InfiniteBags | Backpack with Shop

InfiniteBags
Bottomless. Sortable. Sellable.
Premium quality-of-life storage. Part of the Modern Plugin Series by zArrowTan.

What is InfiniteBags?

Vanilla inventories fill up. Ender chests fill up. Shulkers fill up. InfiniteBags doesn't.

Every player gets a personal bottomless backpack that lives in your server database, not their hotbar. Items go in and never spill out, each slot holds trillions of a single item type, auto-pickup routes loot straight into the bag, and a one-click sell button turns it all into economy currency. It's the storage plugin built for serious survival, skyblock, and prison servers.

Features

Bottomless Storage

No stack limits: each slot holds trillions of one item type. Deposit stack after stack and they merge into a single slot with a running quantity.
Multi-page GUI: up to 45 slots per page across multiple pages, with navigation, search, and settings in one window.
Progressive slot unlock: pages grow as players deposit, so the bag scales naturally with use.

Auto-Pickup

Items the player walks over route straight into the bag instead of the vanilla inventory.
Toggle globally with /bag pickup, per-slot with F in the GUI, or with a click in the bag.

Sell From Your Bag

Sell a single slot with shift + right-click, or hit the emerald Sell-All button.
Sell-All opens a confirm GUI with a full per-item value breakdown, sorted by worth.
Multi-shop support: UltimateShop, ShopGUI+, EconomyShopGUI, and EssentialsX, plus a local shopworth.yml fallback. The first provider with a price wins.
CustomModelData pricing: price custom items from ItemsAdder, Nexo, Oraxen, MMOItems, or plain resource-pack items using the cmd-prices: section in shopworth.yml. Format: MATERIAL:CMD: price. Lookup order: CMD, then NBT, then simple material.

Permission-Gated Slots & Pages

Sell slots and pages to donor tiers, ranks, or level perks with infinibag.slots.N and infinibag.pages.N.
Per-page or total slot models, with optional cumulative permissions.

Optional Bag-as-Item

A configurable player-head item that lives in the hotbar and opens the bag on right-click.
Cannot be dropped, stored in chests, or lost on death. Locked-to-slot or movable modes.

Recovery Vault

If an admin lowers a player's perms and items land on locked pages, /bag recover opens a separate vault to take them back.
A join notification reminds players they have items waiting.

Developer API

An optional API lets other plugins read and write a player's bag at runtime, soft-depend friendly with no extra jar to install.
Mail systems, reward systems, and custom shops can deposit items straight into a player's bag, even while they're offline.
Offline-safe (UUID-keyed) and async-safe, with strict item grouping that matches full material plus NBT.

Networks & Extras

SQLite out of the box, MySQL for networks.
Bungee and Velocity cross-server bag sync with safe locking.
PlaceholderAPI support and an anvil-based search GUI.
Configurable open sound (volume, pitch, audible radius) and bundled en + fr locales, easy to add more.

Developer API

Other plugins can read and write a player's bag at runtime through the optional InfiniteBagAPI. No hard dependency and no extra jar, it ships inside the normal plugin jar and is safe to soft-depend on.

isEnabled(UUID) can the player use their bag
accepts(ItemStack) would the bag store this item type
contains(UUID, ItemStack) does the bag already hold this exact type
add(UUID, ItemStack) store an item, returns the amount that did not fit

Grab it with the static InfiniteBag.getApi() (null-checked, soft-depend safe). Works offline via UUID-keyed database access, is async-safe (per-UUID locked), and uses strict item grouping that matches full material plus NBT (name, enchants, damage, custom model data).
