Getting Started
This page walks you through your first project. Each step is covered in more detail on the linked pages.
Craft it from two sticks and one emerald:
. . E E = Emerald
. S . S = Stick
S . .
The recipe is unlocked from the start and shows up in your recipe book without any precondition. In Creative the wand is in the Tools & Utilities tab, and operators can hand one out with /expandedbuilding give.
- Left-click a block with the wand → position 1. The block is not broken.
- Right-click a block with the wand → position 2.
The two clicks only define the footprint. Both clicked blocks belong to the site, plus a one-block margin on every side. Vertically the site always spans the full world height, so cellars and towers work without having to click the corners at the right altitude.
The outermost blocks of the site are marked on the ground, following the terrain. Whatever is marked belongs to the site, so you can read the border right under your feet.
Right after the second click:
- your inventory and game mode are saved to disk,
- you switch to planning mode (Creative),
- a Builder NPC appears at the site.
Now build whatever you like inside the site. You may also break anything inside it – levelling terrain and digging a cellar are part of planning. Everything outside the site stays protected. Doors, trapdoors and fence gates can be opened as usual. See Planning Mode.
Right-click the Builder to open the project dashboard and press Finish plan.
- The site is restored exactly to how it was before planning – cleared terrain is back until the build runs.
- Your original inventory and game mode are restored.
- Your design stays visible as a ghost blueprint: blue for blocks that will be placed, red for positions the builder will clear.
- The dashboard now shows the material list.
Either:
- press Hand in materials in the dashboard – the builder takes only what is still needed from your real inventory, or
- crouch + right-click a chest with the wand to make it the project's material chest. The builder takes what he needs from it, and a hopper can keep it topped up.
Every project also costs a few emeralds as the builder's wage. If the project has to clear terrain, a chest is on the material list as well – it becomes the builder's tool chest. See The Builder.
Once everything is delivered, the status changes to Ready to build. Press Start building.
The builder first clears the site from top to bottom (with tools from his tool chest), then builds – by default one block per second. The Speed button switches between 1x, 4x and 20x for a higher wage.
- Edit plan reopens planning at any stage, even in the middle of construction. Blocks that are already built are not charged again.
- Cancel ends the project and returns all delivered materials and emeralds.
