[Scripting Question] Creating a Special Defense Variant of Psyshock

[Tommaniacal]

Hello, I'm attempting to create a physical move that uses the target's special defense, effectively a reverse of Psyshock.

Here's its info in moves.txt:
690,SOULSTRIKE,Soul Strike,D0D,80,GHOST,Physical,100,10,10,00,0,abef,"The user attacks through to the target's very soul. This attack does special damage."

In Pokebattle_Move, I changed:

    defense=opponent.defense
    defstage=opponent.stages[PBStats::DEFENSE]+6
    # TODO: Wonder Room should apply around here
    applysandstorm=false

to:

    if type>=0 && pbIsPhysical?(type) && @function!=0xD0D # Soul Strike
      defense=opponent.defense
      defstage=opponent.stages[PBStats::DEFENSE]+6
      applysandstorm=false
    end

and in Pokebattle_MoveEffects:

################################################################################
# Target's Special Defense is used instead of its Defense for this move's
# calculations. (Soul Strike)
################################################################################
class PokeBattle_Move_D0D < PokeBattle_Move
# Handled in superclass def pbCalcDamage, do not edit!
end

However, I now receive this error when attempting to use any physical move:

I tried to use the same format special defense and psyshock used, but I must have messed up somewhere. Any help would be greatly appreciated!

I'm getting the same error, and I even added the code to PokeBattle_AI. Can anyone help us? I was planning to add two Ghost moves named Shadow Shock and Shadow Strike (though Spirit Shock and Spirit Strike are good alternatives.)

This is how it worked for me:
Right in PokeBattle_Move under

    # TODO: Wonder Room should apply around here
    applysandstorm=false

I did this where 178 is the number of the new move in your case it should be 0xD0D:

    if type>=0 && (pbIsSpecial?(type) || @function==0x178) && @function!=0x122 # Psyshock
      defense=opponent.spdef
      defstage=opponent.stages[PBStats::SPDEF]+6
      applysandstorm=true
    end

Thank you! This worked for me.

Going off of AmineFifty's code, I changed the script in Pokebattle_AI to:

    # Get base defense stat
    defense=pbRoughStat(opponent,PBStats::DEFENSE,skill)
    applysandstorm=false
    if type>=0 && move.pbIsSpecial?(type) [COLOR="Red"]|| move.function==0xD0D # Soul Strike[/COLOR]
      if move.function!=0x122 # Psyshock
        defense=pbRoughStat(opponent,PBStats::SPDEF,skill)
        applysandstorm=true
      end
    end

I forgot to copy what the script was before editing, but it no longer returns an error so I'm hoping it works lol.
