[Scripting Question] Help me with Pokemon Evolution!

[KokoNekoGirl]

So I'm new to scripting (I only rlly have experience with bits of java with my computer programing class) so i tried to find tutorials to help me. I want to add two evolution ways: one by levelling up a pokemon during a sandstorm (Named Dusteon), and one by having a pokemon level up while holding a specific held item (many more eeveelutions). I followed one tutorial, and I went over to the Pokemon_Evolution scripting and changed custom 1 and custom 2 to:
LevelSandstorm = 31
HoldItem = 32

I then scrolled down and changed values, this is what it looked like:

1,2,1,1,1 # LevelSandstorm, HoldItem, Custom 2-5

I scrolled further down and wrote this code (where it told me to put it):

when PBEvolution::LevelSandstorm
if pokemon.level>=level
if $game_screen && (PBFieldWeather==PBFieldWeather::Sandstorm || PBWeather==PBWeather::SANDSTORM);


when PBEvolution::HoldItem
if ((pokemon.item==level) &&((isConst?(pokemon.species,PBSpecies,:IGNEON)) || (isConst?(pokemon.species,PBSpecies,:AIREON))|| (isConst?(pokemon.species,PBSpecies,:CORRUPTEON))|| (isConst?(pokemon.species,PBSpecies,:MARBELLEON)) || (isConst?(pokemon.species,PBSpecies,:BERYLLEON)));

I even added this part a bit lower just to be sure:

when PBEvolution::HoldItem
return poke if level==item && ((isConst?(pokemon.species,PBSpecies,:IGNEON) || (isConst?(pokemon.species,PBSpecies,:AIREON)|| (isConst?(pokemon.species,PBSpecies,:CORRUPTEON)|| (isConst?(pokemon.species,PBSpecies,:MARBELLEON) || (isConst?(pokemon.species,PBSpecies,:BERYLLEON)));

However, I keep getting script errors. The program we use in class specifies what is wrong with the code (ie: Unknown variables, incorrect use of data types, etc), however idk exactly what script errors mean? I don't even know what these variables or commands mean ;w; Can somemone help me through this?

It might help people answer if you use code tags to preserve the indentation of your code when you post, and put the error messages here too (and point out which line numbers they correspond to in your code, if they do).

I also forgot:

line 40

line 41

"TradeItem","Item","AttackGreater","AtkDefEqual","DefenseGreater",

line 42

"Silcoon","Cascoon","Ninjask","Shedinja","Beauty",

line 43

"ItemMale","ItemFemale","DayHoldItem","NightHoldItem","HasMove",

line 44

line 45

"LevelDay","LevelNight","LevelDarkInParty","LevelRain","HappinessMoveType",

line 46

"LevelSandstorm","HoldItem","Custom3","Custom4","Custom5"

The error was happening at 922. it also still happened without the ; at the end. Does that help?

Hi,

Essentials/RMXP by itself is telling you exactly what line causes the error in it's error message and what kind of error it is. If you could show us this message it would make it easier for us to help you

ok i updated the original post. I got the item one to work, just the sandstorm giving me problems

The sandstorm evo method is very similar to the already implemented rain evo, so that would be a great place to start.

when PBEvolution::LevelRain
    if pokemon.level>=level
      if $game_screen && ($game_screen.weather==PBFieldWeather::Rain ||
                          $game_screen.weather==PBFieldWeather::HeavyRain ||
                          $game_screen.weather==PBFieldWeather::Storm)
        return poke
      end
    end

Now we don't need to worry about PBWeather, because that's for in battle weather, and pokemon can't evolve in battle.

when PBEvolution::LevelSandstorm
    if pokemon.level>=level
      if $game_screen && ($game_screen.weather==PBFieldWeather::Sandstorm)
        return poke
      end
    end

That'll do the trick. There's a lot to learn from the default scripts, so it's a good idea to always give a quick look at stuff that's similar to what you want.
CTRL + SHIFT + F lets you search all script sections at once, making tracking down what you are looking for way easier!

Ah! Thanks for the tip! I was trying to base the level sandstorm off the level rain, however i'm still getting the same error as before :'3 Idk why my post reverted to the original, i thought i edited it. anyways, https: //imgur. com/a/3Jj3MGD these are the errors

 

[Vendily]

Oh no, I am so sorry, looks like the LevelRain evo method is also wrong. $game_screen.weather is what we call to switch the weather. We want $game_screen.weather_type

So sorry.

Oh it's fine!! IT WORKED HORRAYYY :'33 now to just add all the pokemon now! tysm!
