The battlefield quality of a room-scanned match starts before the app opens. AR tracking works by watching your room through the camera, and a few minutes of preparation is the difference between a rock-solid miniature world and one that needs coaxing.

Light the room

Tracking quality is mostly a lighting story. The camera needs to see surface detail to hold the world in place.

  • Bright, even light is best. Turn on the room lights; open the curtains if it’s daytime.
  • Avoid strong backlighting — a window as the only light source turns the rest of the room into silhouettes.
  • Very dim or single-lamp rooms will track noticeably worse, especially during movement.

Give the battlefield a floor

The game builds your world on visible floor, and it fits your chosen battlefield size to the space you actually have.

  • More visible floor = more room for the world. You don’t need an empty room — the game is built to fit real spaces — but pushing chairs in and clearing stray objects helps.
  • Textured floors track better than featureless ones. Rugs, wood grain, and tile patterns give the camera detail to lock onto. A vast, perfectly uniform surface offers less to grip.
  • Reflective and glass surfaces confuse depth. If your space allows, favor scanning across matte surfaces.

Move like a camera operator

During the boundary walk and during play:

  • Steady, deliberate movement produces clean tracking. Whip-pans and sudden direction changes are the most common cause of drift.
  • Keep the phone pointed where you’re working. The game follows your aim; sweeping the camera across the ceiling mid-scan adds noise.
  • If tracking stumbles, slow down and let the camera see a detailed, well-lit part of the room for a moment. Recovery is normally quick.

Manage the phone itself

AR is one of the most demanding things a phone does. For longer sessions:

  • Start with reasonable battery or play near a charger; AR sessions use meaningfully more power than typical apps.
  • Warm phones throttle. If a long battle is planned, a case-free phone in a cool room performs better.
  • Close heavyweight background apps if your device is older — memory pressure affects stability.

Respect the space

A short version of the full safety guidance, which is worth one real read:

  • Know where furniture, stairs, pets, and other people are before you start.
  • The game plays on your floor — you’ll look down and move around, so keep the walkway clear.
  • Take breaks. Immersive play is more physical than it feels.

When the room fights back

Unusual spaces — L-shaped rooms, narrow layouts, cluttered corners — are supported, and the boundary tools let you adjust the play area the scan produced. If the battlefield lands somewhere odd or tracking keeps slipping, the AR & camera troubleshooting section walks through the common causes in order of likelihood.

One preparation pass is usually all it takes. After that, the room is a battlefield every time you open the app.
