FL do you think you could make a tutorial for essentials v17 as the structure of the code is a bit different and its quite confusing to me and im guessing thats the same for others as well

Hello. I have the Same Problem as @TheTangentYeti.
Since the Structure of the Code changed in 17.2 I have no Idea what to change so I can make an Item out of a HM.
Yes, the Code might still work with 17.2 but the Thing is, that @MissKanabelle used it with SURF. I need it for CUT. Both codes look very different to me. Another thing is that I am very new to RPGMaker and Pokémon essentials and I learned that I should not edit the code, if I do not fully understand what it does.
I think what would help me as a completly noob besides Video tutorials, is if someone could tell me exactly what lines I have to change to what. For example: The Code of CUT starts at line 192 and ends with
247.So If someone could for example say: Change Line 209

Code:

HiddenMoveHandlers::CanUseMove.add(:CUT,proc{|move,pkmn,showmsg|

to

Code:

HiddenMoveHandlers::CanUseMove.add(:CUT,proc{|CHANGE,FOR,EXAMPLE|

I could better understand what happend and what was changed. Or post an example code of the code I need so I can check what was changed and where. That would be a great help.

Hey thanks so much for all your guides and tutorials! They've been super helpful.

I can't seem to get my HM Item Strength to work however.
I can interact with the builders fine and the game recognizes the HM item I think, but when I activate the item, I just can't move the boulder. The boulder won't budge.

This is my Strength script... sorry for messy format!

def Kernel.pbStrength
if $DEBUG ||
(HIDDENMOVESCOUNTBADGES ? $Trainer.numbadges>=BADGEFORCUT : $Trainer.badges[BADGEFORCUT])
movefinder=Kernel.pbCheckMove(:STRENGTH)
movefinder=nil
if $DEBUG || $PokemonBag.pbQuantity(PBItems::EXO)>0
if Kernel.pbConfirmMessage(_INTL("Would you like to equip the Exoskeleton and move the boulder?"))
speciesname=!movefinder ? $Trainer.name : movefinder.name
Kernel.pbMessage(_INTL("{1} equipped the Exoskeleton!",$Trainer.name))
pbHiddenMoveAnimation(movefinder)
return true
end
else
Kernel.pbMessage(_INTL("It's a big boulder, but theoretically it should be movable."))
end
else
Kernel.pbMessage(_INTL("It's a big boulder, but theoretically it should be movable."))
end
return false
end

Events.onAction+=proc{|sender,e|
facingEvent=$game_player.pbFacingEvent
if facingEvent
if facingEvent.name=="Boulder"
Kernel.pbStrength
return
end
end

# return false if !pbCheckHiddenMoveBadge(BADGEFORSTRENGTH,showmsg)

# return false
# end
# return true
#})

#HiddenMoveHandlers::UseMove.add(:STRENGTH,proc{|move,pokemon|

Yo FL! It worked like a charm haha thanks a bunch. It's been really cool to try and make my own Pokemon game, and it's a lot due to you haha!

Sorry if I'm asking too much, but do you mind sharing your Fly or Waterfall scripts? Haha thanks again!

First, in PokemonHiddenMoves script section comment the 'HiddenMoveHandlers::CanUseMove' proc (all the code, inclusive the '})'). Change the line '(!$DEBUG && !movefinder)' (there's one for each move that can be used outside menu) to '(!$DEBUG && $PokemonBag.pbQuantity(PBItems::YOURITEMINTERNALNAME)==0)'. Before line 'speciesname = (movefinder) ? movefinder.name : $Trainer.name', add line 'movefinder=nil' for won't show pokémon name and animation. There's a item example for item.txt PBS:

Code:

601,SURFBOARD,Surfboard,Surfboards,8,0,"Insert description here.",0,0,6

Mark HIDDENMOVESCOUNTBADGES as true and all badges to 0 to remove the badge requirements.

I dont want to make you guys feel like u wasted your time...
But Marin made a perfectly functioning script called HMItems that can be added using Luka S.J.'s EPI...
