I want to show my mechanical house in minecraft version 1.12
I'm a Russian redstoner so I sorry for my bad English.
On the last versions of minecraft, the functionality of the command blocks was greatly improved and in this house I tried to show what the command blocks are capable of. Almost all mechanisms are based on them, and more than 600 command blocks are used in this house.
More about the mechanical house, the location of all the secret rooms, a combination of locks, as well as a demonstration of all the mechanisms in the house, see in the video:
P.S. Video in russian but there are English subtitles
