[Question] Help Coding Ability that reduce Priority before turn order calculation

[CodenameD]

I'm trying to program an ability that will treat all incoming increased priority moves as 0 priority, as long as the move is targeting the Pokemon with this ability.
So say if Kadabra has this ability, is faster and wants to use Signal Beam while Sneasel wants to use Sucker Punch or Quick Attack, Kadabra will use Signal Beam before Sucker Punch or Quick Attack.

I've tried this but it does not work as expected.

My Script:

BattleHandlers::PriorityChangeAbility.add(:SUDDENREFLEX,
  proc { |ability,battler,move,pri|
    if move.damagingMove?
      pri = 0 if pri > 0
    end
  }
)

Should I implement new ability handlers not part of Essentials code? Or can it be done upon existing codebase?

Unsure if this is the problem, but try adding "next" (without quotation marks) before

pri = 0 if pri > 0

so that you'd have

next pri = 0 if pri > 0

Didn't work. The problem appears to be, event handler is triggering for the Pokemon WITH the ability, not for the Pokemon OPPOSING the ability.
So move and pri belongs to Kadabra (the one with the ability), not Sneasel (the one who's priority should be reduced).

I need to trigger an event for a pokemon when facing a certain ability.

Sorry, I'll check back later because my PC is very good at finding problems it hadn't had

Edit: I have looked for a bit, but I have found nothing regarding the enemy pokémon's moves' priority. I'm afraid I can't help
