[Scripting Question] Mega Evolutions from Alternate Forms

AaronPendragon · Apr 9, 2018

I saw a similar thread to this one several pages back, but it was in regards to v16, whereas I'm on 17. Currently trying to figure out how to have several different forms of the same species (mostly recolors) each evolve into their own corresponding megas. The pbs doesn't appear to allow for it - just for when it turns unmega. Spent all day searching for answers and this is me giving up and asking for help. Anyone, please? If my explanation is hard to understand, just assume I'd like to make separate mega evolutions for Alolan and Kantonian Ninetales or something. Just need to know how to script that and would like to avoid splitting their Pokédex numbers at all costs. Thanks for your time!

What you can do is have different mega stones (like with Charizard and Mewtwo) for the two different mega forms. In your case it would be a Ninetalesinite and an Alolan Ninetalesinite (abbreviate if you like). The PBS code would be as follows:

Code:

#-------------------------------
[NINETALES-2]
FormName=Mega Ninetales
MegaStone=NINETALESINITE
UnmegaForm=0
#-------------------------------
[NINETALES-3]
FormName=Mega Alolan Ninetales
MegaStone=ALOLANNINETALESINITE
UnmegaForm=1

The FormName is only needed if you want the mega forms to appear in the Pokédex. Stats, abilities, types, etc are defined in the PBS file like every other alternate form.

EDIT: There may still be a potential bug where one form has the other form's mega stone attached.

Hey, thanks for the reply! But yeah, that's what I'm stuck on, actually. I tried exactly that with two different mega forms of Pidgeot. Now I need a way to make sure that only the intended form of that species can evolve into its corresponding mega. Seems like there has to be a way to either do that, or have, for example, form 2 mega evolve into form 5. Or if it's simpler, form 1 into form 11, 3 into 13, etc.
I don't care whether or not I have to make a stone for every version of every mega, as long as it works, ya know?

James Davy · Apr 11, 2018

I may have a way to pull this off. It will involve creating a function checking mega stones against the species' form:

Code:

class PokeBattle_Pokemon
  def getMegaForm(itemonly=false)
    formdata = pbLoadFormsData
    return 0 if !formdata[@species] || formdata[@species].length==0
    ret = 0
    dexdata = pbOpenDexData
    for i in formdata[@species]
      next if !i || i<=0
      pbDexDataOffset(dexdata,i,29)
      megastone = dexdata.fgetw
      if megastone>0 && self.hasItem?(megastone) [COLOR="red"]&& formMatches?(megastone)[/COLOR]
        ret = i; break
      end
      if !itemonly
        pbDexDataOffset(dexdata,i,56)
        megamove = dexdata.fgetw
        if megamove>0 && self.hasMove?(megamove)
          ret = i; break
        end
      end
    end
    dexdata.close
    return ret  # fSpecies or 0
  end

  [COLOR="red"]def formMatches?(megastone)
    case @species
    when PBSpecies::NINETALES
      case @form
      when 0
        return true if isConst?(megastone,PBItems,:NINETALESINITE)
        return false
      when 1
        return true if isConst?(megastone,PBItems,:ALOLANNINETALESINITE)
        return false
      end
    else
      return true if megastone>0 && self.hasItem?(megastone)
      return false
    end
  end[/COLOR]

That worked! Thank you very much. I?ll go with that as a backup plan if necessary, but I was hoping for a way to make a certain one of a Pokemon?s form numbers line up with another one by using the same mega stone. Since nearly every species is going to have at least two alternate color forms, that would probably be easier in the end.

I was thinking of having the script force form 1 to M Evo to form 11, 2 to 12, etc. OR set up a line in pokemonforms.txt called MegaForm to basically serve as a reverse of the existing Unmega line. I?ve been playing with both possibilities and have learned a lot about the script in the process, but it?s got me stumped.

Does anyone have an idea or suggestion, or should I go about it the long way?

James Davy · Apr 14, 2018

This code will allow you to set multiple mega forms using the same mega stone:

Code:

class PokeBattle_Pokemon
  def getMegaForm(itemonly=false)
    formdata = pbLoadFormsData
    [COLOR="Red"]multiformspec = [PBSpecies::NINETALES, PBSpecies::PIDGEOT][/COLOR] [COLOR="Green"]# add more species if necessary[/COLOR]
    return 0 if !formdata[@species] || formdata[@species].length==0
    ret = 0
    dexdata = pbOpenDexData
    for i in formdata[@species]
      next if !i || i<=0
      pbDexDataOffset(dexdata,i,29)
      megastone = dexdata.fgetw
      if megastone>0 && self.hasItem?(megastone)
        [COLOR="Red"]if multiformspec.include?(@species)
          ret = @form + 10; break
        else[/COLOR]
          ret = i; break
        [COLOR="red"]end[/COLOR]
      end
      if !itemonly
        pbDexDataOffset(dexdata,i,56)
        megamove = dexdata.fgetw
        if megamove>0 && self.hasMove?(megamove)
          ret = i; break
        end
      end
    end
    dexdata.close
    return ret  # fSpecies or 0
  end

This will ensure form 1 goes to form 11, form 2 goes to form 12, etc.

