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.
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.
- Settings now stored as json next to exe
- Settings now exposes all legality checking setttings that can be changed
- Slot hovering now can play cries in MGDB/PKMDB/etc, not just the main boxes.
- Enhanced hover text for mystery gifts and encounters that have movesets
- Show recently loaded save files in ctrl-f browser
- Toggle auto-load savefile setting to be none/detect-latest/last-loaded
- Custom extensions & extra backup paths can now be configured directly in the json settings
- Settings editor now uses propertygrid & tabs.
## Issue
We want to discard-but-remember any slots that aren't a perfect fit, on the off chance that a better one exists later in the search space. If there's no better match, then we gotta go with what we got.
## Example:
Wurmple exists in area `X`, and also has a more rare slot for Silcoon, with the same level for both slots.
* We have a Silcoon that we've leveled up a few times.
Was our Silcoon originally a Wurmple, or was it caught as a Silcoon?
* To be sure, we have to check the EC/PID if the Wurmple wouldn't evolve into Cascoon instead.
* We don't want to wholly reject that Wurmple slot, as maybe the Met Level isn't within Silcoon's slot range.
---
Existing implementation would store "deferred" matches in a list; we only need to keep 1 of these matches around (less allocation!). We also want to differentiate between a "good" deferral and a "bad" deferral; I don't think this is necessary but it's currently used by Mystery Gift matching (implemented for the Eeveelution mystery gifts which matter for evolution moves).
The existing logic didn't use inheritance, and instead had static methods being reused across generations. Quite kludgy. Also, the existing logic was a pain to modify the master encounter yield methods, as one generation's quirks had to not impact all other generations that used the method.
---
The new implementation splits out the encounter yielding methods to be separate for each generation / subset. Now, things don't have to check `WasLink` for Gen7 origin, because Pokémon Link wasn't a thing in Gen7.
---
## Future
Maybe refactoring yielders into "GameCores" that expose yielding behaviors / properties, rather than the static logic. As more generations and side-gamegroups get added (thanks LGPE/GO/GameCube), all this switch stuff gets annoying to maintain instead of just overriding/inheritance.
## Conclusion
This shouldn't impact any legality results negatively; if you notice any regressions, report them! This should reduce false flags where we didn't defer-discard an encounter when we should have (wild area mons being confused with raids).
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.
Handle all warnings
obviously the usage of null! could potentially be avoided if the object init wasn't such garbage, but here we are with years of old junk and lack of abstraction in the GUI project
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.
* Handle some nullable cases
Refactor MysteryGift into a second abstract class (backed by a byte array, or fake data)
Make some classes have explicit constructors instead of { } initialization
* Handle bits more obviously without null
* Make SaveFile.BAK explicitly readonly again
* merge constructor methods to have readonly fields
* Inline some properties
* More nullable handling
* Rearrange box actions
define straightforward classes to not have any null properties
* Make extrabyte reference array immutable
* Move tooltip creation to designer
* Rearrange some logic to reduce nesting
* Cache generated fonts
* Split mystery gift album purpose
* Handle more tooltips
* Disallow null setters
* Don't capture RNG object, only type enum
* Unify learnset objects
Now have readonly properties which are never null
don't new() empty learnsets (>800 Learnset objects no longer created,
total of 2400 objects since we also new() a move & level array)
optimize g1/2 reader for early abort case
* Access rewrite
Initialize blocks in a separate object, and get via that object
removes a couple hundred "might be null" warnings since blocks are now readonly getters
some block references have been relocated, but interfaces should expose all that's needed
put HoF6 controls in a groupbox, and disable
* Readonly personal data
* IVs non nullable for mystery gift
* Explicitly initialize forced encounter moves
* Make shadow objects readonly & non-null
Put murkrow fix in binary data resource, instead of on startup
* Assign dex form fetch on constructor
Fixes legality parsing edge cases
also handle cxd parse for valid; exit before exception is thrown in FrameGenerator
* Remove unnecessary null checks
* Keep empty value until init
SetPouch sets the value to an actual one during load, but whatever
* Readonly team lock data
* Readonly locks
Put locked encounters at bottom (favor unlocked)
* Mail readonly data / offset
Rearrange some call flow and pass defaults
Add fake classes for SaveDataEditor mocking
Always party size, no need to check twice in stat editor
use a fake save file as initial data for savedata editor, and for
gamedata (wow i found a usage)
constrain eventwork editor to struct variable types (uint, int, etc),
thus preventing null assignment errors
With the approaching games, PKM sprites are a different size from the 3DS era (as already hinted by LGPE, which has 56x68). It'll be a little easier to manage with this portion of the library walled off from the rest of the codebase.
Eventually the net46 target will use fody or something to merge in these extra dependency dll's automatically to not disturb the usual exe/dll experience.
