# * [ACE] Picture Number Drawing
#===============================================================================
# * Made by: Sixth (www.rpgmakervxace.net, www.forums.rpgmakerweb.com)
# * Version: 1.4
# * Updated: 27/11/2017
# * Requires: -------
#-------------------------------------------------------------------------------
# * < Change Log >
#-------------------------------------------------------------------------------
# * Version 1.0 (11/04/2015)
#   - Initial release.
# * Version 1.1 (13/06/2015)
#   - Added in a safe-check in case an unidentified character is detected.
#   - Added a custom folder setting. From now on, all pictures used by this
#     script must be in the folder set up for them!
# * Version 1.2 (22/06/2015)
#   - Actually added in the safe-check method mentioned in v1.1.
#   - Added an optional argument which will clear the previously drawn numbers
#     automatically if the number is redrawn at the same place.
# * Version 1.3 (07/10/2016)
#   - Just added 2 new methods for getting one number's width and height.
#     It is not necessary to update if you don't need that method.
# * Version 1.4 (27/11/2017)
#   - From now on, you can setup different number of styles (rows) and number of
#     characters (columns) for each of your image sheets.
#-------------------------------------------------------------------------------
# * < Description >
#-------------------------------------------------------------------------------
# * This is a scripter's tool, so it won't do anything by itself!
# * This script adds a new method for Bitmap objects.
#   This new method enables the drawing of numbers with pictures.
# * Besides numbers, any other character can be added to the image sheet.
#   These extra characters can be drawn with pictures too.
#-------------------------------------------------------------------------------
# * < Usage Information >
#-------------------------------------------------------------------------------
# You can use the new picture drawing method for numbers by calling the
# following on a bitmap object:
#
#   draw_numbers(x,y,num,opa,al,clear?)
#
# Arguments:
#
#   x = The X position to draw the number on the bitmap.
#   y = The Y position to draw the number on the bitmap.
#   num = The number to be drawn. It supports negative and float numbers too,
#         as long as you define an extra char at the settings below for the
#         minus and point signs.
#   opa = The opacity level of the drawing. If omitted, 255 will be used
#         automatically. Valid values: 0 - 255.
#   al = The alignment used for the drawing.
#        It works a bit different, not like draw_text's alignment, but it will
#        do the alignment just fine.
#        You can choose from 3 values here:
#        0 = Left alignment, 1 = Middle alignment, 2 = Right alignment.
#        Depending on which alignment mode you choose, the X co-ord used in the
#        method call will mean different things:
#        0 - The X co-ord defines the starting point of the drawing.
#        1 - The X co-ord defines the center of the drawing.
#        2 - The X co-ord defines the end of the drawing.
#        If this setting is omitted, 0 will be used by default.
#        Check the example scene to see the differences in practice!
#   clear? = This is either true or false. If true, any previously drawn number
#            at the same place will get cleared automatically. If false, there
#            will be no automatic clearing, so you will need to do it manually!
#            If omitted, this argument defaults to false!
#
# You can change the default drawing style (the default image file and row used)
# too if you want. More info on that can be found below in the next section.
#
# Examples:
#
#   contents.draw_numbers(10,30,$game_actors[1].hp)
# Draws the HP of the actor with ID 1, using the default image file from the
# Pictures folder, and will use the default row on the picture.
# This example is executed in a Window class.
#
#   @example = Sprite.new
#   @example.bitmap = Cache.picture("examplepic")
#   @example.bitmap.num_style = ["numpics2",3]
#   @example.bitmap.draw_numbers(10,14,$game_party.gold,180,2)
# Draws the party's gold on the @example sprite's bitmap, uses the "numpics2"
# image file from the Pictures folder, uses the third row on the "numpics2"
# picture, and draws the numbers with an opacity level of 180.
# The drawing will use right alignment.
#- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
# You can change the bitmap's picture used for drawing the numbers by setting
# it's "style" directly like this:
#
#   bitmap_object.num_style = ["pic",row]
#
#   pic = The name of the image used for the drawing.
#         It must contain at least all 10 numbers, from 0 to 9.
#         The image itself is a sheet of number pictures lined up.
#         Each row equals a new style for the number drawing method.
#         The numbers on the sheet must start from 0 and they increment from
#         the left to the right one by one.
#         If you need special characters, such as a - sign for negative numbers,
#         or a . for float numbers, you must put them after the number pictures!
#   row = The row used from the image. You can create more styles on the same
#         image if you want, by simply inserting another sheet below the last
#         one. You can than change the styles used dynamically with the
#         draw_numbers method easily.
#         Useful if you want to pack all of your number drawing styles into
#         one single image file.
#
# So, this sets a new "style" for the number drawing method, just like you would
# set a new font type/size/etc for a regular draw_text method before drawing
# your stuffs if needed. Take a look at the example scene to see an example!

