# Show Wielded Item [`show_wielded_item`]
This mod displays the name of the wielded item above the hotbar and
statbars.
This mod is compatible with the HUD Bars [`hudbars`] mod.
This mod *disables* itself if Unified Inventory is detected to show item names.
Compatibility with other HUD-related mods is possible, but not guaranteed.
Version: 1.2.1
## A note for Unified Inventory users
The mod Unified Inventory adds its own wielded item display (as of 16/08/2024).
So if you use that mod and have the item names features of that mod
enabled, then Unified Inventory takes precedence.
If the Unified Inventory mod was detected, and the setting
`unified_inventory_item_names` is set to `true`, then
`show_wielded_item` wont do anything and let Unified Inventory
display the wielded item instead. A message will appear in
the debug log if this happens.
## Credits
Released by Wuzzy.
The original mod code was taken from the file “`item_names.lua`
found in the Unified Inventory mod maintained by VanessaE. This code
has been later modified.
Original author: 4aiman
