Trapped Chest — Minecraft block

Trapped Chest

Trapped Chest looks like storage but emits redstone power while a player has it open.

Description

Trapped Chest is crafted by combining a normal chest with a tripwire hook, producing one redstone-aware container. It stores items exactly like a regular chest and can form a large double version when placed beside another compatible block. The visual difference is subtle: a faint red band around the latch, easy to miss in a busy storage room.

When a player opens it, the block emits redstone power proportional to the number of viewers, up to signal strength fifteen. That signal can trigger lamps, pistons, droppers, TNT traps, alarm bells, or hidden doors. Because the inventory behaviour is otherwise normal, it fits naturally into bases as both utility and misdirection. Builders also use it in puzzle rooms where opening the correct container changes the surrounding mechanism.

How to use a Trapped Chest in Minecraft

  1. 1

    Craft the trapped chest

    Combine one chest with one tripwire hook in the crafting grid to get a single trapped chest.

  2. 2

    Place it where you need detection

    Set the chest down on a solid block; the red latch marks it as the redstone-aware version.

  3. 3

    Wire the redstone output

    Run redstone dust, a comparator, or a repeater from the block to the device you want to trigger.

  4. 4

    Connect a trap or alarm

    Link the line to TNT, a dropper, a piston door, a note block, or a redstone lamp.

  5. 5

    Test by opening it

    Open the chest yourself; the signal stays on while at least one player is viewing the inventory.

Important

Two trapped chests placed side by side form a large double chest, but a trapped chest will never merge with a normal chest.
