[Resolved] Create a method with a defined instance variable?

[mephisto]

Well, playing with the Seph Tutorial, about the RPG::Class, i was making my own method, so I get to a strange part, maybe this is impossible, or no?.

Imagine that I have a RPG::Class called something, and this something, has a attribute called 'name' and 'amount'..

It's possible do this, to make a shorter class? (I mean, to avoid to create the same method, only with change the name?

  def gain_"something[id].name"(number)

     something[id].ammount += number

  end

Any idea?

Thanks.

Not sure on what you are asking. You could pass the instance, or make a sort of case statement that gets an instance value.

Can you post your entire script?

def gain(instance, n)

  instance.amount += n

end

 

class Something

  attr_accessor :amount

  def initialize

    @amount = 5

  end

end

 

@instance = Something.new

gain(@instance, 3)

 

p @instance.amount # -> 8

Something like that?

Thanks I get my objective

I don't figure about the creation for an argument that Include the instance, now I get this:

Spoiler

class Game_Party

  #--------------------------------------------------------------------------

  # * Public Instance Variables

  #--------------------------------------------------------------------------

  attr_reader   :silver

  attr_reader   :copper

  #--------------------------------------------------------------------------

  # * Alias Listing 

  #--------------------------------------------------------------------------

  alias_method  :meph_curry_gprty_init,  :initialize

  #--------------------------------------------------------------------------

  # * Object Initialization

  #--------------------------------------------------------------------------

  def initialize

    meph_curry_gprty_init

    @silver = 0

    @copper = 0

  end

  #--------------------------------------------------------------------------

  # * Get Currency

  #--------------------------------------------------------------------------

  def gain(currency, n)

    eval("@#{(cur = currency.downcase)} = [[@#{cur} + n, 0].max, 99999].min")

  end

  #--------------------------------------------------------------------------

  # * Lose Currency

  #--------------------------------------------------------------------------

  def lose(currency, n)

    gain(currency, -n)

  end

end

Well that was my objective, now is done thanks to you
