Parameter Points Script (alpha version, no graphics)

#         Parameter Points Script, version 0.1
#         Author: bgillisp
#         Released 9/3/2014

#         This script allows you to earn parameter points upon level up, which
#         you can then spend to increase your stats. The standard level-up
#         process is still present, so you can either have these as bonuses,
#         or you can set the database to give no reward on level up, then
#         these points have to increase your parameters

# To use:
#         Place in the materials folder, but above main
#
#         Currently there is no graphical interface for the points. This means
#         you will never know how many points you have short of a script call.

# To check points, call $game_actors[x].parameter_points in a script call in an
# event. Replace x with the name of the actor (remember the database starts at 1)

# To spend points, call $game_actors[x].spend_parameter_points(y), replacing
# x with the actor's id, and y with value of the stat you wish to spent a point
# to increase. The values to pass are as follows
# 0 - MHP
# 1 - MMP
# 2 - ATK
# 3 - DEF
# 4 - MAT
# 5 - MDF
# 6 - AGL
# 7 - LUK

# If, for some reason, you accidentally pass a number less than 0, the point will
# be spent to increase MHP.
# If, for some reason, you accidentally pass a number more than 7, the point
# will be spent to increase LUK.
#
# If you call the command, but do not have the points to spend, it will do
# nothing.

# Terms of use:
#           Free for use in commercial and non-commercial games, with credit
#           given.
