virtual bool iLoader::GetAutoRegions

(

)

[pure virtual]

Get whether to load each file into a separate region.

virtual bool iLoader::Load	(	iDocumentNode *	node,
		iBase *&	result,
		iRegion *	region = 0,
		bool	curRegOnly = true,
		bool	checkDupes = false,
		iStreamSource *	ssource = 0,
		const char *	override_name = 0,
		iMissingLoaderData *	missingdata = 0
	)			[pure virtual]

Load a node.

This is a smart function that will try to recognize what kind of node it is. It recognizes the following types of nodes:

• 'world' node: in that case 'result' will be set to the engine.
• 'library' node: 'result' will be 0.
• 'meshfact' node: 'result' will be the mesh factory wrapper.
• 'meshobj' node: 'result' will be the mesh wrapper.

Returns false on failure.
Note! In case a world node is loaded this function will NOT clear the engine!
Note! In case a mesh factory or mesh object is loaded this function will not actually do anything checkDupes is true and the mesh or factory is already in memory (with that name). This function will still return true in that case and set 'result' to the correct object.
Note! Use SCF_QUERY_INTERFACE on 'result' to detect what type was loaded.

Parameters:

	node	is the node from which to read.
	result	will be set to the loaded result (see above).
	region	is 0 by default which means that all loaded objects are not added to any region. If you give a region here then all loaded objects will be added to that region.
	curRegOnly	is true by default which means that it will only find materials/factories/... from current region if that is given.
	checkDupes	if true then materials, textures, and mesh factories will only be loaded if they don't already exist in the entire engine (ignoring regions). By default this is false because it is very legal for different world files to have different objects with the same name. Only use checkDupes == true if you know that your objects have unique names accross all world files.
	ssource	is an optional stream source for faster loading.
	override_name	if this is given the the name of the loaded object will be set to that. This only works in case of meshfact, meshobj, and 3ds or md2 model.
	missingdata	is an optional callback in case data is missing. The application can then provide that missing data in some other way.

virtual bool iLoader::Load	(	iDataBuffer *	buffer,
		iBase *&	result,
		iRegion *	region = 0,
		bool	curRegOnly = true,
		bool	checkDupes = false,
		iStreamSource *	ssource = 0,
		const char *	override_name = 0,
		iMissingLoaderData *	missingdata = 0
	)			[pure virtual]

Load a file.

This is a smart function that will try to recognize what kind of file it is. It recognizes the following types of files:

• 'world' file: in that case 'result' will be set to the engine.
• 'library' file: 'result' will be 0.
• 'meshfact' file: 'result' will be the mesh factory wrapper.
• 'meshobj' file: 'result' will be the mesh wrapper.
• 3ds/md2 models: 'result' will be the mesh factory wrapper.

Returns false on failure.
Note! In case a world file is loaded this function will NOT clear the engine!
Note! In case a mesh factory or mesh object is loaded this function will not actually do anything checkDupes is true and the mesh or factory is already in memory (with that name). This function will still return true in that case and set 'result' to the correct object.
Note! Use SCF_QUERY_INTERFACE on 'result' to detect what type was loaded.

Parameters:

	buffer	is a buffer for the model contents.
	result	will be set to the loaded result (see above).
	region	is 0 by default which means that all loaded objects are not added to any region. If you give a region here then all loaded objects will be added to that region.
	curRegOnly	is true by default which means that it will only find materials/factories/... from current region if that is given.
	checkDupes	if true then materials, textures, and mesh factories will only be loaded if they don't already exist in the entire engine (ignoring regions). By default this is false because it is very legal for different world files to have different objects with the same name. Only use checkDupes == true if you know that your objects have unique names accross all world files.

	)			[pure virtual]

Load an image file.

The image will be loaded in the format requested by the engine. If no engine exists, the format is taken from the video renderer. If no video renderer exists, this function fails. You may also request an alternate format to override the above sequence. This version reads the image from a data buffer.

virtual csPtr<iImage> iLoader::LoadImage	(	const char *	Filename,
		int	Format = CS_IMGFMT_INVALID
	)			[pure virtual]

		const char *	fname,
		int	mode3d
	)			[pure virtual]

New Sound System: Load a sound file, create a stream and create a wrapper object for it.

Use LoadSoundStream() without mode3d parameter. The mode should be given at the time the stream is created later.

