Size Method for Pokémon [Gen 3/4]

[Vendily]

So Essentials already has a method that calculates for size, def pbSize(pokemon) and you just call it from anywhere with a pokemon instance.

You do not need this resource to calculate Size.

So in Gens 3 and 4, there are NPCs who ask to see the biggest Pokémon of a certain species. This is calculated based on the personal ID and IVs. I won't explain the entire formula because Bulbapedia has already done that.

Script: https://pastebin.com/raw/5HuySwRf

So just paste this script in your class PokeBattle_Pokemon and call it on a Pokémon instance. It returns the result in millimeters. Interpret the result however you like.

Hello
Do you know a method to calculate the weight of the Pokémon?

 

[Vendily]

Umm, well, that's not a thing in the games, but you could probably change the height in the last step of the formula to weight.

Hello

I think the game already uses this method for getting the weight of Pokemon for things like Grass Knot or Low Kick.
You should just be able to use attacker.weight for example. Hope this helped. :)

Spoiler:

def weight
    w=(@pokemon) ? @pokemon.weight : 500
    w*=2 if self.hasWorkingAbility(:HEAVYMETAL) && !(self.moldbroken)
    w/=2 if self.hasWorkingAbility(:LIGHTMETAL) && !(self.moldbroken)
    w/=2 if self.hasWorkingItem(:FLOATSTONE)
    w*=@effects[PBEffects::WeightMultiplier]
    w=1 if w<1
    return w
  end

Perfect!

    w=1 if w<1
    return w
  end

I only managed to display the weight of the Pokémon using the Vendily method.

In your case, you mean we can change the power of attacks like Grass Knot or Low Kick by defining the personal weight of the Pokémon?
Cool!
How do you do that?
I thought the game was using the PBS data to execute these moves.

Ok I'm a little bit confused. I don't know what the Vendily method is but other than that the game of course uses the PBS Files to calculate the weight of the Pokemon.
This function:

Spoiler:

def weight
    w=(@pokemon) ? @pokemon.weight : 500
    w*=2 if self.hasWorkingAbility(:HEAVYMETAL) && !(self.moldbroken)
    w/=2 if self.hasWorkingAbility(:LIGHTMETAL) && !(self.moldbroken)
    w/=2 if self.hasWorkingItem(:FLOATSTONE)
    w*=@effects[PBEffects::WeightMultiplier]
    w=1 if w<1
    return w
  end

Leads to this function in PokeBattle_Pokemon:

Spoiler:

# Returns the weight of this Pokémon.
  def weight
    dexdata=pbOpenDexData
    pbDexDataOffset(dexdata,@species,35)
    weight=dexdata.fgetw
    dexdata.close
    return weight
  end

Which of course leads to the dex which gets its data from the PBS Files.

This is an example function of a move that uses the weight calculation, I think this is Grass Knot:

Spoiler:

################################################################################
# Power increases the heavier the target is.
################################################################################
class PokeBattle_Move_09A < PokeBattle_Move
  def pbBaseDamage(basedmg,attacker,opponent)
    weight=[COLOR="Red"]opponent.weight[/COLOR]
    ret=20
    ret=40 if weight>100
    ret=60 if weight>250
    ret=80 if weight>500
    ret=100 if weight>1000
    ret=120 if weight>2000
    return ret
  end
end

You should be able to use this formula in any battle relevant script section since it's directly tied to the individual Pokemon.
Hope this helps. :)

Do you know how I can get the maximum and minimum size and the maximum and minimum weight of a species?
A can like in Pokémon Let's Go.

Sorry, I'm not really sure how to do that, but you can probably play with the variables of the size formulas.

Um, but low IVs (or rather, low least significant bits) have a drastic impact on the size of the mon, so you'd start there.

Hi Vendily,

sorry, I'm really not good at math so don't count on me to follow this method.

I just looked at this site and I found this:

https://www.serebii.net/letsgopikachueevee/pokemonsize.shtml

A Pokémon can have a maximum height of up to 40% and can have a weight of up to 60%.

From this information, things are much simpler.
In addition, we can even see the rates of encounters according to the sizes.
With a can of effort, it is possible to make a script.
(I'll try but I don't guarantee anything. I'm really bad at calculating).

I thought it was necessary to do it manually for every species of Pokémon.
