Member Function Documentation

virtual csLoadResult iLoader::Load ( iDocumentNode node,
iCollection collection = 0,
bool  searchCollectionOnly = true,
bool  checkDupes = false,
iStreamSource ssource = 0,
const char *  override_name = 0,
iMissingLoaderData missingdata = 0,
uint  keepFlags = KEEP_ALL 
) [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.
  • 'meshref' file: 'result' will be the mesh wrapper.
  • 'portals' file: 'result' will be the portal's mesh wrapper.
  • 'light' file: 'result' will be the light.

Returns csLoadResult.
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 if 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.

Parameters:
node is the node from which to read.
collection is 0 by default which means that all loaded objects are either added to the default collection or not added to any collection, depending on the value of the keepFlags argument.
searchCollectionOnly is true by default which means that it will only find materials/factories/... from current collection 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.
keepFlags Use these to define whether or not you wish to guarantee that all loaded resources are kept (default to KEEP_ALL). KEEP_USED is useful when you are loading from a shared library containing more resources than you actually need (a world file loading from a shared library of textures for example).
virtual csLoadResult iLoader::Load ( iDataBuffer buffer,
iCollection collection = 0,
bool  searchCollectionOnly = true,

const char *  override_name = 0,
iMissingLoaderData missingdata = 0,
uint  keepFlags = KEEP_ALL 
) [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.
  • 'meshref' file: 'result' will be the mesh wrapper.
  • 3ds/md2 models: 'result' will be the mesh factory wrapper.
  • 'portals' file: 'result' will be the portal's mesh wrapper.
  • 'light' file: 'result' will be the light.

Returns csLoadResult.
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 if 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.

Parameters:
buffer is a buffer for the model contents.
collection is 0 by default which means that all loaded objects are either added to the default collection or not added to any collection, depending on the value of the keepFlags argument.
searchCollectionOnly is true by default which means that it will only find materials/factories/... from current collection 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.

Load a map from the given 'world' node.

If 'clearEngine' is true then the current contents of the engine will be deleted before loading. 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.

Parameters:

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.
