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

[DPhoenix29]

First of all, I've been using RPMXP since July 2011 and I also own RPG Maker 1 and 2, so I do have experience using different RPG Makers (I'm just new to these forums). I also know next to nothing about scripting in RPMXP besides putting them into a game/editting some numbers/text where it says to edit it.

My issue is, I have 4 events that I want to display a different number (one to display the ones digit of a variable, one for the tens, hundreds and thousands digit). My only problem is I'm not quite sure how to go about doing that.

Variable #0 = 6532. Event 1 = page 6 (which has the graphic of a 6), 2 = page 5, 3 = page 3, 4 = page 2.

The simplest ways I can think to do what I want is make 4 variables, #1 = 6 (event 1 page 6: Condition = variable #1 is 6 or above, which in turn will make then event show a 6), #2 = 5, #3 = 3, #4 = 2.

>>So to sum all that up so it might possibly make sense: I need a script that makes 4 different variables equal the 4 digits (or 5+ digits/variables if needed) of variable #0 (and simple enough that I can easily change what each different variable is) AKA this: http://dl.dropbox.com/u/26636904/picture.png.

So hopefully this will makes sense to someone who can help me with my little problem

thanks, DPhoenix29

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,

Health/Magic (HP/MP) display, I'm pretty much making a battle system using events (something I've done using RPG Maker 1 and 2). The script you gave works but doesn't really do what I need it to do.


Here's some pics of what I'm trying to do with the whole thing (might make it easier to figure out what I want)

I don't know anything about scripting and I want my game to have my own personal battle system, so I'm building it in a way that I can figure out how to build it (so while scripting a battle system might work better, I'm unable to do that, so this will have to do).

All I need is a script that makes the following (which would probably achieve what I need so the event based health display to work)

var502 = thousands place of var501 (if var501 = 6532, var502 = 6, if var501 = 2109, var502 = 2,)
var503 = hundreds place of var501 (if var501 = 6532, var503 = 5, if var501 = 2109, var503 = 1,)
var504 = tens place of var501 (if var501 = 6532, var504 = 3, if var501 = 2109, var504 = 0,)
var505 = ones place of var501 (if var501 = 6532, var505 = 2, if var501 = 2109, var505 = 9,)

varTenThousands = Ten-thousands place of var501 (if I needed a 5 digit number)
varHundredThousands =
Hundred-thousands place of var501 (if I needed a 6 digit number)
varMillions = Millions place of var501 (if I needed a 7 digit number)
etc.

Okay...

Let's consider you have one event with 10 pages tied to a variable [0011: Var1],
another event with 10 pages tied to a variable [0012: Var2],
another event with 10 pages tied to a variable [0013: Var3],
and finally an event with 10 pages tied to a variable [0014: Var4].

Each event has a charset image from '0' to '9'...

And that you're using an event [0010: VarPrime] to hold the initial value of your HP or MP that you want sliced -n- diced for your four events.

Below is some classic event coding that can be used within an event (or more likely a common event) that will take the value stored in [0010: VarPrime] and divide it for use within the first 4 values/events earlier noted. There are two other variables in the below code that are used for storage and calculations.

I also included 'comments'... just in case.

Enjoy.

I normally don't event, but this is classic stuff

Code:

@>Comment:  Initialize Values
@>Control Variables: [0015: VarTemp1] = Variable [0010: VarPrime]
@>Control Variables: [0015: VarTemp2] = 0
@>Comment:  Set 1000's
@>Control Variables: [0015: VarTemp1] /= 1000
@>Control Variables: [0014: Var4] = Variable [0015: VarTemp1]
@>Comment:  Add 1000's to the Temp 2 Value
@>Control Variables: [0015: VarTemp1] *= 1000
@>Control Variables: [0016: VarTemp2] += Variable [0015: VarTemp1]
@>Comment:  Set 100's
@>Control Variables: [0015: VarTemp1] = Variable [0010: VarPrime]
@>Control Variables: [0015: VarTemp1] -= Variable [0016: VarTemp2]
@>Control Variables: [0015: VarTemp1] /= 100
@>Control Variables: [0013: Var3] = Variable [0015: VarTemp1]
@>Comment:  Add 100's to the Temp 2 Value
@>Control Variables: [0015: VarTemp1] *= 100
@>Control Variables: [0016: VarTemp2] += Variable [0015: VarTemp1]
@>Comment:  Set 10's
@>Control Variables: [0015: VarTemp1] = Variable [0010: VarPrime]
@>Control Variables: [0015: VarTemp1] -= Variable [0016: VarTemp2]
@>Control Variables: [0015: VarTemp1] /= 10
@>Control Variables: [0012: Var2] = Variable [0015: VarTemp1]
@>Comment:  Add 10's to the Temp 2 Value
@>Control Variables: [0015: VarTemp1] *= 10
@>Control Variables: [0016: VarTemp2] += Variable [0015: VarTemp1]@>Comment:  Set 100's
@>Comment:  Set 1's
@>Control Variables: [0015: VarTemp1] = Variable [0010: VarPrime]
@>Control Variables: [0015: VarTemp1] -= Variable [0016: VarTemp2]
@>Control Variables: [0011: Var1] = Variable [0015: VarTemp1]

Oh, and RPGMaker XP doesn't have a 'call map event' feature like earlier versions, but then again, you can always use Call Map Event, a script that returns the feature.

The code for the variables worked perfectly (I guess scripts aren't the answer in this case) and the call_map_event script works as well. Thank you very much for the help
