In particular, it only activates after all hits in a multi-hit move are performed, and
it won't activate if the move is boosted by Sheer Force.
This commit also implements the interactions of Emergency Exit
with Eject Button and Red Card, and adds tests.
BattlePokemon#runImmunity is now two functions, runImmunity and
runStatusImmunity.
The split is helpful because: 1. NegateImmunity only applies to type
immunities, and 2. Immunity only applies to status immunities and
Ground immunities.
Ground immunities are now entirely handled hardcoded in isGrounded.
This overall doesn't have a noticeable impact on performance, but
it makes certain things behave more predictably, and correctly
shows the ability activation for Levitate, so I assume that means it's
a net positive. I hope I at least improved readability...
PS has a tradition of supporting future-gen items/moves/etc in past gens,
so why not the other way around? Obviously, these items are banned
outside of Custom Game.
This mainly helps make the teambuilder less confusing to gen 2 players.
- Introduces `battleOnly` to Pokémon formats-data to flag which formes are forbidden on battle start.
- Adds back Secret Sword as Keldeo-Resolute's required move.
- Introduces `requiredAbility` to handle Darmanitan-Zen.
- Introduces `forcedForme` to items' data to flag the formes that some items enforce.
The current implementation of ModifyAtk, ModifyDef, etc. is to pass the
actual stat into the event, have event handlers run battle.chainModify(),
ModifySpe passes in a modifier variable, calls battle.chain(), and then
ends with battle.modify() using the modifier variable. The way chainModify
is implemented within the event system also means that it chains together
modifiers in the same manner and finishes with battle.modify(), meaning
that there is no need for ModifySpe to use battle.chain() and
battle.modify() manually.
This also fixes the effect of BattlePokemon#getStat on stats other than
speed.
