Quando lançaram Pokémon XY pro 3DS um novo tipo de troca foi colocado no jogo de Wonder Trade, onde não se sabe que pokémon vai se receber...
     Um exemplo seria: Você vai e coloca um Pikachu pra trocar mais você não sabe que Pokémon vai receber, você pode receber um Starly por exemplo, mais em raros casos pode se deparar com um Mewtwo, Rayquaza e uma Diancie.
     Porém o sistema é offline, ficticio...
     Aqui vai o Script...
     Funciona em qualquer versão do Pokémon Essentials.

Código:

=begin
*** Wonder Trade Script by Black Eternity ***
This script is to mimic Wonder Trade from an offline perspective.
THERE IS NO ONLINE CAPABILITIES OF THIS SCRIPT,
ALL CALCULATIONS ARE DONE INTERNALLY.

To call the script like normal and have ALL Pokemon trade-able, use the following.
    pbWondertrade(1,[],[])

Black listed Pokemon are to be added to the Exceptions arrays.
  Except is the list of pokemon the player is forbidden to trade.
    Here the player cannot trade any of the following.
      pbWonderTrade(1,[:PIKACHU,:SQUIRTLE,:CHARMANDER,;BULBASAUR],[])
   
  Except2 is the list of pokemon the player is forbidden to receive.
    Here the player cannot receive any of the following.
      pbWonderTrade(1,[],[:MEWTWO,;MEW,;DEOXYS])



The first parameter is the minimum allowed Level of the Pokemon to be traded.
For example, you can not trade a Pokemon through Wonder Trade unless its level
is greater than or equal to specified level.

    pbWonderTrade(40,[:SQUIRTLE,:CHARMANDER,:BULBASAUR],[:MEWTWO,:MEW,:DEOXYS])
    *** Only pokemon over level 40 can be traded, you cannot trade starters.
    *** You cannot receive these legendaries.
   
The fourth parameter, which has recently replaced mej71's "hardobtain"
is called "rare", this parameter developed also by mej71, will use
the Pokemon's rareness and filter the results depending on its values.

** Rareness is turned on by default, if you wish to disable it, call the
    function accordingly.
   
    pbWonderTrade(10,[:SQUIRTLE],[:CHARMANDER,:BULBASAUR],false)
    ** Only Pokemon over level 10, cannot trade Squirtle, cannot
    ** recieve Charmander or Bulbasaur, Rareness disabled.

It is up to you to use it how you wish, credits will be appreciated.

     ________________________________________________________________________


        No começo do Script você pode  ver o seguinte código...
"

Código:

pbWonderTrade(1,[:PIKACHU,:SQUIRTLE,:CHARMANDER,;BULBASAUR],[])

        Esses Pokémon se não me enganam não podem ser trocados, mais você pode mudar isso...
        Depois disso pode ver algo assim...

Código:

pbWonderTrade(1,[],[:MEWTWO,;MEW,;DEOXYS])

 
        Esses Pokémon são os que você raramente conseguira somente se você for mesmo sortudo pois a chance de conseguilos é de apenas 3 em 43210 mais você também pode mudar esses Pokémon.

        Espero ter ajudado...
        Em breve trarei novos tutoriais de Pokémon Essentials...
