[Scripting Question] How do I change the IVs of wild Pokemon encountered?

[DohnJoeOK]

Pretty much the title. I am on v20 and I want to change the IVs of all wild Pokemon to be 31 (as a test). How do I do it?

 

[Disccat]

Go to the "Overworld_EncounterModifiers" script, and add this just before the "random dungeon map" line.

EventHandlers.add(:on_wild_pokemon_created, :max_full_iv,
  proc { |pkmn|
  if $game_switches[XX]
    pkmn.iv[:HP] = 31
    pkmn.iv[:ATTACK] = 31
    pkmn.iv[:DEFENSE] = 31
    pkmn.iv[:SPECIAL_ATTACK] = 31
    pkmn.iv[:SPECIAL_DEFENSE] = 31
    pkmn.iv[:SPEED] = 31
  end
}
)

In the line "if $game_switches[XX]", replace XX by the number of the game switch you want to active before you fight the wilf Pokémon. Turn this switch off after the battle, or in case of defeat, turn it off in an event like the nurse in Pokémon Centers.
