Class PreviewBuilder

Namespace
GridPlacement.GDScript
Assembly
MoonBark.GridPlacement.GDScript.dll

PreviewBuilder\n\nPurpose Manages the visual preview instance used during building placement. The class requires the core runtime objects up-front: PlacementSettings, the GridTargetingState, PlacementState, and a GBLogger. These are accepted in the constructor so the caller is explicit about required dependencies.\n\nIn addition, resolve_gb_dependencies(container) exists to refresh or update dependencies from a PlacementContainer if the container changes during runtime (rare for tests but supported). The GridTargetingState is treated as the single source of truth for the positioner — the preview will always query the latest positioner when creating the preview.
