BackpackMC
Simple, safe, and flexible personal backpacks for your server by Brandon10x15

Want full docs, API details, and examples? GitHub Repository + README

Overview
BackpackMC gives each player a personal, persistent backpack they can open via command or a configurable shortcut item. Sizes are permission‑based (up to 6 rows). It includes auto‑pickup, sorting, previews, crafting refill, world/gamemode restrictions, multi‑backend storage, and a small API/events layer.

At a glance

API: Paper 1.21
Java: 21
Core features: shortcut item (BUNDLE by default), dynamic preview bar, auto‑pickup, auto‑sort (OFF/LIGHT/AGGRESSIVE), crafting refill after craft, clean/sort commands, world/gamemode restrictions
Storage: YAML, SQLite, MySQL + built‑in migration
Safety: cancels dupe‑prone interactions; sanitizes stacks on snapshot/save; removes shortcut items from backpack contents
Localization: en_US, de_DE with auto‑merge of defaults
Updater: GitHub‑based with optional auto‑download to the server update folder

General Use

For Players

Open your backpack: /backpack or right‑click the shortcut item
Send items quickly: drag/click items onto the shortcut in your inventory; get action bar feedback
Auto‑pickup: when enabled and you have permission, overflow or similar items route into your backpack
Keep it tidy:
- /backpack sort
- /backpack autosort <off|light|aggressive>
- /backpack sortinv — sort your inventory
- /backpack autosortinv <off|light|aggressive>
- /backpack sortchest — sort the currently open chest/barrel/shulker
- /backpack autosortchest <off|light|aggressive>

For Admins

Grant access: backpackmc.backpack.use
Set size: backpackmc.backpack.size.N (1–6); highest N applies
Choose restrictions: blacklist worlds or gamemodes; provide bypass nodes as needed
Pick storage: YAML/SQLite/MySQL; migrate anytime with /backpack migrate <YAML|SQLITE|MYSQL>
Maintain:
- /backpack clean
- /backpack reload
- Updater: enable in config; /backpack update and /backpack update download

Quick Commands

/backpack <player> — view others (requires backpackmc.backpack.others; edit requires backpackmc.backpack.others.edit)

Permissions (essentials)

Use & Size

Use: backpackmc.backpack.use
Size: backpackmc.backpack.size.1 … .6 (highest granted decides rows; default 1 row when use is present)

QoL

backpackmc.backpack.fullpickup — auto‑pickup routes to backpack

Notes & Safety

The shortcut item is unique per player; duplicates are cleaned up automatically. Dropping can be disabled via config.
Dupe‑prone actions in the backpack GUI (collect‑to‑cursor, double/middle click, certain drags/number‑key moves) are cancelled.
Crafting is duplication‑safe: the plugin refills consumed ingredients from your backpack after each craft with a per‑player lock.
On death, if not keeping: optional config can drop backpack contents before clearing.
Updater can auto‑download into the server’s update folder; apply on next restart.
