Map name when you change it (for 3 second)

[WiZ`]

i've make a little script that allow you to call the map name when you change it... like in Kingdom Hearts 2 (it show you the mapname for 3 or 4 second)

class Game_Map
  def name
    $map_infos[@map_id]
  end
end

class Window_MapName2 < Window_Base
  #--------------------------------------------------------------------------
  # - Inizializzazione dell'oggetto
  #--------------------------------------------------------------------------
  def initialize
    super(0, 0, 640, 200)
    self.contents = Bitmap.new(width - 32, height - 32)
    refresh
  end
  #--------------------------------------------------------------------------
  # - Aggiornamento
  #--------------------------------------------------------------------------
  def refresh
    self.contents.clear
    self.contents.font.name = "Bimini"
    self.contents.font.size = 40
    self.contents.font.color = normal_color
    self.contents.draw_text(64, 6, 480, 136, $game_map.name, 1)
  end
end

this is a new class (really simple)

class Interpreter
  #--------------------------------------------------------------------------
  # - Trasporto
  #--------------------------------------------------------------------------
  def command_201
    if $game_temp.in_battle
      return true
    end
    if $game_temp.player_transferring or
       $game_temp.message_window_showing or
       $game_temp.transition_processing
      return false
    end
    $game_temp.player_transferring = true
    if @parameters[0] == 0
      $game_temp.player_new_map_id = @parameters[1]
      $game_temp.player_new_x = @parameters[2]
      $game_temp.player_new_y = @parameters[3]
      $game_temp.player_new_direction = @parameters[4]
      @mapname = Window_MapName2.new
      @mapname.x = 0
      @mapname.y = 100
      @mapname.opacity = 0
    else
      $game_temp.player_new_map_id = $game_variables[@parameters[1]]
      $game_temp.player_new_x = $game_variables[@parameters[2]]
      $game_temp.player_new_y = $game_variables[@parameters[3]]
      $game_temp.player_new_direction = @parameters[4]
    end
    @index += 1
    if @parameters[5] == 0
      Graphics.freeze
      $game_temp.transition_processing = true
      $game_temp.transition_name = ""
    end
    return false
  end

This is what i've edit... is the interpreter class (interpreter5 in the script list) and i've try to put in some short line whit the ones i can call the map name when i teleport... the problem is that this script show me the name of the wrong map and the window doesn't disappear after few second... how can i do it? pls help me X|
