Member Function Documentation

run()

Common::Error Sword2::Sword2Engine::run ( )

overrideprotectedvirtual

Initialize the engine and start its main loop.

Returns

kNoError on success, otherwise an error code.

Implements Engine.

hasFeature()

bool Sword2::Sword2Engine::hasFeature ( EngineFeature  f ) const

overrideprotectedvirtual

Determine whether the engine supports the specified feature.

Reimplemented from Engine.

syncSoundSettings()

void Sword2::Sword2Engine::syncSoundSettings ( )

overrideprotectedvirtual

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.

pauseEngineIntern()

void Sword2::Sword2Engine::pauseEngineIntern ( bool  pause )

overrideprotectedvirtual

Actual implementation of pauseEngine by subclasses.

See also

Engine::pauseEngine

Reimplemented from Engine.

saveGameState()

Common::Error Sword2::Sword2Engine::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 Sword2::Sword2Engine::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.

loadGameState()

Common::Error Sword2::Sword2Engine::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 Sword2::Sword2Engine::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.

getSaveStateName()

Common::String Sword2::Sword2Engine::getSaveStateName ( int  slot ) const

overridevirtual

Generate the savegame filename.

Reimplemented from Engine.
