Typedef Documentation

AssetImportSettings

typedef struct AssetImportSettings AssetImportSettings

AssetLibraryReference

typedef struct AssetLibraryReference AssetLibraryReference

Information to identify an asset library. May be either one of the predefined types (current 'Main', builtin library, project library), or a custom type as defined in the Preferences.

If the type is set to ASSET_LIBRARY_CUSTOM, custom_library_index must be set to identify the custom library. Otherwise it is not used.

AssetMetaData

AssetMetaData::AssetMetaData

The meta-data of an asset. By creating and giving this for a data-block (ID.asset_data), the data-block becomes an asset.

Note

This struct must be readable without having to read anything but blocks from the ID it is attached to! That way, asset information of a file can be read, without reading anything more than that from the file. So pointers to other IDs or ID data are strictly forbidden.

AssetTag

typedef struct AssetTag AssetTag

User defined tag. Currently only used by assets, could be used more often at some point. Maybe add a custom icon and color to these in future?

AssetWeakReference

AssetWeakReference::AssetWeakReference

Information to refer to an asset (may be stored in files) on a "best effort" basis. It should work well enough for many common cases, but can break. For example when the location of the asset changes, the available asset libraries in the Preferences change, an asset library is renamed, or when a file storing this is opened on a different system (with different Preferences).

It has two main components:

• A reference to the asset library: The eAssetLibraryType and if that is not enough to identify the library, a library name (typically given by the user, but may change).
• An identifier for the asset within the library: A relative path currently, which can break if the asset is moved. Could also be a unique key for a database for example.

Note

Needs freeing through the destructor, so either use a smart pointer or #MEM_delete() for explicit freeing.

Enumeration Type Documentation

eAssetImportMethod

enum eAssetImportMethod

Enumerator
ASSET_IMPORT_LINK	Regular data-block linking.
ASSET_IMPORT_APPEND	Regular data-block appending (basically linking + "Make Local").
ASSET_IMPORT_APPEND_REUSE	Append data-block with the BLO_LIBLINK_APPEND_LOCAL_ID_REUSE flag enabled. Some typically heavy data dependencies (e.g. the image data-blocks of a material, the mesh of an object) may be reused from an earlier append.
ASSET_IMPORT_PACK	Link data-block, but also pack it as read-only data.

eAssetLibrary_Flag

enum eAssetLibrary_Flag

Enumerator
ASSET_LIBRARY_RELATIVE_PATH

Definition at line 132 of file DNA_asset_types.h.

eAssetLibraryType

enum eAssetLibraryType

Enumerator
ASSET_LIBRARY_LOCAL	Display assets from the current session (current "Main").
ASSET_LIBRARY_ALL
ASSET_LIBRARY_ESSENTIALS	Display assets bundled with Blender by default.
ASSET_LIBRARY_CUSTOM	Display assets from custom asset libraries, as defined in the preferences (bUserAssetLibrary). The name will be taken from #FileSelectParams.asset_library_ref.idname then. In RNA, we add the index of the custom library to this to identify it by index. So keep this last!
