🧬 General 🧬

Added

  • Added migration script README by @Bassoonian in #4719

  • Customizable Frontier Pokémon sets by @ghoulslash in #4313

    • FacilityMon has been removed in favor of using regular TrainerMon.
    • Removed BATTLE_FRONTIER_ITEM_x item constants in favor of using regular ITEM_x constants.
    • New CreateFacilityMon to handle duplicated code.
      • Added FLAG_FRONTIER_MON_FACTORY that replaces Return for Frustration and sets frienship to 0. Used in the Battle Factory.
    • Converted data in src/data/battle_frontier/battle_frontier_mons.h and src/data/battle_frontier/battle_tent.h, for example:
      • .itemTableId = BATTLE_FRONTIER_ITEM_CHOICE_BAND, -> .heldItem = ITEM_CHOICE_BAND,
      • .evSpread = F_EV_SPREAD_SPEED | F_EV_SPREAD_ATTACK, -> .ev = TRAINER_PARTY_EVS(0, 252, 0, 252, 0, 0),
    • Migration script available in migration_scripts/egg_move_refactor.py by @AlexOn1ine in #5040
  • Added documentation to STATIC_ASSERTS used by the BoxPokemon after 1.8.0 by @pkmnsnfrn in #4294

  • Competitive-formatted parties by @mrgriffin in #3545

    • Can be disabled by setting COMPETITIVE_PARTY_SYNTAX to FALSE in include/config/general.h. If migrating from 1.8, remove the first and last lines from src/data/trainers.h (const struct Trainer gTrainers[] = { and }; respectively).
    • Introduces trainerproc, a tool which converts Competitive-formatted parties into Trainer Control-formatted parties.
    • If you made custom changes to the following files and want to use this new format, Do not accept the incoming changes for them. Instead, use the migration script present in migration_scripts/convert_parties.py:
      • src/data/trainers.h
      • src/data/trainer_parties.h
      • src/data/battle_partners.h
      • src/data/partner_parties.h
    • Before: 
      static const struct TrainerMon sTestParty1[] =
{
    {
        .species = SPECIES_WOBBUFFET,
        .ball = ITEM_MASTER_BALL,
        .ability = ABILITY_TELEPATHY,
        .friendship = 42,
        .gender = TRAINER_MON_FEMALE,
        .heldItem = ITEM_ASSAULT_VEST,
        .isShiny = TRUE,
        .iv = TRAINER_PARTY_IVS(25,26,27,28,29,30),
        .ev = TRAINER_PARTY_EVS(252, 0, 0, 252, 4, 0),
        .lvl = 67,
        .moves = {MOVE_AIR_SLASH, MOVE_BARRIER, MOVE_SOLAR_BEAM, MOVE_EXPLOSION},
        .nature = NATURE_HASTY,
        .nickname = COMPOUND_STRING("Bubbles")
    },
    {
        .species = SPECIES_WOBBUFFET,
        .ability = ABILITY_SHADOW_TAG,
        .lvl = 5,
    },
};

static const struct Trainer sTestTrainer1 =
{
    .trainerName = _("Test1"),
    .party = TRAINER_PARTY(sTestParty1),
};
      After: 
      === 0 ===

    • You can add comments by using // or /* ... */, like in C.
    • You're allowed to write SPECIES_PIKACHU instead of Pikachu (etc etc) if you want.
    • In addition to the migration script described above, you can add the following to at the top of the src/data/trainers.party file to change how the tool interprets the file:
      • #pragma trainerproc ivs explicit — requires an IVs: line for every Pokémon instead of defaulting to 31s.
      • #pragma trainerproc ivs <IVs> — changes the default IVs.
      • #pragma trainerproc level explicit — requires a Level: line for every Pokémon instead of defaulting to 100.
      • #pragma trainerproc level <level> — changes the default level.
      • During the merge you could choose to keep your original src/data/trainers.h and src/data/trainer_parties.h and then run the conversion script to update the src/data/trainers.party, make, then check in all three files. Alternatively don't run the conversion script and turn off COMPETITIVE_PARTY_SYNTAX in include/config.h.
    • Added synonyms for competitive/CFRU species defines, eg:
      • SPECIES_PONYTA_GALAR for SPECIES_PONYTA_GALARIAN
      • SPECIES_MAUSHOLD_FOUR for SPECIES_MAUSHOLD_FAMILY_OF_FOUR
      • SPECIES_CHARIZARD_GMAX for SPECIES_CHARIZARD_GIGANTAMAX
      • And so.
    • TODO:
      • Support Hidden Power: to set IVs appropriate for a particular Hidden Power type.
      • Consider case-insensitivity in the parser.
    • Cleanup and bugfixes:
  • Added OW_PC_MOVE_ORDER config to use future generation's menu order for the Pokémon Storage System by @pkmnsnfrn and @AsparagusEduardo in #4348
    • GEN_1/2/3: Widthraw -> Deposit -> Move.
    • GEN_4/5/6_XY: Deposit -> Widthraw -> Move.
    • GEN_6_ORAS/7/8/9: Move -> Deposit -> Widthraw.
  • Added OW_HIDE_REPEAT_MAP_POPUP config that doesn't show the Map Popup when transitioning bewteen maps within the same Map Section by Anon822 from Pokécommunity and @pkmnsnfrn in #4370
  • Multiple Fishing Enhancements by @ghoulslash and @pkmnsnfrn in #4343
    • Added I_FISHING_CHAIN config to enable XY's chain fishing.
    • Added I_FISHING_PROXIMITY config to enable XY's proximity mechanic, where fishing away from NPCs increases the chance of a Pokémon being hooked.
    • Added I_FISHING_MINIGAME config to change between minigame versions.
      • GEN_1/2 will not require a minigame, and instead automatically hook the Pokémon.
      • All other settings use RSE's minigame. FRLG/Gen4+'s minigame will be implemented in the future.
    • Cleanup and bugfixes:

