Carpet Shadow

carpet extension to fix various bugs related to shadow item stacks

Carpet Settings

• shadowItemMode what should happen to shadow items when saved and re-loaded from disk?

  • UNLINK ( vanilla default = dupe them )
  • PERSIST ( shadow items will re-link once re-load )
  • VANISH ( shadow items will disappear when re-load )

• shadowItemTooltip

  shows the shadow stack unique identifier when hovering over a shadow stack with the mouse

• shadowItemFragilityFixes

  various fixes to item related actions that might unlink/dupe/delete the shadow stacks

• shadowItemUpdateFix

  inventory updates from shadow items will propagate to the other shadow item stacks even if in other invenotories

• shadowItemPreventCombine

  by default instances of the same shadow stack won't merge on inventory actions; this option expands that behavior and prevents merging operations between any shadow stack

  PS: this option only has an effect if shadowItemFragilityFixes is active

• shadowItemIdSize

  changes the length of the shadow stack unique identifiers

  PS: do not edit unless you know what you're doing

Known Bugs

• General
  • MINOR: this mod only tracks shadow items that get generated with update suppression and the item swap operation, if another method of generating a shadow item is found this mod will not work.
• Persistence
  • MINOR: when the mod generates a new shadow ID it only performs a check on the currently loaded IDs so there is a very small chance of overlapping IDs
  • MINOR: if two instances of a shadow item get unloaded with different amounts, the stack count will be of the first instance to get loaded back
• Fragility
  • MAJOR: opening creative inventory will unlink and duplicate all the shadow stacks in the current inventory
• Tooltips
  • MINOR: on servers the tooltips are sent to the clients as LORE nbt tags; this mod will strip them down on the clientside but non modded clients will see some de-synced lores while performing item movements/splits in inventories
  • MAJOR (Unconfirmed): non modded creative inventory might behave strangely if tooltips are active on server
