

I hate to be a pest, but I am planning on releasing my game fairly soon. Is this something that can be fixed?

[Bax]

We are not aware of problems. If you check the SpaceRace game you will see it works perfectly, using the UDP communication.
Same with other non-AS3 examples. So I believe you are doing something wrong, even if it is hard to spot.
Can you provide a test case showing the issue? (please don't send your entire game).

[HumanPoweredGames]

Ok, I created a small test case, and emailed it to info@smartfoxserver.com. Please let me know if you need any more info, and thanks for your help.

[Lapo]

You are not waiting for the UDP initialization to complete. In your code there's no UDP_INIT event handler.
Please check the snippet provided in the documentation under SmartFox.InitUDP() method:
http://docs2x.smartfoxserver.com/api-do ... Index.html

[HumanPoweredGames]

Thank you for looking into it... you found my problem. Sorry to bother you with that.

One other thing I discovered is that you have to call InitUDP() AFTER you log in to the zone, or the UDP_INIT callback never happens, and the session just times out.

Here's my connection code, for anyone else who might be having trouble:

            StartCoroutine(PingIt ());
         }
         else
            print ("UDP Failed");         
      });
