BIG MAPS

[DerVVulfman]

Version: 1.7

Introduction
This allows you to chain multiple maps together to make one hellacious big honkin' map!

All seamless, it creates a single map in memory based on the maps you merge together. Save, load, teleport between, so far, it all works!

#==============================================================================
#
#  This allows you to chain multiple maps together to make one hellacious big
#  honkin' map!
#
#                                == * == * ==
#
#  BRANCHES &  Standard use of both 'Conditional Branches' and 'Control
#  CONTROL     Variables' is unhampered by this system.
#  VARIABLES:  Performing both with an event to acquire event data (such as
#              map ID, position, facing direction) only functions on events
#              made within its 'individual map' A map event cannot test the
#              data of  another event  if the  target event  was made  on a
#              different map.
#              EX:  Event 1 on map 3 cannot get data from Event 4 on map 2.
#                   Event 1 on map 3 'can' get data from Event 2 on map 3.
#
#
#  TELEPORT:   Standard teleporting between normal maps remains unchanged.
#              Teleporting to a 'big map' has special attributes:
#              1) Setting coordinates to one  of the  individual maps in a
#                 'big map' permitted.  Placement is adjusted accordingly.
#              2) Using variables to teleport into a 'big map' works.  You
#                 can set  the individual map ID and x/y coordinates.   If
#                 the X/Y coodinates  are outside  of the  individual map,
#                 it may place the player into the next adjoining map.
#
#
#  SET EVENT   See Teleport.  Functionally the same for events, except the
#  LOCATION:   event cannot leave the 'big map'.  No Map ID to set/define.
#              Swapping two events limited to those defined in the indivi-
#              dual map.   Cannot swap events  defined in  different maps.
#
#
#  ANIMATIONS: Unhampered by this system.   The editor's  dropdown menu to
#              set an animation  only permites those events  in that given
#              map.   An event on one map cannot apply  an animation to an
#              event created on another.
#
#  EVENT IDs:  Under normal circumstances, you can view the ID of an event
#              in a script call like @>Script: p event_id
#              This will give you the 'new' ID of the event if it was one
#              added to the accumulated Big Map. Obviously different than
#              the original.  To acquire the original Map anedEvent_ID of
#              the event, use  "p $game_map.old_big_event(event_id)".
#              Newly added,the "$game_map.old_big_event" command will re-
#              turn the map and event ID for the event.   There is also a
#              matching command to get the new ID of an event  based upon
#              its original map and ID values, this being :new_big_event"
#              It is used like  "p $game_map.new_big_event(2,23)".
#
#
#                                == * == * ==
#
#  INCLUDED:  A warning system that tests the following:
#             1) If a map is defined in two or more 'big maps'
#             2) If a map is defined more than once in a single 'big map'
#             3) If a big map is incorrectly defined by the following
#                a) Incorrect dimensions provided
#                b) Insufficient maps to fill defined big map dimensions
#             4) If maps within a big map do not use the same tileset (*)
#
#  (*) NOTE:  All map data regarding tileset, fog, etc. are derived from the
#             first map loaded.   Ensure all maps use the same tileset data.
#
#
#------------------------------------------------------------------------------
#
#  KNOWN / TESTED WITH THE FOLLOWING:
#
#  * Auto Populate by Charlie Fleed  - Functional   Must be below Big Maps.
#  * Tileset Swap by ccoa            - Functional.  Must be above Big Maps.
#  * MGC Mode7 Edit by DerVVulfman   - Functional.  Can be above or below.   **
#    (Until the bitmap render limit is reached)
#  * Fog of War by Wachunga          - Functional.  Must be below Big Maps.  **
#  * Dynamic Maps by Near Fantastica - Failed.      A new system needed.    ***
#  * MiniMaps DVV                    - Failed.
#  * Selwyn's Passable MiniMaps      - Failed.
#  * Pass.. Minimaps by Charlie Fleed-Failed.
#  * Charlie's Passable Minimaps     - Functional. Below Big Maps w Patch
#  * Zeriab's Anti-Lag               - Functional  Must be above Big Maps
#                                                  -for up to 5000 events -
#
#                                == * == * ==
#
#   ** Special map codes defined  by these systems must be in the name of any
#      map where the player  may enter/teleport.  Save Games retain settings.
#
#  *** Dynamic Maps permits events and settings to be stored/saved before one
#      leaves the map.   On returning,  the previously saved data is restored,
#      beneficial for features such as Fog of War.
