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
Many years ago, PKX used to be a >4,000 line bloated file, which spun off multiple classes like CommonEdits and most of the early non-GUI PKM related logic. Now, it's just a stub to source the latest generation & personal table.
Separate files = more concise info, and more room to grow to do more advanced things.
Makes the IsPresent methods public (no longer internal).
Existing `get`/`set` logic is flawed in that it doesn't work on Big Endian operating systems, and it allocates heap objects when it doesn't need to.
`System.Buffers.Binary.BinaryPrimitives` in the `System.Memory` NuGet package provides both Little Endian and Big Endian methods to read and write data; all the `get`/`set` operations have been reworked to use this new API. This removes the need for PKHeX's manual `BigEndian` class, as all functions are already covered by the BinaryPrimitives API.
The `StringConverter` has now been rewritten to accept a Span to read from & write to, no longer requiring a temporary StringBuilder.
Other Fixes included:
- The Super Training UI for Gen6 has been reworked according to the latest block structure additions.
- Cloning a Stadium2 Save File now works correctly (opening from the Folder browser list).
- Checksum & Sanity properties removed from parent PKM class, and is now implemented via interface.
* Track a PKM's Box,Slot,StorageFlags,Identifier metadata separately
Don't store within the object, track the slot origin data separately.
Batch editing now pre-filters if using Box/Slot/Identifier logic; split up mods/filters as they're starting to get pretty hefty.
- Requesting a Box Data report now shows all slots in the save file (party, misc)
- Can now exclude backup saves from database search via toggle (separate from settings preventing load entirely)
- Replace some linq usages with direct code
* Remove WasLink virtual in PKM
Inline any logic, since we now have encounter objects to indicate matching, rather than the proto-legality logic checking properties of a PKM.
* Use Fateful to directly check gen5 mysterygift origins
No other encounter types in gen5 apply Fateful
* Simplify double ball comparison
Used to be separate for deferral cases, now no longer needed to be separate.
* Grab move/relearn reference and update locally
Fix relearn move identifier
* Inline defog HM transfer preference check
HasMove is faster than getting moves & checking contains. Skips allocation by setting values directly.
* Extract more met location metadata checks: WasBredEgg
* Replace Console.Write* with Debug.Write*
There's no console output UI, so don't include them in release builds.
* Inline WasGiftEgg, WasEvent, and WasEventEgg logic
Adios legality tags that aren't entirely correct for the specific format. Just put the computations in EncounterFinder.
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.
Gen5: set HA bit if hidden ability
Gen3: prevent setting AbilityBit if it doesn't have 2 distinct abilities
Failed test now passes; all tests are passing!
