Member Function Documentation

◆ run()

Common::Error Gnap::GnapEngine::run ( )

overrideprotectedvirtual

Initialize the engine and start its main loop.

Returns: kNoError on success, otherwise an error code.

Implements Engine.

◆ hasFeature()

bool Gnap::GnapEngine::hasFeature ( EngineFeature f ) const

overrideprotectedvirtual

Determine whether the engine supports the specified feature.

Reimplemented from Engine.

◆ saveGameState()

Common::Error Gnap::GnapEngine::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.

◆ loadGameState()

Common::Error Gnap::GnapEngine::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.
