[Scripting Question] Rock Smash HM item field animation not working?

[Torterraman]

This is in essentials V 17.2

I currently have a working script for a rock smash field item. The animation works fine when I just walk up to the rock and trigger the event like that, but whenever I stand next to the rock facing the rock, open the menu and use the item from there, it does not play the animation. The rock still breaks, the text still pops up saying I used rock smash, and the sound still happens, but the rock just vanishes without blowing up.

Here is the code from the rock smash section in PField_Moves
I have certain parts of it commented out in order to make the item work correctly.

def pbRockSmashRandomEncounter
  if rand(100)<25
    pbEncounter(EncounterTypes::RockSmash)
  end
end

def Kernel.pbRockSmash
  move = getID(PBMoves,:ROCKSMASH)
  movefinder = nil
  movefinder = Kernel.pbCheckMove(move)
  if $PokemonBag.pbQuantity(PBItems::POKEASSISTROCKSMASH)==0
    Kernel.pbMessage(_INTL("It's a rugged rock, but a Pokémon may be able to smash it."))
    return false
  else 
    if Kernel.pbConfirmMessage(_INTL("This rock appears to be breakable. Would you like to use Rock Smash?"))
       movefinder = nil
       speciesname = (movefinder) ? movefinder.name : $Trainer.name
       Kernel.pbMessage(_INTL("{1} used {2}!",speciesname,PBMoves.getName(move)))
       pbHiddenMoveAnimation(movefinder)
       return true
    end
  end
end

#HiddenMoveHandlers::CanUseMove.add(:ROCKSMASH,proc{|move,pkmn,showmsg|
#   return false if !pbCheckHiddenMoveBadge(BADGEFORROCKSMASH,showmsg)
#   facingEvent = $game_player.pbFacingEvent
#   if !facingEvent || facingEvent.name!="Rock"
#     Kernel.pbMessage(_INTL("Can't use that here.")) if showmsg
#     return false
#   end
#   return true
#})

#HiddenMoveHandlers::UseMove.add(:ROCKSMASH,proc{|move,pokemon|
#   if !pbHiddenMoveAnimation(pokemon)
#     Kernel.pbMessage(_INTL("{1} used {2}!",pokemon.name,PBMoves.getName(move)))
#   end
#   facingEvent = $game_player.pbFacingEvent
#   if facingEvent
#     pbSmashEvent(facingEvent)
#     pbRockSmashRandomEncounter
#   end
#   return true
#})

def canUseMoveRockSmash?
   showmsg = true
   facingEvent = $game_player.pbFacingEvent
   if !facingEvent || facingEvent.name!="Rock"
     Kernel.pbMessage(_INTL("Can't use that here.")) if showmsg
     return false
   end
   return true
end

def useMoveRockSmash
   if !pbHiddenMoveAnimation(nil)
     Kernel.pbMessage(_INTL("{1} used {2}!",$Trainer.name,"Rock Smash"))
   end
   facingEvent = $game_player.pbFacingEvent
   if facingEvent
     pbSmashEvent(facingEvent)
   end
   return true
end

Here is the code from the item effects section.

ItemHandlers::UseFromBag.add(:POKEASSISTROCKSMASH,proc{|item|
   next canUseMoveRockSmash? ? 2 : 0
})

ItemHandlers::UseInField.add(:POKEASSISTROCKSMASH,proc{|item|
   useMoveRockSmash if canUseMoveRockSmash?
})

Any help is greatly appreciated! Thanks!
