Class ManipulationTransformCalculator

Namespace

GridPlacement.GDScript

Assembly

MoonBark.GridPlacement.GDScript.dll

ManipulationTransformCalculator - Pure logic component for manipulation transform calculations.\n\nResponsibilities: - Calculate final transforms for placed objects after manipulation - Preserve flip semantics (negative scale values) during transform application - Provide testable, isolated transform logic separate from system dependencies\n\nThis component contains NO dependencies on: - Scene tree - Signals - State management - Input handling\n\nAll methods are pure functions that take inputs and return outputs.
