Server cook

In the editor, open the Network panel, go to the Server tab, optionally type rule overrides (key=value pairs) and press Cook Dedicated Server.... From a script or build machine:

• KroysDedicatedServer.exe and what it needs.
• Content: the startup scene cooked through the same pipeline as the game, with terrain, collision, skeletons, animations and the baked navmesh, but no textures, materials or audio.
• The game's native game module, when the project names one, with its default rules.
• GameRules.kserverrules: the session rules as key=value text. The engine reads server_name, game_name, map_name and max_players (shown in server lists); every key is available to the rules through GameSession.GetSetting.
• StartServer.bat, which starts the server with the right options.

Copy the folder to the server machine and run StartServer.bat. Rules written as a C# game mode run from the game's script assembly: copy the published scripts next to the server and add --script-assembly and --game-mode to the start line (Dedicated server). Override a rule at launch with --rule key=value, for example --rule bots=8. Open UDP 7777 for players across the internet; the local network finds the server by itself.

See Dedicated server for every option and Game modes and bots for writing the rules.
