Unslab

by Dooji

Unslab turns modded slabs from other mods back into full blocks through a crafting recipe, for players who want their slab-based builds to become whole blocks again.

FabricServer required, client optionalGNU General Public License v3.0 onlyOpen source1.20.1 – 1.21.5

What it does

Unslab converts modded slabs back into full blocks using crafting. A GUI screen lets the player customize the mappings that decide which slab maps to which block. The server is required to run it, while the client may add it as an optional extra, and it does not work on servers without the mod installed. Fabric API and Omnilib are required. The mod is published for Fabric on 1.20.1, 1.21, 1.21.1, 1.21.2, 1.21.3, 1.21.4 and 1.21.5, under the GNU General Public License v3.0 only, and its source code is open.

Key features

  1. Slab-to-block crafting

    Modded slabs can be crafted back into full blocks, so a set of slabs from another mod can be recombined.

  2. Mapping GUI

    A screen in the game lets the player customize the mappings that link each slab to its block.

  3. Server-side operation

    The server runs the conversion, so the client may add the mod for extra features while the server needs it.
