Minecraft Exchange

Minecraft Exchange is another economy and shop mod, however what makes this different is I've built it to act like the RuneScape Grand Exchange, this mod allows you to shop completely natively between different mod packs, blocking the player from seeing or buying modded items that are not available to them.

This mod is meant to be used by players with the global market config option, but allows multi modpacks servers to add there own database details meaning they can link up there worlds with one economy and shop without the worry of multiple plugins or mods for handling.

WARNING: This mod is currently in development. It probably will contain bugs.

Features

The Grand Exchange Broker: Right-clicking with a Broker's Ledger in hand will summon a Broker in a puff of smoke, allowing you to instantly access the market GUI from anywhere.
Market GUI: Buy and sell items with an interface that tracks your active listings just Like the Grand Exchange.
Custom Mob Drops: you can get coins as loot drops:
- Copper Coins: from Zombies and Skeletons.
- Gold Coins: found in abandoned mineshafts.
- Silver Coins: found in other chests.
Three Configurable Storage Modes: Choose exactly how your server's economy is saved (Local, Global, or Custom MySQL).

For Server Owners

Being the owner of multiple servers in the past, I know how quickly server currencies and player shops can become a real headache. My design is influenced by RuneScape and lets the players just build the market but the database learns from sold items and eventually starts recommending prices.

Here is what I put into my mod To help servers.

I thought hard about possible dupes, and put things in place to stop all the common ones, but we know players and they might find away, if they do let me know and I'll be on it asap.

If a sale failed it will give the items back so no lost items

I've added cooldowns and disappearing mechanics for the entitys my mod spawns.

To deal with spamming database I've limited buy & sell slots to 6 just like the Grand Exchange.

Modpacks

Yes, you are completely free to use this mod in your Modpacks!

Planned Features

Implement an API: Right now other mods can hook into the money as the methods are public, but I want to create dedicated, safe APIs for it.
UI and Item Model Overhaul: I'm not an artist, so creating models and textures takes me ages. I wanted to get the backend code and database thoroughly tested first, so I am using simple models for now.
Coin Withdrawal: Right now you can deposit physical coins that you find in the world, however, there is currently no way to withdraw your digital balance back into physical coins.
Buy Orders: I want the market to have a true RuneScape feel. However, I first need to fully test the capability of multiple users selling items from different modpacks and whether my code is truly stopping the viewing of items that are not loaded in the buyer's game.
Admin Commands and Management: While it is easy to add these commands, I want to fully test how easy it is to make money natively in survival first. I do plan on adding full management commands for admins in the future.
Listing Expirations: Currently, an item listed on the market will stay there forever until it is sold or cancelled. I plan on adding a system where listings expire after 7 or 14 days and return to a "collection box" to keep the market active and clean.
Price History / Trending Indicators (Global Only): While I currently save the prices that players are paying for items, I purge this data weekly to maintain competitive prices and leave choices up to the players. Eventually, I want to implement a UI feature that will correlate all this data and show users historical trending prices.