# Settings:
#===============================================================================
module PicNumbers # <-- No touchy-touchy!
  #-----------------------------------------------------------------------------
  # Image Folder Settings:
  #-----------------------------------------------------------------------------
  # Set up a custom folder where your number pictures will be read from.
  # All pictures used must be in this folder!
  #-----------------------------------------------------------------------------
  ImgFolder = "Graphics/Numbers/"

  #-----------------------------------------------------------------------------
  # Image Sheet Settings:
  #-----------------------------------------------------------------------------
  # Set how many rows and columns are on your image files used for the
  # number drawing methods.
  # From v1.4, you can use different rows and columns for your different
  # image-sheets!
  # The rows represent the number of available styles on the image,
  # while the columns represent the number of characters in one style
  # including the extra characters set up in the next section.
  #
  # Example format:
  #
  # ---------------------------------------------------------
  # | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | + | - | . | , | <- Style 1 (row 0)
  # ---------------------------------------------------------
  # | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | + | - | . | , | <- Style 2 (row 1)
  # ---------------------------------------------------------
  # | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | + | - | . | , | <- Style 3 (row 2)
  # ---------------------------------------------------------
  #
  # This example image setup contains 3 styles. Each row is a style.
  # Changing the 'row' value in the num_style property of a bitmap will change
  # the style used for the drawing.
  # The first row's index is 0, the second row's index is 1, and so on.
  # The example image got 4 extra characters in it (+/-/./,).
  # The width of each section must be the same for all of them!
  # The height of each section must be the same for all of them!
  # The width and height used can differ for each image, but for optimal
  # drawing, keep the characters close to each other horizontally.
  #
  # And the setting's format here looks like this:
  #
  #   "filename" => [rows,columns],
  #
  # The "filename" must be the file name of an image-sheet used for this script.
  #
  # The rows and columns in the arrays must be positive integer numbers, and
  # they will setup the number of styles (rows) and characters (columns) for
  # the specified image-sheet.
  #
  # You can add as many as you like!
  #
  # If an image-sheet got no setting here, it will automatically use the
  # "default" settings!
  #-----------------------------------------------------------------------------
  Formats = {
    "default"      => [3,17], # <-- Default, do NOT remove!
    "numsheet1a"   => [5,17],
    "numsheet_s24" => [6,17],
    "numsheet_big" => [3,17],
    "pages1a"      => [1,17],
    "menu1a"       => [3,18],
    # <-- Add more settings here if needed!
  }

  #-----------------------------------------------------------------------------
  # Default Drawing Style Settings:
  #-----------------------------------------------------------------------------
  # If a bitmap got no style settings set up for drawing the numbers, than this
  # style will be used by default.
  #
  # Format:
  #
  #   DefStyle = ["image file name", row]
  #-----------------------------------------------------------------------------
  DefStyle = ["pacg_nums",0]

  #-----------------------------------------------------------------------------
  # Extra Character Settings:
  #-----------------------------------------------------------------------------
  # The extra character setup.
  # For negative numbers, you must define the "minus" ( - ) sign!
  # For float numbers, you must define the "point" ( . ) sign!
  # You can also add any other characters if you want.
  #
  # Format:
  #
  #   "char name" => column index,
  #
  # The "char name" is the character itself.
  # The column index is the column reserved for the character on the sheet.
  # The first column's index is 0, the second column's index is 1, and so on.
  # Valid values for the column index start from 10 and goes to infinity.
  # The first 10 columns are reserved for the numbers, that is why you
  # can NOT use any numbers below 10 here!
  #
  # If the number drawing method detects an undefined character which is not a
  # number, it will draw an empty space instead and jumps to the next one!
  #-----------------------------------------------------------------------------
  ExtraChars = { # <-- No touchy-touchy!
    "+" => 10,
    "-" => 11,
    "." => 12,
    "," => 13,
