# * [ACE] Letter Animations
#===============================================================================
# * Made by: Sixth (www.rpgmakervxace.net, www.forums.rpgmakerweb.com)
# * Version: 1.0
# * Updated: 06/01/2019
# * Requires: -------
#-------------------------------------------------------------------------------
# * < Change Log >
#-------------------------------------------------------------------------------
# * Version 1.0 (06/01/2019)
#   - Initial release.
#-------------------------------------------------------------------------------
# * < Description >
#-------------------------------------------------------------------------------
# * This script will let you use image-sheets for the letters in the message
#   window. The letters can be animated using these image-sheets.
#-------------------------------------------------------------------------------
# * < Script Calls >
#-------------------------------------------------------------------------------
# * To change the message box's letter style, use this script call BEFORE the
#   "Show Message" event command:
#
#     set_msg_win_style('style_key', hue)
#
#   Replace the 'style_key' with a valid setting key from the 'Styles' setting
#   area found in this script!
#   You can also use nil here, in which case this script will be disabled until
#   you use this script call again with a valid setting key instead of nil.
#
#   Replace the hue with an integer number between 0 and 360.
#   This will set the hue of the letter images.
#   You can omit this argument, in which case 0 will be used automatically.
#
#   Note that the effect of this script call is saved! Once you use this, the
#   message box letter style will remain on the values you used the last time
#   in this script call, even after loading a saved game!
#
#   Examples:
#
#     set_msg_win_style('default')
#     set_msg_win_style('yellow')
#     set_msg_win_style('curly_blue',126)
#     set_msg_win_style('edgy_yellow_red',80)
#
#-------------------------------------------------------------------------------
# * < Image Setup >
#-------------------------------------------------------------------------------
# * First thing first, you must setup your character images before you can use
#   this script.
#   I won't lie, this can be a pretty boring job, but once it's done, you can
#   use the completed character set any time you want in the future.
# * Each letter style used by this script must be in it's own separate folder!
#   You can setup the folder used for each letter style separately in the script
#   settings, so you have full control over this too.
# * You must have an image for each characters you use in your texts, even if
#   they are only used once during a 120 hours game (which is highly unlikely,
#   but still :D)! However, if you are sure that a character will not appear in
#   a given letter style ever during your game, it is safe to leave that
#   character out from that letter style's folder.
# * The letter image-sheets can have any size (width x height) and the image
#   frames on them can be formatted in any way (rows x columns), but each
#   image frame must have the same width and height!
#   All image frames used in the drawing AND in the idle animation must be on
#   the SAME image-sheet! You can select which image frames to use for which
#   animation, so don't worry about that.
# * The image frames are "numbered" in a specific (and logical) way.
#   The numbering starts from 0 (from the top-leftmost frame) and goes to
#   infinity (to the bottom-rightmost frame).
#   For example:
#
#     -----------------
#     | 0 | 1 | 2 | 3 |
#     -----------------
#     | 4 | 5 | 6 | 7 |
#     -----------------
#
#   You will use these index numbers in the :frames animation settings.
# * The image frames themselves must all have the same height in the same
#   style! This is to let you adjust the vertical positions of your characters
#   manually, since doing this automatically would lead to a pretty convoluted
#   setting area, which is not what most of us want, right?
#   This means that the height of your characters will always be the height
#   between the top of the tallest character and the bottom of the smallest
#   character. Well, this is the only way I can explain it, but if it's not
#   enough, you can check the PSD files in each letter style folder, and check
#   the "Guide Lines" layer folder to see what I mean. I marked the important
#   vertical positioning lines there, so that I always know the vertical
#   positioning of my characters. Note that those layers are only there as a
#   guide, they do not affect anything in this script, nor are they needed for
#   this script to work!
