In most other similar systems, like TeamValidator, we use `thing.dex` instead of having it extend `ModdedDex`. Battle has always extended `ModdedDex`, though. This changes Battle to match the others.
This should fix an issue with `Battle.data` not being cached.
This also frees up Battle to extend ObjectReadWriteStream<string> in a future update.
* Refactor validator
This is a major refactor intended to make the default rules easier to
understand, and also easier for OMs to bypass.
Removed rules:
- `Pokemon`: This is now `-Nonexistent`. Its previous name was intended
to be interpreted as "simulate the Pokémon games exactly, and only
allow what they allow". The new name should make it clearer that it
mainly bans CAPs and other nonexistent Pokémon and functionality.
- `-Illegal`: This is now `Obtainable` (see below).
- `Allow CAP`: This is now `+CAP`. Instead of having a hardcoded rule,
OMs can now be manually whitelist any pokemon/item/etc or group of
them, overriding `-Nonexistent`.
- `Ignore Illegal Abilities`: This is now `!Obtainable Abilities` (see
below).
`Obtainable` was previously `-Illegal`, and does the same thing: Makes
sure you have a regular Pokémon game with only Pokémon that can be
obtained without hacking.
But instead of being a ban, it's now a rule that does nothing by
itself, except contain more rules:
- `Obtainable Moves`
- `Obtainable Abilities`
- `Obtainable Formes`
- `Obtainable Misc`
- `-Nonexistent`
- `-Unreleased`
This allows OMs to piecemeal repeal and unban any of these individual
rules, instead of the previous approach of unbanning them all and
manually reimplementing every single validation you wanted to keep.
* Refactor PokemonSources into a class
This mostly just makes a lot of the weirder checks in the validator
substantially more readable.
This also renames `lsetData` to `setSources`, which should also help
readability.
* Validate Bottle Cap HP types
Fixes an issue reported here:
https://github.com/Zarel/Pokemon-Showdown/issues/5742#issuecomment-533850288
* Fix several move validation issues
Fixes#5742
We have a new MoveSource type: R for Restricted. R moves work like
level-up/tutor/TM moves, except you're limited to one R move.
- Shedinja move stolen from Ninjask in Gen 3-4 are now R moves instead
of event moves. This allows them to coexist with Nincada egg moves.
- Necrozma-DW/DM now inherit moves/events from Necrozma (like Rotom,
but with event validation). This allows them to be shiny.
- Pokemon can now get egg moves from their own evolutions. This fixes
some Tyrogue, Charmander, and Treecko sets mentioned in #5742
- Some more C moves were added, fixing some Hitmontop and Chatot sets
mentioned in #5742
* Improve ability/move compatibility validator
They were previously some weird interface where their actual types
were properties. I guess whoever wrote this was unaware that TypeScript
namespaces were designed for this exact use-case.
This is actually three refactors:
- swap around thing:slot for slot:thing in MoveHitData
- add Pokemon#getSlot
- remove the ActiveMove class; it's back to being an interface
See #5415 for context - having these methods is unsafe and leads
to crashes because not all ActiveMoves are created through the
Data.ActiveMove constructor. Instead of Pokemon, these could
alternatively be static methods on ActiveMove (or the ActiveMove
class could be completely abolished and reverted back to an
interface), but #5415 will deal with ActiveMove long term, this just
fixes the crashes.
Also move mods/ to data/mods/
This makes PS more monorepo-like. The intent is to further separate
the sim and the server code, but without fully committing to splitting
the repository itself.
We now support `./pokemon-showdown start` in addition to
`./pokemon-showdown`. I'm not clear which I want to be the default
yet.
