@deprecated Use PlacementInstantiator instead. This class is a backward-compatible alias. BuildingInstantiator was renamed to PlacementInstantiator in 5.1.0 to align with GridPlacement C# naming conventions. All functionality is identical — this class exists only to prevent breaking existing code. Migration: Replace BuildingInstantiator with PlacementInstantiator in your code. Deprecated in 6.0. The old name is scheduled for removal in a future release.
