[Scripting Question] Own move effects

[Parritoso]

Hello everyone.
I need to create a move One-Hit K.O, which always hits, and also heals the pokemon from the state effects. I have created this code, from the K.O moves. But equal to failed, I think I have removed the part where I calculated the probability of failure. Have I done it or not? If anyone could tell me, thank you.

(This is my first script, surely this is very bad)

Spoiler:

class PokeBattle_Move_159 < PokeBattle_Move
  def pbAccuracyCheck(attacker,opponent)
    if !attacker.hasMoldBreaker && opponent.hasWorkingAbility(:STURDY)
      @battle.pbDisplay(_INTL("{1} was protected by {2}!",opponent.pbThis,PBAbilities.getName(opponent.ability)))  
      return false
    end
  end

  def pbEffect(attacker,opponent,hitnum=0,alltargets=nil,showanimation=true)
    damage=pbEffectFixedDamage(opponent.totalhp,attacker,opponent,hitnum,alltargets,showanimation)
    if opponent.fainted?
      @battle.pbDisplay(_INTL("It's a one-hit KO!"))
    end
    return damage
  end
  
  def pbEffect(attacker,opponent,hitnum=0,alltargets=nil,showanimation=true)
    if attacker.status!=PBStatuses::BURN &&
       attacker.status!=PBStatuses::POISON &&
       attacker.status!=PBStatuses::PARALYSIS
      @battle.pbDisplay(_INTL("But it failed!"))
      return -1
    else
      t=attacker.status
      attacker.pbCureStatus(false)
      pbShowAnimation(@id,attacker,nil,hitnum,alltargets,showanimation)
      if t==PBStatuses::BURN
        @battle.pbDisplay(_INTL("{1} healed its burn!",attacker.pbThis))  
      elsif t==PBStatuses::POISON
        @battle.pbDisplay(_INTL("{1} cured its poisoning!",attacker.pbThis))  
      elsif t==PBStatuses::PARALYSIS
        @battle.pbDisplay(_INTL("{1} cured its paralysis!",attacker.pbThis))  
      end
      return 0
    end
  end
end
