Dedicated Server - Looking for Feedback

[victorcrimea]

Hey everyone, I've been working on a dedicated server for 0 A.D. and it's reached a point where I'd love to get some community feedback on it. The idea came from two problems that have bugged me (and probably many of you) for a while: players who can't host games and players rage-quitting rated games.

 

What it does (implemented and working):

• Game hosting - players connect to the dedicated server instead of directly to each other. No more NAT headaches. If you have ipv4, you can play.
• Lobby integration - the server connects to the lobby and games appear in the game list like any regular hosted game.
• Player rejoin - If you disconnect (crash, or intentionally), you can rejoin the game in progress. The server keeps the session alive. Rejoining with AI still not supported.
• Automatic controller assignment - the first player to connect becomes the game controller.
• Unlimited observers - no cap on how many people can watch a game in progress.
• Server-authoritative pause - In rated games, the server controls pause functionality rather than leaving it up to players. No more abuse of the pause button to stall or tilt your opponent. Every player has a total budget of 3 minutes. It used both for pause time and disconnected time.
• Rage-quit detection. When a player disconnects from a rated game without resigning, the server posts a public message in the lobby chat. It won't stop anyone from quitting, but at least there's a visible record. I hope this can be integrated with existing lobby bots.
• Auto-restart - when last client disconnects, server is pruned and started again from scratch.

 

The server supports following operating modes depending on how you want to integrate with the lobby:
- no lobby, for direct IP connection.
- single lobby account - use your own credentials to host advertise the game in the lobby. The problem is that you won't see your own game. TBD
- multiple lobby account - server can use a pool of lobby accounts. In this case it can host as many games as number of accounts provided. At the moment this is against TOS, to use multiple user accounts. so this mode is a proof of concept only.

 

Technical details for the curious
The server is written in Rust. It's a network-only relay, it coordinates packet forwarding between clients but doesn't run the game simulation itself. The actual gameplay still uses pyrogenesis's existing lockstep networking model. the server just sits in the middle instead of one player acting as host. Code is here: https://gitea.wildfiregames.com/victorcrimea/0ad/src/branch/feature/dedicated-server/server

 

What I'm looking for: I'd love to hear from real players what features are especially valuable to you? Would you use this? Any concerns about the approach, reliability, trust, anything really.

I love the idea to observe game with 8 or so players without lagging the host. At some point 8 vs 8 with 16 spactators.... Yoooooo!

"Automatic controller assignment" what does this mean? Where does this dedicated server location be? Is it per continent or is it only 1 currently? Do you collect information besides my IP and will it be encrypted? Will this have maintenence fee? How many max players can you accept? Does having too much players cause stress to server? Are you protected against DDOS? Will this follow LAN's rule of modded game(some players play modded and some vanilla)?

Features I look forward to is being able to draw in a stale[>60min]/laggy[<5min] matchup. Is all I can think of, goodluck in the further improvement and thank you for your contribution.

Please mind that we consider any player operated bots in the multiplayer lobby to be a violation of the Terms of Use.
