How to show an updating variable on scene_map

[Cruelty]

I actually asked this question many moons ago (on .net) but I kinda fell off with RMXP (when the ennglish version because the standard instead of PK).

I just need to know how I can add a plain-text variable visible on the top/center of the map scene? Thanks in advance. =D

Ok, unfortunately I can't figure out a simple way to do this.

1) First create a plane called @text in the script you're using (use a global if you want). @text = Plane.new
2) Create a new, empty bitmap called @textBMP. @textBMP = Bitmap.new(640,480)
3) Assign the bitmap to the plane. @text.bitmap = @textBMP4) Draw the text. @text.bitmap.drawtext(x, y, 240, 64, str)

[create the plane and bitmap in the definition part of the script, ie near the top]

@text = Plane.new
@textBMP = Bitmap.new(640,480)

...

@text.bitmap.drawtext(x,y,240,64,"")

Hm, in my opinion, a plane is to big for a simple variable-text. I would solve the problem as follows:

class Scene_Map
  VARIABLENNUMMER = 1 #Number of the variable
  alias variable_main main
  def main
    @variable_text = Show_Variable.new(VARIABLENNUMMER)
    variable_main
    @variable_text.dispose
  end
  alias variable_update update
  def update
    @variable_text.update
    variable_update
  end
end

class Show_Variable < Sprite
  #DEFAULT VALUES
  COLOR = [0, 0, 0] #White
  X = 20
  Y = 0
  #INITIALIZING
  def initialize(variable_id, x=X, y=Y, color=Color.new(*COLOR))
    super()
    @variable_id = variable_id
    self.bitmap = Bitmap.new(150, 50)
    self.x, self.y, self.z = x, y, 4999
  end
  #UPDATING/REFRESHIN
  def update
    bit = self.bitmap
    bit.clear
    bit.draw_text(0,0,bit.width, bit.height, $game_variables[@variable_id].to_s)
  end
end

I'd solve this by simply creating a new window which gets refreshed every frame... as everyone else posted a script in here, let me do the same...

#==============================================================================
# Scene_Map Variable Display
#------------------------------------------------------------------------------
# Script by BlueScope
#==============================================================================

class Scene_Map
  #--------------------------------------------------------------------------
  alias vardisplay_initialize initialize
  def initialize
    vardisplay_initialize
    @variable = "Test"
  end
  #--------------------------------------------------------------------------
  alias vardisplay_main main
  def main
    @vardisplay_window = Window_Base.new(0, 0, 640, 64)
    @vardisplay_window.opacity = 0
    @vardisplay_window.contents = Bitmap.new(@vardisplay_window.width - 32, 
      @vardisplay_window.height - 32)
    @vardisplay_window.contents.draw_text(0, 0, 600, 32, @variable, 1)
    vardisplay_main
    @varidosplay_window.dispose
  end
  #--------------------------------------------------------------------------
  alias vardisplay_update update
  def update
    @vardisplay_window.contents.clear
    @vardisplay_window.contents.draw_text(0, 0, 600, 32, @variable, 1)
    vardisplay_update
  end
  #--------------------------------------------------------------------------
end

I suggest you to adjust the naming on a couple of those variables (mainly @variable ^_^ ) to make things easier for you... other than that, that thing is ready to go.
