Inve tory

by 1Foxy2

Inve tory limits inventory slots to what a player wears, so storage grows only as the armor and gear equipped increase.

NeoForgeClient and serverMIT LicenseOpen source1.21.1

What it does

Inventory slots stay locked until the player equips suitable armor, and the more costly the armor, the more slots it adds. Gear such as an Elytra can also grant slots. Slots are opened by hand from the inventory screen, and players can switch to automatic opening, which fills them in a chosen order: left to right from the top row, right to left from the bottom row, top to bottom from the left column, or in reverse. Items that have no armor attribute are ignored by default, but custom values can be added for items through datapacks.

The mod is aimed at hardcore-style survival, where storage is earned through gear instead of being available from the start. It is compatible with Curios slots, so accessory slots from that mod can sit alongside the inventory slots. It is published for NeoForge only, on version 1.21.1, and it runs on client and server, so the server and every player need it.

Key features

  1. Armor-locked slots

    Inventory slots remain closed until armor is worn, and heavier armor adds more of them.

  2. Gear-based slots

    Equipping an Elytra or similar gear adds slots, and removing it closes them again.

  3. Manual or automatic opening

    Slots can be opened by hand inside the inventory screen, or opened automatically in a set fill order.

  4. Custom item values

    Datapacks can assign slot values to items that carry no armor attribute.

Use cases

Hardcore survival runs

Storage grows only as the player gears up, so early game inventory stays small on purpose.

Curios accessory setups

Players who use Curios can keep accessory slots and armor-based inventory slots in the same run.

Who it’s for: Players on NeoForge 1.21.1 who want inventory space tied to equipment, and server owners who want the same rule for every player on a server.

What the author says

Your inventory is locked! To unlock slots, you need to wear armor-the more expensive it is, the more slots you get. its also possible to add a custom value to item using datapacks, in this case the armor attribute will be ignored.
