Function: detectFloorTransitions()

detectFloorTransitions(route, graph): FloorTransition[]

Defined in: packages/wayfinding/src/transitions.ts:40

Detect floor transitions in a route by comparing consecutive leg levelIds.

For each pair of adjacent legs where the floor changes:

• The transition coordinate is the last point of the departing leg.
• The category is read from the departing leg's own floorChange.via instruction when present (grid engine); otherwise it falls back to the nearest graph node within VERTICAL_NODE_SEARCH_RADIUS_M of the transition coordinate (legacy engine, whose leg endpoint IS the node coordinate).
• If neither source resolves a category, it defaults to 'elevator'.

Parameters

Returns