You could as well add a condition to the pbs file. Just like MegaMove, which enables Mega Evolution only when a certain move is known. You could call it like MegaForm or sth. But it requiressome scripting to make this possible. On the positive side though it makes it much easier to define those special forms for multiple Pokemon. I think it's a good option unless you only need to define 1-4 Mons.

That can be done as follows:

In Compiler, add the line in red under this line:

Code:

    "MegaMessage"      => [58,"u"]
    [COLOR="Red"]"MegaForm"         => [59,"u"][/COLOR]

In Pokemon_MegaEvolution, add the lines in red:

Code:

class PokeBattle_Pokemon
  def getMegaForm(itemonly=false)
    formdata = pbLoadFormsData
    return 0 if !formdata[@species] || formdata[@species].length==0
    ret = 0
    dexdata = pbOpenDexData
    for i in formdata[@species]
      next if !i || i<=0
      pbDexDataOffset(dexdata,i,29)
      megastone = dexdata.fgetw
      if megastone>0 && self.hasItem?(megastone)
        ret = i; break
      end
      if !itemonly
        pbDexDataOffset(dexdata,i,56)
        megamove = dexdata.fgetw
        if megamove>0 && self.hasMove?(megamove)
          ret = i; break
        end
      end
      [COLOR="Red"]pbDexDataOffset(dexdata,i,59)
      megaform = dexdata.fgetb
      if megaform>0 && self.hasItem?(megastone)
        ret = i; break
      end[/COLOR]
    end
    dexdata.close
    return ret  # fSpecies or 0
  end

Is it tested? Looks like exactlywhat I had in mind

James Davy · Apr 14, 2018

During testing, I realised an even easier method that doesn't involve adding new keys to pokemon.txt or pokemonforms.txt:

Code:

class PokeBattle_Pokemon
  def getMegaForm(itemonly=false)
    formdata = pbLoadFormsData
    return 0 if !formdata[@species] || formdata[@species].length==0
    ret = 0
    dexdata = pbOpenDexData
    for i in formdata[@species]
      next if !i || i<=0
      pbDexDataOffset(dexdata,i,29)
      megastone = dexdata.fgetw
      if megastone>0 && self.hasItem?(megastone)
        [COLOR="Red"]pbDexDataOffset(dexdata,i,37)
        unmegaform = dexdata.fgetb
        if @form == unmegaform
          [/COLOR]ret = i; break
        [COLOR="Red"]end[/COLOR]
      end
      if !itemonly
        pbDexDataOffset(dexdata,i,56)
        megamove = dexdata.fgetw
        if megamove>0 && self.hasMove?(megamove)
          ret = i; break
        end
      end
    end
    dexdata.close
    return ret  # fSpecies or 0
  end

Sorry for the delay. That?s exactly the script I was trying to make on my own. Was closer than I thought! But I don?t have a very deep understanding of how it works.

When I implement this last one you sent - and I triple checked to make sure it?s all in there properly - my Pok?mon goes to the correct Mega form, but skips the mega evo animation and doesn?t devolve at the end of the battle for some reason. I had this issue in some of my own attempts at well.

Think I forgot to mention that I?m using EBS. Would that make a difference here? Sorry; it didn?t even occur to me until now that it could potentially play a role in the issue.

James Davy · Apr 15, 2018

I don't really know if scripting on the EBS is any different compared to the original.

There might be an unmega script in the ebs that you need to modify

AaronPendragon · Apr 16, 2018

In any case, thank you so much for the script and the help. And I?ll be searching the EBS section for everything related to mega evolution to check for hints. The word ?unmega? isn?t in that area at all, but the issue has to be in here or an area referenced by it, I suppose.

I recommend using the general search to find all instances of the word unmega

AaronPendragon · Apr 17, 2018

That was my initial thought, but it turned out that the term isn?t used a single time in all of the EBS scripts. I spent most of yesterday and all of this morning trying to get the issue ironed out, and just now got it to manage the forms properly by making a few changes to the original MegaEvolution script. Now, I believe all that?s amiss is the animation for the mega evolving process, which isn?t playing at all. Hopefully that won?t take as long to figure out!

I think the animation is not even there in vanilla essentials. Then you'd need to add it

AaronPendragon · Apr 17, 2018

Okay, I thought that was the case. We initially planned not to use EBS, then changed our minds a couple of months ago, but we didn?t add any Megas until just a few weeks ago. The animation apparently came with EBS, because it worked until I brought in variants of Megas within the same species. Just had to adjust several things here and there, but I hope I don?t have to do it again. Forgot to make notes on a couple of the changes. :/
