Village Business

The mod adds a Sales Stand block that can hold almost any item. Villagers visit the stand from time to time, and when they do they may hand over emeralds in exchange for the items inside. Each item has its own price, and the chance of a sale depends on how long it has been since the last visit and on how desirable the item is to villagers. Items that villagers want more often, such as food, sell more frequently than items they rarely buy, such as boats.

A second block, the Request Stand, works the other way. The player sets a requested item by placing it in the request slot and loads the stand with emeralds. Villagers occasionally come to the stand and give the requested item in exchange for emeralds. Villagers rarely sell items at a price lower than the player would pay for them, so the Request Stand is a way to obtain items that are hard to buy from villagers directly. Both stands accept a redstone signal that closes the shop and stops villagers from buying, which lets the player pause a shop or automate its input and output with item-handling blocks.

Village Business is a Fabric mod for 1.20.1 – 1.20.5, released under the MIT License and open source. It is needed on both the server and every player's client, because the stands and the trading logic run on both sides. Its source code is public.
