GameScene
Subsystem
Official name Yes
Description Handles the main loop and stages
Init function Switch 1.5.0: 0x71007D1DD8
Wii U 1.5.0: ???
Debug only No

GameScene is a critical subsystem that is responsible for core functionality such as initialising other components, creating stages (world, title screen, etc.) and handling the game's main loop.

Unlike most other subsystems, GameScene is not a singleton: it is a member of the uking::frm::System structure[1].

Init

Initial state

The initial state the game launches into is determined by GameScene[2]. 

const bool isFirstLaunch = SaveSystem::sInstance->isFirstLaunch();
State* state = isFirstLaunch ? &state_NewSave : &state_LunchTitle;

if ( aocManager::sInstance && aocManager::sInstance->flags & 2 )
  nn::err::ShowUnacceptableAddOnContentVersionError();

const bool isDemo = E3Mgr::sInstance && E3Mgr::sInstance->isDemoMode();
if (isDemo)
  state = &state_LunchTitle;

if (!isDemo && isFirstLaunch)
  sIsFirstNonDemoLaunch = 1;

StateMachine::changeState(&this->stateMachine, state);

States

Note: when the Indoor stage binder is initialised and if the map name changes, a "dungeon" telemetry report is emitted with "leave" or "enter" as the event name and the old/new map name as additional data[4].

StageMgr

StageSelect

StageTransition

Entered before stage generation starts and after Fade (loading screen) has been initialised and made visible. This state machine state is a noop.

LunchTitle

LunchTitle (sic) is entered when the game is launched. The internal state string is "TitleMenu" or (in demo mode) "2nd".

NewSave

Entered on the first boot or when the new game option is selected. The associated state string is "初回シーケンス" ("initial sequence").

PatchError

Main loop

Three GameScene functions are called in a row from RootTask (see Executable) after initialisation has completed, i.e. in the game's main loop. (Note: these 3 names are unofficial.)

Stage generation

  • Terrain::sInstance->flags |= 0x180u
  • Step 0
    • Reload Title.pack if the stage that needs to be generated is TitleStage (3)[5].
    • StageSelect checks[6]
  • Step 1
    • If a pack was loaded by DungeonPackMgr, wait for DungeonPack loading to finish[7] and switch active pack to the dungeon pack.
  • Step 2
    • If the stage to load is TitleStage, wait for TitlePack loading to finish[8] and switch active pack to the title pack.
  • Step 3: start stage generation[9]
    • PlacementMgr
    • ActorSystem::sInstance->field_13A = 0
    • Update current map flags (e.g. sIsDungeon)
    • Clear BaseProcMgr ActorCreate queue[check]
    • Create uking::Stage::ForBaseProcDual heap (if not already done), which will be used for actors, ActorCreator and BaseProcMgr
    • ActorSystem::sInstance->field_139 = 0
    • If the state string starts with 初回シーケンス, MainField, GameTestField, GameTestField2, AocField, CDungeon, MainFieldDungeonStage, GameTestDungeon, MonolithTestDungeon, SrdTestDungeon, MarioClubTestDungeon, TestField, 研修用, MonolithTest100enemy, MinimumField, or ActorViewer, call GameScene::startBgProcessing (0x71007B2054)
    • If "new save" was selected, initialize PauseMenuDataMgr data
    • If the stage to load is TitleStage, load Layout/Title.blarc for ui::LayoutResourceMgr.
    • If "new save" was selected and the awakening demo hasn't been played since the game was launched[10], ask EventMgr to call Demo169_0.
    • Some PhysicsMemSys stuff (0x71007ADBE0).
  • Step 4
    • Wait for completion of Title BG processing (20% of the loading bar)
    • uiManager (0x71007ACD04)
    • Initialize StatisticsMgr paths depending on current map type.
    • Update aoc2's mapType and mapName fields.
  • Step 5
    • PhysicsMemSys stuff (0x71007ACDB8, 0x71007ACDC0, 0x71007ACDD0)
    • BaseProcMgr: request "PreDelete" actors[11]
    • BaseProcMgr: stop ActorCreate initializer thread and clean up internal state[check]
    • agl::lyr::Renderer and Graphics stuff
  • Step 6
    • Load env.genvb binary (gsys::ModelSceneEnv::clearImpl + loadBinaryImpl)
    • If the stage binder type is 0, 1 or 2 (OpenWorldStage, IndoorStage or MainFieldDungeonStage):
      • Set loading progress to 40%.
      • Graphics stuff, again
      • OnUiActorMgr
      • GameScene::loadTera (on a separate thread)
  • Step 7
    • If the stage binder type is 0, 1 or 2 (OpenWorldStage, IndoorStage or MainFieldDungeonStage):
      • Wait for Tera to load[12]
  • Step 8
    • ...
    • Wait for Tera to generate collision
    • ...
  • Step 9