#   Hahh! Got you! This is a copy/paste paragraph from another script of mine,
#   I never really made sample images for this script, sorry! :P
# * There can be no empty pixels on the left or right side on your character
#   images! The automatic character width calculation is based on the width of
#   the character image frames, that's why there should be no useless empty
#   pixels on the sides. The spacing between the characters itself can be setup
#   for each letter styles separately in the script settings, so this part is
#   not on your character images at all.
#   Actually, you can have empty pixels on the image frames used in the drawing
#   animation, since those are most probably incomplete letters until they are
#   fully "drawn" anyway, but make sure that the image frames used in the idle
#   animation don't have empty pixels on the sides!
#   If you can't make the image frames this way, you can still adjust the
#   spacing after specific letters and even between specific letters, so you can
#   still use those images, but you will have a lot more to setup that way.
# * You can have whatever drawn on your character images. This script is meant
#   to be used for text drawing, but that is not the only thing you can draw
#   with it, it all depends on what you have on your character images.
#-------------------------------------------------------------------------------
# * < Installation >
#-------------------------------------------------------------------------------
# * Place this script below Materials but above Main!
# * If you are using my Control Configuration System script, place this script
#   above those scripts!
#-------------------------------------------------------------------------------
# * < Compatibility Info >
#-------------------------------------------------------------------------------
# * No known incompatibilities.
# * There is no word-wrap feature in this script! There won't be one either,
#   unless someone (othar than me) is willing to make an addon for that.
#   This probably means that this script will not work well with word-wrap
#   scripts.
#-------------------------------------------------------------------------------
# * < Known Issues >
#-------------------------------------------------------------------------------
# * No known issues.
#-------------------------------------------------------------------------------
# * < Terms of Use >

  # Letter Image Settings:
  #-----------------------------------------------------------------------------
  # This is where you will setup the character list and their image names.
  # Each character you want to use in any letter style must be specified here.
  #
  # Format:
  #
  #   'character' => 'filename',
  #
  # The character can be any valid character, really.
  # Although, sadly, the font type used in this editor does not support some
  # (well, a lot of) extra character symbols, so you won't be able to set those
  # up here.
  #
  # There are some extra characters which are normally not displayed, but you
  # can still specify a filename for them and use them in your texts.
  # One of them, for example, is the "\t" character, which denotes the paragraph
  # character when the TAB key is pressed.
  # The only special character which is processed automatically is the "\n"
  # character which denotes a line-break. That won't be displayed at all, it
  # will just start a new line, like it would normally.
  #
  # And this is a good place to state that you can insert a manual line-break
  # with the "\n" character in your texts.
  #
  # The list I made contains most of the basic characters (letters, numbers,
  # signs, etc) and some extra ones as well, but it is far from including all
  # of the displayable characters, so feel free to add your own character
  # settings here.
  #
  # The character image filenames you setup here are the default ones for all of
  # your letter styles. You can change the filename for each character in your
  # letter style setting area with the :img option if needed.
  #
  # I have noted some of the settings here with a "No image file setup!" line.
  # That means that these characters don't have a character image for any letter
  # style I made, so they are unusable in your texts until you make an image
  # for them.

  # Letter Style Settings:
  #-----------------------------------------------------------------------------
  # This is the place where you can setup the identifiers, folder, spacing and
  # animation settings for your letter styles.
  # You will use the setting keys from this setting in all letter style related
  # things in the provided script call.
  #
  # Format:
  #
  #   'style_key' => {
  #     :folder => "folder_path/",
  #     :spacing => {
  #       :horz => value,
  #       :vert => value,
  #       'char' => value,
  #       'char1char2' => value,
  #       ...
  #     },
  #     :draw => {
  #       :cols => amount,
  #       :rows => amount,
  #       :frames => [index1, index2, ...],
  #       :wait => value,
  #       :repeat => amount,
  #     },
  #     :idle => {
  #       :cols => amount,
  #       :rows => amount,
  #       :frames => [index1, index2, ...],
  #       :wait => value,

