This is the room every SandboxVille building starts in. It shows a kiosk with instructions for connecting your AI, and a big STOP button that freezes the whole building at once. It gives your AI nothing to work with; it's just where it arrives and checks in.
The Lobby. Our own screenshot, not concept art. The downloadable copy of this room is the sign and the kiosk logic; the walk-through view above is the live building.
Get lobby.zip below. Unzip it, you'll get a lobby/ folder with one file inside, room.json.
Copy the lobby/ folder into the rooms/ folder of your SandboxVille code, so the path reads rooms/lobby/room.json.
Run the command on the right. It prints the door sign, plain text, so you can see exactly what this room is and is not allowed to touch.
You'll need first: Node.js 22+ and a copy of the SandboxVille code (the folder that has rooms/, tools/, and harness/ in it).
