[Scripting Question] HM Moves As held items

Nasuthan · Apr 1, 2021

Working with pokemon essentials v18 .1

In my game you need to be able to use the stock hm moves as is, Cut, Surf,Fly,Rocksmash however when you get to a certain point in the game based on the number of badges, an npc "the charm speccialist" will offer to make a charm for you, eg: Cut Charm, Surf Charm, Fly Charm, Rock Smash Charm. I've got this all set out already as an event. essentially the pokemon will be able to use the hm move in the field (not in battle) without losing a move slot. in my game pokemon can forget HM moves so these can be frgotten once youve progressed enough into the game to acquire the charms.

so the question becomes, how to alter the field moves script to allow for checking for an held item as well as continue to check if the Pokemon has the move.

eg:
if pokemon has the item and can learn the move related to the item but does not have the move allow it to use move in the overworld.
else check it has the move and use it.

I've tried to add this myself but keep getting errors.

I've tried to add the check using:- pkmn.hasItem?(:CUTCHARM) and it just doesnt do anything.

Any help or a point to somthing else that can help is welcome, I will just ask peopel to remember to be nice as I've gotten "snotty" replies off people because they now how to do somthing and think it should be obvious how to do it. remember that is always the case for everyone.

thanks in advance for any replies.

I feel like this would be way simpler to edit how the current 'Fly, Rock Smash' are activated. e.g. When we select a Pokemon within the Pokemon Party Screen, it'll show options "Summary, Held Item, etc" , how does it do this? This is what I think you should edit.

Then all you have to do, is add an 'or' operator to whatever condition it is right now. That condition is probably simple like "Does it currently know the move Fly?" if so show Fly option.

Now we know where we want to edit, but we don't know one of the reference 'new condition' yet besides 'held item', we also need to check if the selected PKMN can learn fly. So now navigate to how 'TM and HM works'. and try to find out how TM and HM determines if a PKMN can learn that move. edit#1 (there shouldn't be any PKMN that can naturally learn Fly through leveling and not being able to learn Fly through HM, although if there is, this method won't pick that up. For those special pokemons since the numbers are so low, you'd just add the "or if specie = _____" )

Currently, the game 'Fly' option is likely "If PKMN has Fly in its current move list, show option Fly" you'll need to add "or (if PKMN is holding held item = Fly Charm AND PKMN can learn Fly)

I haven't looked at the code to see how the element reference one another, but using this logic with your skills, you'd likely be able to get it done.

not really sure how to do it still, the only thing I'v found is this:

elsif pbCanUseHiddenMove?(pkmn,pkmn.moves.id)
if pbConfirmUseHiddenMove(pkmn,pkmn.moves.id)
@scene.pbEndScene
if isConst?(pkmn.moves.id,PBMoves,:FLY)
scene = PokemonRegionMap_Scene.new(-1,false)
screen = PokemonRegionMapScreen.new(scene)
ret = screen.pbStartFlyScreen

this is calling the fuctions which i wasnt able to add the pkmn.hasItem?(:CUTCHARM) check to.
wouldnt i still then have to call the move handlers in wich case theyd return false as the pokemon wouldnt have the move in its current moves.

anyone who can tell me what im doing wrong would be great, prepare for very janky code.

def pbCut
move = getID(PBMoves,:CUT)
movefinder = pbCheckMove(move)
heldItem = pbCheckHeldItem(:CUTITEM)
canUse = pbCheckCanLearnMove(move)
pokeName = pbGetName(move)
if heldItem == true
if canUse == true
if !pbCheckHiddenMoveBadge(BADGE_FOR_CUT,false) || (!$DEBUG)
pbMessage(_INTL("This tree looks like it can be cut down."))
return false
end
pbMessage(_INTL("This tree looks like it can be cut down!\1"))
if pbConfirmMessage(_INTL("Would you like to cut it?"))
speciesname = (PokeName) ? PokeName.name : $Trainer.name
pbMessage(_INTL("{1} used {2}!",speciesname,PBMoves.getName(move)))
pbHiddenMoveAnimation(movefinder)
return true
end
end
end

I don't really follow your code, but I feel like you're making this far more complicated than it needs to be. I was able to get what you're attempting to make working by simply doing this:

Paste this somewhere in PSystem_PokemonUtilities

Code:

def pbCheckHeldItem(item)
  item = getID(PBItems,item)
  return nil if !item || item<=0
  for i in $Trainer.pokemonParty
    return i if i.item==item
  end
  return nil
end

Then in pbCut, change the line movefinder = pbCheckMove(move) to this instead:

Code:

movefinder = (pbCheckMove(move) || pbCheckHeldItem(:CUTCHARM))

That's it.

