A concept where the shop stock is built by players.#750

Say if a player could sell an item to the shop, the stock of that item increases so there isnt inf stock or a restocking every once in a while, but a stock built by players. Like if someone wants to buy fish but theres no stock, a player whos a fisherman could sell fish to the shop to increase stock so others can buy.

tho there’s a workaround to this i do think it’d be nice to make the shop system more interesting and to avoid having users create their own customized shop when there’s already a shop with mimu

i believe a way this could work would be with functions similar to {modifyinv:} but instead it would be something like {modifystock:ITEM|AMOUNT}
