Use Item on limited pokemon [solved]

[Zangofete]

Is it possible to create an item that you can only use on some species of pokemon, I want the item to do similar things as protein, iron, calcium ect But to be only work on certain pokemon such as starters.

I tried looking at stone evolution methods but upon compiling my script it kept breaking as im not sure where to put it.

I am trying to make it so the item Upgrade can only be used on Porygon, and for it to increase its base happiness as I want it to evolve through happiness.

UnderchangeHappiness among the other items i added in what i want upgrade to do.

when "Upgrade"
        gain=5
        gain=200 if @happiness<200

I think that is right.

And under ItemEffects I want something like this

ItemHandlers::UseOnPokemon.add(:UPGRADE,proc{|item,pokemon,scene|
  
  if pb.isSpecies(PORYGON) 
    scene.pbDisplay(_INTL("It won't have any effect."))
     next false
   else
     scene.pbDisplay(_INTL("{1} Seems to be growing at a very fast rate",pokemon.name))
     pokemon.changeHappiness("Upgrade")
     next true
   end
})

But i dont know the correct way to make it so its only Porygon can have this item used on it. This doesn't compile because if pb.isSpecies(PORYGON) is just my pseudo code I dont know how to check for the species.

Thank you mej!

ItemHandlers::UseOnPokemon.add(:UPGRADE,proc{|item,pokemon,scene|
   if pokemon.species != getID(PBSpecies,:PORYGON)
     scene.pbDisplay(_INTL("It won't have any effect."))
     next false
   else
      scene.pbDisplay(_INTL("{1} Seems to be growing at a very fast rate",pokemon.name))
      pokemon.changeHappiness("Upgrade")
      next true
     
   end
})

You're looking in the right place, it should be in PokemonItemEffects. Show us what you have and we can help you correct it.
