Struct GltfLoader 

pub struct GltfLoader {
    pub resource_manager: ResourceManager,
    pub default_import_options: ModelImportOptions,
}

This object performs the loading of files in glTF format with extension “gltf” or “glb”.

Fields

resource_manager: ResourceManager

ResourceManager is needed so that textures and mesh data can be loaded from additional resources. The glTF format allows for other assets to be referenced by file path.

default_import_options: ModelImportOptions

Import options control where this loader should search for additional resources.

Trait Implementations

impl ResourceLoader for GltfLoader

fn extensions(&self) -> &[&str]

Returns a list of file extensions supported by the loader. Resource manager will use this list to pick the correct resource loader when the user requests a resource.

fn data_type_uuid(&self) -> Uuid

Must return a type uuid of the resource data type.

fn load(&self, path: PathBuf, io: Arc<dyn ResourceIo>) -> BoxedLoaderFuture

Loads or reloads a resource.

fn try_load_import_settings( &self, resource_path: PathBuf, io: Arc<dyn ResourceIo>, ) -> BoxedImportOptionsLoaderFuture

Tries to load import settings for a resource.

fn default_import_options(&self) -> Option<Box<dyn BaseImportOptions>>

Returns default import options for the resource.

fn is_native_extension(&self, ext: &str) -> bool

Returns true if the given extension corresponds to a resource in the native file format. The default implementation returns false, which assumes that the extension corresponds to a foreign file format.

fn supports_extension(&self, ext: &str) -> bool

Checks if the given extension is supported by this loader. Comparison is case-insensitive.

fn convert( &self, src_path: PathBuf, dest_path: PathBuf, platform: TargetPlatform, io: Arc<dyn ResourceIo>, ) -> Pin<Box<dyn Future<Output = Result<(), FileError>>>>

Loads a resource from the given path and converts it to a format, that is the most efficient fot the given platform. This method is usually used to convert resources for production builds; to make the resources as efficient as possible for the given platform. This method saves the converted resource to the given dest_path. If the resource is already in its final form, then this method should just copy the file from src_path to dest_path.
