RPGMXP - Issue with variables (that most likely can be solved using scripts)

[DerVVulfman]

Read it. It's a bit RM2K / 2K3 old school. Not saying an event system doesn't come in handy, as I've seen a few good ones. But your request may be easier to solve as a script.

May I ask what's the purpose of the 4-digit display?

in any event, here's a cheap script I penned in 2 minutes. More time typing instructions.

cheapo window

Code:

# The window position (x and y)
  FOUR_DIGIT_X = 0
  FOUR_DIGIT_Y = 0


#==============================================================================
# ** Window_FourDigit
#------------------------------------------------------------------------------
#  This message window is used to display digits.
#==============================================================================

class Window_FourDigit < Window_Base
  #--------------------------------------------------------------------------
  # * Object Initialization
  #--------------------------------------------------------------------------
  def initialize
    super(FOUR_DIGIT_X, FOUR_DIGIT_Y, 96, 64)
    self.contents = Bitmap.new(width - 32, height - 32)
    self.visible = false
  end
  #--------------------------------------------------------------------------
  # * Set digit
  #--------------------------------------------------------------------------
  def set_digit(digit)
    if digit == nil
      self.visible = false
      return
    end
    # If at least one part of text and alignment differ from last time
    if digit != @digit
      # Redraw text
      self.contents.clear
      self.contents.font.color = normal_color
      self.contents.draw_text(0, 0, self.width - 32, 32, digit.to_s)
      @digit = digit
    end
    self.visible = true
  end  
  #--------------------------------------------------------------------------
  # * Dispose
  #--------------------------------------------------------------------------
  def dispose
    super
  end
end



#==============================================================================
# ** Scene_Map
#------------------------------------------------------------------------------
#  This class performs map screen processing.
#==============================================================================

class Scene_Map
  #--------------------------------------------------------------------------
  # * Public Instance Variables
  #--------------------------------------------------------------------------
  attr_accessor :four_window              # The window variable
  #--------------------------------------------------------------------------
  # * Main Processing
  #--------------------------------------------------------------------------
  alias four_main main
  def main
    # Make sprite set
    @four_window = Window_FourDigit.new
    four_main
    @four_window.dispose
  end
end



#==============================================================================
# ** Interpreter
#------------------------------------------------------------------------------
#  This interpreter runs event commands. This class is used within the
#  Game_System class and the Game_Event class.
#==============================================================================

class Interpreter
  #--------------------------------------------------------------------------
  # * Set the digit
  #     digit : The digit value, or nil if you want to hide the window
  #--------------------------------------------------------------------------
  def set_digit(digit)
    if $scene.is_a?(Scene_Map)
      $scene.four_window.set_digit(digit)
    end
  end
end

You can use a simple script call in a map event window. The script call is 'set_digit' that contains either a digit value or nil. nil hides the window.

For example, using @>Script: set_digit(22) would turn the window on and display 22 in the window. And a later call of @>Script: set_digit(6352) would change it to exactly that. Entering this, @>Script: set_digit(nil) or just @>Script: set_digit erases the window

And there are two values (FOUR_DIGIT_X & FOUR_DIGIT_Y) that lets you adjust the location on the screen,
