BackPack Plugin

BackPack Plugin
Overview
The Backpack plugin gives players there own personal portable storage in Minecraft. U can open it just like a chest and it saves ur stuff even when the server restarts. Every backpack is unique and linked to the owner. U cant put a backpack inside another backpack to prevent exploits. Everything is super customizable.
Also has comands to give, view and manage the backpacks and full config support.
Features:

• Backpack Items

• Players can get them via comand (/backpack give) or craft them.

• Every backpack is linked to a UUID and player name.

• The lore on the item shows: Owner name, Backpack number, How full it is (used slots / total slots), and "Right click to open".

• Comands
  /backpack give [rows] [item]
  Gives a backpack to someone.

  Optional:
  rows: size of it (like 2x9, 3x9)
  item: what item the backpack should be (e.g. CHEST, SHULKER_BOX)
  /backpack seeinside
  Lets u look into the backpack of another player using his backpack number.

/backpack reload or /bp reload
Reloads the config (items, recipes, lang stuff) without restarting the whole server.

• Crafting
• Has a default recipe but u can completely change it in the config (shape, materials etc).
• U can set it to craft a real working backpack or just a dummy item.
• Inventory Stuff
• When u open it, u can move everything except the backpack u are currently looking inside.
• U can move other backpacks around but u cant put them inside the open one.
• The item lore updates automaticly when u put stuff in or take it out.
• Saving / Persistence
• All backpacks get saved to backpacks.yml (Contents, Size, Owner, Display name).
• Loads automaticly when the plugin starts.
• Config Options
• Change the item for the backpack
• Set default and max rows (size limits)
• Full crafting recipe config
• Language support (English & German msgs)
• The config has english comments so u know what everything does.
• Compatibility
• Works with Paper/Spigot 1.21+
• Needs Java 17 or newer
• Works across servers and offline players cause it uses UUIDs.
• Dev Notes
• Uses PersistentDataContainer to link the items to the inventorys.
• Has a custom BackpackInventoryHolder so the plugin knows which inv belongs to which item.
• Made it so it prevents server errors from nesting backpacks or loosing items.
