#  Author: Andrew McKellar (Anaryu) (anmckell@gmail.com)
#
#  Version: 1.3b
#
#  1.2 March 5th 4:15pm EST: Implemented feedback from (Zeriab) and other ideas
#    for updating sprites/events that are off-screen/parallel also added
#    off-screen updating for events that are set with a specific move route.
#  1.2a March 6th 5:09am EST: Changed on_screen to use Graphics module instead
#    of static values. (Zeriab)
#  1.2b March 7th 12:36am EST: Changed Game_Player to use standard functions
#    instead of special ones. Changed empty array check to use proper empty?
#  1.2c March 10th 10:13pm EST: Updated events that used a tile and a character
#    on multiple pages to be drawn as a sprite correctly. (eugene)
#  1.2d March 14th 4:12am EST: Fixed errors with vehicles, passability,
#    and airship landing.
#  1.2e March 18th 1:47am EST: Fixed errors with passability and tileset
#    graphics in multi-page events.
#  1.2f June 9th 4:34pm EST: Fixed errors with diagonal movement having the
#    turn_ok setting passed in while the original functions didn't use it.
#  1.2g June 20th 7:49pm EST: Fixed bugs regarding diagonal movement for
#    events (last update was just player!) and fixed bug with jump function
#    not updating location.
#  1.2h September 20th 10:35am EST: Added a check so changing graphics on a blank
#    event from another event, or using Show Animation or Show Bubble will
#    activate the event automatically and set it to be in use. Also added two
#    new globals to allow you to choose how far off-screen updates will still
#    be performed (see below.) Also fixed efficiency loss by having several
#    math functions in the on_screen function (called constantly) and moved
#    those to initialize function instead.
#  1.2i November 29th 6:14pm EST: Fixed issue with balloon use over non-event
#    characters.
#  1.2j December 22nd 3:59am EST: Fixed issues when 'moveto' or Move Event
#    commands were used.
#  1.3a December 26th 1:02am EST: Fixed layers for events that are 'tile' graphics
#    and made them use the passability. Also added the 'unless $@' to stop the
#    F12 bugs.
#  1.3b August 25th 11:25am EST: Added catch for blank events that are 'Same
#    as character' to count as collidable (following default VX behavior instead
#    of default XP behavior.)
#
#
#
#
#  ** NOTE: You can switch "BLANK_EVENT_COLLISION" by setting it to "XP" now, this
#          maybe be necessary for old projects using this script that depend
#          on events with "None" for graphic to be passable.
#
#  This script modifies background functions, only other low-level or map
#  modification scripts should conflict.
#
#  Please credit if used, no need to ask for permission for commercial use.
#==============================================================================

# If true this will allow the system to ignore all events that are off screen
# unless you add "DOUPDATE" to their name. (DOUPDATE events will always update)
#
# If false this will means the system will ALWAYS update EVERY EVENT on the map
# - this should only be used if you experience weird compatability issues due
# to some custom scripts, it's better to try putting the DOUPDATE flag on events
# that do special things or have special settings that don't work when this
# flag is set to true.
#
# X_OFFSCREEN_SQUARES and Y_OFFSCREEN_SQUARES are how many squares in the X and Y
# direction we should update events. Default of 1 means any event one square
# off-screen will still be updated. The larger this value, the less efficiency
# you will see from the anti-lag system, however it can be used to make large
# events update instead of hang on screen.
#
# BLANK_EVENT_COLLISION defaults now to "VX" and can be changed to "XP" to make
# it not collide and block events, even on the same layer, if their graphic
# is set to 'None' (added so games using this functionality aren't messed up)

ALLOW_SCREEN_IGNORE = true
X_OFFSCREEN_SQUARES = 1
Y_OFFSCREEN_SQUARES = 1
