Simple Banking

Simple Banking is a Vault-enabled, scoreboard-driven bank plugin for Spigot servers. Players deposit a configurable currency item (and optionally its block form) into shared "Bank Chests" but maintain per-player balances. Withdrawals convert bank balance back into items and blocks based on a configurable multiplier.

Features

• Per-player balances stored in config.yml
• Configurable currency: item and optional block with multiplier (e.g., 1 DIAMOND_BLOCK = 9 DIAMOND)
• Deposits via:
  • Shift-click into Bank Chests
  • Cursor click onto Bank Chest slots
  • Hopper transfer with per-hopper owner tracking
• Withdrawals split into blocks first (to save inventory slots), then leftover items
• Live scoreboard updates in tab list and below player names
• Vault Economy provider for compatibility with other plugins
• In-game currency management command with autocompletion for minecraft:[item]

Requirements

• Server: Bukkit/Spigot/Paper 1.21.x
• Java: 17+
• Plugins: Vault

Installation

1. Ensure Vault is installed.
2. Copy simplebanking-<version>.jar into your server plugins/ directory.
3. Start the server. The plugin creates default config.yml.
4. Verify startup logs show:
   • Registered SimpleBanking as Vault provider
   • Simple Banking enabled / account count

Configuration (src/main/resources/config.yml)

players: {}
bank-chests: []
currency:
  item: DIAMOND
  block: DIAMOND_BLOCK
  block_multiplier: 9
  name_singular: Diamond
  name_plural: Diamonds

• currency.item: Base item material ID
• currency.block: Optional block material ID; omit to disable block deposits/withdrawals
• currency.block_multiplier: Units per block
• name_singular / name_plural: Display names used in scoreboard and messages

Changes are persisted automatically when using /currency; manual edits require a server restart or configuration reload.

• /givebankchest
  • Gives a tagged chest that becomes a Bank Chest when placed

• /currency <item> [block] [multiplier] [singular] [plural]
  • Changes the currency item and optional block/multiplier and display names
  • Autocompletes as minecraft:[item] for first arg and minecraft:[block] for second
  • Requires all player balances to be zero before change
  • Permission: diamondbank.admin

Permissions

• diamondbank.admin: Admin tasks like giving Bank Chests and changing currency (default op)
• diamondbank.withdraw: Allows withdrawals (default true)
• diamondbank.balance: Allows viewing the leaderboard (default true)

How Deposits Work

• Bank Chest placement: placing the given chest item registers the location as a Bank Chest
• Manual deposits:
  • Shift-click: moving currency items/blocks from inventory into a Bank Chest credits units
  • Cursor click: placing currency items/blocks into Bank Chest slots credits units
• Hopper deposits:
  • Hoppers track owner via persistent data when placed
  • Moving currency items/blocks into a Bank Chest credits that owner’s balance
  • If owner is unknown, credits the nearest player within 16 blocks

Scoreboard

• Displays currency plural name (e.g., "Diamonds") in tab list and below player names
• Updates on every deposit/withdrawal and player join

Vault Economy

• Implements Vault Economy for compatibility; account balance maps to bank units
• No bank accounts (only player accounts). Vault bank-related methods return NOT_IMPLEMENTED

Troubleshooting

• Invalid plugin.yml:
  • Ensure no non-ASCII/control characters; fix and rebuild
• Scoreboard class errors:
  • Must import org.bukkit.scoreboard.Scoreboard and ScoreboardManager
  • Always restart server after updating the plugin to avoid stale classes
• Duplicate JARs:
  • Remove old copies (e.g., both SimpleBanking.jar and simplebanking-<version>.jar) to prevent classpath conflicts
• Currency change blocked:
  • /currency refuses changes if any player balance > 0; have players withdraw first and retry
