Member Function Documentation

◆ run()

Common::Error Drascula::DrasculaEngine::run ( )

overrideprotectedvirtual

Initialize the engine and start its main loop.

Returns: kNoError on success, otherwise an error code.

Implements Engine.

◆ hasFeature()

bool Drascula::DrasculaEngine::hasFeature ( EngineFeature f ) const

overridevirtual

Determine whether the engine supports the specified feature.

Reimplemented from Engine.

◆ syncSoundSettings()

void Drascula::DrasculaEngine::syncSoundSettings ( )

overridevirtual

Notify the engine that the sound settings in the config manager might have changed and that it should adjust any internal volume (and other) values accordingly.

The default implementation sets the volume levels of all mixer sound types according to the config entries of the active domain. When overwriting, call the default implementation first, then adjust the volumes further (if required).

Note: When setting volume levels, respect the "mute" config entry.; The volume for the plain sound type is reset to the maximum volume. If the engine can associate its own value for this type, it needs to overwrite this member and set it accordingly.

Reimplemented from Engine.

◆ loadGameState()

Common::Error Drascula::DrasculaEngine::loadGameState ( int slot )

overridevirtual

Load a game state.

Parameters

slot	The slot from which a save state should be loaded.

Returns: kNoError on success, otherwise an error code.

Reimplemented from Engine.

◆ canLoadGameStateCurrently()

bool Drascula::DrasculaEngine::canLoadGameStateCurrently ( Common::U32String * msg = nullptr )

overridevirtual

Indicate whether a game state can be loaded.

Parameters

msg	Optional pointer to message explaining why it is disabled

Reimplemented from Engine.

◆ saveGameState()

Common::Error Drascula::DrasculaEngine::saveGameState	(	int	slot,
		const Common::String &	desc,
		bool	isAutosave = `false`
	)

overridevirtual

Save a game state.

Parameters

slot	The slot into which the save state should be stored.
desc	Description for the save state, entered by the user.
isAutosave	Expected to be true if an autosave is being created.

Returns: kNoError on success, otherwise an error code.

Reimplemented from Engine.

◆ canSaveGameStateCurrently()

bool Drascula::DrasculaEngine::canSaveGameStateCurrently ( Common::U32String * msg = nullptr )

overridevirtual

Indicate whether a game state can be saved.

Parameters

msg	Optional pointer to message explaining why it is disabled

Reimplemented from Engine.
