Welcome to the Coin-System- wiki!

CoinSystem is a lightweight but feature-rich economy mod for Minecraft servers.
It adds coins, a fully UI-based shop, a duel system, mob rewards, and death coin penalties.

This page explains how the mod works and how to use all features.


1. Coins and Basic Usage

Coins are the main currency of the mod.

Check your coins

  • /coins
    Shows your current coin balance.

  • /bal
    Shows the coin balances of all online players.

Send coins to other players

  • /pay
    Sends coins from your balance to another player.

If you don’t have enough coins, the payment will fail.


2. The Shop System (UI Only)

The shop is fully UI-based.
There is no text list anymore — everything happens inside the UI window.

Open the shop

  • /shop
    Opens the shop UI.

Buying items inside the UI

Inside the shop UI:

  • Left-click an item → buys 1 of that item
  • Shift + Left-click → buys 64 of that item

Buying items with commands

You can also buy items using commands:

  • /buy → buys 1
  • /buy 64 → buys 64
  • /buy → buys any custom amount

Inventory check

When buying items, the mod checks the player’s inventory:

  • If there is enough space → all items are given
  • If there is not enough space → the inventory is filled as much as possible
  • The player is only charged for the items actually received
  • No coins are taken for empty space or missing inventory slots

The shop UI automatically displays all items that admins add to the shop.


3. Duel System

Players can challenge each other to duels with coins as the wager.

Start a duel

  • /duel
    Sends a duel request to another player.
    The challenger decides the wager amount.

Respond to a duel

  • /duel accept
    Accepts the duel.

  • /duel decline
    Declines the duel.

Duel outcome

  • The loser loses the coins they wagered
  • The winner receives all coins (their own wager + the opponent’s wager)

The invited player cannot change the wager amount.


4. Mob Rewards

You can configure how many coins each mob gives.

Show mob rewards

  • /mobrewards
    Opens the mob reward UI.

Configure mob rewards (admin)

  • /setmobrewards
    Opens the mob reward UI.
    The <amount> defines how many coins the selected mob will give.

Inside the UI:

  • Each mob is represented by its spawn egg
  • Clicking a mob sets its reward to the amount you entered in the command

Example:
/setmobrewards 10 → open UI → click Zombie → Zombies now give 10 coins.


5. Death Coin Penalty

You can configure how many coins a player loses when they die.

  • /setdeadcoins
    Sets how many coins a player loses on death.

If set to 0, players keep all their coins.


6. Admin Shop Management

Admins can fully control the shop using commands.

Add an item to the shop

  • /addshopitem
    Adds an item to the shop with buy and sell prices.

Remove an item from the shop

  • /removeshopitem
    Removes the item from the shop.

Change prices

  • /setbuyprice
    Changes the buy price.

  • /setsellprice
    Changes the sell price.

The shop UI updates automatically.


7. Admin Coin Control

Admins can directly modify player balances.

  • /addcoins
    Adds coins to a player.

  • /setcoins
    Sets a player’s coin balance to an exact value.
