# * Version 1.0 (24/01/2016)
#   - Initial release.
#-------------------------------------------------------------------------------
# * < Description >
#-------------------------------------------------------------------------------
# * This script will let you set up images for your choices in the choice
#   window. These images will show up when the choice window is opened and will
#   be hidden when the choice window is closed.
# * The images are tied with the choice window's selection cursor, so the image
#   displayed will depend on the selected option in the choice window.
#   In short, only one image will be displayed, and that is based on the
#   cursor's position. The shown image is updated in real time, so the player
#   can see the changes immediately.
#-------------------------------------------------------------------------------
# * < Script Calls >
#-------------------------------------------------------------------------------
# * To set up the images for a "Show Choices" command, use this script call
#   BEFORE the "Show Choices" command:
#
#     set_choice_pics(image_settings)
#
#   The 'image_settings' are your settings for your images.
#   Who would have guessed it, right? :D
#
#   Okay, here is how one image setting looks:
#
#     ["filename",x,y]
#
#   The "filename" is the name of the image file you want to use.
#   The x and y is the X and Y positions of the image (no kidding! :P).
#
#   So, this is one image setting, and you can enter as many as you want.
#   Each of them must be separated by commas!
#   Keep in mind that the maximum choices you can show is 4 unless you use
#   custom scripts to change that, so there is not much point to add more than
#   4 image settings if you do not use scripts to increase that number.
#
#   Examples:
#
#     set_choice_pics(["Yes",250,200],["No",250,200])
#   This would show the "Yes" image when the cursor is on the first choice, and
#   would show the "No" image when the cursor is on the second choice.
#   If there are more than 2 choices, nothing will be shown for the rest of
#   them.
#
#     img1 = ["Easy",120,140]
#     img2 = ["Normal",120,170]
#     img3 = ["Hard",120,200]
#     img4 = ["Insane",120,230]
#     set_choice_pics(img1,img2,img3,img4)
#   This would set 4 images for the first 4 choices.
#   You see, I set up the image settings separately, one on each lines, and
#   pass these settings to the script call as 'img1', 'img2', and so on.
#   This is to keep it organized and because I don't like long script calls
#   horizontally (some parts might get cut in the event command editor when
#   viewing them on the command list).
#   You don't have to use 'img1', 'img2', etc for their names, those are just
#   examples, you can name them however you like, just make sure to use the
#   same names in the 'set_choice_pics' call!
#
#   NOTE1:
#   All images used in these script calls must be in the "Graphics/Pictures"
#   folder of your game!
#   NOTE2:
#   You must set up these images before ALL of your choice selections if you
#   want to show images for your choices, because the settings will get cleared
#   automatically when the choice window is closed!
#   If there is no image settings set up before a "Show Choices" command,
#   there will be no images shown for your choices!
#   NOTE3:
#   You don't have to use this script call exactly before the "Show Choices"
#   command. Once you useed this script call, it will be active all the time
#   until the choice window opens. When that happens, the settings will be
#   cleared the moment the choice window is closed.