Parameters:

	name	of the sound.
	fname	is the VFS filename.
	mode3d	is one of CS_SND3D_DISABLE, CS_SND3D_RELATIVE, or CS_SND3D_ABSOLUTE.

virtual iTextureWrapper* iLoader::LoadTexture	(	const char *	Name,

		iTextureManager *	tm = 0,
		bool	reg = true,
		bool	create_material = true,
		bool	free_image = true
	)			[pure virtual]

Load a texture as with LoadTexture() above and register it with the engine.

This version reads the image from a data buffer.

Parameters:

	Name	The name that the engine will use for the wrapper.
	buf	Buffer containing the image file data.
	Flags	Accepts the flags described in ivideo/txtmgr.h. The texture manager determines the format, so choosing an alternate format doesn't make sense here. Instead you may choose an alternate texture manager.
	tm	Texture manager, used to determine the format the image is to be loaded in (defaults to CS_IMGFMT_TRUECOLOR if no texture manager is specified).
	reg	if true then the texture and material will be registered to the texture manager. Set 'register' to false if you plan on calling 'engine->Prepare()' later as that function will take care of registering too.
	create_material	if true then this function also creates a material for the texture.
	free_image	if true then after registration the loaded image will be removed immediatelly. This saves some memory. Set to false if you want to keep it. free_image is ignored if reg is false.

Load an image as with LoadImage() and create a texture handle from it.

This version reads the image from a data buffer.

Parameters:

	buf	Buffer containing the image file data.
	Flags	Accepts the flags described in ivideo/txtmgr.h. The texture manager determines the format, so choosing an alternate format doesn't make sense here. Instead you may choose an alternate texture manager.
	tm	Texture manager, used to determine the format the image is to be loaded in (defaults to CS_IMGFMT_TRUECOLOR if no texture manager is specified).
	image	Optionally returns a reference to the loaded image.

virtual iTextureWrapper* iLoader::LoadTexture	(	const char *	Name,
		const char *	FileName,

Parameters:

	Name	The name that the engine will use for the wrapper.
	FileName	VFS path to the image file to load.
	Flags	Accepts the flags described in ivideo/txtmgr.h. The texture manager determines the format, so choosing an alternate format doesn't make sense here. Instead you may choose an alternate texture manager.
	tm	Texture manager, used to determine the format the image is to be loaded in (defaults to CS_IMGFMT_TRUECOLOR if no texture manager is specified).
	reg	If true then the texture and material will be registered to the texture manager. Set 'register' to false if you plan on calling 'engine->Prepare()' later as that function will take care of registering too.
	create_material	If true then this function also creates a material for the texture.
	free_image	If true then after registration the loaded image will be removed immediatelly. This saves some memory. Set to false if you want to keep it. free_image is ignored if reg is false.
	region	[optional] Region to register the texture and material to.

		int	Flags = CS_TEXTURE_3D,
		iTextureManager *	tm = 0,
		csRef< iImage > *	image = 0
	)			[pure virtual]

Load an image as with LoadImage() and create a texture handle from it.

Parameters:

	Filename	VFS path to the image file to load.
	Flags	Accepts the flags described in ivideo/txtmgr.h. The texture manager determines the format, so choosing an alternate format doesn't make sense here. Instead you may choose an alternate texture manager.
	tm	Texture manager, used to determine the format the image is to be loaded in (defaults to CS_IMGFMT_TRUECOLOR if no texture manager is specified).
	image	Optionally returns a reference to the loaded image.

virtual void iLoader::SetAutoRegions

(

bool

autoRegions

)

[pure virtual]

Set whether to load each file into a separate region.

virtual csPtr<iLoaderStatus> iLoader::ThreadedLoadMapFile	(	const char *	filename,
		iRegion *	region = 0,
		bool	curRegOnly = true,
		bool	checkDupes = false
	)			[pure virtual]

Load a map file in a thread.

If 'region' is not 0 then portals will only connect to the sectors in that region, things will only use thing templates defined in that region and meshes will only use mesh factories defined in that region. If the region is not 0 and curRegOnly is true then objects (materials, factories, ...) will only be found in the given region.

If you use 'checkDupes' == true then materials, textures, and mesh factories will only be loaded if they don't already exist in the entire engine (ignoring regions). By default this is false because it is very legal for different world files to have different objects with the same name. Only use checkDupes == true if you know that your objects have unique names accross all world files.

This function returns immediatelly. You can check the iLoaderStatus instance that is returned to see if the map has finished loading or if there was an error.

Todo:

This is not implemented! Implement me or remove me!
