ShulkerLayers

ShulkerLayers

A Fabric mod for Minecraft that lets you pack shulker boxes inside shulker boxes, with a configurable nesting depth.

What it does

Vanilla Minecraft blocks placing a shulker box into another shulker box. ShulkerLayers lifts that restriction in a controlled way: every shulker box gets a hidden layer value, and a higher-layer box can hold lower-layer boxes inside it. This lets you build compact, organized storage without spiraling into infinite recursion.

How it works

- Tooltip. Every shulker box has an integer `layer` (0 by default). A regular crafted/looted shulker box is layer 0. - Tooltip. Surround any shulker box with shulker shells in a `+` pattern (same as the original shulker box recipe) to bump its layer up by 1. The output keeps the input box's color, contents, and custom name. - Tooltip. A box may be placed inside another shulker box only if the inner box's layer is *lower* than the outer box's layer. So a layer-0 box fits into a layer-1 box; a layer-1 box fits into a layer-2 box; and so on. Boxes of equal or higher layer are rejected. This guarantees you can never nest infinitely. - Tooltip. A box with layer ≥ 1 shows its layer in its tooltip.

The upgrade recipe (where `S` = shulker shell, `B` = any shulker box):

``` S S B S S ```

Configuration

A config file is created at `<game>/config/shulkerlayers.json` on first launch:

```json { "maxDepth": 3 } ```

| Key | Type | Default | Range | Description | | ---------- | ---- | ------- | ------ | ------------------------------------------------------------------------------------ | | `maxDepth` | int | `3` | 0 – 64 | Highest layer a shulker box can be upgraded to. `0` effectively disables the recipe. |

Mod Menu support is planned for the 26.2 release.
