[Eventing Question] How to make a NPC to set Pokemon Levels

[burningplain]

Does anyone have an idea of how to create an npc to set a pokemon to a specific level? This would be a prexisting Pokemon, and it would not necessarily need to learn the moves it would gain by level up for the levels it is skipping.
Basically I want an npc to insta-level Pokemon to a Gym's Level Cap once that get to the Gym Leader, and then to the previous level cap while they work there way to the next Gym, but I can't figure out how to make a npc just a give a Pokemon levels.

I have figured it out. There is already a script called pbChangeLevel (used by Rare Candies) that can be used to increase the level of your Pokemon. It uses 4 variables, pkmn,newlevel,scene,checkmoves=true/false. However, I couldn't figure out how to properly define the scene variable for an overworld map, so I created a new script based off this instead. It removes all mention of scene for the script, and only has two variables, pkmn and new level.

Spoiler:

def pbFastLevel(pkmn,newlevel)
oldlevel = pkmn.level
newlevel = newlevel.clamp(1, GameData::GrowthRate.max_level)
if pkmn.level==newlevel
pbMessage(_INTL("{1}'s level remained unchanged.",pkmn.name))
newspecies = pkmn.check_evolution_on_level_up
if newspecies
pbFadeOutInWithMusic {
evo = PokemonEvolutionScene.new
evo.pbStartScreen(pkmn,newspecies)
evo.pbEvolution
evo.pbEndScreen
}
end
elsif pkmn.level>newlevel
attackdiff = pkmn.attack
defensediff = pkmn.defense
speeddiff = pkmn.speed
spatkdiff = pkmn.spatk
spdefdiff = pkmn.spdef
totalhpdiff = pkmn.totalhp
pkmn.level = newlevel
pkmn.calc_stats
pbMessage(_INTL("{1} dropped to Lv. {2}!",pkmn.name,pkmn.level))
attackdiff = pkmn.attack-attackdiff
defensediff = pkmn.defense-defensediff
speeddiff = pkmn.speed-speeddiff
spatkdiff = pkmn.spatk-spatkdiff
spdefdiff = pkmn.spdef-spdefdiff
totalhpdiff = pkmn.totalhp-totalhpdiff
pbTopRightWindow(_INTL("Max. HP<r>{1}\r\nAttack<r>{2}\r\nDefense<r>{3}\r\nSp. Atk<r>{4}\r\nSp. Def<r>{5}\r\nSpeed<r>{6}",
totalhpdiff,attackdiff,defensediff,spatkdiff,spdefdiff,speeddiff))
pbTopRightWindow(_INTL("Max. HP<r>{1}\r\nAttack<r>{2}\r\nDefense<r>{3}\r\nSp. Atk<r>{4}\r\nSp. Def<r>{5}\r\nSpeed<r>{6}",
pkmn.totalhp,pkmn.attack,pkmn.defense,pkmn.spatk,pkmn.spdef,pkmn.speed))
else
attackdiff = pkmn.attack
defensediff = pkmn.defense
speeddiff = pkmn.speed
spatkdiff = pkmn.spatk
spdefdiff = pkmn.spdef
totalhpdiff = pkmn.totalhp
pkmn.level = newlevel
pkmn.calc_stats
pbMessage(_INTL("{1} grew to Lv. {2}!",pkmn.name,pkmn.level))
attackdiff = pkmn.attack-attackdiff
defensediff = pkmn.defense-defensediff
speeddiff = pkmn.speed-speeddiff
spatkdiff = pkmn.spatk-spatkdiff
spdefdiff = pkmn.spdef-spdefdiff
totalhpdiff = pkmn.totalhp-totalhpdiff
pbTopRightWindow(_INTL("Max. HP<r>+{1}\r\nAttack<r>+{2}\r\nDefense<r>+{3}\r\nSp. Atk<r>+{4}\r\nSp. Def<r>+{5}\r\nSpeed<r>+{6}",
totalhpdiff,attackdiff,defensediff,spatkdiff,spdefdiff,speeddiff))
pbTopRightWindow(_INTL("Max. HP<r>{1}\r\nAttack<r>{2}\r\nDefense<r>{3}\r\nSp. Atk<r>{4}\r\nSp. Def<r>{5}\r\nSpeed<r>{6}",
pkmn.totalhp,pkmn.attack,pkmn.defense,pkmn.spatk,pkmn.spdef,pkmn.speed))
# Check for evolution
newspecies = pkmn.check_evolution_on_level_up
if newspecies
pbFadeOutInWithMusic {
evo = PokemonEvolutionScene.new
evo.pbStartScreen(pkmn,newspecies)
evo.pbEvolution
evo.pbEndScreen
}
end
end
end

There are 3 major changes to this script from the normal pbLevelUp. One, it doesn't update the scene at all, which means it should not be used in the Pokemon Party Screen, as it won't accurately show your Pokemon leveling up.
Two, your Pokemon will not learn moves via level up, unless it evolves and the new Pokemon learns a move at that level. I'd recommend pairing it with a Move Relearner.
Finally, I added the evolution check to proc even if it does not increase in level. This way, even if you are already at the level cap, you can evolve Pokemon who you've either delayed evolution on or have multiple stages.

This may have been a redundant command, but it works.
