## 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).
Closes#3133
not an ideal solution, but the encounter matching API is kinda limited in deferred-invalid vs deferred-notIdeal.
probably need to unify the match logic and generators so they can cache one secondary-check invalid
See the EncounterSlotDumper with the memoization logic & json tree listing.
Simplifies things a lot, and improves checking speed. Unreachable trees are now treated the same as no-trees maps.
ez 1.5KB reduction in file size :P
Remove gen3 egg location hashset; only paths that reach it are for hatched eggs or current breed-eggs. Check breed eggs with the singular met location.
Simplify some logic flow
This only matches the weather table with the Pokemon and does not fully
account for whether a location can spawn a particular weather.
Additional minor changes:
- Adds ScriptedNoMarks to Regis and Glimwood Tangle static encounters
- Corrects a few version-specific Pokemon such as Ludicolo/Shiftry
- Removes erroneous encounters such as Milotic in East/West Lake Axewell
- Removes an unused Motostoke Stadium encounter
clean:
if (!logical) return;
Existing logic had methods named to return true if fail, now method checks for passing, thus the logic now follows the above pattern.
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.
Metagross collision with wild beldum
deferral API is kinda crude, hence these janky workarounds. Was originally intended to hold onto close matches when there's no more possible matches to check.
I think a priority-deferral while only retaining a single encounter bad (instead of a list of retries) may work better than the current setup, but that would require more abstraction
Transporter remaps certain locale specific chars depending on the source ROM's version.
Since VC can trade between languages, there are 2 Spanish in-game trades that have glyphs subject to remapping, if it's transferred from a French game.
If the spanish trade is transferred from a french game, it must match the mutated string.
ty @Lusamine & helpers :D
Slap in friend safari at the end during object construction; saves about 1KB of allocation on startup (lol)
Change internal array types to match object types, similar to other encounter-generation definitions.
I think this was a PKHeX issue that went unnoticed; originally, we didn't include the Á and Í chars in the dictionary.
I checked the transporter code:
The app maintains the international & japanese character tables, and depending on the ROM language, it may change a char to the language-specific entry. Refer to Bulbapedia's notes on the char tables for different languages:
https://bulbapedia.bulbagarden.net/wiki/Character_encoding_in_Generation_II
However, none of these char-changes are able to be reached with a legal char.
Á and Í (only accessible from the Spanish in-game trades) and the german 0xC0 && z <= 0xC6 chars are already in the international table. Every single difference in the VC1/VC2 table is an un-enterable char.
tl;dr -- all possible char codes are transferred fine with the VC2 table without extra language logic. We just keep out any inaccessible char (replaced with space).
Move form-info logic from FormConverter to AltFormInfo; now FormConverter is entirely form=>string[]
Add a bunch of xmldoc
Make pogo no-end-date cmp agaisnt UTCnow rather than local now.
Event Move special encounters are yielded after static encounters by the generator, so this iterator-picker will never behave as originally intended.
Since the encounter generator works fine for these events in its current form, we can just remove it. If we need to prefer GB era events before static, then we'd reinstate the priority and move the GenerateGBEvents before the static yielder.
bla bla bla this is just a cleanup from old preference code where we wanted to recognize the encounter as an event/trade as they're more recognizable. We just want to track the progress of the iterator so that g1/g2 follow a merged yielding order
Adds Nickname checks, thanks @ShadowMario3 for grabbing these into separate text files from Bulbapedia.
I reordered all the encounters to match Bulbapedia; each level is denoted if different if it can be sourced from RBY.
Extract common abstract class for GO transferred encounters
Clamp minlevel instead of met level
Add optional parameter for GO IV randomization
Update go legality binaries with latest
PKHeX.Core now accepts generated pkl binaries from PoGoEncounterTool (PGET).
Refer to pporg's repo. This will be treated like event data; occasionally updated.
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!
Sure it's nice to cache a valid array, but the amount of logic was small enough that it can be done with 10 lines of code rather than at the end of each verification method.
Reduces parameter passing & removes 1 field from the info object, as relearn suggestions are only done rarely after legality checking.
Allows for a simpler api surface (pkm, encounter) rather than a bigger object reference

The game uses 0x5E if 0x5A+everstone, otherwise it uses 0x58
For determining the seed species-form, we want to use everstone breeds as that resolves to the correct species-form values.

