[Scripting Question] Help with a custom ability

[aitsuki]

Hi there! Thanks for taking the time to read this post in advance! I saw this really neat ability from the fangame Pokemon Azurite and would greatly appreciate if someone could suggest how to code them in Essentials.

Voodoo: Any damage that the user receives will also be received by Pokemon on the field that share the same egg group as it.

I'm very new to Essentials so if someone could help me out, I'd really apperciate it!

well, I also love interesting coding problems, so here we go, v19 code. It was similar to Innards Out so I used that as reference.
Ditto does not count as every type, and would only match with Ditto.

This will hit any pokemon on the field, friend or foe.

BattleHandlers::TargetAbilityOnHit.add(:VOODOO,
  proc { |ability,user,target,move,battle|
    next if !target.fainted?
    battle.pbShowAbilitySplash(target)
    target_egg_group = target.pokemon.species_data.egg_groups
    battle.battlers.each do |b|
      next if !b
      next if b.fainted?
      next if b.index!=target.index
      b_egg_group = b.pokemon.species_data.egg_groups
      next if (target_egg_group & b_egg_group).length == 0
      b.pbReduceHP(target.damageState.hpLost,false)
      if PokeBattle_SceneConstants::USE_ABILITY_SPLASH
        battle.pbDisplay(_INTL("{1} is hurt!",b.pbThis))
      else
        battle.pbDisplay(_INTL("{1} is hurt by {2}'s {3}!",b.pbThis,
           target.pbThis(true),target.abilityName))
      end
    end
    battle.pbHideAbilitySplash(target)
  }
)

This will only hit foes

BattleHandlers::TargetAbilityOnHit.add(:VOODOO,
  proc { |ability,user,target,move,battle|
    next if !target.fainted?
    battle.pbShowAbilitySplash(target)
    target_egg_group = target.pokemon.species_data.egg_groups
    target.eachOpposing do |b|
      b_egg_group = b.pokemon.species_data.egg_groups
      next if (target_egg_group & b_egg_group).length == 0
      b.pbReduceHP(target.damageState.hpLost,false)
      if PokeBattle_SceneConstants::USE_ABILITY_SPLASH
        battle.pbDisplay(_INTL("{1} is hurt!",b.pbThis))
      else
        battle.pbDisplay(_INTL("{1} is hurt by {2}'s {3}!",b.pbThis,
           target.pbThis(true),target.abilityName))
      end
    end
    battle.pbHideAbilitySplash(target)
  }
)
