#
#  Change Resolution in game :
#      $resolution.change_resolution(width, height)
#
#  Enable / Disable the script :
#      $resolution.enable(true / false)
#
#  Change Tile in game :
#      $game_map.change_tile(x,y,layer,tile_id)
#
#  Note that X in the notes below means that it's no longer true
#
#  If you're using RGSS3, don't use map larger than 20 x 15 or
#  resolution larger than 640 x 480
#

# KK20's Notes
#==============================================================================
# Introduction:
#
#   This script is intended to create screen resolutions other than 640 x 480.
#   The script comes with its own Tilemap rewrite in order to combat larger
#   screen resolutions (because anything beyond 640 x 480 is not drawn).
#
# Instructions:
#
#   Place script above 'Main'. Probably best to put it below all your other
#   custom scripts.
#   This version does not require the 'screenshot.dll'.
#
# Things to Consider:
#
#  X Fullscreen will change the resolution back to 640 x 480. A solution is in
#    the works.
#  - Transitions do not work properly on larger resolutions. You can use a
#    Transitions Add-Ons script if you want better transitions (otherwise, all
#    you will get is the default fade in/out). Links listed below.
#  - Custom scripts that draw windows to the screen will probably need edits.
#  - Larger resolutions = more processing power = more lag

# ForeverZer0's Notes from v0.93                   (outdated information)
#==============================================================================
# Introduction:
#
#   My goal in creating this script was to create a system that allowed the
#   user to set the screen size to something other than 640 x 480, but not have
#   make huge sacrifices in compatibility and performance. Although the script
#   is not simply Plug-and-Play, it is about as close as one can achieve with a
#   script of this nature.
#
# Instructions:
#
#  X Place the "screenshot.dll" from Fantasist's Transition Pack script, which
#    can be found here: http://sendspace.com/file/yjd54h in your game folder
#  - Place this script above main, below default scripts.
#  - In my experience, unchecking "Reduce Screen Flickering" actually helps
#    the screen not to flicker. Open menu with F1 while playing and set this
#    to what you get the best results with.
#
# Features:
#
#  X Totally re-written Tilemap and Plane class. Both classes were written to
#    display the map across any screen size automatically. The Tilemap class
#    is probably even more efficient than the original, which will help offset
#    any increased lag due to using a larger screen size with more sprites
#    being displayed.
#  - Every possible autotile graphic (48 per autotile) will be cached for the
#    next time that tile is used.
#  - Autotile animation has been made as efficient as possible, with a system
#    that stores their coodinates, but only if they change. This greatly
#    reduces the number of iterations at each update.
#  X System creates an external file to save pre-cached data priorities and
#    autotiles. This will decrease any loading times even more, and only takes
#    a second, depending on the number of maps you have.
#  - User defined autotile animation speed. Can change with script calls.
#  - Automatic re-sizing of Bitmaps and Viewports that are 640 x 480 to the
#    defined resolution, unless explicitely over-ridden in the method call.
#    The graphics themselves will not be resized, but any existing scripts that
#    use the normal screen size will already be configured to display different
#    sizes of graphics for transitions, battlebacks, pictures, fogs, etc.
#  X Option to have a log file ouput each time the game is ran, which can alert
#    you to possible errors with map sizes, etc.
#
# Issues/Bugs/Possible Bugs:
#
#   - Graphic related scripts and your graphics will need to be customized to
#     fit the new screen size, so this script is not for everyone.
#   X The Z-axis for the Plane class, which is used for Fogs and Panoramas has
#     been altered. It is now multiplied by 1000. This will likely be a minor
#     issue for most, since this class is very rarely used except for Fogs and
#     Panoramas, which are already far above and below respectfully.
#   - Normal transitions using graphics cannot be used. With the exception of
#     a standard fade, like that used when no graphic is defined will be used.
#     Aside from that, only special transitions from Transition Pack can be
#     used.

  SCREEN = [1024,576]
  # Define the resolution of the game screen. These values can be anything
  # within reason. Centering, viewports, etc. will all be taken care of, but it
  # is recommended that you use values divisible by 32 for best results.

  UPDATE_COUNT = 8
  # Define the number of frames between autotile updates. The lower the number,
  # the faster the animations cycle. This can be changed in-game with the
  # following script call: $game_map.autotile_speed = SPEED

  USE_CR_SPRITE = true
  # Replace unused sprite in tilemap with a dummy, still in experimental phase.
