# * Random Item/Pokémon Helper - by FL (Credits will be apreciated)
#===============================================================================
#
# This script is for Pokémon Essentials. It creates a class who helps scripters
# to do random operations.
#
#== INSTALLATION ===============================================================
#
# To this script works, put it above main OR convert into a plugin.
#
#== HOW TO USE =================================================================
#
# Example usage:
#
# helper = PokemonRandomHelper.new
# helper.add(3, :RATTATA)
# helper.add(1, :SPEAROW)
# helper.add(1, :EKANS)
# pbAddPokemon(helper.get, 10)
#
# In this example, player have 60% of receiving a Rattata, 20% for Spearow and
# 20% for Ekans. If a single pokémon name is misspeled, the helper throws an
# error, so you don't need to test all results.
#
# Another example:
#
# helper = ItemRandomHelper.new
# # Throws an error if total isn't 100
# helper.require_weight = 100
# helper.allow_nil = true
# helper.allow_repeat = true
# helper.add(10.5, :POTION)
# # 3% for total. 1% for each item
# helper.add_range(3, [:AWAKENING,:ANTIDOTE,:PARLYZEHEAL)
# # 2% for each item. 6% for total.
# helper.add_copying_weight(2, [:POKEBALL,:GREATBALL,:ULTRABALL])
# helper.add(80.5, nil)
# item = helper.get($game_variables[99]/100.0)
# if item
# pbItemBall(item)
# else
# pbMessage("Nothing found.")
# end
#
#== NOTES ======================================================================
#
# helper.get also accept an seed (same seed, same results). You can use
# helper.get_percentage(value) for getting a value percentage change. For
# items, you can user helper.average_sell_price for average sell price.
#