  • Full official GF names for species/items/moves/types by @mrgriffin, @ZnogyroP and @cfmnephrite in #4241

    • 8-character type names.
    • 12-character Pokémon names (and nicknames)
    • 16-character Move names.
    • 20-character item names.
    • This is done by introducing 3 new fonts that automatically change the size of the name in vanilla interfaces:
      • FONT_NARROWER, FONT_SMALL_NARROWER and FONT_SHORT_NARROW.
    • If the hack has changed fonts—e.g. to the FrLg ones—then they probably want to create their own versions of the new fonts.
    • If the hack has introduced more UIs that render names they probably want to use GetFontIdToFit—see this PR's changes for examples of that.
    • If the hack has introduced names in list menus they can use .fontIdMayNarrow = TRUE on the list template.
    • Types, species, moves, and items all have individual commits which enable support in the UI and turn on longer names by default. These can be reverted by downstream projects if they really want to.
    • Cleanup
  • Added OW_PC_RELEASE_ITEM config that gives back items from released Pokémon by @Bassoonian in #4577
    • If the bag is full, the item is lost, however.
    • Cleanup by @Bassoonian in #4844
  • Added P_EGG_CYCLE_LENGTH config that updates the amount of steps required to complete an egg cycle by @Bassoonian in #4596
  • Added trainerbattle_two_trainers macro to trigger a 1 player vs 2 NPC battle by @aarant and @AlexOn1ine in #4741
  • Added createmon Script Command and macro by @ghoulslash in #4688
    • This allows to set up wild enemy parties with the same versatility as givemon (IVs, EVs, abilities, moves, etc).
  • Added setwilddoubleflag macro to set sIsScriptedWildDouble and allow 2 player vs 1 enemy wild battles by @ghoulslash in #4688
  • Added support for multiple Roaming Pokémon at once by @Bassoonian in #4762
    • By default, ROAMER_COUNT is set to 1 to keep save compatibility. Increase it to add more roamers (though this breaks saves).
  • Added OW_IGNORE_EGGS_ON_HEAL, which makes it such that eggs are not counted in the Pokémon Center's heal animation by @ghoulslash @pkmnsnfrn in #4888
  • Added support for fake RTC by Anon822 from PokéCommunity and @pkmnsnfrn in #4910
    • When OW_USE_FAKE_RTC is TRUE, time runs at a different rate from real time, like in Legends: Arceus or Scarlet and Violet.
    • Use OW_ALTERED_TIME_RATIO to set the amount of "time" passing every 60 frames (1 real time second):
      • GEN_8_PLA: 1 minute.
      • GEN_9: 20 seconds.
      • All other settings make the game synced with real life.
    • You may also set a flag to pause the RTC (OW_FLAG_PAUSE_TIME), and the script commands pausefakertc, resumefakertc and togglefakertc by @pkmnsnfrn in #4954
    • Cleanup by @Bassoonian in #4965
  • Added B2W2-style map pop-Ups by @ravepossum, @nielsmittertreiner and @pkmnsnfrn in #4396
    • Change OW_POPUP_GENERATION to GEN_5 to switch existing map popups.
    • You may choose between Black or White themes via OW_POPUP_BW_COLOR (OW_POPUP_BW_COLOR_BLACK or OW_POPUP_BW_COLOR_WHITE).
    • You may choose to display the current time in the pop-up using OW_POPUP_BW_TIME_MODE.
      • OW_POPUP_BW_TIME_NONE: Disables time in pop-up.
      • OW_POPUP_BW_TIME_12_HR: Shows 12-hour time in pop-up
      • OW_POPUP_BW_TIME_24_HR: Shows 24-hour time in pop-up
    • You may enable alpha blending via OW_POPUP_BW_ALPHA_BLEND (mainly designed around the Black theme).
    • Cleanup by @AsparagusEduardo in #4752

    • TYPE_NONE duplicates graphics from TYPE_MYSTERY due to limitations with graphics_file_rules.mk.
    • Damage Categories for B_PHYSICAL_SPECIAL_SPLIT's pre-Gen4 setting can now be specified in this gTypesInfo's damageCategory field instead of depending on the type's order.

  • Applied the Pokémon Sprite Visualizer name officially by @Bassoonian in #4745

✨ Feature Branches ✨

merrp/aarant's Followers

Changes from the original branch

  • Follower Pokémon can be enabled using the OW_FOLLOWERS_ENABLED config.
  • Pokémon NPCs can be added to a map independently from the Followers config. Keep in mind, this requires OW_POKEMON_OBJECT_EVENTS to be enabled in order to add the graphics to the ROM.
    • Eg: use OBJ_EVENT_GFX_SPECIES(CHARIZARD) where the graphic ID would go (OBJ_EVENT_GFX_SPECIES_SHINY() for shiny version).
    • May also use OBJ_EVENT_GFX_SPECIES_SHINY(CHARIZARD) to make them shiny by @AsparagusEduardo in #5049
  • Moved original configs from include/constants/event_objects.h to include/config/overworld.h and renamed them:

  • Follower data has been moved to gSpeciesInfo
    • Their palettes are separate from the battle sprite palettes
      • Can be enabled using OW_FOLLOWERS_SHARE_PALETTE, but requires manual sprite adjustements. For now, it's recommended to keep this FALSE. (They don't use much space anyway)
  • Updated GetTypeEffectiveness used by follower messages to account for new abilities with type immunities.
  • Cleaned up code style to match pret/expansion's.
  • Reverted Regi's sprite to vanilla's.
