[Eventing Question] Changing Event Graphic based on Party Pokemon

[monkeyboy6]

In a game I'm working on, there are various events that allow your Pokemon to interact with the environment, kind of like HMs, except instead of checking for a certain move, the event checks that you have a certain type of Pokemon.

The current event I'm working on allows the player to burn down vines if they have a fire Pokemon in their party. After creating the event, I decided it would be cool if the player could actually send out their Pokemon to burn down the vines, like so:

Spoiler:

However, in this instance, I have just made the event use Houndour, because I knew that's what I had in my party. I was wondering if there was a way that my event can check for the first Fire Pokemon in the player's party and use the graphic for that Pokemon for the event?

returns pokemon object that has type

def pbCheckType(type)
  if type.is_a?(String) || type.is_a?(Symbol)
    type = getID(PBTypes,type)
  end
  for i in $Trainer.party
    next if i.egg?
    return i if i.hasType?(type)
  end
  return nil
end

Code that loads pokemon overworld file (my file structure is put all the overworlds in characters/pkmn)

def pbPokemonOverworldFile(params)
  species = params[0]
  back    = params[1]
  factors = []
  factors.push([5,params[5],false]) if params[5] && params[5]!=false     # shadow
  factors.push([2,params[2],false]) if params[2] && params[2]!=false     # gender
  factors.push([3,params[3],false]) if params[3] && params[3]!=false     # shiny
  factors.push([4,params[4].to_s,""]) if params[4] && params[4].to_s!="" &&
                                                      params[4].to_s!="0" # form
  tshadow = false
  tgender = false
  tshiny  = false
  tform   = ""
  for i in 0...2**factors.length
    for j in 0...factors.length
      case factors[j][0]
      when 2   # gender
        tgender = ((i/(2**j))%2==0) ? factors[j][1] : factors[j][2]
      when 3   # shiny
        tshiny = ((i/(2**j))%2==0) ? factors[j][1] : factors[j][2]
      when 4   # form
        tform = ((i/(2**j))%2==0) ? factors[j][1] : factors[j][2]
      when 5   # shadow
        tshadow = ((i/(2**j))%2==0) ? factors[j][1] : factors[j][2]
      end
    end
    bitmapFileName = sprintf("pkmn/%s%s%s%s%s%s",
       getConstantName(PBSpecies,species),
       (tgender) ? "f" : "",
       (tshiny) ? "s" : "",
       (back) ? "b" : "",
       (tform!="") ? "_"+tform : "",
       (tshadow) ? "_shadow" : "") rescue nil
    ret = pbResolveBitmap("Graphics/Characters/"+bitmapFileName)
    return bitmapFileName if ret
    bitmapFileName = sprintf("pkmn/%03d%s%s%s%s%s",
       species,
       (tgender) ? "f" : "",
       (tshiny) ? "s" : "",
       (back) ? "b" : "",
       (tform!="") ? "_"+tform : "",
       (tshadow) ? "_shadow" : "")
    ret = pbResolveBitmap("Graphics/Characters/"+bitmapFileName)
    return bitmapFileName if ret
  end
  return ""
end

Calling the above code (returns the file name that you set the event graphic to.)

event.character_name=pbPokemonOverworldFile([pkmn.species,false,(pkmn.isFemale?),
       pkmn.isShiny?,(pkmn.form rescue 0),(pkmn.isShadow? rescue false)])

Set the event variable by grabbing it directly, so event X is pulled with $game_map.events[X]. Alternatively, stuff the graphic setting code in a helper method, and pass get_character(X) as well as the pokemon object.

This is kind of scattered, I know, kind of ripping out bits and pieces of code from my other projects. The bitmap and graphic code is tested and works, but I can't guarantee the same for the type check. It's a modification of the move check though, so probably works.

I appreciate the response Vendily! I'm not that savvy with scripts and whatnot,but I'd love to learn some things here, so I'd appreciate if you helped me out a bit more. I'm not really understanding where I should be putting the bits of code you wrote. And then how to go about calling everything in my event... ?

 

[Vendily]

Sorry, yeah, guess more explanation is in order, huh?
Well those first two methods, they are top level, so you can just make a new script section and plop them in, easy peasy.

The helper method, we need two things for that, the pokemon object, and the event that we want to apply the graphic to.

def pbSetPokemonEventGraphic(pkmn,event)
  event.character_name=pbPokemonOverworldFile([pkmn.species,false,(pkmn.isFemale?),
       pkmn.isShiny?,(pkmn.form rescue 0),(pkmn.isShadow? rescue false)])
end

now that we have a helper method all set up, we can get to the event stuff.
first we need to get the pokemon object, which you said is the first fire type.

pkmn=pbCheckType(:FIRE)

This method can return nil though so in the event, you should put a conditional branch with the script condition pbHasType?(:FIRE) if you haven't already and stick the checktype in there.
Now we need to set the graphic, so it's helper method time.
To set the graphic of the event with id X, we need to pass get_character(X) to it. NO PADDED ZEROS! It's event id 4, not 004! Else ruby thinks it's an octal and your 010 becomes 8.

pbSetPokemonEventGraphic(pkmn,get_character(X))

If the event that transforms into a pokemon is the event you activate, you can also make it get_character(0). (While not necessary for this tutorial, the player is get_character(-1))
rest of the event is basically the same as what you have, pokemon moves, flame, you put it away, no variables for that.

Never been much of a tester, so while it should work, let me know if something funky happens.

 

[monkeyboy6]

Awesome! Got it working! Thanks so much for your help!

Know this is a bit old, but managed to mostly get this working in v19.1, though have an extremely odd issue where it's throwing up an error only when checking certain types, not all types. Any help would be appreciated
