Trapped Chest, in one place: what it is and what it does

A chest that outputs a redstone signal proportional to the number of players viewing it. Signal strength equals the number of players with the chest open, up to 15.

As a trigger it watches the world for an event and converts that event into a redstone signal. It is a chest that doubles as a player sensor, perfect for loot traps and secret-room triggers.

Since 1.5 the Trapped Chest has been part of redstone, and Java Edition 26.2 is the version described here.

Inside the Trapped Chest: what the signal actually does

Input for the Trapped Chest means players opening the chest, and the output is signal strength = number of players viewing.

Its output equals the number of players currently viewing it, so one player gives signal 1 and the signal scales up with viewers to a cap of 15. It looks almost identical to a normal chest apart from a faint red tint on the latch. The signal lasts only while the chest GUI is open.

It acts instantly with no redstone-tick delay of its own, so it adds nothing to the timing of a circuit.

Strength 15 at the source means the last powered piece of dust sits 15 blocks away from the Trapped Chest, and the one after it stays dark.

These are the modes you can put the Trapped Chest into, and each one changes what comes out: analog signal based on viewer count.

Placing the Trapped Chest, step by step

1. 1Craft the Trapped Chest: 1 Chest + 1 Tripwire Hook → 1 Trapped Chest.
2. 2Set the Trapped Chest down facing the way the signal has to travel, on a block that will actually hold it in place, somewhere the event you care about happens in range.
3. 3Lead the signal it produces into a repeater or dust line so the rest of your contraption can respond to the detected event.
4. 4Before it goes anywhere near a real build, run the Trapped Chest on its own a few times over and check every result against the timing figures listed above this step.

Where the Trapped Chest earns its keep

• ▸Player traps
• ▸Secret room triggers
• ▸Player counting
• ▸Security systems

Tips & common mistakes

• !Looks similar to regular chest (slight red tint)
• !Can be placed next to regular chests
• !Signal only while chest is open
• !Because the signal is just 1 for a single player, drive a comparator or repeater off it rather than expecting a strong 15.
