Defining trainer Pokémon's EVs

I doubt anyone who knows what they're doing would have a hard time with this, but I'm led to believe this is harder than it looks so I'm going to post it anyway; it's quite possible I've forgotten something important.

Replace the set of definitions and first function at the top of "PTrainer_NPCTrainers" with this:

TPSPECIES   = 0
TPLEVEL     = 1
TPITEM      = 2
TPMOVE1     = 3
TPMOVE2     = 4
TPMOVE3     = 5
TPMOVE4     = 6
TPABILITY   = 7
TPGENDER    = 8
TPFORM      = 9
TPSHINY     = 10
TPNATURE    = 11
TPIV        = 12
TPHAPPINESS = 13
TPNAME      = 14
TPSHADOW    = 15
TPBALL      = 16
TPHPEV      = 17
TPATKEV     = 18
TPDEFEV     = 19
TPSPEEDEV   = 20
TPSATKEV    = 21
TPSDEFEV    = 22
TPDEFAULTS = [0,10,0,0,0,0,0,nil,nil,0,false,nil,10,70,nil,false,0,0,0,0,0,0,0]

def pbLoadTrainer(trainerid,trainername,partyid=0)

    if !hasConst?(PBTrainers,trainerid)
      raise _INTL("Trainer type does not exist ({1}, {2}, ID {3})",trainerid,trainername,partyid)
    end

  end
  success=false
  items=[]
  party=[]

  trainers=load_data("Data/trainers.dat")
  for trainer in trainers
    name=trainer[1]
    thistrainerid=trainer[0]
    thispartyid=trainer[4]
    next if trainerid!=thistrainerid || name!=trainername || partyid!=thispartyid
    items=trainer[2].clone
    name=pbGetMessageFromHash(MessageTypes::TrainerNames,name)
    for i in RIVALNAMES
      if isConst?(trainerid,PBTrainers,i[0]) && $game_variables[i[1]]!=0

      pokemon.setItem(poke[TPITEM])
      if poke[TPMOVE1]>0 || poke[TPMOVE2]>0 || poke[TPMOVE3]>0 || poke[TPMOVE4]>0
        k=0
        for move in [TPMOVE1,TPMOVE2,TPMOVE3,TPMOVE4]
          pokemon.moves[k]=PBMove.new(poke[move])
          k+=1

      party.push(pokemon)
    end
    success=true
    break
  end
  return success ? [opponent,items,party] : nil
end

These will allow you to give custom EV spreads to trainers. The EVs come after everything else, and in the usual order for Essentials (speed/satk/sdef), so you'd define a trainer's mon like this for a 252 Atk/Speed mon:

GYARADOS,50,CHOICEBAND,AQUATAIL,EARTHQUAKE,STONEEDGE,BOUNCE,0,F,,,ADAMANT,31,,kogasa,,,0,252,0,252,0,0

As with the other fields, you don't have to give every trainer's pokemon specially defined EVs, or even extend commas that far. They'll default to 0 in every EV instead of the weird inflated formula vanilla Essentials uses, though.

You picked up Pokemon Essentials less than 5 hours ago and this what you do with it.

Honestly I can't say I'm surprised, and I'm probably not the only one who's wanted to see a script like this for a long time now! I probably won't be adding it to Faith & Prayer Version (Unless I decide to rebalance the entire game), but I'm sure someone out there will want this.

 

[Telemetius]

This is going to take custom battles on a whole new level :D

 

[digitalkaiser65]

This is very interesting and helpful!
I'm looking to put something like this in my game, so I'm glad I found a post about it. I will def check it out once I get to that point!

Woo!

 

[TACHAN]

Great!!
I think you could do something similar with Ivs (for Gyro Ball, Trick Room teams and Hidden Power) the problem is to change all trainers in Trainers.txt to be compatible, unless you can do so:

GYARADOS,50,CHOICEBAND,AQUATAIL,EARTHQUAKE,STONEEDGE,BOUNCE,0,F,,,ADAMANT,31,,kogasa,,,0,252,0,252,0,0,[B]31,31,31,31,31[/B]

Leaving the first 31(or other number 0-31) like HP IV, while the five last 31(or other number 0-31) are Atk, Def, SATK, SDef, Speed
But I do not know what should be changed in the script

 

[Arkadious]

Hi :) Just wondering if this still works in Essentials 16.2
I keep getting interpreter errors whenever I try to start a trainer battle, regardless of whether the print version is used or not.

[Derxwna Kapsyla]

I added the script to 16.2 when updating my game, and so far everything's been working fine? It required a few reworking iirc but, that's a simple work of comparing changes between v16, v16.2, and the script
