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.
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.
Yay abstractions to hide away the quirks.
BDSP traded eggs set HT_Friendship and the CurrentHandler flag, but the HatchCounter is always the OT_Friendship value.
Trades always receive BaseFriendship, instead of a hardcoded 50. Necessary to not hardcode because it's immutable for eggs.
Clicking the hatch counter label now sets it to the legal minimum hatch counter (best), and control clicking sets it to the max (worst). Check the encounter template for the true maximum.
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.
Slap on interface for EntreeSlot
De-magic some 💯 numbers to indicate what they're doing
Improve perf of move-match-relearn check
Add an "else" as valid is never both values (history verifier)
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?
* 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.
Add xmldoc
Remove linq from memecrypto code (speed lmao)
Hide some methods that shouldn't be called directly
Name variables better for accessor const's