Obviously, replace CUTCHARM with whatever your item is, and then just replicate this for each field move.

When used in the field, the game will prioritize Pokemon in the party that have the move Cut, but if none exist, it will then check for Pokemon with the Cut Charm instead.

I alredy have this in pokemon utilites def pbCheckHeldItem(item) yours looks more elegent for sure but also mine works. so im going with if it isnt broke dont fix it.

I did manage to get it working for CUT, ROCK SMASH,DIVE,SURF with the code I had but my problem is FLY,

like I mentioned I dont want just any pokemon to hold the charm and be able to use its respective move. so i do a check if the pokemon can learn a move pbcheck move only return if the pokemon has the move which would make the charm pointless.

I need to be able to give a pokemon the fly charm and have fly appear in the party menu for the pokemon if they can use the move fly but dont have it. also for quickness to be able to press tab and have the fly option with the same peramiters eg: if pokemon has held item and can learn fly then use fly elseIf pokemon knows fly then use fly

any hints would be fab

Oh, if you want the move to appear in the party menu while holding the item, then that's a whole different story and will require a bunch of edits in the Party screen. I've done this before when adding new party commands when creating the Birthsign script.

Off the top of my head, you'll have to find the line

Code:

cmdMoves   = [-1,-1,-1,-1]

And then add an entry for each field move you're attempting to add via held item. So for example

Code:

cmdCut      = -1
cmdStrength = -1
cmdSurf     = -1

Etc, etc...

Then, you'll have to add the command text for each entry a few lines down, above this:

Code:

commands[cmdSwitch = commands.length]       = _INTL("Switch") if @party.length>1

Each of your entries should look something like this:

Code:

commands[cmdCut = commands.length]       = [_INTL("Cut"),1] if pkmn.hasItem?(:CUTCHARM)

Then further down still, you'll have to add what each of these new commands do when selected, above this:

Code:

elsif cmdMail>=0 && command==cmdMail

Each of your entries should look something like this:

Code:

elsif cmdCut>=0 && command==cmdCut
        move = getID(PBMoves,:CUT)
        if pbCanUseHiddenMove?(pkmn,move)
          if pbConfirmUseHiddenMove(pkmn,move)
            @scene.pbEndScene
            return [pkmn,move]
          end
        end

For Fly in particular, you'll need a completely different code:

Code:

elsif cmdFly>=0 && command==cmdFly
        move = getID(PBMoves,:FLY)
        if pbCanUseHiddenMove?(pkmn,move)
          if pbConfirmUseHiddenMove(pkmn,move)
            @scene.pbEndScene
            scene = PokemonRegionMap_Scene.new(-1,false)
            screen = PokemonRegionMapScreen.new(scene)
            ret = screen.pbStartFlyScreen
            if ret
              $PokemonTemp.flydata=ret
              return [pkmn,move]
            end
          end
        end

And that *should* do it. Any of the code you implemented in PField_FieldMoves should no longer be necessary after this, because for all intents and purposes the Pokemon will just be treated as if it has that field move while the item is held.

Idk, I've never used that menu or even looked at that code tbh.

I tested last night the changes to add the fly to the party screen pokemon commands and you can fly but if you click cancel without chosing a fly location and retun to pause menu i get this error

Nasuthan · Apr 2, 2021

figured it out was missing a line to start the party screen menu

elsif cmdFly>=0 && command==cmdFly
move = getID(PBMoves,:FLY)
if pbCanUseHiddenMove?(pkmn,move)
if pbConfirmUseHiddenMove(pkmn,move)
@scene.pbEndScene
scene = PokemonRegionMap_Scene.new(-1,false)
screen = PokemonRegionMapScreen.new(scene)
ret = screen.pbStartFlyScreen
if ret
$PokemonTemp.flydata=ret
return [pkmn,move]
end
##### missing line
@scene.pbStartScene(@party,
(@party.length>1) ? _INTL("Choose a Pokémon.") : _INTL("Choose Pokémon or cancel."))
end
