item reject
by MrAkula
Item Reject, a NeoForge utility for 1.21.1, lets players block unwanted items from entering the inventory during mining trips and other long sessions.
What it does
Item Reject gives control over which items the inventory accepts. A blacklist filter, edited from a clean GUI on the default key B, lists items to refuse, and a single click adds or removes an entry. The GUI includes a search bar that matches names and IDs, along with category tabs for sorting.
Pickup is cancelled outright rather than letting items drop back out. An item the filter rejects stays on the ground and never enters the inventory. A dedicated consumables tab also displays nutrition details for food items, including hunger points and saturation values. The blacklist is saved in a simple JSON file, so filters can be shared between modpacks or edited outside the game.
Item Reject is client-side only, so servers do not need it, and only the player's client has to run it. It requires Kotlin for Forge. The mod is published for NeoForge only, with version 0.0.5-a for 1.21.1 as the latest file, released under All rights reserved, so it is not open source.
Key features
Blacklist filter
Items added to the blacklist are refused at pickup, so unwanted stacks never reach the inventory.
Hard pickup prevention
The pickup event is cancelled, so a rejected item stays on the ground instead of being dropped back out.
Searchable GUI
A search bar matches item names and IDs, and category tabs organize the list, opened with the default key B.
Food nutrition tab
A consumables tab shows hunger points and saturation values for food items.
