[Configure my own multiplayer lobby]

Hi, thanks again for your help.

Now I can do hosting & joining games, and chat with other players.

But, there are still not working issue.

Leaderboard and profile lookup don't work for now.

I found that rating bot uses sql database, unlike you said before.

According to the installation guide, I have created new sql db file called lobby_rankings.sqlite3 by running command python3 lobby_ranking.py create.

But when I run the echelon.py, bunch of sql db errors appear.

For example, when I search player on proflie lookup, then following error is shown.

KeyError: 'rating'
2022-08-19 14:20:07 ERROR    Failed to send profile about  to

Could you please explain how to fix this?

[Configure my own multiplayer lobby]

Hi @Dunedanthanks for your help! Now I can connect with my account into multiplayer lobby, but I have one more problem.

When Im going to host new game, it fails with the error dialog saying "Cannot host game.. Failed to host via STUN".

But when I disable the checkbox "Use STUN to work around firewalls", it works.

So i guess the reason is because of STUN configuration in ejabberd, but I'm not sure which one needs to be modified.

This is STUN related setting in ejabberd config file.

port: 3478

ip: "0.0.0.0

transport: udp

module: ejabberd_stun

use_turn: true

turn_ipv4_address: "x.x.x.x

Thanks for your advices.

In existing 0 A.D game's multiplayer lobby, it sends response after the player connected to lobby.

{"time": 166032701, "historic": false "level": "connected", "type": "system"}

{"time": 166032702, "historic": false "level": "subject", "type": "chat", "nick": "user1", "subject": "This is the svn multiplayer lobby,\n\n If you want to play..."}

{"time": 166032702, "historic": false "level": "gamelist", "type": "game"}

I just tried to print response messages when new ones arrived from lobby server.

Above statements are arrived when the game uses current 0A.D's multiplayer lobby.

But after I have replaced it with my own server, nothing arrives.

Also I'm wondering about who sends this message to the game client.

Because I can't find any string resource like "This is the svn multiplayer lobby,\n\n If you want to play..." anywhere. There aren't any such string in source code of the game and multiplayer lobby.

At that point the bots play no role yet, so you can ignore everything related to the bots

So this means that hosting/joining game is impossible even after all is configured well?

To help you further we'd need some more information, like the 0ad configuration options you used, screenshots of the problem and a debug log from ejabberd.

Thanks, let me share my configuration information.
First, following is my default.cfg lobby settings

xpartamupp = "xpartamupp"             ; Name of the server-side XMPP-account that manage games

echelon = "echelon"               ; Name of the server-side XMPP-account that manages ratings

buddies = ","                       ; Comma separated list of playernames that the current user has marked as buddies

rememberpassword = true             ; Whether to store the encrypted password in the user config

 

[lobby.columns]

gamerating = false                  ; Show the average rating of the participating players in a column of the gamelist

 

[lobby.stun]

enabled = true                       ; The STUN protocol allows hosting games without configuring the firewall and router.

                                     ; If STUN is disabled, the game relies on direct connection, UPnP and port forwarding.

server = "ec2-54-174-96-13.compute-1.amazonaws.com"   ; Address of the STUN server.

port = 3478                          ; Port of the STUN server.

delay = 200                          ; Duration in milliseconds that is waited between STUN messages.

                                     ; Smaller numbers speed up joins but also become less stable.

I have configured ejabberd on aws ec2 instance.

As I said, I can register new account in game and after I try to connect, the game keep says "connecting...", but ejabbered log and web admin says the account is connected and online. 

This is ejabberd log statements, I disabled TLS in authetication.
2022-08-13 16:30:06.144478+00:00 [info] <0.777.0>@ejabberd_listener:accept/7:273 (<0.4170.0>) Accepted connection 188.43.235.177:17278 -> 172.31.28.90:5222

Above is what ejabberd admin page shows in users panel.

By using other XMPP client like Pidgin, I can create account and login, chat there.

But as the game uses encrypted password by itself, so I can't use the account create by game in other xmpp client as password is regarded incorrect.

 

[Configure my own multiplayer lobby]

Hi, thanks for your reply.

But I don't think this is because of UI. Its due to multiplayer lobby configuration I think.

If you have completed guide to configure multiplayer lobby, please let me take a look at it.

As I wrote above, something is missing so far, I can't go forward anymore.

[Configure my own multiplayer lobby]

Hi, hope you are doing well.

I've been trying to configure multiplayer lobby on my server, but I have some problems.

According to the guide of installation of lobby bots here, I've configured ejabberd 22.05(latest) and executed xpartamupp.py and echelon.py scripts.

And I've replaced original lobby options such as room name, lobby url, etc  according to new lobby server.

At this point, I have following problems.

- I can register new account to multiplayer lobby, so I can confirm this in ejabberd admin page also. But I can't login with created account in the game.

Login dialog keeps saying "connecting..." after the connection is established. Why I think like this is because the account which I used is displayed as online status in ejabberd web admin, but not in the game. In ejabberd log, it also says new connection is opened.

- Server returns nothing response.

In existing 0 A.D game's multiplayer lobby, it sends response after the player connected to lobby.

{"time": 166032701, "historic": false "level": "connected", "type": "system"}

{"time": 166032702, "historic": false "level": "subject", "type": "chat", "nick": "user1", "subject": "This is the svn multiplayer lobby,\n\n If you want to play..."}

{"time": 166032702, "historic": false "level": "gamelist", "type": "game"}

But my server doesn't. It only sens response when the username and password are incorrect or unregister account is used.

 

I guess there is one more component to be installed for proper work of multiplayer lobby on my side.

There isn't any postgresql db handler on my model and both source code of game and multiplayer lobby-bots don't contain any one of above strings.

Also, the weird thing is that github repo name is just "lobby-bots", not "lobby", which means entire name of system

Please let me know how to fix this issue.

Thanks in advance for your help!
