      public InteractionDetector(float range)
      Constructs an InteractionDetector with the specified interaction range.
      Parameters:
      range - The interaction range within which entities are detected.

    • InteractionDetector

      public InteractionDetector(float range, List<EntityType> interactableEntities)
      Constructs an InteractionDetector with the specified interaction range.
      Parameters:
      range - The interaction range within which entities are detected.
