- Click a need bar and your Sim takes care of it. Left and right-click both work by default, but if testingcheatsenabled true is active, left-click stays reserved for vanilla drag-to-fill, so use right-click for Motive Click.

- Hunger: Sims go for prepared food first, then check the fridge for leftovers. If there aren't any, they cook a meal or grab a snack depending on how hungry they are. Away from home they eat whatever food is in their inventory (potions and poisoned apples are ignored), or head to the nearest bistro or diner if they’re carrying nothing. Occults are covered as well: Vampires drink plasma, Mermaids top up in a pool or the ocean, etc.

- Hygiene & Bladder: A slightly dirty Sim washes their hands or brushes their teeth at a sink, while a really dirty one takes a shower or a bath. For Bladder they head to the nearest free toilet. Sims never walk in on anyone - if the bathroom is taken, your Sim waits outside and goes in once it's free. Locked rooms and single-gender doors are respected as well.

- Energy & Fun: A slightly tired Sim takes a quick nap on a sofa or bed, while an exhausted Sim goes to bed for a full sleep. For Fun they watch TV, listen to music, read, play a video game and more.

- Social: Friendly, funny or romantic interactions are picked from relationships and traits. Risky ones like Try for Baby or Break Up are never used. With nobody around, your Sim calls a friend for a chat.

- Pets: animals are looked after in the same way, from food bowls and hay to litter boxes, scratching posts, chew toys, pet beds, and other items.

- It's a lightweight script mod. It doesn't override any core game files or write to your save file, so it's 100% safe to add or remove anytime.
