[Scripting Question] Dropped Items

[Manolloz]

I need a script so that when I defeat a Pokémon, it drops one or more pre-defined items for me in v17.
For example: when defeating a Caterpie, it would drop 0-5 "bug essences", and when defeating Butterfree, it would drop 2-10 "bug essences" + 1 Bug Wing.
In the case of new items that will be created, and in random quantity.
I found a script and made some modifications, but I think it's not exactly what I need:

### Wild pokemon drops item if defeated
  def pbDropItem (i)
    if rand(100)>50 && !@opponent
      $PokemonBag.pbStoreItem(:RandomItem)
      pbDisplay(_INTL("{1} dropped {2} from the pokemon!", $Trainer.name, PBItems.getName(RandomItem)))
      end
  end

Please, could you help me make this script?

Hi, I moved your thread here, to the Pokemon Essentials section.
This is the place to post your questions involving Pokemon Essentials itself.

You should mention which major version of essentials you are on. v17 and v18 have very different battle system code, to say the least!
