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);

StageMgr

StageSelect

StageTransition

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 (GameScene @ 0x720) 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.)
