Walk Through Your House Design —First-Person, In-Browser
Orbiting shows the house; walking shows it. Enter walk mode and the reticle becomes your pointer: WASD to move, Shift to run, the mouse to look, E to open the door in front of you. V steps you out to third person to watch yourself cross the room. Editing keeps working from inside — reposition a window while standing under it. Esc hands the keyboard back.
How it works — in the app
Move like you mean it
WASD to walk, Shift to run, mouse to look — pointer lock, the reticle is the pointer.
Open doors
Press E at a door and walk through it; press V to see yourself in third person.
Edit from inside
Move furniture while standing in the room — then Esc to come back out.
What you get
Walk through it is one of fifteen feature pages covering what ships in Builder today — every claim here maps to a shipped, verified feature. The list below is the concrete surface:
- First-person walk mode: WASD, Shift to run, mouse look with pointer lock
- The reticle is the pointer — aim, click, edit, all from inside the house
- E opens the door in front of you; editing works from inside the house
- V toggles third person — watch your avatar cross the room
- Co-editors see you: 21 distinct people, name over head, shirt colour from your account id
- Gait driven by observed motion — a peer on a bad connection walks slowly, never skates
FAQ
Can I move furniture while walking around?
Yes — editing works from inside the house. Stand where the sofa goes, aim with the reticle and place or move; placement legality still checks every move.
Will other people see me in the house?
If you are in a shared room, yes. Every presence in every view is one of 21 distinct character models with your name over its head and a shirt colour derived from your account id — the same colour on every screen.
What does my walk look like to others?
Honest. Gait is driven by observed motion rather than sliding transforms, so a co-editor on a poor connection walks slowly — and never skates across the floor at full speed.
