Overview

Writes the current game screen. No idea why I didn’t just do all this stuff in the Engine class. Look how empty that thing is. You probably didn’t even see it up there.

Instance Method Details

#handle_stairs ⇒ Object

Another function that could be handed off to the Room class. Like that whale of a beast needs more methods. Maybe it would make more sense to move some functionality into the Engine class.

def handle_stairs
  Zarta::HUD.new(@dungeon)
  puts 'You see stairs leading down here.'
  return unless @prompt.yes?('Go down?')
  @dungeon.level += 1
  @dungeon.room = Zarta::Room.new(@dungeon)
  refresh
end

#next_rooms_prompt ⇒ Object

Not one to be left out, this guy could also piss off somewhere else. Seems like this class is doomed. When I can get round to it, that is. So maybe it will be ok…

def next_rooms_prompt
  next_rooms_options = []
  @dungeon.room.new_rooms
  @dungeon.room.next_rooms.each do |room|
    next_rooms_options << room.description
  end

  Zarta::HUD.new(@dungeon)
  puts 'You see these rooms ahead of you,'
  next_room_choice = @prompt.select('Choose one:', next_rooms_options)

  @dungeon.room.next_rooms.each do |room|
    return room if next_room_choice == room.description
  end
end

#refresh ⇒ Object

When the player moves into a new room, this function checks if anything has spawned in it and calls the appropriate functions. Looking at it now, it seems that all of this fucnctionality could be off-handed to the room class. I’m just creating HUD objects in any function where I need to refresh it anyway. Feels redundant.
