About this project
What does Secret Blocks (multi-loader) add?
Secret Blocks adds blocks that take the look of the blocks around them. Use them to build hidden rooms, secret doors, traps and redstone that nobody can see.
- Place a secret block against a wall, and it looks like that wall.
- Underneath, it works like the block it stands in for: a door still opens, a chest still holds items, a repeater still repeats.
- Tools let you change a block's look face by face, or see through every disguise.
Every block and tool, with recipes and pictures, is in the wiki.
See through every disguise
The Builder's Goggles show the real block behind each disguise. On the left, a wall as anyone sees it; on the right, the same wall through the goggles: secret redstone, a repeater, a comparator, an observer, a daylight detector and a sculk sensor.
