Party Switcher Addon for Tsukihime's Party Manager by Sixth

#===============================================================================
# * [ACE] Party Switcher Addon
#===============================================================================
# * Made by: Sixth (www.rpgmakervxace.net, www.forums.rpgmakerweb.com)
# * Version: 1.3
# * Released: 21/01/2015
# * Requires: Tsukihime's Party Manager script
#-------------------------------------------------------------------------------
# * < Change Log >
#-------------------------------------------------------------------------------
# * Version 1.0 (07/12/2014)
#   - Initial release.
# * Version 1.1 (10/12/2014)
#   - Fixed a crash issue that happened when the current party ID got into the
#     reserved party list. Switching the party afterwards resulted in a crash.
#     No idea why would anyone do this, but it is crash-proof now for sure.
#   - The reserve party script call will no longer add party IDs to the list
#     which are already included in the reserved list. This messed up the correct
#     order of party switching in certain cases.
# * Version 1.2 (14/12/2014)
#   - Fixed the check for Falcao's Interactive Tools System.
#     There won't be any more crash because of that check! Sorry about those!
# * Version 1.3 (21/01/2015)
#   - Fixed the initialization of the reserved party list.
#-------------------------------------------------------------------------------
# * < Description >
#-------------------------------------------------------------------------------
# * This script makes party switching as easy as a button press.
#   Separate button triggers for switching to the previous and next party!
# * Reserved parties option, to prevent changing party to some specific parties
#   you reserved for whatever reason(s)!
# * Enable/disable party switching on the fly whenever you want!
# * Add/remove parties to/from the reserved parties list on the fly!
#-------------------------------------------------------------------------------
# * < Script Calls >
#-------------------------------------------------------------------------------
# * To enable/disable the button trigger for the party switching, you can use
#   the following script calls:
#
#     pm_party_switcher(true)  # Enables the party switching.
#     pm_party_switcher(false) # Disables the party switching.
#
# * To add/remove parties to/from the reserved parties list, you can use the
#   following script calls:
#
#     pm_reserve_party([party_ids]) # Adds the parties to reserve.
#     pm_release_party([party_ids]) # Removes the parties from reserve.
#
#   Replace 'party_ids' with any number of party IDs.
#   Examples:
#
#     pm_reserve_party([2,3]) # Adds the parties with ID 2 and 3 to reserve.
#     pm_release_party([4])   # Removes the party with ID 4 from reserve.
#
#   NOTE: Do not ever add the same party ID as your current party's ID to the
#         reserve party list! Make sure that never happens or you will get an
#         error coming your way when you want to change parties!
#
#   No more script calls! o.o
#-------------------------------------------------------------------------------
# * < Installation >
#-------------------------------------------------------------------------------
# * In the script editor, place this script below Tsukihime's Party Manager and
#   above Main.
#-------------------------------------------------------------------------------
# * < Compatibility Info >
#-------------------------------------------------------------------------------
# * This script isn't compatible with "Khas Pixel Movement" script...
#   At least when I last checked, this was the case.
#   If this has been changed since then, please let me know!
# * Includes compatibility with the following scripts:
#   - FA: Interactive Tools
#   - CSCA: Dungeon Tools
#   You won't be able to switch parties when the player uses a hook or has
#   something picked up, for example.
#-------------------------------------------------------------------------------
# * < Known Issues >
#-------------------------------------------------------------------------------
# * No known issues that I know of.
#-------------------------------------------------------------------------------
# * < Terms of Use >
#-------------------------------------------------------------------------------
# * Free to use for whatever purposes you want.
# * Credit me (Sixth) in your game, pretty please! :P
# * Posting modified versions of this script is allowed as long as you notice me
#   about it with a link to it!

module Party_Switcher_S

  Next_Button = :L # Button for switching to the next available party.
  Prev_Button = :R # Button for switching to the previous available party.

  # Reserved parties. The numbers in the array represent party IDs.
  # Parties with these IDs can never get selected with the party switcher buttons.
  # It is recommended to have at least one reserved party, which can act as a
  # placeholder in case all of your other parties are at maximum party member
  # capacity. If this ever happens, the remaining party members can stay in these
  # parties and are available at a later point in the game to be synchronized
  # with the other parties. These parties will hold their inventory as well, so
  # you can bring up the party trade menu anytime if you ever need to get some
  # items from these parties.
