[Scripting Question] Trigger Held Items (Max Ether, Elixir, Max Elixir, Full Restore)

[Ecrur]

Hello everybody!
I am trying to make some items that when held give the same effect of "man-made" medicines (like potions, ethers, antidotes, etc...).
With most of them I had no problem since I just copied the script of the corresponding berries, but I'm having a few problems with the trigger and the effect of max ether, elixir, max elixir and full restore because I am really ignorant script-wise.
Could anybody help me? I guess the easiest way is to start from the leppa berry script in the PokeBattle_Battler section but then how should I modify the script to obtain the effect I am looking for?

elsif isConst?(berry,PBItems,:NEWITEM)
      found=[]
      for i in [email protected]
        if @pokemon.moves[i].id!=0
          if (consume && @pokemon.moves[i].pp==0) ||
             (!consume && @pokemon.moves[i].pp<@pokemon.moves[i].totalpp)
            found.push(i)
          end
        end
      end
      if found.length>0
        choice=(consume) ? found[0] : found[@battle.pbRandom(found.length)]
        [email protected][choice]
        pokemove.pp+=10
        pokemove.pp=pokemove.totalpp if pokemove.pp>pokemove.totalpp 
        self.moves[choice].pp=pokemove.pp
        movename=PBMoves.getName(pokemove.id)
        @battle.pbDisplay(_INTL("{1}'s {2} restored {3}'s PP!",pbThis,berryname,movename)) 
        consumed=true
      end

Thank you in advance if anyone can help me and stay safe!
