🖧 ATLYSS Dedicated Server Plugin

Now updated for the latest ATLYSS version.

This BepInEx plugin adds headless dedicated server support to the game ATLYSS, enabling you to run the game in a terminal as a dedicated server — no graphics or UI needed.

⚠️ This is for hosting servers only. It will disable itself when the game is being launched normally.

✅ Mod Compatibility

Fully compatible with other BepInEx mods that modify or enhance hosting behavior.
This includes:
- Chat formatting mods (e.g., colored messages)
- Uncapped party size or connection limit mods
- Custom stat or balance changes
- Lobby tweak plugins

As long as the mod loads under BepInEx and applies during host/server initialization, it will work seamlessly with this dedicated server plugin.

🔍 Known Bugs

Console input does not echo back while typing.
When using the BepInEx console, typed characters may not appear on screen. However, input is still being received and processed correctly — pressing Enter will submit the full command.
No feedback for partially typed commands.
Since input isn't echoed, it's easy to lose track of what you've typed. To mitigate this, commands should be typed carefully and can be confirmed once submitted.

✅ Requirements

ATLYSS game

-batchmode -nographics -server

🧠 Behavior Notes

The host is teleported to the fishing area 30 seconds after spawning.
Server shuts down 5 seconds after host stop (clean shutdown).
In-game chat is mirrored to the terminal (color tags handled).
Console input works for typing commands directly.
Audio is disabled via AudioListener.volume = 0.
Server config and startup logs are shown in the console.

🧪 Troubleshooting

❌ Server disappearing when trying to join? Make sure you have a character saved in slot 0, or specify a -hostsave slot when starting.
❌ Nothing happens? Make sure you're running with -batchmode -nographics -server
❌ Can't see the terminal? Run the game via cmd.exe or a .bat script
❌ Server name reset? Must be under 20 characters
