NoMethodError...

[OS]

Hello. I seem to have done something wrong when writing these scripts.

Spoiler

class Game_NPCs < NPC_Database
  NPC_COUNT = 2
  #--------------------------------------------------------------------------
  # * Object Initialization
  #--------------------------------------------------------------------------
  def initialize
    @data = []
  end
  #--------------------------------------------------------------------------
  # * Get NPC
  #     npc_id : npc ID
  #--------------------------------------------------------------------------
  def [](npc_id)
    if npc_id > NPC_COUNT or @npcs[npc_id] == nil
      return nil
    end
    if @data[npc_id] == nil
      @data[npc_id] = Game_NPC.new(npc_id)
    end
    return @data[npc_id]
  end
end

class Game_NPC < NPC_Database
  attr_accessor :id
  attr_accessor :surname
  attr_accessor :middle
  attr_accessor :name
  attr_accessor :age #Used in same-sex marriages (Checked for oldest)
  attr_accessor :sex #gender

 #attr_accessor :mp

 def initialize(npc_id)
   super()
   setup(npc_id)
 end
 
 def setup(npc_id)
  @npc_id = npc_id
  @surname = @npc[i][0]
  @middle = @npc[i][1]
  @name = @npc[i][2]
  @age = @npc[i][3]
  @sex = @npc[i][4]
  @disp = @npc[i][5]
  @bounty = @npc[i][6]
  @lvl = @npc[i][7]
  @hp = 100 #Percentages only
  @items = @npc[i][8]
  @clothes = @npc[i][9]
  @weapon = @npc[i][10]
 end
 
 def id
   return @npc_id
 end
end

I'm getting a NoMethodError, undifined method `[]' for Nil:nilClass on line 3 for this little test when using the above scripts.

Spoiler

class Scene_NPCTest
  def initialize
    @e = $game_npc[1].id
  end
  
  def main
    print @e
    print $game_npc[0].id
    $scene = Scene_Map.new
  end
end

If somebody could help me, I'd be grateful.
Thankee.
Peace Out!

1) $game_npc is probably nil did you set $game_npc to an instance of the class Game_NPCs

2) if not one then this is causing it

@npcs[npc_id]

also what is class NPC_Database?, seems a bit unnecessary to me

^^I have Started making a script similar to this one.

It would handle all NPC Interactions, like they would hang together, like some npc dislike other, predifined movements, like go home shop or etc...

BuT my pc crashed and I need to format and I lost everything... Also I would need a new pathfinding routine since it was pretty laggie.

My script is just designed so that NPCs can become married, can have bounties, and react to the player based on thier disposition. I am also trying to make it so that NPCs can hold items, armour, and a weapon, and trade with other NPCs, the player, and Containers (after I finish Game_OBJ).

EDIT: @Trickster: NPC_Database is where the Developer creates the NPCs. I accidently forgot to post that script, so here it is, as well as the Scene_Title Edit:

Spoiler: NPC_Database

class NPC_Database
  #NPC_COUNT = 2
  def initialize
   #item# = [five item ids]
    item1 = [1, 1, 1, 2, 3]
   #clothes# = [shield, helmit, body_armour, accessory]
    clothes1 = [1, 10, 22, 32]
   #var = [0last_name, 1middle_name, 2first_name, 3age, 4sex, 5marriage, 6disp, 7bounty, 8lvl, 9items, 10clothes, 11weapon]
    n1 = ["Testons", "Testing", "Testy", 14, 1, [false, ], 50, 0, 16, item1, clothes1, 1]
    n2 = ["Killer", "The", "Im", 17, 0, 0, 1000, 23, [1, 1, 1, 2, 3], [1, 10, 22, 32], 1]
    @npc = [n1, n2]
  end
end
