Pokemon Yellow Pikachu only following and cant evolve script ?

[oldsnake90]

i'm wanna make a Pokemon yellow easter egg where if you pick Pikachu it would follow you and wont evolve. but i want that the only one to follow me. and i want it to follow me even if its not party leader. what should i do?
i like something like the pokemon following script but thats only for the party leader

Just use pbAddDependency2(eventID, eventName, commonEvent) within the event for Pikachu, simple... Assuming you cannot capture Pikachu in your game, just edit the PBS file so Pikachu doesn't evolve... Or, add the red line:

def pbCheckEvolutionEx(pokemon)
  return -1 if pokemon.species<=0 || pokemon.egg?
  return -1 if isConst?(pokemon.species,PBSpecies,:PICHU) && pokemon.form==1
  [COLOR="Red"]return -1 if isConst?(pokemon.species,PBSpecies,:PIKACHU)[/COLOR]
  return -1 if isConst?(pokemon.item,PBItems,:EVERSTONE)
  ret=-1
  for form in pbGetEvolvedFormData(pokemon.species)
    ret=yield pokemon,form[0],form[1],form[2]
    break if ret>0
  end
  return ret
end

This will allow both, following and non-evolution... Providing you know how to use dependencies.
