GameScene

Revision as of 15:47, 13 October 2018 by imported>Leoetlino

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);

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.)
