How to Build a Working PC and Healer Station
Placing the Core Blocks
Craft a Black PC or Blue PC and place it against a wall in your base. Place a Black Healer or Blue Healer on the floor nearby — it needs open space on all sides so you can walk into it. Both blocks come in Black and Blue variants; pick whichever matches your build, since the color only changes appearance.
Using the PC
Right-click the PC to open your storage interface. Deposit and withdraw Pokémon here. Keep the PC within a few blocks of your Healer so you can swap your team and heal in one trip.
Using the Healer
Step into the Healer and right-click it. Your party is restored. If the Healer does nothing, check that no block is sitting directly on top of it and that you are standing inside its hitbox, not beside it.
Supporting Furniture
Surround the station with Black Chair or Blue Chair blocks for seating, a Black Clock or Blue Clock for decoration, and a Black Rug or Blue Rug on the floor. Add a Black Trade Machine or Blue Trade Machine next to the PC if you plan to trade with other players. A Black Vending Machine or Blue Vending Machine placed alongside completes the room. Keep at least one empty block between each machine so you can reach every interaction face.
