# ** TDS Stat Distribution
#    Ver: 1.2
#------------------------------------------------------------------------------
#  * Description:
#  This script allows you to set and change a character's parameters from a 
#  custom menu.
#------------------------------------------------------------------------------
#  * Features: 
#  Change character stats(Parameters).
#  Setting unique stat boosting caps for characters.
#  Setting unique stat increases for characters.
#------------------------------------------------------------------------------
#  * Instructions:
#
#  To gain or lose parameter points, use this in a script call from an event:
#
#    gain_param_points(actor_id, value)
#    lose_param_points(actor_id, value)
#
#    actor_id = ID of actor to gain or lose param points
#    value = amount of param points to gain or lose
#
#    Example:
#
#    gain_param_points(1, 100)    
#
#    lose_param_points(1, 50)
#
#  To set the amount of parameter change points obtained for a character, add this
#  to to the actor's note box:
#
#    <Level_UP_Change_Points: V>
#
#    V = Amount of points to gain everytime the actor levels up.
#
#    Example:
#
#    <Level_UP_Change_Points: 10>
#
#  To set the parameters that can be changed on a character add this to the
#  actor's note box:
#
#    <Change_PARAMS: P P P P P>
#
#    P = Parameter ID. The Id of the parameter from 0 to 7.
#   
#    Example: 
#
#    <Change_PARAMS: 0 1 2 3 4 5 6 7>
#
#  To set the amount of parameter change for spent each parameter point add this
#  to the actor's note box:
#
#    <PARAM_"PNAME"_Value: Value>
#
#    "PNAME" = Parameter short name. (HP, MP, ATK, DEF, MAT, MDF, AGI, LUK)
#    Value = Parameter change value. (Amount to increase per point)
#
#    Example:
#
#    <PARAM_HP_Value: 10>
#    <PARAM_ATK_Value: 1>
#
#  To set the parameter cap for a character, add this to the actor's note box:
#
#    <PARAM_"PNAME"_Cap: Value>
#
#    "PNAME" = Parameter short name. (HP, MP, ATK, DEF, MAT, MDF, AGI, LUK)
#    Value = Parameter cap value.
#
#    Example:
#
#    <PARAM_HP_Cap: 9999>
#    <PARAM_ATK_Cap: 300>
#------------------------------------------------------------------------------
#  * Notes:
#  Paremeter ID List:
#    0: HP - Hit Points  (HP)
#    1: MP - Magic Ponts (MP)
#    2: Attack  (ATK)
#    3: Defense (DEF)
#    4: Magic Attack Power  (MAT)
#    5: Magic Defense Power (MDF)
#    6: Agility (AGI)
#    7: Luck (LUK)
