y not a combination so say

case recipe_id
when 1 then item_id[1 => 2]

i dont know anything about hashes so what do you think

[G_G]

whats that suppose to do? thats exactly how I have it setup but I dont know how to access the 1 andc 2 at different times

[nathmatt]

ok it heres what i found

index(val) 
Returns the key corresponding to val. If there is no corresponding element, returns nil.

If there are multiple corresponding keys, arbitrarily returns one of them.

self[key] 
Returns the value mapped to key. If the corresponding key is not registered, returns the default value (or nil if not specified).

that's the only thing i can find not sure how you implement them so looks like index(val) would get 1 from 2

and self[key] would get 2 from 1 in {1=> 2}

edit does that help at all because i don't think there is a way to get the key without using the val or the val without the key there might be but i don't see it in the help file

$hash = {1 => 2, 3 => 4}

$hash[KEY]
$hash[1] would return 2
$hash[3] would return 4

And look at the other methods for more info and stuff.

[G_G]

okay so we wouldnt be able to get the actual 1 then would we by using 0? Dangit oh well.

[Blizzard]

You can get the key from the value as well.

hash.index(value) # returns the mapped key

Remember my config methods?

case id
when 5 then return 'Test 1'
when 7 then return 19
end

It's almost the same like a hash, but only one-way.

$hash = {}
$hash[5] = 'Test 1'
$hash[7] = 19

Why are hashes useful? The key and the value can be anything while in an array the "key" (actually index) can only be a number. Also, in hashes you can use any number as key while in an array the indices start from 0. Hashes are usually used to connect two values (i.e. like in Blizz-ABS actor action observation subsystem the actor is the key and the damage is the value).

[G_G]

yea but is it possible at all to get the first key? Because I'm making a cooking script, So the first key in the hash might be 5 or 33. I plan on releasing it so I dont know if someone else is going to put 33 as the first ingredient.

So is it possible to access the first one without inputing the key?

EDIT:
can we at least put an array inside an array? so its like this
when recipe_id then return [[item_id, amount], [item_id, amount]]
and if so how would I access the first array andc the numbers in it?

[Aqua]

$array = [[5, 1], [2, 2]]

$array[0] = [5, 1]
$array[1] = [2, 2,]

$array[0][0] = 5
$array[0][1] = 1


Unless my mind is still sleeping, and I messed up

[Ryex]

no you not sleeping you got it right Aqua
@game_guy
also note that you can add as many levels to your array as you want

$bla = [[[5, 6], [4, 3]], [[2, 7], [8, 1]]]


$bla[0][0][0] => 5
$bla[0][1][1] => 3
$bla[1][0][1] => 7

Need help sorting an array. I tried the example from the help file but it didnt work...I want it for my skillshop so like how would I sort it alphabetical, reverse alphabetical, or by id?

Here's my window I just need to sort the @data array.

Spoiler: ShowHide

class Window_SkillBuy < Window_Selectable
  def initialize(shop_goods)
    super(0, 128, 368, 352)
    @skill_shop_goods = shop_goods
    self.active = false
    refresh
    self.index = 0
  end
  def skill
    return @data[self.index]
  end
  def refresh
    if self.contents != nil
      self.contents.dispose
      self.contents = nil
    end
    @data = []
    for i in 0...@skill_shop_goods.size
      skill = $data_skills[@skill_shop_goods[i]]
      if skill != nil
        @data.push(skill)
      end
    end
    @item_max = @data.size
    if @item_max > 0
      self.contents = Bitmap.new(width - 32, row_max * 32)
      for i in 0...@item_max
        draw_item(i)
      end
    end
  end
  def draw_item(index)
    skill = @data[index]
    price = skill.price
    enabled = (price <= $game_party.gold)
    if enabled
      self.contents.font.color = normal_color
    else
      self.contents.font.color = disabled_color
    end
    x = 4
    y = index * 32
    rect = Rect.new(x, y, self.width - 32, 32)
    self.contents.fill_rect(rect, Color.new(0, 0, 0, 0))
    bitmap = RPG::Cache.icon(skill.icon_name)
    opacity = self.contents.font.color == normal_color ? 255 : 128
    self.contents.blt(x, y + 4, bitmap, Rect.new(0, 0, 24, 24), opacity)
    self.contents.draw_text(x + 28, y, 212, 32, skill.name, 0)
    self.contents.draw_text(x + 240, y, 88, 32, price.to_s, 2)
  end
  def update_help
    @help_window.set_text(skill == nil ? "" : skill.description)
  end
end

STCMS, just find where I sort the items by ID, name and quantity. After you sort, you can simply use .reverse or reverse! to reverse the order of all elements.

[G_G]

I tried that and I get a wrong number of arguments (0 of 1) thing...

[Blizzard]

Make sure you know what you are sorting.

[G_G]

Yea skills, it pushes $data_skills in it, and I figured the a.name, and b.name would be great so I tried copying that and I kept getting an error. I'll try again.

EDIT: I'm retarded, I kept calling my skill shop wrong, nothing was wrong at all XD

EDIT 2: Okay I know how to actually create a new weapon using this

new_weapon = RPG::Weapon.new
new_weapon.id = x
ect.

Now is there anyway to dump that weapon into the Weapons.rxdata without erasing all the other weapons?

EDIT 3:
Okay I got it. It dumps the weapon into $data_weapons[id] then it dumps $data_weapons into Weapons.rxdata

One more question, say I create another .rxdata file and store it in the Data folder. When the game's encrypted will the game be able to still read it?

[Ryex]

this thread now has so many answers to basic scripting questions it could be called a tut! lol

[G_G]

I declare this the General RGSS/RGSS2 Help Topic *hint hint sticky sticky*

[Aqua]

Make the 1st post look better, and I'll sticky it for you. XD

Not a lot of us know how to RGSS2 though... o.o
Not sure how many could actually help with that XD

[G_G]

how's that?

oh and I could probably help

[Aqua]

After fixing some grammar issues...
*stickies*

[G_G]

Yea I know a bit about rgss2 enough to get me by anyways.

But I still need this question answered.
say I create another .rxdata file and store it in the Data folder. When the game's encrypted will the game be able to still read it?
