Mashirosakura · Feb 9, 2017

Well I tried and it causes another error. Unless I did something stupid.

You're missing an end for your if

Code:

if $PokemonGlobal.flashUsed
  Kernel.pbMessage(_INTL("This is already in use"))
  return false
[COLOR="Red"]end[/COLOR]
return true

It worked! Thanks very much :)

EDIT: I just realised this code is just the base code for flash...and that doesn't help for me actually turning it into an item.

Mashirosakura · Mar 2, 2017

Ok, as I see my previous edit didn't really get an answer, I'll double-post (though I don't want to).
So what I got given when I asked for help getting an alternative (in item form) for Flash was the base code for it. I must have been misunderstood then so I'm clearing it up. Now, can anyone help me with the code for a working Flash item?

I tested right now and the method is equals to Cut one. It's even easier, since Flash can't be used outside menu.

The code:

Code:

605,LANTERN,Lantern,Lanterns,8,0,"A lantern that illuminate caves.",2,0,6

I copied the two HiddenMoveHandlers below (these are in base Essentials):

Code:

HiddenMoveHandlers::CanUseMove.add(:FLASH,proc{|move,pkmn|
   if !$DEBUG &&
      !(HIDDENMOVESCOUNTBADGES ? $Trainer.numbadges>=BADGEFORFLASH : $Trainer.badges[BADGEFORFLASH])
     Kernel.pbMessage(_INTL("Sorry, a new Badge is required."))
     return false
   end
   if !pbGetMetadata($game_map.map_id,MetadataDarkMap)
     Kernel.pbMessage(_INTL("Can't use that here."))
     return false
   end
   if $PokemonGlobal.flashUsed
     Kernel.pbMessage(_INTL("This is in use already."))
     return false
   end
   return true
})

HiddenMoveHandlers::UseMove.add(:FLASH,proc{|move,pokemon|
   darkness=$PokemonTemp.darknessSprite
   return false if !darkness || darkness.disposed?
   if !pbHiddenMoveAnimation(pokemon)
     Kernel.pbMessage(_INTL("{1} used {2}!",pokemon.name,PBMoves.getName(move)))
   end
   $PokemonGlobal.flashUsed=true
   while darkness.radius<176
     Graphics.update
     Input.update
     pbUpdateSceneMap
     darkness.radius+=4
   end
   return true
})

For making the two methods below. I added after the handlers:

Code:

def canUseMoveFlash?
  if !$DEBUG &&
    !(HIDDENMOVESCOUNTBADGES ? $Trainer.numbadges>=BADGEFORFLASH : $Trainer.badges[BADGEFORFLASH])
    Kernel.pbMessage(_INTL("Sorry, a new Badge is required."))
    return false
  end
  if !pbGetMetadata($game_map.map_id,MetadataDarkMap)
    Kernel.pbMessage(_INTL("Can't use that here."))
    return false
  end
  if $PokemonGlobal.flashUsed
    Kernel.pbMessage(_INTL("This is in use already."))
    return false
  end
  return true
end
 
def useMoveFlash
  darkness=$PokemonTemp.darknessSprite
  return false if !darkness || darkness.disposed?
  if !pbHiddenMoveAnimation(nil)
    Kernel.pbMessage(_INTL("{1} used {2}!",$Trainer.name,"Flash"))
  end
  $PokemonGlobal.flashUsed=true
  while darkness.radius<176
    Graphics.update
    Input.update
    pbUpdateSceneMap
    darkness.radius+=4
  end
  return true
end

And I added at PokemonItemEffects script section:

Code:

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

ItemHandlers::UseInField.add(:LANTERN,proc{|item|
   useMoveFlash if canUseMoveFlash?
})

Thanks very much, it's 100% working! :)
Whilst we're still on the subject, I've tried out your surf one and it no longer works, something about pbIsWaterTag?

Did you tried the described on latest posts?

Yes, I did. Here, this is a clearer way of me showing you the issue.

Try the Vernerl code (with the commented changes).

I used that code and I got the error I posted before. pbWaterTag isn't being found.

I read the codes again and you was right. Changing 'pbIsWaterTag?(terrain)' to 'PBTerrain.isSurfable?(terrain)' should fix these problems.

It fixed the initial activating surf animation issue. Now a new one has started, when I move in any direction in the water afterwards. I'll put an image below.

Look at the error. Please. "isSurfableTag?".

Hasn't fixed anything, sadly. I put it where the error was but there's still an issue.

I tested my tutorial again on V 16.2, even on bridges. The working code:

Code:

def canUseMoveSurf?
  if !$DEBUG &&
     !(HIDDENMOVESCOUNTBADGES ? $Trainer.numbadges>=BADGEFORSURF : $Trainer.badges[BADGEFORSURF])
    Kernel.pbMessage(_INTL("Sorry, a new Badge is required."))
    return false
  end
  if $PokemonGlobal.surfing
    Kernel.pbMessage(_INTL("You're already surfing."))
    return false
  end
  if $game_player.pbHasDependentEvents?
    Kernel.pbMessage(_INTL("It can't be used when you have someone with you."))
    return false
  end
  if pbGetMetadata($game_map.map_id,MetadataBicycleAlways)
    Kernel.pbMessage(_INTL("Let's enjoy cycling!"))
    return false
  end
  terrain=Kernel.pbFacingTerrainTag
  notCliff=$game_map.passable?($game_player.x,$game_player.y,$game_player.direction)
  if !PBTerrain.isSurfable?(terrain) || !notCliff
    Kernel.pbMessage(_INTL("No surfing here!"))
    return false
  end
  return true
end
 
def useMoveSurf
  $game_temp.in_menu=false
  if !pbHiddenMoveAnimation(nil)
    Kernel.pbMessage(_INTL("{1} used Surfboard!",$Trainer.name))
  end
  surfbgm=pbGetMetadata(0,MetadataSurfBGM)
  pbCueBGM(surfbgm,0.5) if surfbgm
  pbStartSurfing()
  return true
end

It must be something on my end then, because I'm still getting the error with PBEndSurf

and my item is defined as:

Hi, could I get a little help with my surf code? I am trying to replace the HM with a surfboard item which works up until I try to actually surf then it throws out this error:

end
return false
end

Events.onAction+=proc{|sender,e|
terrain=Kernel.pbFacingTerrainTag
notCliff=$game_map.passable?($game_player.x,$game_player.y,$game_player.direction)
if PBTerrain.isSurfable?(terrain) && !$PokemonGlobal.surfing &&

}

def canUseMoveSurf?

    return false
  end
  if pbGetMetadata($game_map.map_id,MetadataBicycleAlways)

    return false
  end
  terrain=Kernel.pbFacingTerrainTag

  return true
end

if !pbHiddenMoveAnimation(pokemon)
Kernel.pbMessage(_INTL("{1} used {2}!",pokemon.name,PBMoves.getName(move)))
end
pbStartSurfing()
return true
})

And this is what I have for the effects

Code:

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

ItemHandlers::UseInField.add(:SURFBOARD,proc{|item|
   useMoveSurf if canUseMoveSurf?
})

I have it defined in the items like this:
527,SURFBOARD,Surfboard,Surfboards,8,0,"This Surfboard is used to travel across the water.",2,0,6
