PlayerInteractUseCase

scalata.application.usecases.playerusecases.PlayerInteractUseCase
class PlayerInteractUseCase extends CreatureUseCase[GameResult[GameSession], Direction]

Handles the “interact” command (pick up / open / read whatever lies on the tile immediately in front of the player).

==== Flow ====

  • Compute the target coordinate by adding direction.vector to the player’s current position.
  • If an item is present, delegate to its interact(GameSession) method and propagate the result.
  • If the tile is empty, return GameResult.error(GameError.ItemNotPresent).

The method is pure: all updates are returned in a new GameSession; no in-place mutation occurs.
