call_map_name (map_id, max_chars)
      map_id    : the ID of the map you want the player to name
        max_chars : the maximum number of characters for the name. This
          defaults to 10 if not set by you.

#    Player-Named Maps
#    Version: 1.0
#    Author: modern algebra (rmrk.net)
#    Date: December 8, 2009
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Description:
#    This script allows you to call a scene that lets the player change the
#  name of the maps. It only really makes sense if you have another script
#  that shows the names of the maps.
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Instructions:
#    Place this script in your editor, above Main and below the default scripts
#
#    To call the map naming scene, use this code in a call script:
#      call_map_name (map_id, max_chars)
#        map_id    : the ID of the map you want the player to name
#        max_chars : the maximum number of characters for the name. This
#          defaults to 10 if not set by you.
#
#    This script requires you to have a dummy actor who never appears in the
#  game and ought not be setup - it is his face graphic that will show up in
#  the map naming screen, so if you wanted to have the map represented by a
#  96x96 graphic you could import it as a face graphic and set it on the dummy
#  actor immediately prior to calling the map naming screen. Otherwise leave
#  it blank. To set the ID for that actor, go to line 45 and change the number
#  to the ID of that dummy actor. You may also determine whether you want the
#  database name of the map to initially show up while setting the name or
#  whether you just want it to be blank at line 48
