MCA Reborn:Supermarket Life

Players build a supermarket by placing a checkout counter, and the mod defines the store area automatically within a 24-block radius around that counter. Business data is kept in the checkout counter's block entity. Display shelves and 27-slot stockroom crates hold merchandise, and items appear on the shelves according to how many inventory slots are occupied.

Villagers can be hired into five roles that cover the running of a store, from ringing up purchases to guarding the floor. Each employee follows an individual work shift, keeps a family life of their own and reports regularly on work. Regular villagers also wander into supermarkets and buy goods through the mod's built-in economy, with prices set on a PriceBook ledger that deposits revenue at the nearest checkout counter.

The add-on builds on Minecraft Comes Alive (MCA) and its villager family and relationship systems, and the employees integrate with MCA's villager AI. Banking is included: an ATM block requires a bank card and PIN, while the staff-assisted bank counter handles card replacement, loss reporting and loans. The mod is published for NeoForge on Minecraft 26.2 and runs on client and server, so the server and every player need it. Its code is released under the MIT License, and it is not open source.
