Item Restrictions

BackpacksPlus allows for two levels of item restriction:

1. Global Shulker Box Prevention:

   • Controlled by the backpacks.prevent_shulker_boxes setting in config.yml.

   • If true (default), no shulker boxes can be placed in any BackpacksPlus backpack, regardless of individual backpack definitions.

2. Per-Backpack allowed-items List:

   • Defined in your backpacks/*.yml files for each backpack type using the allowed-items key.

   • If this list is present and contains item IDs, only those items can be placed in that specific backpack type.

   • If the list is empty (allowed-items: []) or the key is missing, all items are allowed (except shulker boxes if globally prevented).

Players will receive a message if they attempt to place a restricted item into a backpack.
