Synergy News

I find city builders to be quite a stressful genre, mostly because I get freaked out as soon as my virtual bank account starts dipping into the red. Every now and then, though, one comes along that looks like it might actually be a calming time, and Synergy looks like it could fill that gap. It's been out in early access for almost a year now, but developer Leikir Studio announced today that Synergy will be leaving early access and entering 1.0 in just two weeks time on April 16th.

[h2]Steam Networking: Phase II[/h2]
[h3]Game Client[/h3]
The Synergy game client will now connect to all internet servers using the Steam Datagram Relay (SDR) by default.

This will:

• Keep your IP address hidden from servers you connect to.
  
• Encrypt all server network traffic (incoming and outgoing).
  
• Possibly lower ping times.
  

Connecting to a server via a LAN IP address will remain unchanged. It will always connect via local IP directly and bypass the SDR as it would otherwise increase ping times by going over the internet instead of staying within the LAN. However, connecting to a server on the LAN via a SteamID (e.g. connect ) will use the SDR.

If you wish to instead connect to servers with your IP address (how it worked before) then disable this ConVar:

cl_sdr_prefer 0

cl_sdr_prefer 0 will not work when trying to connect to a Dedicated Server using an anonymized IP address (see below) or when connecting via a SteamID; the SDR will still be used in those cases.

[h3]Dedicated Servers[/h3]
Synergy Dedicated Servers will now use anonymized IP addresses by default.

This will:

• Keep the server's public IP address private.
  
• Remove the requirement to port forward the server to display in the Server Browser.
  

If you prefer to continue displaying your server's real IP address in the server browser then add the following startup option to keep previous behavior:

-nofakeip

Clients will still attempt to connect via the SDR by default even with -nofakeip. If the server has -nofakeip and the client has cl_sdr_prefer disabled, the connection will not use the SDR - as it worked by default before this update.

Due to a possible Steam bug, servers using an anonymized IP address will not show up in the Steam Client's Server Browser, but it will show up in Synergy's in-game server browser. -nofakeip can be used to workaround this.

[h3]Listen Servers[/h3]
Listen servers are unchanged and will work as they did in the previous update (i.e. connect ). UI updates are still in progress to make playing with Steam friends easier.

Happy New Years!

[h2]Steam Networking (beta) [/h2]
This update includes backend netcode support for Steam Networking. This means you can play Synergy with your friends without the hoster needing to port forward their listen client or dedicated server. UI changes to help facilitate this are currently in progress.

[h3]How can I use it now?[/h3]
Whoever will be hosting the server simply needs to load into a map and provide their SteamID64 to their friends. Type status in the console while loaded into a map to get your SteamID64.

This will be one of the lines printed:

steamid : [A;1;123456789:03210] (01234567890123456)

This is your SteamID. The SteamID64 is the one in parentheses: (01234567890123456). Send this to friends who would be connecting to your server.

To connect to a friend's server, type the following into the console given your friend's SteamID64:

connect 01234567890123456

This works with dedicated servers as well. When a dedicated server loads a map, it will also provide a game server SteamID64 via the status command. However the game client's Server Browser does not support listing servers via SteamID yet.
