¶ Scene Watcher
Category: ⚙️ System
¶ Description
Outputs collision events from marbles hitting your real-room furniture in Mixed Reality (walls, floor, ceiling, windows, doors, desks). Tune the bounciness per surface group with the three dials.
Requires Mixed Reality / scene understanding to be active so Patchworld knows where your physical walls/floor/ceiling and furniture are. For each marble collision the block emits the hit position (X/Y), velocity, and which surface category was hit. Walls, windows, doors and desks also emit an index so you can tell which specific wall or piece of furniture was struck.

| Hit Y | Jolt Output | Vertical position (in local space) of the marble's impact point on the surface. |
| Velocity | Jolt Output | Magnitude of the marble's relative velocity at the moment of impact. Useful as a 'hit force' value for sound or visual feedback. |
| Is floor | Jolt Output | Fires 1 when a marble hits the floor. |
| Is ceiling | Jolt Output | Fires 1 when a marble hits the ceiling. |
