Coin System

🔥 Black Market System Added A brand‑new Black Market system has been introduced, allowing players to sell and buy items directly inside the economy. This update brings multiple new mechanics and expands the core gameplay loop of the mod.

✨ New Features

1. Item‑Based Selling Modes Players can now choose how each item should be listed:

Fixed Price Mode — the seller sets a static price

Auction Mode — the seller defines a starting price and duration, and players can bid on the item

This choice is made per item, giving players full control over how they want to sell their goods.

1. Auction System Auctions now support:

Starting price

Auction duration

Live bidding

Automatic coin locking

Refunds for outbid players

Automatic winner selection when the timer ends

Automatic item delivery to the highest bidder

Automatic coin transfer to the seller

If no bids are placed, the item is returned to the seller.

1. Custom Price Input (Anvil Input) When listing an item with a fixed price, players can:

Use a suggested price

Or enter their own custom price via an Anvil input screen

This allows precise pricing without complicated menus.

1. Reclaiming Listed Items Sellers can now reclaim their own items from the Black Market.

Reclaiming costs a configurable fee (percentage of the original price)

If the seller cannot afford the fee, the reclaim is denied

Items are safely returned to the seller’s inventory

This prevents abuse while still giving players flexibility.

1. Admin Fee Configuration A new admin command has been added:

Code /blackmarket setfee <percentage> This allows server owners to define how expensive reclaiming should be. The fee is saved in the Black Market config and persists across restarts.

1. Full Persistence System The entire Black Market is now saved and loaded automatically:

All listed items

Auction data

Bids

Sellers

Reclaim fee

Auction timers

Everything is stored in a JSON file inside the mod’s config directory.
