A little bit about me and this project/Disclaimer
I have been coding and learning how to code since the start of 2026, so I am still new and learning as I go. Please do not assume every part of this project was made by someone with years of experience.
~~AI tools were used for the thumbnail/icon because~~ I have no real experience with art or digital art design. ~~If anyone wants to make genuine custom art for the icon, let me know and I will credit you.~~
New Icon/Thumbnail was hand made by "Noint" a special thanks to them and the icon they made, they're awsome ^w^
AI assistance has also been used while working on this project for things like organization, planning, debugging, understanding/fixing errors. Unless clarified the rest is not AI. Apologies in advance for any misunderstanding or lack of clarification.
A fully playable casino. Try your luck, and spend your hard-earned Crowns across three games — all fully multiplayer synced.
IMPORTANT — This mod contains a DLL file
AtlyssCasino is both a map and a plugin at the same time. The download contains:
- atlyscasino.mapbundle — the casino map scene loaded by MapLoader
- AtlyssCasino.dll — a BepInEx plugin that runs all gameplay logic (slot machines, blackjack, roulette, entry fee, exit trigger, multiplayer sync)
Both files are required. The map does nothing without the DLL, and the DLL does nothing without the map. Install both into your BepInEx/plugins folder as you would any other mod.
AtlyssCasino also requires MapLoader, CodeYapper, and Easy Settings API.
Configuration
AtlyssCasino includes an Atlyss Casino tab through Easy Settings API.
Configuration is meant to be set before loading into a session. Once a player/session is loaded, the settings UI locks so casino rules are not changed mid-lobby.
Gameplay settings are owned by the lobby host or dedicated server. Clients cannot change the host's casino rules from their own settings menu, and host-owned gameplay values are synced to clients when the casino loads.
Headless/dedicated servers can edit the generated BepInEx config file directly after first launch.
Configurable settings include entry fee, walk-away penalty, blackjack turn timeout, roulette AFK timeout, payout multipliers, allowed bet amounts, floating table info display, blackjack/roulette game UI options, client performance options, client audio options, controller interact options, optional controller command macros, and separate routine client/headless log suppression. Log suppression only hides casino info/debug/message output; warnings and errors stay visible.

Install & use Install: follow the bundled instructions
- Unzip the archive from playbuff and read the bundled readme / instructions first.
- Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
- For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
- Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.
Install locations vary a lot between mods — the bundled readme is the most reliable guide.
Install these first, or the mod will not work:
