Constructor & Destructor Documentation

◆ ResourceManager()

Sci::ResourceManager::ResourceManager ( const bool detectionMode = false )

Creates a new SCI resource manager.

Member Function Documentation

◆ init()

void Sci::ResourceManager::init ( )

Initializes the resource manager.

◆ addAppropriateSources()

void Sci::ResourceManager::addAppropriateSources ( )

Adds all of the resource files for a game

◆ addAppropriateSourcesForDetection()

void Sci::ResourceManager::addAppropriateSourcesForDetection ( const Common::FSList & fslist )

Similar to the function above, only called from the fallback detector

◆ findResource()

Resource* Sci::ResourceManager::findResource	(	ResourceId	id,
		bool	lock
	)

Looks up a resource's data.

Parameters

id	The resource type to look for
lock	non-zero iff the resource should be locked

Returns: The resource, or NULL if it doesn't exist

Note: Locked resources are guaranteed not to have their contents freed until they are unlocked explicitly (by unlockResource).

◆ unlockResource()

void Sci::ResourceManager::unlockResource ( Resource * res )

Unlocks a previously locked resource.

Parameters

res	The resource to free

◆ testResource()

Resource* Sci::ResourceManager::testResource ( const ResourceId & id ) const

Tests whether a resource exists.

This function may often be much faster than finding the resource and should be preferred for simple tests. The resource object returned is, indeed, the resource in question, but it should be used with care, as it may be unallocated. Use scir_find_resource() if you want to use the data contained in the resource.

Parameters

id	Id of the resource to check

Returns: non-NULL if the resource exists, NULL otherwise

◆ listResources()

Common::List<ResourceId> Sci::ResourceManager::listResources	(	ResourceType	type,
		int	mapNumber = `-1`
	)

Returns a list of all resources of the specified type.

Parameters

type	The resource type to look for
mapNumber	For audio36 and sync36, limit search to this map

Returns: The resource list

◆ hasResourceType()

bool Sci::ResourceManager::hasResourceType ( ResourceType type )

Returns if there are any resources of the specified type.

◆ addNewGMPatch()

void Sci::ResourceManager::addNewGMPatch ( SciGameId gameId )

Adds the appropriate GM patch from the Sierra MIDI utility as 4.pat, without requiring the user to rename the file to 4.pat. Thus, the original Sierra archive can be extracted in the extras directory, and the GM patches can be applied per game, if applicable.

◆ findSierraGameId()

Common::String Sci::ResourceManager::findSierraGameId ( )

Finds the internal Sierra ID of the current game from script 0.

◆ findGameObject()

reg_t Sci::ResourceManager::findGameObject ( const bool addSci11ScriptOffset )

Finds the location of the game object from script 0.

Parameters

addSci11ScriptOffset Adjust the return value for SCI1.1 and newer games. Needs to be false when the heap is accessed directly inside findSierraGameId().

◆ convertResType()

ResourceType Sci::ResourceManager::convertResType ( byte type )

Converts a map resource type to our type

Parameters

sciType The type from the map/patch

Returns: The ResourceType

◆ addPatchDir()

ResourceSource* Sci::ResourceManager::addPatchDir ( const Common::Path & path )

protected

Add a path to the resource manager's list of sources.

Returns: a pointer to the added source structure, or NULL if an error occurred.

◆ addSource()

ResourceSource* Sci::ResourceManager::addSource ( ResourceSource * source )

protected

Adds a source to the resource manager's list of sources.

Parameters

source The new source to add

Returns: A pointer to the added source structure, or NULL if an error occurred.

◆ addExternalMap()

ResourceSource* Sci::ResourceManager::addExternalMap	(	const Common::Path &	filename,
		int	volume_nr = `0`
	)

protected

Add an external (i.e., separate file) map resource to the resource manager's list of sources.

Parameters

filename	The name of the volume to add
volume_nr	The volume number the map starts at, 0 for <SCI2.1

Returns: A pointer to the added source structure, or NULL if an error occurred.

◆ scanNewSources()

void Sci::ResourceManager::scanNewSources ( )

protected

Scans newly registered resource sources for resources, earliest addition first.

Parameters

detected_version Pointer to the detected version number, used during startup. May be NULL.

Returns: One of SCI_ERROR_*.

◆ versionDescription()

const char* Sci::ResourceManager::versionDescription ( ResVersion version ) const

protected

Returns a string describing a ResVersion.

Parameters

version The resource version

Returns: The description of version

◆ getVolumeFile()

Common::SeekableReadStream* Sci::ResourceManager::getVolumeFile ( ResourceSource * source )

protected

All calls to getVolumeFile must be followed with a corresponding call to disposeVolumeFileStream once the stream is finished being used. Do NOT call delete directly on returned streams, as they may be cached.

◆ detectMapVersion()

ResVersion Sci::ResourceManager::detectMapVersion ( )

protected

— Resource map decoding functions —

◆ readResourceMapSCI0()

int Sci::ResourceManager::readResourceMapSCI0 ( ResourceSource * map )

protected

Reads the SCI0 resource.map file from a local directory.

Parameters

map The map

Returns: 0 on success, an SCI_ERROR_* code otherwise

◆ readResourceMapSCI1()

int Sci::ResourceManager::readResourceMapSCI1 ( ResourceSource * map )

protected

Reads the SCI1 resource.map file from a local directory.

Parameters

map The map

Returns: 0 on success, an SCI_ERROR_* code otherwise

◆ readAudioMapSCI11()

int Sci::ResourceManager::readAudioMapSCI11 ( IntMapResourceSource * map )

protected

Reads SCI1.1 audio map resources.

Parameters

map The map

Returns: 0 on success, an SCI_ERROR_* code otherwise

◆ readAudioMapSCI1()

int Sci::ResourceManager::readAudioMapSCI1	(	ResourceSource *	map,
		bool	unload = `false`
	)

protected

Reads SCI1 audio map files.

Parameters

map	The map
unload	Unload the map instead of loading it

Returns: 0 on success, an SCI_ERROR_* code otherwise

◆ readResourcePatches()

void Sci::ResourceManager::readResourcePatches ( )

protected

— Patch management functions — Reads patch files from a local directory.

◆ isBlacklistedPatch()

bool Sci::ResourceManager::isBlacklistedPatch ( const ResourceId & resId ) const

protected

Determines whether or not a patch file matching the given resource ID should be ignored when processing patches.

◆ readWaveAudioPatches()

void Sci::ResourceManager::readWaveAudioPatches ( )

protected

Process wave files as patches for Audio resources.

◆ hasOldScriptHeader()

bool Sci::ResourceManager::hasOldScriptHeader ( )

protected

Process AIFF files as patches for Audio resources. Applies to all versions before 0.000.395 (i.e. KQ4 old, XMAS 1988 and LSL2). Old SCI versions used two word header for script blocks (first word equal to 0x82, meaning of the second one unknown). New SCI versions used one word header. Also, old SCI versions assign 120 degrees to left & right, and 60 to up and down. Later versions use an even 90 degree distribution.

◆ getMacExecutableName()

Common::Path Sci::ResourceManager::getMacExecutableName ( ) const

Returns the file name of the game's Mac executable.
