Thank you for the amazing update, Kjun, my deepest appreciation goes out to you and the entire inZOI team for the love and dedication you pour into this game every single week. The water spill mechanics shown in the latest video genuinely excited me – not just as a fun moment, but as a glimpse at something much deeper: a systemic liquid surface effect layer that could make inZOI’s beautiful world feel even more alive.
Games like Baldur’s Gate 3 and Dead Island 2 have shown how far surface effect systems can go – liquids, oils, corrosives (acid, alkaline), ice, blood, all interacting with the environment and each other in cascading ways. inZOI already has the foundation and the example with the slippery puddle and the PC electrocution hazard are great first steps. Here are some directions I’d love to see it grow in:
Water
- Puddles should reflect light realistically – especially beautiful at night with ray tracing
- Puddles gradually evaporate over time unless replenished — especially outside and in hot weather
- In cold weather, puddles can freeze into ice patches – ice should carry a significantly higher slip chance than regular water unless a Zoi throws salt on them (a job for municipal service NPCs)
- Wet floors should not always make every Zoi slip – it would feel more realistic as a chance-based system, like a dice roll affected by the Zoi’s fitness level and emotional state, the size of the puddle, and the floor material itself (marble becomes extremely slippery when wet, carpet barely at all)
- Wet footprints tracked across clean floors, leaving a visible trail
- Mopping removes puddles and wet surfaces
- Pouring water on Zois who are passed out or sleeping on the floor wakes them up
- Water can extinguish fires and prevent soaked objects and floor tiles from igniting
- Water can wash away other surface effects such as oil or dirt
- Watering empty lawn should have a small chance of spawning random weeds, flowers, or mushrooms overnight (many new collectibles!)
- Garden sprinklers should be able to actively hydrate nearby plants, and where the water spray hits solid surfaces like pavement or flooring, it should create realistic interactive puddles
Other Liquids
- Cooking oil in the kitchen – slippery and flammable, a realistic domestic hazard with potentially serious consequences
- Coffee or drinks accidentally spilled on the floor or electronics – an accident that can happen organically during normal gameplay, especially for clumsy Zois
- Paint buckets as physics objects that can be accidentally or mischievously knocked over, creating a wet paint surface that leaves colorful footprints wherever Zois walk through it
- Food and drink spills left unattended for too long have a chance to attract insects or rodents – especially relevant once pets and other animals arrive
- Knockout pills dissolved into a drink – a direct way to incapacitate a Zoi, and a new way to commit crime, or an opportunity for a hero to warn the potential victim and knock out the bad guy – preferably with a bottle of a strong drink, which can break and spill a flammable alcohol surface
- A fuel jerry can for creating highly flammable gasoline trails and puddles – combine with matches for insurance fraud
Cross-System Interactions
- Water + fire = steam, reducing visibility in the room
- Water + electricity + multiple nearby Zois = chain electrocution
- Gasoline/oil + electricity/heat = ignition, making electrical hazards or very hot objects doubly dangerous near a jerry can or oil barrel
- Oil + fire = an accelerated blaze that burns hotter and is significantly harder to extinguish (do not try pouring water on an oil fire – really, not a good idea)
- A wet Zoi caught in freezing temperatures should have a much higher chance of catching a cold
- Driving a car over wet surfaces should influence handling. Driving over ice or oil even more so.
- Knocking out a Zoi (with a frying pan, baseball bat, or other melee weapon) who is holding a drink, watering can, jerry can, or other liquid container, should spill the liquid on the floor
- Liquid trails as physical evidence in player-driven mystery or crime quests
- A blood surface effect when Zois are severely injured in fights (frying pan to the head) – slippery, and visible evidence prompting reactions from other Zois and police
- Bleach or cleaning products as a way to destroy liquid evidence, for smart criminals to cover their tracks
I truly hope these suggestions help in expanding what inZOI is already becoming – a world where every character, every location, every object, every surface, and every action feels meaningfully connected.
