Forcing a trainer to use a specific last pokémon

[KillerMapper]

Hello !

I would like to know if it's possible to force a trainer (in my case, a gym leader, with better AI than regular trainers) to use a specific pokémon of his team as his last pokémon. I would like to have the strongest pokémon (which have custom IVs, movesets...) at the end of the battle, but the trainer will use it before the other (and less powerful) pokémons if the players use a strong pokémon.

Does PE have an option for that, or does it need some scripting anywhere ?

Thanks.

  def pbDefaultChooseNewEnemy(index,party)
    enemies=[]
    for i in 0..party.length-1
      if pbCanSwitchLax?(index,i,false)
        enemies.push(i)
      end
    end
    if enemies.length>0
      return pbChooseBestNewEnemy(index,party,enemies)
    end
    return -1
  end

with (XXX - your switch ID; this is untested)

  def pbDefaultChooseNewEnemy(index,party)
    enemies=[]
    length = party.length-1
    for i in 0..length
        if pbCanSwitchLax?(index,i,false)
            if i == length && $game_switches[xxx]
                if  enemies.length == 0
                    enemies.push(i)
                end
            else
                enemies.push(i)
            end

Thanks, it's working !

Do you think it's possible to let the trainer choose the best pokémon except for the last one ?

It actually does that. (It calls pbChooseBestNewEnemy)

If you are not satisfied with the criteria, you have to work with the function.

It is around line ~4000

  def pbChooseBestNewEnemy(index,party,enemies)
    return -1 if !enemies || enemies.length==0
    $PokemonTemp=PokemonTemp.new if !$PokemonTemp
    o1=@battlers[index].pbOpposing1
    o2=@battlers[index].pbOpposing2
    o1=nil if o1 && o1.isFainted?
    o2=nil if o2 && o2.isFainted?
    best=-1
    bestSum=0
    for e in enemies
      pkmn=party[e]
      sum=0
      for move in pkmn.moves
        next if move.id==0
        md=PBMoveData.new(move.id)
        next if md.basedamage==0
        if o1
          sum+=PBTypes.getCombinedEffectiveness(md.type,o1.type1,o1.type2)
        end
        if o2
          sum+=PBTypes.getCombinedEffectiveness(md.type,o2.type1,o2.type2)
        end
      end
      if best==-1 || sum>bestSum
        best=e
        bestSum=sum
      end
    end
    return best
  end

Things you could work around with:
-Pokemon base stats, expecting type damage
-Pokemon defensive capabilities (physical, spezial, KP)

"known" moves (this could be tricky, if you don't want to cheat)

I needed this to, I'm going to try it.
Also is there a way to get the opponent to show his sprite when he sends out said last Pokemon, just like it does in the games? Like for example when you face Galactic Boss Cyrus in Platinum, when he sends out his last Pokemon his sprite pops out for a second and he says, "I admit you have pushed me to this extreme."

Ok. Trainer just used the order defined in the txt, maybe I wasn't lucky. I'll try more battles then. Thanks for your help.

    return -1
  end

Sorry for asking.
How should i define the ID and how do I use it in the Event?
