Build a bookshelf door that opens only when a book is on its last page.
A dusty library. One book on a stand. Read to the very last page and the bookshelves slide apart…
- New skill Reading a lectern with a comparator
- Level 6 · Inventor's Lab
- Difficulty Intermediate
- Mode Creative
- Time 45–60 min
- Ages 13+
What you’ll build
Build a dusty library with a bookshelf wall that hides a secret door. Write a mystery book, set it on a lectern and run a long trail of redstone so only the strongest signal gets through. Turn to the last page and the shelves slide apart.
Finish line: Your library's bookshelves slide apart only when someone turns the secret book to its very last page.
Bonus challenge: Try a chiseled bookshelf with a comparator reading it. Can you make sliding one particular book into the shelf open the door instead?
You’ll need
- Bookshelves
- Sticky pistons
- Book and Quill
- Lectern
- Comparator
- Redstone torch and dust
You choose
- My library's name
- The secret book's title
- What hides behind the shelves
Stuck?
- Door opens on early pages? Make the dust trail longer so weaker signals fade out first.
- Never opens? Shorten the trail by a block or two and test the last page again.
- The comparator must face away from the lectern, with its dust leading off from the front.
