[Scripting Question] Form change on evolution screen

[R1P2R1P]

First of all, sorry for my bad English. I have created a script in which Mime Jr., when female and knowing Mimetic, evolves into regular Mr. Mime. However, if it is male and knows Mimetic, it evolves into Galarian Mr. Mime and when a male Mime Jr. knows Mimetic, it evolves into Galarian Mr. Mime. The evolution code works fine. The problem occurs during the evolution screen, where the sprite of regular Mr. Mime is shown instead of the Galarian form.

Here below is the evolution method code and the evolution screen code

Evolution method code

GameData::Evolution.register(
  :id            => :MimeJrGenderMove,
  :parameter     => nil,  # No necesitamos pasar ningún parámetro aquí
  :level_up_proc => proc { |pkmn, parameter|
    # Verificar si el Pokémon es Mime Jr. y si conoce el movimiento Mimético
    next false unless pkmn.species == :MIMEJR
    next false unless pkmn.hasMove?(:MIMIC)
    next true  # Evolucionar si cumple las condiciones
  },
  :after_evolution_proc => proc { |pkmn, new_species, parameter, evo_species|
    # Determinar la forma según el género
    new_form = pkmn.male? ? 1 : 0  # Forma 1 para macho (Galar), Forma 0 para hembra (normal)

    # Actualizar la forma y la especie tras la evolución
    pkmn.form = new_form
    pkmn.species = :MRMIME  # Cambiar la especie a Mr. Mime

    # Recalcular las estadísticas para reflejar los cambios de la evolución
    pkmn.calc_stats

    next true  # Continuar con la evolución
  }
)

Evolution screen code

class PokemonEvolutionScene
  def pbStartScreen(pokemon, newspecies)
    @pokemon = pokemon
    @newspecies = newspecies
    @sprites = {}
    @bgviewport = Viewport.new(0, 0, Graphics.width, Graphics.height)
    @bgviewport.z = 99999
    @viewport = Viewport.new(0, 0, Graphics.width, Graphics.height)
    @viewport.z = 99999
    @msgviewport = Viewport.new(0, 0, Graphics.width, Graphics.height)
    @msgviewport.z = 99999
    addBackgroundOrColoredPlane(@sprites, "background", "evolution_bg",
                                Color.new(248, 248, 248), @bgviewport)
    rsprite1 = PokemonSprite.new(@viewport)
    rsprite1.setOffset(PictureOrigin::CENTER)
    rsprite1.setPokemonBitmap(@pokemon, false)
    rsprite1.x = Graphics.width / 2
    rsprite1.y = (Graphics.height - 64) / 2
    rsprite2 = PokemonSprite.new(@viewport)
    rsprite2.setOffset(PictureOrigin::CENTER)
    
    # Comprobamos si Mime Jr. es macho y si evoluciona a Mr. Mime (Galar)
    if @pokemon.species == :MIMEJR && @pokemon.male? && @pokemon.hasMove?(:MIMIC)
      # Usar la forma Galar de Mr. Mime
      rsprite2.setPokemonBitmapSpecies(@pokemon, :MRMIME, true)  # Forma Galar
    else
      rsprite2.setPokemonBitmapSpecies(@pokemon, @newspecies, false)
    end
    
    rsprite2.x       = rsprite1.x
    rsprite2.y       = rsprite1.y
    rsprite2.visible = false
    @sprites["rsprite1"] = rsprite1
    @sprites["rsprite2"] = rsprite2
    @sprites["msgwindow"] = pbCreateMessageWindow(@msgviewport)
    set_up_animation
    pbFadeInAndShow(@sprites) { pbUpdate }
  end
end

I changed Evolution screen code, now mr mime's backsprite is showing.

okay, so what you are supposed to do is actually a bit different
you are supposed to change mime jr's form BEFORE any evolution, this makes things smooth

for an example, take a look at the rockruff code