Handle yielding in the moveset generator as well
Future commits will trim down unused values/abstractions; probably can get all the stadium stuff handled innately
Revises the tradeback status to remove any index that could have been sourced from egg moves instead.
really should refactor this TradebackStatus away, but Move validation still remains one of the un-refined parts of the legality checks :P
Introducing a new PKM format: SK2
Split ICaughtData2 off of PK2 so it can be shared with SK2 when type-checks occur

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.
Change Ability array to IReadOnlyList, add method to check ability index in personal data
Suppress some message warnings
Change EvolutionChain short-circuit for VC to jump from gen6 directly down to gen2. There aren't any notradeback 1 situations, so a notradeback1 will always start with g=1, so no need for the other if-continue.
Simplify pk5 conversion
Gen1: all are Trade1 objects, and all get the values set; just set the value in the object initializer
Gen2: all are Trade2 objects, set the same version
Gen2 all static encounters already have a version marked. Only thing remaining is to set the language.
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
Still some pending stuff like bad mystery gifts
gen2 static encounters on g/s applying met level and not location
gen6 ralts trade (no nickname) being flagged as nicknamed when it shouldn't
gen4 manaphy egg not having a hatch location (worked fine if you transferred it up)
gen3 antishiny gifts not setting their PIDs (jirachi WC3)
gen5 N's pkm gifts setting the wrong nature
gen3 unown not being generated correctly, cosplay pikachu being allowed form0, non-BugCatchingContest no longer require Sport ball, oras dexnav marill now uses the azurill eggmove table
Remove RibbonWishing as property, just calc on the fly since it's a single case
Update type info for vc transfer to indicate it's an es7
Split up dreamworld encounters as intended, fix logic lol
precompute result size
set Gen5 as lumped group for common encounters
remove linq usage (besides Sum call, whatever)
GetEncounters now only filters the in-game static encounters rather than the dreamworld too, as those are already filtered by separate arrays.
Check successive move slots after the current index rather than doing a count eq >= 2.
Flag all empty slots prior to a filled move slot, rather than flagging a full slot as invalid because "empty move".
* 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
Check egg encounter for state rather than re-deriving some properties on the fly
Only check memories if memories are exposed
Remove debug assert (not always true?)
GO Fest 2020 made Alolan Marowak available in wild spawns, and further testing has proved that Raid/Research PKM can be downleveled to 15 after trading to low-level accounts.
This'll probably end up being deprecated in the future when we have GO->HOME transfer checks, in addition to IV checking.
verify relearn: move split check before method call
movelist: don't capture pkm in local method; meowstic ID
pkm: flip argument for easier understanding
Results in a little more code, but each path is less tangled
simplify some expressions
remove RBDragonair content in favor of a strict filter for catch rate
Move gen1 trade trainer names to stringconverter, since pk1/pk2 shouldn't refer to legality classes
Some zone names were mislabeled in pkNX -- Staryu are not scripted encounters!
Remove altform specific moves from distro/static Rotom, which would erroneously allow illegal mismatches (e.g. Hydro Pump Rotom-1); thanks Abyzab (Discord)!
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)
vs -> chain (clarity on what it is; an evolution chain, rather than e.v.o.s - vs)
Clamp origin chain for transferred where we can use the max origin level
Can lose gmax flag if its current species is able to eat soup, or its origin species could eat soup
this handles stuff like charmander->charizard, as charmeleon would not pass
hopefully there's never a mid-stage evo that has a gmax form, and its final evo doesn't... (don't get any ideas, gamefreak)
invert ability index favoring so that the first ability index is most favored
ability num:
-1=>0/1/2
0=>0/1,
1=>0
2 =>1
4=>2
Ability Type:
0,1,2=>0,1,2
3=>0/1
4=>0/1/2
Should probably get rid of AbilityNumber definition usage but it's so entwined in the trade/static definitions...

remove GetMinimalLevel override, as it's doing the same thing as LevelMin. When regenerating the pkm, we aren't doing anything downlevel related.
Downleveled shared nest can't go below 20
Downleveled self nest can only happen for 1 or 3 badges and certain star counts, and the result can't be shiny
Encounter Generator stops yielding if anything was yielded (assumes things that are static encounters can't have anything else that would match).
DexNav boosts the wild level (from 25/27) up to the same level 30 of the static encounter.
Thanks @KR1dude !

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.
just need to get all evo chains possible
fetching a GO leafeon, need to reverse leafeon->eevee, but the LGPE evo chains don't know about leafeon
works fine now
Bye bye invalid drilbur, nice meme GF
The first rotom2 in Shield had its moves changed too. Keep that rotom-2 since Discharge can't be learned at that level.
since sw and sh have the same drilbur, it moves from sw -> common.

Mewtwo encounter has been added; awaiting confirmation that it can be captured (assumed yes)
Gen1 starters can be captured in beast ball in gen7 (scan), so nothing changes for ball legality.
Traded eggs in gen4 can have from any game (since version isn't updated on hatch).
Use the hashsets, and remove the incorrect array. The incorrect array allowed stuff like Pokéwalker to be a "valid met location", hah.
