Write a trap manual in a book, and make a secret page open a hidden door.
Every great inventor keeps a secret book. Yours has one page that, when turned, opens a hidden door.
- New skill Lectern and comparator page lock
- Level 6 · Inventor's Lab
- Difficulty Intermediate
- Mode Creative
- Time 45–60 min
- Ages 13+
What you’ll build
Write a trap manual in a book, one trap per page, with how it works and how to reset it. Put it on a lectern with a comparator, then tune a dust line to a hidden door so only your secret page, or later, opens it.
Finish line: Your signed trap manual sits on a lectern, and turning to the secret page opens a hidden door.
Bonus challenge: Add a decoy: a second lectern with a fake book where the 'secret' page sets off your siren instead. Who falls for it?
You’ll need
- Book and Quill
- Lectern
- Comparator
- Redstone dust
- A hidden piston door
You choose
- My book's secret title
- The trap that gets the star page
- The secret page number
Stuck?
- Opens too early? Add dust so the weaker pages fade before the door.
- Never opens? Remove a block of dust and test your secret page again.
- The book needs exactly 15 pages for the signal to roughly match the page number.
