v20.1 - Substitube's Poké Balls

Pokémon Essentials Version: v20.1 ➖

There's a whopping 58 designs in this video! Some of that is the same concept multiplied out (balls for Egg Groups, balls for types, etc.), but a lot of them are totally unique effects! I've adapted most of these for Essentials v20 and have the Poké Ball handlers and PBS entries here!

A few notes:

The following Poké Balls were skipped, but may be added in the future:
- Nuzlocke Ball
- Plus Ball
- Multi Ball
- Blast Ball
There are no graphics, just code.
No exact numbers were given for the catch rate boost, so everything was set to a 3x multiplier. (Except for balls with clear counterparts, like the Dawn Ball/Shrink Ball)
Similarly, no buy/sell price was given, so all balls are set to $1000
Following Net Ball's example, any ball with multiple conditions does not stack. (For example, even though a Surskit is Bug/Water, a Net Ball is just as effective on it as it would be on a Pokémon that's just Water-type)

You are, of course, welcome to tweak these however you see fit.

I have two ways to add these - a bulk installation where you just add them all in at once, and an individual listing section where the handler (and/or relevant code) and PBS entry is listed for each specific Poké Ball. (This is also where I clarify more on the exact mechanics.)

Paste this in a script section above Main, and add this to items.txt.

For the Dawn Ball -
To implement the inside-buildings feature, you'll have to do a little bit of extra work.

In Overworld_BattleStarting, find these lines:

Ruby:

    if $game_map.metadata&.battle_environment == :Cave
      battle.time = 2   # This makes Dusk Balls work properly in caves

Below them, add these:

Ruby:

    elsif $game_map.metadata&.battle_environment == :None
      battle.time = 0   # This makes Dawn Balls work properly indoors

Every map with the battle environment set to None in its map metadata will have a boost to Dawn Balls. To my knowledge, this should not affect anything else in-battle, as time-dependent mechanics aren't used in battle anymore to account for multiplayer functions across time zones. But if you've introduced mechanics that you think wouldn't pair well with this, or you've got an indoor location where it wouldn't make sense (like the Underground Path in Kanto), you may want to consider making another battle environment for Dawn Ball's effect.

For the Seeker Ball -
In the script section Item_BattleEffects, find this line:

Ruby:

    if battler.semiInvulnerable?

And change it to:

Ruby:

    if battler.semiInvulnerable? && !(item == :SEEKERBALL)

Add the following flags to any relevant species in pokemon.txt:

inorganic for any Pokémon made of artificial materials. (Voltorb, Trubbish, etc.) This is specifically to allow the Junk Ball to work on object-based Pokémon that aren't Steel-type, so you wouldn't need to add it to a species like Magnemite for it to work. But I would still recommend adding it anyways just in case you have any other mechanics that work on object-based Pokémon)
Mythic for any Mythical Pokémon, and Legendary for any Legendary.

Dex Ball - Registers the Pokémon in the dex as caught, even if it fails to catch.

Ruby:

Battle::PokeBallEffects::OnFailCatch.add(:DEXBALL, proc { |ball, battle, battler|

    battle.pbPlayer.pokedex.set_owned(battler.species)
    if $player.has_pokedex
      battle.pbDisplayPaused(_INTL("{1}'s data was added to the Pokédex.", battler.pokemon.speciesName))

Ruby:

Battle::PokeBallEffects::ModifyCatchRate.add(:DAWNBALL, proc { |ball, catchRate, battle, battler|

Price = 1000
BattleUse = OnFoe
Flags = PokeBall

Taunt Ball - Applies Taunt if it fails to catch the Pokémon. (Can't stack Taunt Ball and Taunt. Can use a Taunt Ball on a taunted Pokémon, but it'll just work like a regular Poké Ball. Will trigger a held Mental Herb.)

Ruby:

Battle::PokeBallEffects::OnFailCatch.add(:TAUNTBALL, proc { |ball, battle, battler|
    unless battler.effects[PBEffects::Taunt] > 0
      battler.effects[PBEffects::Taunt] = 4

Description = A tactical Poké Ball that enrages any Pokémon it fails to catch, preventing them from using status moves.

Penalty Ball - Applies the effect of Disable if it fails to catch the Pokémon. (No effect if used first turn in a battle, can't disable multiple moves, have to wait for the effects of Disable/Penalty Ball to wear off before disabling another move. Can still throw another Penalty Ball, will just work like a regular Poké Ball. Will trigger a held Mental Herb.)

Ruby:

Flags = PokeBall
Description = A tactical Poké Ball. If it fails to catch a Pokémon, it will disable their last-used move.

Concuss Ball - Causes the Pokémon to flinch if it fails to catch it. (This does interact with abilities - Steadfast will be triggered, and Inner Focus will prevent the flinching, though it currently doesn't display any message.)

Description = An all-natural Poké Ball that heals any Pokémon it fails to catch.

Lock Ball - Prevents the Pokémon from fleeing if it fails to catch it, using the same mechanic as Mean Look. Substitube's description said it would only prevent it for one turn, but it was simpler to make it permanent. Does not affect a Pokémon if another Pokémon on the field has already trapped them, if they're a Ghost-type and you've set MORE_TYPE_EFFECTS in Settings to true, or if the target is behind a Substitute.

Ruby:

Battle::PokeBallEffects::OnFailCatch.add(:LOCKBALL, proc { |ball, battle, battler|

Rus Ball - The exact mechanics here were not especially clear - Substitube only said this would have "an increased chance of inflicting PokéRus". They put this in the section for balls with effects that trigger on failing to catch, but I don't see why this wouldn't apply as well if you caught it? And of course the specific odds weren't given. So what I've done is make it where on failing or succeeding to catch the Pokémon, there's another chance of the Pokémon catching PokéRus, this time with 2x the odds. (I was considering doing a Luxury Ball thing where Pokémon would be more susceptible to PokéRus if they were inside a Rus Ball, but apparently that's not how PokéRus works!)

Clear Ball - Increased rate on Normal-types and Pokémon with type-changing abilities. (Color Change, Multitype, RKS System, Protean, Libero, or Mimicry) Note that it doesn't account for any in-battle changes in ability - if you used Skill Swap to pass one of these abilities over, it wouldn't affect the catch rate.

Substitube gave quick ideas for balls that depended on the dex color or body shape, but didn't give any names or designs, so I'm going to give examples of how these handlers would work, but not make a full set.

Here's an example of a handler that checks the dex color of a Pokémon:

Ruby:

Battle::PokeBallEffects::ModifyCatchRate.add(:BLUEBALL, proc { |ball, catchRate, battle, battler|
  catchRate *= 3 if battler.pokemon.species_data.color == :Blue
  next catchRate
})

Here's an example of a handler that checks the body shape of a Pokémon:

Ruby:

Battle::PokeBallEffects::ModifyCatchRate.add(:SNAKEBALL, proc { |ball, catchRate, battle, battler|
  catchRate *= 3 if battler.pokemon.species_data.shape == :Serpentine
  next catchRate
})

No graphics for most of these yet, but A.I.R made a bag sprite for the Elder Ball, Yule Ball, and Dawn Ball!
