Detailed Description

Abstract base class for entity interaction handlers.

Each entity type (object, door, sprite, item) has its own handler that implements this interface. This provides consistent interaction patterns while allowing specialized behavior.

The InteractionCoordinator manages mode switching and dispatches calls to the appropriate handler.

SetContext()

void yaze::editor::BaseEntityHandler::SetContext ( InteractionContext * ctx )

inline

Set the interaction context.

Must be called before using any other methods. The context provides access to canvas, room data, and callbacks.
