# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# RPG Maker VX Ace comes with a very nice party system. However, changing the
# maximum number of members isn't possible without the aid of a script. This
# script enables you the ability to change the maximum number of party members,
# change EXP rates, and/or open up a separate party menu (if desired). In
# addition to that, you can lock the position of actors within a party and
# require other actors to be in the active party before continuing.
#
#==============================================================================
# ▼ Instructions
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# To install this script, open up your script editor and copy/paste this script
# to an open slot below ▼ Materials/素材 but above ▼ Main. Remember to save.
#
# -----------------------------------------------------------------------------
# Script Calls - These commands are used with script calls.
# -----------------------------------------------------------------------------
# *IMPORTANT* These script calls require the new party menu to be enabled to
# use them. Otherwise, nothing will happen.
#
# lock_actor(x)
# unlock_actor(x)
# This will lock actor x in its current position in the party if the actor is
# in the current party. The actor is unable to switch position and must remain
# in that position until the lock is removed. Use the unlock script call to
# remove the locked status. This script requires the actor to have joined and
# in the current party before the script call will work.
#
# require_actor(x)
# unrequire_actor(x)
# This will cause the party to require actor x in order to continue. If the
# actor isn't in the current party but is in the reserve party, the party menu
# will open up and prompt the player to add the required actor into the party
# before being able to continue. This script call will not function unless the
# specific actor has joined the party, whether it is in the current or reserve.
#
# call_party_menu
# This will open up the party menu. This script call requires for the party
# menu to be enabled to use.
#
#==============================================================================
# ▼ Compatibility
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script is made strictly for RPG Maker VX Ace. It is highly unlikely that
# it will run with RPG Maker VX without adjusting.
