EconomyMod

Overview

EconomyMod is a NeoForge-based Minecraft mod designed to introduce a lightweight in-game economy system, using emeralds as the primary currency. It enables players to manage virtual balances through intuitive commands, with persistent data storage to maintain progress across server restarts or player sessions. The mod is compatible with Minecraft 1.21.1 and integrates seamlessly with NeoForge's modding ecosystem.

Core Features

1. Currency & Balance Management

• Emeralds as Currency: Uses Minecraft's vanilla emeralds (Items.EMERALD) as the base currency, bridging in-game items with virtual balances.
• Virtual Balance: Players can store emeralds in a persistent virtual balance, separate from their inventory, to avoid inventory clutter.

2. In-Game Commands

All interactions with the economy system are handled via chat commands:

Command	Syntax	Description
Deposit	/deposit <amount>	Converts <amount> emeralds from the player’s inventory to virtual balance. Fails if the player has insufficient emeralds.
Withdraw	/withdraw <amount>	Converts <amount> emeralds from virtual balance to the player’s inventory. Fails if balance is insufficient or inventory is full.
Check Balance	/balance	Shows the player’s current virtual balance.
Check Others’ Balance	/balance <player>	(Admin-only, requires permission level 2) Shows the virtual balance of a specified player.
Transfer	/pay <target> <amount>	Transfers <amount> emeralds from the sender’s virtual balance to the target player’s balance. Fails if the sender’s balance is insufficient.
Settings	/setbalance <player> <amount>	command to set a player's emerald amount (admin)

3. Persistent Data Storage

• Player balances are saved locally in the economy_data/ directory (created automatically) as .dat files, using Minecraft’s NBT (Named Binary Tag) format for reliable serialization.
• Data is loaded when a player logs in and saved when they log out, ensuring balances persist across server restarts or player sessions.
