ItemLocks

by Kirdow

With ItemLocks, a player can lock individual inventory slots so that items in them cannot be moved by accident during a fight or while carrying gear.

FabricForgeNeoForgeClient-side onlyAll rights reserved1.18.2 – 26.3

What it does

ItemLocks lets a player lock single inventory slots. Holding the LOCK key (default C) while left clicking a slot toggles its lock. A locked slot resists moves, drops and other accidental changes, so a weapon or armor piece stays where it was placed. Holding the BYPASS key (default B) and interacting with a slot skips the lock for that action, and emptying a slot this way does not remove its lock. Empty slots cannot be locked yet, and a lock on an empty slot clears once an item is placed there.

Lock states are stored separately for each world and server, so the setup carries over without any manual saving. The settings screen opens from the mod list or with the OPTIONS key (default N), and every option can be adjusted there. Cloth Config API is required, and Mod Menu and Mouse Tweaks are optional. The mod runs on the client only and is published for Fabric, Forge and NeoForge across 28 release versions, 1.18.2 – 26.3. All rights reserved applies to the code, so the mod is not open source.

Key features

  1. Per-slot locks

    Any inventory slot can be locked or released with a click while the LOCK key is held.

  2. Bypass key

    Holding the BYPASS key lets a player move a locked item when it is needed, without removing the lock.

  3. Saved per world or server

    Lock layouts are kept for each world and server and reapplied automatically on return.

  4. Configurable settings

    Options are reachable from the mod list or the OPTIONS key and cover the key layout and lock behavior.

  5. Lock clears on empty slots

    An empty slot with a lock releases itself until an item is placed in it again.

Questions

No. Only the player's game needs it, and servers run without it.

Which loader should be used with ItemLocks?

The mod is published for Fabric, Forge and NeoForge. The latest Fabric and NeoForge files target 26.3, while the latest Forge file targets 1.20.4.

Can the lock be bypassed when an item is needed?

Yes. Holding the BYPASS key, default B, lets a locked slot be used without removing its lock.
