Once you have that, in a command line, or by making a .bat file in the same directory as steamcmd.exe, run the following: ``` steamcmd +force_install_dir C:\MyServer\sboxserver +login anonymous +app_update 1892930 validate +quit ``` Alternatively, you can use the default `sbox-server.exe` in your Steam sbox directory. Once downloaded, to launch the server, you would typically do something like this in some kind of .bat file (see the next section for more information on how to configure your server): ``` sbox-server.exe +gamemode facepunch.sandbox +map facepunch.construct +maxplayers 8 +hostname "My Epic Server" ``` ## Dealing With Updates You will have to re-run steamcmd every time s&box updates in order to update the server to the latest version; players will not be able to join if they are running on a different version of the game to your server. This poses a problem since currently s&box updates many times each day. One way around this is to use a .bat script that restarts and re-updates the server at regular intervals: ``` :loop C:\MyServer\steamcmd.exe +force_install_dir C:\MyServer\sboxserver +login anonymous +app_update 1892930 validate +quit start "" C:\MyServer\sboxserver\sbox-server.exe +gamemode facepunch.sandbox +map facepunch.construct +maxplayers 8 +hostname "My Epic Server" timeout /t 3600 /nobreak taskkill /im sbox-server.exe goto loop ``` This script will restart the server every 3600 seconds (every hour). The downside of this is that it will forcefully close your server. For most games, this probably doesn't matter. But, if your server was doing I/O operations at the time like saving to file, this could lead to data corruption. The only guaranteed way to prevent this is to make sure your gamemode is not doing any I/O at the time the process is killed. Since you know your server is going to be restarting every hour or so, you could do this by implementing a `TimeSince` that stops I/O operations during the last minute. ## Shutting Down Gracefully You can shut down your server gracefully at any time by typing `quit` into the console. ⤶ ## It's Crashing11!!⤶ ⤶ Sometimes the dedicated server will crash for no apparent reason. Trying the following might help:⤶ ⤶ - Make sure you're actually updating your server to the latest version using the steps above.⤶ - Make sure your gamemode actually works.⤶ - Check /logs/Log.log for clues.⤶ - Update s&box and re-upload the gamemode to asset.party. Sometimes updates to s&box require the gamemode to be rebuilt.⤶ ⤶ If all else fails, file a bug report, preferably with logs.⤶ ⤶ # Launch Configuration As with any Source dedicated server, when launching you can use convars to customize your server settings. To load a game and a map, specify its organization and identifier - you can find them by browsing [asset.party](https://asset.party/) This is a list of some of the more useful convars. | convar | Behaviour | Example | |---------------|---------------|----------| | +gamemode | Sets the gamemode. | +gamemode facepunch.sandbox | | +map | Sets the map. | +map facepunch.construct | | +maxplayers | Sets server's player limit. | +maxplayers 8 | | +hostname | Sets the name of the server. | +hostname "My Epic Server" | | +extensions | Loads addons onto the server. Each addon is separated by a semicolon. | +extensions "gvar.admin_ball;gvar.sbox_radio" | <note>If you're getting an engine.dll not found error when launching the server you most likely will need to install _CommonRedist/vcredist/2022/VC_redist.x64.exe</note> <note>If the command prompt instantly closes when running the .bat you are most likely missing the .net runtime environment, you can get the required v7 version from here: https://dotnet.microsoft.com/en-us/download/dotnet/7.0</note> # Connecting Players connect through your server's Steam ID, so there's no need to worry about port forwarding or anything. You can connect to your server via the global server list or the gamemode server list: <upload src="4a1b3/8dabffbe4044f2d.png" size="25123" name="image.png" /> If you're lost, or if you can't find your server, you can use the `connect` command with your server's ID as an argument. You can find the ID by typing `status` in the server's console at any time. Sometimes it can take a few minutes for your server to appear in the server browser. # Hosting Unreleased Content It seems to be the case that you can host dedicated servers for gamemodes that are not public on [asset.party](https://asset.party/). This is useful because it means you can host your gamemode whilst stopping it from showing up in the games list. The downside to this is that it presumably means that other people can host your unreleased content with a dedicated server too. Although, in practice, no one is likely to care enough to do this.