  #       :draw => { * draw_animation_settings_here * },
  #       :idle => { * idle_animation_settings_here * },
  #     },
  #     ...
  #   },
  #
  # You can make as many letter style settings as you want.
  # The 'default' letter style setting must contain ALL setting options
  # (excluding the character specific ones - those are optional even there)!
  # The :folder option is the only one that is mandatory for ALL other letter
  # style settings. If a letter style is missing some other setting options,
  # those will be loaded from the 'default' letter style automatically.
  # For this reason, you should never remove or rename the setting key for the
  # 'default' letter style settings!
  #
  # If you don't use a 'style' argument for the letter style changing script
  # call, the 'default' letter style will be used automatically.
  #
  # Okay, so that's all for the basics...
  # Now lets see the details...
  # I will break this into multiple sections for easier readability.
  #
  #- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
  # 1. Folder settings:
  #
  #   :folder => "folder_path/",
  #
  # A simple option for start.
  # You just enter the path of the folder containing all character images for
  # the letter style here.
  # Don't forget the "/" sign at the end, that is needed!
  #
  # Because there can be no files named the same in the same folder, you must
  # set this up for ALL of your letter style settings!
  #
  #- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
  # 2. Spacing settings:
  #
  #   :spacing => {
  #     :horz => value,
  #     :vert => value,
  #     'char' => value,
  #     'char1char2' => value,
  #     ...
  #   },
  #
  # This one seems a bit longer, but it's still simple enough...
  #
  # First, you have 2 static options:
  # :horz - The default horizontal spacing between the letter images.
  # :vert - The vertical spacing between each line drawn.
  #
  # And than you can add unlimited amount of custom horizontal spacing settings.
  # You can do this 2 different ways:
  #
  # - Use this format: 'char' => value,
  # You must replace the 'char' with a valid setting key from the
  # 'Letters' setting area (found above this setting area).
  # This will make the draw method use the spacing value you specify here AFTER
  # the specified character.
  # Example: 'a' => 1, '!' => 0,
  #
  # - Use this format: 'char1char2' => value,
  # Here you must replace the 'char1char2' part with 2 valid setting keys from
  # the 'Letters' setting area (found above this setting area).
  # This will make the draw method use the spacing value you specify here
  # BETWEEN the 2 specified characters.
  # Example: 'av' => 0, 'BY' => 2,
  #
  # If none of the above 2 custom, letter specific horizontal spacing settings
  # are set, the default value will be loaded automatically instead (from the
  # :horz setting option).
  #
  # The value must be an integer number and it is measured in pixels!
  #
  #- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
  # 3. Animation settings:
  #
  #   :draw/:idle => {
  #     :cols => amount,
  #     :rows => amount,
  #     :frames => [index1, index2, ...],
  #     :wait => value,
  #     :repeat => amount,
  #   },
  #
  # Another bigger setting group.
  # This one will setup the default drawing/idle animation for your letters.
  # Both animation setting groups (:draw and :idle) got the same setting options
  # and layout, so I will just merge the details on them here.
  #
  # When the letter is drawn, it will start out with the :draw animation
  # settings. This will let you make a drawing animation for each of your
  # letters.
  # When this draw animation is finished, the letter will switch to the :idle
  # animation settings. This will let you make a separate animation for the
  # letters when they are "finished the drawing", or you can just simply use it
  # for stopping the animation, and let the letter be static for the rest of the
  # day.
  # The letters will keep appearing one after the other, each waiting for the
  # previous letter's :draw animation to finish. For that reason, you may want
  # to consider using short draw animations with only a few frames or a very
  # quick one with more frames (the latter will definitely look smoother),
  # otherwise the player will get bored of it, or even worse, will get annoyed
  # by it.
  # Note that when the player presses the "skip" or "fast-forward" button, the
  # :draw animation ends immediately for all letters and the whole text will be
  # displayed at once (all letters also switch to their :idle animation).
  #
  # The animation is made by using image-sheets for your letters.
  # This image sheet can be formatted in any way, and can be any size.
  # The :cols and :rows options will setup the formatting of the image-sheet.
  # For example, if you have an image-sheet containing 8 image frames in a
  # 2 x 4 format, you will have to set the :rows setting to 2 and the :cols
  # setting to 4.
  # You don't have to use all image frames from the image-sheet, you have the
  # option to select exactly which frames you want to use and in which order
  # with the next setting option.
  #
  # The :frames setting option will let you setup which image frames you want
  # to use from the image-sheet, how many times you want to use them in the
  # animation cycle and in which order you want to use them.
  # For more information about getting the correct image frame indexes for this
  # setting, head to the "Image Setup" details found in the header of this
  # script.
  # You must enter at least one image frame into this setting array!
  # You can use unlimited amount of image frames here, and you can re-use the
  # same image frame index multiple times as well if needed.
  #
  # The :wait setting option will let you control the speed of the animation
  # cycle. This must be an integer number, 0 or higher!
  # The higher the value you set here, the slower the animation gets!
  #
  # The :repeat option will let you setup how many times the animation cycle
  # repeats before stopping the animation. The animation will stop on the last
  # image frame from the :frames setting option.
  # If you set this to 0, the animation will be blocked completely (so, the
  # drawn letter images will NOT be animated at all), and if you set it to -1,
  # the animation cycle will repeat endlessly.
  # If you set it to 1 or higher, the animation cycle will stop after that many
  # repeats.
  #
  # You may want to setup static (not animated) letters, especially for the
  # :idle animation settings. You can do so by setting the :repeat option to 0,
  # and by entering only 1 frame index into the :frames setting array.
  # The :wait setting is irrelevant in this case, but you must setup a valid
  # value for it still!
  # The rest of the settings must be setup properly, even if you don't want to
  # animate the letter (:cols and :rows).
  #
  #- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
  # 4. Character specific settings:
  #
  #   'char1' => {
  #     :img => "filename",
  #     :draw => { * draw_animation_settings_here * },
  #     :idle => { * idle_animation_settings_here * },
  #   },
  #
  # These setting groups are optional only!
  # With these, you can setup a custom image-sheet name, and animation settings
  # for each of your letters in a letter style.
  #
  # The 'char1' setting key must be replaced by a valid setting key used in the
  # 'Letters' setting area (found above this setting area). The settings in the
  # character specific setting groups will apply to the specified character
  # only!
  #
  # The :img setting option will let you setup a custom image-sheet filename
  # for the letter. I don't recommend using this option. It is much better to
  # just stick with the same filenames for all of your letter styles, since the
  # letter images must be in different folders for each letters styles anyway.
  #
  # The :draw and :idle setting options will setup a custom drawing/idle
  # animation for the letter. This can come in handy, since a drawing animation
  # for the 'M' letter could have more animation frames than, for example, the
  # '!' sign has.
  #
  # All setting options here are optional, so you can leave out the ones you
  # don't want to modify for the letter (they will use the default ones instead
  # that way).
  # But keep in mind that if you use the :draw or the :idle setting groups here,
  # you must setup ALL setting options for those groups (:rows, :cols, :frames,
  # :wait and :repeat)!
  #
  # You can enter unlimited amount of character specific settings here!
