# ▼ Updates
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
#
# 2014.09.24 - Rewrote the script from the ground up, included default settings.
# 2014.01.30 - Added MP Recovery Function.
# 2014.01.25 - Started Script
# 
#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# Based on the Romancing SaGa: Minstrels Song battle system, this script
# modifies MP to behave exactly as it does in Romancing SaGa: Minstrels Song
#
# Currently this script only performs the background functions such as setting.
# Initial BP and the BP Regen Rate.
#
# As far as the visual effect that display BP in game, I have no plans to
# include it at the moment.
#
# On a side note, the BP Mechanic can be completely ignored if you set the
# default Initial and Recovery settings to 100 and 0 respectively. Actors will
# behave much like they would by default if the script wasn't implemented.
#==============================================================================
# ▼ 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.

# -----------------------------------------------------------------------------
# NOTETAGS
#   These note tags can be used within the following locations in the database
# * ACTOR
# * ENEMY
#
# -----------------------------------------------------------------------------
#    
# Initial BP Setup
#
#   <initial bp: x>, <initial_bp: x>, <initialbp: x>
#   * Sets the starting MP value to a percentage of your Max MP.
#
#   ** EXAMPLE **
#   <initial mp: 40>
#   * An actor with a MAX MP value of 20 would start with 8 MP
#   * An actor with a MAX MP value of 13 would start with 5 MP
#
# -----------------------------------------------------------------------------
#
# BP Regeneration
#    <bp recovery: x>, <bprecovery: x>,  <bp_recovery: x>
#
#   * Performs a fixed MP Recovery rate at the end of each turn.
#   * This is was included since the default programs lacks this function in Ace
#  
#   ** EXAMPLE **
#   <mpregen: 4>
#   The actor/enemy will regenerate 4 MP at the end of every turn.
