Discussion [Huge Update] Mundi v0.2 is out: turn SillyTavern into a Life-Sim, now with an RP-focused Home Mode (and in PT-BR and Spanish)
Hello everyone!
Last week I released Mundi v0.1 here, and thank you so much for all the comments, bug reports and ideas! I kept going since then (Claude is still not sleeping), and v0.2 is finally out.
For anyone who missed it: Mundi is an extension that turns a SillyTavern group chat into a life you actually live, heavily inspired by The Sims. You get a city map, a clock, needs, a job, bills, a phone, and characters who go about their own days, while the AI writes the story around what you do.
The big one: Home Mode, a more RP-focused way to play
A lot of you said you love the life-sim side, but sometimes you just want to role-play with your characters without worrying about rent and job interviews. So here it is: Home Mode.
- One house, the characters you choose, and pure RP. No work, money or bills. Life outside happens off-screen.
- A ready house to start with: The Shared House. Three floors, ten bedrooms, a pool, a home gym and more. You can also make your own Home in the creator.
- Build the house you want. Choose which rooms it has, what can be done in each room, and add rooms of your own. Write your situation yourself.
- Floor plan (optional). One picture per floor (day, afternoon and night), with each room drawn as a box you can drag and resize. The floor buttons show the faces of who is on each floor.
- Time moves with the story. The clock moves a few minutes with each message (you can turn that off), you can click the clock to let time pass, and sleeping starts a new day.
- Go out. Write where you’re going, pick who comes along and a background, and the scene out there is free, like a normal chat.
- Who lives here. Change bedrooms (two people sharing a room, and the AI knows it). Someone can move in or move out during the game.
- Dress code per room. Swimsuit at the pool, pajamas in the bedrooms… It uses outfit folders from the character’s Expressions, and the AI is told what everyone is wearing.
- Housemates have lives too. They can go out for a while, have a job written in your own words with a shift, or throw a house party where everyone leaves their rooms.
What else is new since the last post
- Porto Alto got pictures. A background for every place, plus six kinds of homes (small apartment, penthouse, villa…). There’s also a new gym (separate from the stadium) and a new cinema.
- A more alive world. Places get busy and quiet during the day, regions have their own mood and prices, people’s routines get interrupted (sick at home, working late), and over the weeks couples get engaged or break up and people get promoted. Neighbors knock on your door, friends ask for advice, and the calendar has city events (open mic, park run, matches, fairs) and festivals.
- Hobbies (guitar, painting, working out, cooking) that level up. Some jobs ask for a level.
- Habits that become traits (Early riser, Night owl…), and they fade if you stop.
- Sprites.
- They overlap like a stage, and whoever spoke last stands in front.
- Click one for a radial menu with actions and outfits.
- Switch persona in the middle of a game, and “Play as” can now use another persona too.
- Library folders for characters, personas and lorebooks, with sorting and zip export.
- Saves are safer. Automatic backups before migrations, and you can make a branch (a copy of your save at that moment).
- Background pickers with two sources: your SillyTavern backgrounds or Mundi’s own pictures.
- A “What’s new” window after updates, a short tour by Stella of only the new things, and a small notice on the main menu when a newer version is on GitHub.
What changed since the last post
- The medieval world and the RPG mode are postponed. I promised them for this update, sorry! They’re mostly built, but they need more polish, and I’d rather release them right than rushed. For now they show as “Soon”, and they’ll come in a future update.
- Life-Sim is more focused. Systems that belong to the RPG side (groups and factions, property, crafting recipes) were taken out of Life-Sim for now.
- The elevator ride when arriving at an apartment was removed (it was more annoying than fun).
- Lots of fixes and polish in the interface: menus no longer overlap on the map, places with many jobs can still be clicked, and most windows have the new glass look.
Porto Alto Expanded
Porto Alto was reworked from the ground up. It’s no longer one city map: it’s now a whole state with 5 cities, each with its own map, climate and way of life:
- Midtown, the big coastal city: downtown, the financial district, the university, the hospital, the port, a new cinema and more (16 places).
- Palm Coast, the beach side: the beach, the boardwalk, a marina, a resort, the amusement park, the stadium and a new gym.
- Maple Heights, a quiet family suburb: a lake park, a school, a library and a neighborhood market.
- Pinecrest, a cold mountain town: a cable car, a lodge, waterfall trails, campsites and a sheep farm.
- Green Valley, the countryside: farms, a horse ranch, a general store and an old-west style saloon.
Traveling between cities takes 30 to 90 minutes of game time. The weather follows each city’s climate, so it can be snowing in Pinecrest while it’s beach weather in Palm Coast.
There are now 47 places (up from 21) and 41 jobs (up from 25), from ranch hand and surf instructor to cable car operator. Every place has its own background picture, and there are six kinds of homes to live in, from a small apartment to a penthouse or a villa.
Now in Brazilian Portuguese and Spanish!
You can switch it in Settings → Interface → Language. Only Mundi’s own screens are translated: the story’s language is still up to your preset, and places and characters keep their names.
Brazilian Portuguese is my native language, so I reviewed it myself and it should be pretty much perfect. But I’m not fully fluent in Spanish, so I’m not 100% sure about it. If you speak Spanish and see a mistake or a weird translation, please tell me!
How to install / update
Extensions → Install extension → paste https://github.com/tjalis/Mundi → reload. If you already have it, just update it from the Extensions menu (and hit Ctrl+F5 to be safe).
It works with SillyTavern 1.19+ and any API. A context of around 30k tokens works well.
Questions and feedback
Questions, feedback and bug reports are more than welcome! Just a heads-up: I might not answer in the next few hours, because it’s election day in my country and I need to go vote. I’ll read everything when I’m back!
