Member Function Documentation

run()

Common::Error Crab::CrabEngine::run ( )

overrideprotectedvirtual

Initialize the engine and start its main loop.

Returns

kNoError on success, otherwise an error code.

Implements Engine.

initializePath()

void Crab::CrabEngine::initializePath ( const Common::FSNode &  gamePath )

overridevirtual

Initialize SearchMan according to the game path.

By default, this adds the directory in non-flat mode with a depth of 4 as priority 0 to SearchMan.

Parameters

gamePath

The base directory of the game data.

Reimplemented from Engine.

getGameId()

Common::String Crab::CrabEngine::getGameId

(

)

const

Returns the game Id

getRandomNumber()

uint32 Crab::CrabEngine::getRandomNumber ( uint  maxNum )

inline

Gets a random number

hasFeature()

bool Crab::CrabEngine::hasFeature ( EngineFeature  f ) const

inlineoverridevirtual

Determine whether the engine supports the specified feature.

Reimplemented from Engine.

canLoadGameStateCurrently()

bool Crab::CrabEngine::canLoadGameStateCurrently ( Common::U32String *  msg = nullptr )

inlineoverridevirtual

Indicate whether a game state can be loaded.

Parameters

msg	Optional pointer to message explaining why it is disabled

Reimplemented from Engine.

canSaveGameStateCurrently()

bool Crab::CrabEngine::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.

syncGame()

Common::Error Crab::CrabEngine::syncGame

(

Common::Serializer &

s

)

Uses a serializer to allow implementing savegame loading and saving using a single method

saveGameState()

Common::Error Crab::CrabEngine::saveGameState ( int  slot, const Common::String &  desc, bool  isAutosave  )

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.

loadGameState()

Common::Error Crab::CrabEngine::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.

syncSoundSettings()

void Crab::CrabEngine::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.
