Once again, the mechanisms are quite straightforward. In this guide, I will teach you how to create a hidden chest within a wall in Minecraft PE.
Let’s start with the wall itself; I’ve constructed a rough imitation of a wall inside a house:
We will build from the opposite side of the wall. Let’s begin with the pistons and the signal leading to them:
Now we connect the signal to them:
Next, place the chest and run redstone dust to the appropriate spot in the wall:
Install a lever and test it out:
Everything is functioning properly. However, I think the lever is too conspicuous. To address this, I added buttons as decoration on the wall, only one of which activates the mechanism:
In this case, the mechanism only activates for a brief moment, so you’ll need to be quick to open the chest.
