Latest Post

I get an error on line 712.

Script 'PrexCraft' line 712: NoMethodError occurred.
undefined method '[]=' for nil:NilClass

But line 711-717 is:
Code: 
def learn_trade(name)
    @trade_skills[name] = 1
  end
  #-----------------------------------------------------------------------------
  def forget_trade(name)
    @trade_skills[name] = 0
  end

So I need to fix the error in the script, but I don't know how.

# Game_Party

# This is a small edit of the original Game_Party class to add recognition for
# recipes. It also adds the methods below:
#   add_recipe() : name
#     - this will teach the party the recipe, if it's valid. name is the name
#       of the recipe.
#   remove_recipe() : name
#     - this will force the party to forget the recipe, if it's known. name is
#       the name of the recipe.
#   have_recipe() : name
#     - this will return true or false, depending on if the party knows the
#       recipe. Primary used in the can_make? method of the Craft module.
# -- FOR LEVELS --
#   learn_trade() : name
#     - this will set the level of the 'trade skill' to 1, enabling it for use
#       with recipes.
#   forget_trade() : name
#     - this will reset the level of the 'trade skill' to 0.
#   trade_check() : name, level
#     - this will return true or false, depending on if the arguement 'level' is
#       less than or equal to the 'trade skill'.
#   trade_level_up() : name, value = 1
#     - this will add the value to the existing trade level. Used primary by
#       the Craft module.

Do you have any other scripts below this one in the script listings that override Game_Party.initialize? That's the only way @trade_skills would be undefined. Because it's a Hash you could feed it any data and it wouldn't complain. Unless the Hash doesn't exist. That will give you the error you have there.

Code: 
@trade_skills = Hash.new(0)
@trade_skills['monkey'] = 'five'
@trade_skills[8] = Math::PI
p @trade_skills # "{8 => 3.14etc, "monkey"=>"five"}

Would you be willing to create a demo? I truly don't know what the problem could be at this point. If you are worried about privacy feel free to PM me with the information.
