Problems with SephirothSpawn's Materia System

[Aerif]

So I just added Sephiroth Spawn's Materia System to my game. And everything was going fine until I actually play-tested the game and then I recieved the following error:

Script 'Materia System' line 84: NoMethodError occured.
undefined method '[]' for nil:NilClass

Here is the section where the error occurs:

Spoiler: Line 79 - 87

  #============================================================================
  # ** Weapon
  #============================================================================
  class Weapon
    #--------------------------------------------------------------------------
    # * Public Instance Variables
    #--------------------------------------------------------------------------
    attr_accessor :paired_materia
    attr_accessor :single_materia
    #--------------------------------------------------------------------------
    # * Set Materia Slots
    #--------------------------------------------------------------------------
    def set_materia_slots(slots)
(84)  @paired_materia, @single_materia = slots[0], slots[1]
    end
  end
 

I'm using SDK 2.3 and I really need this error fixed to continue my project

BUMP

Come on, please help, it's esential for continuing the project

hmmm.... give me ten minutes or contact seph

*edit*

ok, so I needed ten seconds

Spoiler: this should work

  #============================================================================
  # ** Weapon
  #============================================================================
  class Weapon
    #--------------------------------------------------------------------------
    # * Public Instance Variables
    #--------------------------------------------------------------------------
    attr_accessor :paired_materia
    attr_accessor :single_materia
    #--------------------------------------------------------------------------
    # * Set Materia Slots
    #--------------------------------------------------------------------------
    def set_materia_slots(slots)
      @paired_materia, @single_materia = slots[0], slots[1]
    end
  end

this is what that section should look like

 

[Aerif]

Actually I only put the 84 there to indicate that that was the problematic line. So that doesn't actually help in the slightest seeing as that's what I have already in the script.

 

[hungery12]

oh, oh, ohhhhh.
well I tried.
when I get home I'll try and figure this out.
but until then.
does this happen right as you playtest the game?

*edit*
not home  but...

rplace your Game_Battler (part 3) with this one

 

[Aerif]

It still doesn't work, but it's alright now, I've found a way round it by using SDK ver. 1.3.

Thanks for your efforts though

 

[hungery12]

never thought of that......
your welcome anyway
