Secret Blocks (multi-loader)

by Caliber Games

With Secret Blocks, a player can hide a block behind a copy that looks like the wall around it, for rooms, secret doors and traps built into ordinary builds.

What it does

Each secret block takes the look of a neighboring block, so a secret block set against a wall reads as that wall. Underneath, it still behaves like the block it stands for: a secret door opens, a secret chest holds items, and a secret repeater keeps repeating. Builders use this for hidden rooms, concealed redstone and traps that a visitor does not see until triggered.

The set includes disguised building parts, doors and trapdoors, buttons, levers and pressure plates in several variants. Redstone parts include Secret Redstone Dust, Secret Repeater, Secret Comparator and sensor blocks. A tool changes which face a block shows, and Builder's Goggles reveal the real block behind a disguise. Most secret blocks are crafted from their vanilla counterpart, and the wiki lists recipes with pictures.

Secret Blocks is open source under the GNU Lesser General Public License v3.0 only, with public source code, an issue tracker and a wiki. It is published for Fabric, Forge, NeoForge and Quilt, with files for 1.18 – 1.20.1 and Fabric API required on Fabric. Every player and the server need a copy of the mod.

Key features

  1. Disguised building blocks

    Several disguised building parts look like the surrounding wall or floor while keeping their function.

  2. Secret doors and trapdoors

    Secret Door, Secret Iron Door, Secret Trapdoor and Secret Iron Trapdoor work as their vanilla versions while hiding their shape.

  3. Hidden redstone

    Secret Redstone Dust, Repeater, Comparator and several sensor blocks carry circuits out of sight.

  4. Builder's Goggles

    Goggles show the real block behind a disguise, while anyone without them sees only the wall.
