Rewrites a good amount of legality APIs pertaining to:
* Legal moves that can be learned
* Evolution chains & cross-generation paths
* Memory validation with forgotten moves
In generation 8, there are 3 separate contexts an entity can exist in: SW/SH, BD/SP, and LA. Not every entity can cross between them, and not every entity from generation 7 can exist in generation 8 (Gogoat, etc). By creating class models representing the restrictions to cross each boundary, we are able to better track and validate data.
The old implementation of validating moves was greedy: it would iterate for all generations and evolutions, and build a full list of every move that can be learned, storing it on the heap. Now, we check one game group at a time to see if the entity can learn a move that hasn't yet been validated. End result is an algorithm that requires 0 allocation, and a smaller/quicker search space.
The old implementation of storing move parses was inefficient; for each move that was parsed, a new object is created and adjusted depending on the parse. Now, move parse results are `struct` and store the move parse contiguously in memory. End result is faster parsing and 0 memory allocation.
* `PersonalTable` objects have been improved with new API methods to check if a species+form can exist in the game.
* `IEncounterTemplate` objects have been improved to indicate the `EntityContext` they originate in (similar to `Generation`).
* Some APIs have been extended to accept `Span<T>` instead of Array/IEnumerable
* Revises legality checks to account for traveling between the three game islands (PLA/BDSP/SWSH)
* Adds conversion mechanisms between the three formats, as well as flexible conversion options to backfill missing data (thanks GameFreak/ILCA for opting for lossy conversion instead of updating the games).
* Adds API abstractions for HOME data storage format (EKH/PKH format 1, aka EH1/PH1).
* Revises some APIs for better usage:
- `PKM` now exposes a `Context` to indicate the isolation context for legality purposes.
- Some method signatures have changed to accept `Context` or `GameVersion` instead of a vague `int` for Generation.
- Evolution History is now tracked in the Legality parse for specific contexts, rather than only per generation.
struct implementing interface is boxed when passed to method that accepts interface (not generic method).
Removes IDexLevel (no other inheritors but EvoCriteria) and uses the primitive the data is stored (array, not IReadOnlyList) for slightly better perf.
* Make EvolutionCriteria struct
8 bytes per object instead of 26
Unify LevelMin/LevelMax to match EncounterTemplate
bubble up precise array type for better iteration
* Inline queue operations, less allocation
* Inline some logic
* Update EvolutionChain.cs
* Improve clarity on duplicate move check
* Search reverse
For a dual stage chain, finds it first iteration rather than second.
Big thanks to @SciresM @sora10pls @Lusamine @architdate @ReignOfComputer for testing and contributing code / test cases. Can't add co-authors from the PR menu :(
Builds will fail because azure pipelines not yet updated with net6.
Check per-evolution min level rather than basing it on the original encounter data.
Correctly parses stuff like a captured level 23 Nidorina that immediately evolves into Nidoqueen, then learns Body Slam.
Passing zero is better than passing 1, as 0 requires no value pushing.
tidy up method signatures in MoveLevelUp so that species is followed by form, and the lookups are textually aligned. Clarify "maxLevel" instead of max/lvl, same as min.
EncounterArea now stores a more specific type'd array for encounter slots. Better iteration and less casting, as the nonspecific `Slots` fetch is rarely referenced.
EncounterType renamed to GroundTile to reflect how it actually works in Gen4. Was previously an ambiguous field that was clarified a little; we can describe it a little better now. Keep the GUI the same to not scare the end users.
Change Trash Byte properties to get/set a Span. Trash Byte legality checking easier on the garbage collector?
Simplify some method signatures, reduce checks for MoveEgg.GetEggMoves
ran legality checks for 100,000 pkm, no more exceptions (Internal Error) -- added a "CanGameGenerateEggs" which filters out unused gameIDs
AltForm & Form & Forme => Form
GenNumber & Generation => Generation
Extract out SpeciesForm interface, and re-add IGeneration
For those using PKHeX as a dependency, this should be a pretty straightforward manual replacement... GenNumber and AltForm should be quick find-replace`s.
took me less than an hour to do these changes, and i can flag bad form movesets no problemo
Expect tightening of restrictions (ball, level, shininess) later
if someone wants to curate met date restrictions, go ahead!
EncounterTrade: don't init Location to -1; keep as default 0 and use that as the pivot for default met location. Move Fateful property to the sub-type that uses it (EncounterTrade4, for Ranch).
Move some EncounterStatic->PKM logic that is per-type to the associated type overloaded methods. Rearrange order of properties to be more consistent with interfaces
Gen3: Initialize some classes without using post-constructor setters. The `init` setter functionality coming in c#9 won't be usable as the net46 runtime/netstandard2 doesn't support it on current previews. Do it this way so we can explicity initialize some required properties rather than apply version on a second iteration.
Move logic closer to where it is used rather than in larger static classes
EncounterStatic(7): move VC transfer template creation to class, simplify some sanity checks
EvoChain: g==2 case is never hit as the generation check at the top of the loop already skips
* Rework gen1 slot loading
Slot templates are precomputed from ROM data and just loaded straight in, with tight coupling to the encounter area (grouped by slot types).
* Revise fuzzy met check for underleveled wild evos
Example: Level 23 poliwhirl in RBY as a level 50 poliwhirl, will assume the chain is 25-50 for poliwhirl (as poliwag evolves at 25). Instead of revising the origin chain, just ignore the evo min level in the comparison.
Previous commit fixed it for gen1.
* Rework gen2-4 slot loading
Gen4 not finished, Type Encounter data and some edge encounters not recognizing yet...
* Add feebas slots for old/good encounters
* Begin moving properties
Great news! Gen5-7 need to be de-dumbed like Gen1-4.
Then I can remove the bang (!) on the Area accessor and ensure that it's never null!
* Split off XD pokespot slot encounter table type
* Set area in constructor
* Deduplicate g3 roaming encounters
* Deduplicate xd encounter locations (rebattle)
Only difference is met location; no need to create 500 extra encounter objects. A simple contains check is ok (rarely in gen3 format).
* Make all slots have a readonly reference to their parent area
* Minor clean
* Remove "Safari" slot type flag
Can be determined via other means (generation-location), allows us to reduce the size of SlotType member to a byte
Output of slot binaries didn't preserve the Safari flag anyway.
* Update SlotType.cs
* Handle type encounters correctly
* Merge safari area into regular xy area
* Merge dexnav accessor logic
* fix some logic so that tests pass again
rearrange g5 dw init to be done outside of static constructor (initializer instead)
PIDGenerator: friend safari slots now generate with required flawless IV count
* Add cianwood tentacool gift encounter
* Remove unnecessary abstractions
Fake area just returned a slot; since Slots have a non-null reference to the area, we can just return the slot and use the API to grab a list of possible slots for the chain.
Increase restrictiveness of location/type get-set operations
* Minor tweaks, pass parameters
DexNav observed state isn't necessary to use, only need to see if it's possible to dexnav. Now that we have metadata for slots, we can.
* Remove unused legality tables
no change in species/form from the crownite ore one afaik; common for both games???
fix type of rigel encount so it shows up in block editor, with correct name (ty matt)
(for good? pls)

remove GetMinimalLevel override, as it's doing the same thing as LevelMin. When regenerating the pkm, we aren't doing anything downlevel related.
all but egg exposed it; now, just make egg expose it and remove the unnecessary interface
we still need to Set generation for non-eggs/mgift, so have a separate Settable interface for internal purposes.
