[0.1.0] - 2025-Dec-23

Added

  • Added a configuration file under BepInEx/config/FleesDedicatedServer.cfg as an additional option to specify dedicated server settings
  • Added an option to schedule a server restart after a specified amount of time
    • The automatic restart can be configured to go through only when the server player count drops below a certain percentage of the maximum player count
    • The time interval is specified in the [XXd][XXh][XXm][XXs] format, such as 4h for 4 hours, 1d6h30m for 1 day, 6 hours and 30 minutes, etc.
    • The minimum time interval is 30 minutes
  • Added /restart to the server console - this will restart the server after 20 seconds have elapsed
  • Added /cancelrt - this command and /cancelsd will cancel a pending server shutdown or restart
  • The mod will now generate start_dedicated_server.cmd on Windows and start_dedicated_server.sh on Linux with Proton
    • These scripts can be used to launch a dedicated server directly instead of having to specify launch options through Steam
    • You will need to first launch the game normally using this mod for those scripts to appear or be updated
  • The mod will now generate steam_appid.txt to allow to boot the game without going through the Steam Client

Changed

  • In-game audio is now muted while running with -batchmode -nographics
  • The host player is now hidden from view instead of being teleported in an off-screen area
