[Scripting Question] Adding a flag or switch to make any Mon not in the Dex evolve

[theRiolvile]

Yes you read it right I'm been dreading to make a switch or own plugin to prevent evolving a mon so I know it's gonna sound strange but why not have a Golbat, Chansey or any mon not in the Pokedex. but no way I could write it as I took lot of my time looking and searching for has_nationaldex.

I could add :

[GOLBAT]
Name = Golbat
Types = POISON,FLYING
BaseStats = 75,80,70,90,65,75
GenderRatio = Female50Percent
GrowthRate = Medium
BaseExp = 159
EVs = SPEED,2
CatchRate = 90
Happiness = 50
Abilities = INNERFOCUS
HiddenAbilities = INFILTRATOR
Moves = 1,SCREECH,1,ABSORB,1,SUPERSONIC,1,ASTONISH,1,MEANLOOK,15,POISONFANG,20,QUICKGUARD,27,AIRCUTTER,34,BITE,41,HAZE,48,VENOSHOCK,55,CONFUSERAY,62,AIRSLASH,69,LEECHLIFE
TutorMoves = ACROBATICS,AERIALACE,AGILITY,AIRSLASH,ASSURANCE,ATTRACT,BRAVEBIRD,CRUNCH,DEFOG,DOUBLETEAM,DUALWINGBEAT,ENDURE,FACADE,FLY,GIGADRAIN,GIGAIMPACT,HEATWAVE,HIDDENPOWER,HYPERBEAM,LEECHLIFE,NASTYPLOT,PAYBACK,PLUCK,PROTECT,RAINDANCE,REST,ROOST,ROUND,SCREECH,SHADOWBALL,SLEEPTALK,SLUDGEBOMB,SNORE,STEELWING,SUBSTITUTE,SUNNYDAY,SWAGGER,SWIFT,TAUNT,THIEF,TORMENT,UPROAR,UTURN,VENOMDRENCH,VENOSHOCK,ZENHEADBUTT
EggGroups = Flying
HatchSteps = 3840
Height = 1.6
Weight = 55.0
Color = Purple
Shape = Winged
Habitat = Cave
Category = Bat
Pokedex = Its fangs easily puncture even thick animal hide. It loves to feast on the blood of people and Pokémon. It flits about in darkness and strikes from behind.
Generation = 1
Evolutions = CROBAT,Happiness, "Nationdex Restricted"

There's no way to make a switch making a specie evolve without a certain switch unless.. I need to create a Nationdex item lol

You'd just need to include a check for

$game_switches[29]

being on in a separate evolution method; In v19 and v20 this switch is the National Dex switch. Make sure to have it registered separately from the original

Could you show me an example or does it need to link with the flag or something?

 

[Vendily]

Huh, talk about déjà vu.
I typed up the code for this in v20 for a different user just yesterday.
(broken link removed)

 

[theRiolvile]

That was me but thanks I may get more better at the coding as I do enjoy it!
I tested it and it worked well it did the function it did but there's no way of showing the evo screen and showing that ??? for a tease like frlg.
