GameScene

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.

GameScene

Subsystem
Official name	Yes
Description	Handles the main loop and stages
Init function	Switch 1.5.0: 0x71007D1DD8 Wii U 1.5.0: ???

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

Initial state

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

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

StageTransition

Entered from 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").

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.)
