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

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);
