Inventory Shuffle

A client-side Fabric mod that scrambles the layout of every container and inventory screen the instant it opens. Open a chest, your inventory, a furnace, a villager trade window - and the slots, the background panel, and the buttons all jump to fresh random positions. Your clicks still land: the mod moves the real slot coordinates that vanilla uses for hit-testing, so hovering and clicking follow the slots wherever they end up.

What it does

On every container/inventory screen open, it displaces every slot by an independent random offset, the background panel origin, and every button / clickable widget.
Each element is clamped to stay on screen, so nothing scrolls off where you cannot reach it.
Re-shuffles on window resize, always offsetting from the original vanilla layout (offsets do not compound).
Purely client-side and purely cosmetic-layout: no gameplay data changes, no server component.

Loader and version

Loader: Fabric
Minecraft: 1.21.x - this jar is built with official Mojang mappings against 1.21.11 and declares minecraft >=1.21.1.
Requires: Fabric Loader >= 0.19.2, Fabric API, Java 21+
Environment: client only (will not load on a dedicated server)

Compatibility note

A single Fabric jar is version-specific: the mod mixes into the client GUI API (AbstractContainerScreen#init, the Slot.x/Slot.y fields via AccessWidener, and AbstractWidget setX/setY), and those click/hover methods and slot fields change between versions. The >=1.21.1 declaration is permissive but only verified on 1.21.11 - other Minecraft versions may need their own per-version Fabric build rather than this one jar.

Config

A file config/inventoryshuffle.properties is written on first launch:

Key	Default	Meaning
`enabled`	`true`	Master on/off switch.
`maxOffset`	`12`	Max displacement magnitude in GUI pixels (0-80).
`shufflePanel`	`true`	Also move the background panel origin.
`shuffleButtons`	`true`	Also move clickable widgets (buttons).

Set maxOffset=0 (or enabled=false) to effectively disable the shuffle.

Install

Drop InventoryShuffle-1.0.0.jar into your client's mods/ folder alongside Fabric Loader and Fabric API.
