[EditorImportPlugin]s provide a way to extend the editor's resource import functionality. Use them to import resources from custom files or to provide alternatives to the editor's existing importers.
EditorImportPlugins work by associating with specific file extensions and a resource type. See [method get_recognized_extensions] and [method get_resource_type]. They may optionally specify some import presets that affect the import process. EditorImportPlugins are responsible for creating the resources and saving them in the [code].import[/code] directory (see [member ProjectSettings.application/config/use_hidden_project_data_directory]).
Gets the options and default values for the preset at this index. Returns an Array of Dictionaries with the following keys: [code]name[/code], [code]default_value[/code], [code]property_hint[/code] (optional), [code]hint_string[/code] (optional), [code]usage[/code] (optional).
Gets the order of this importer to be run when importing resources. Importers with [i]lower[/i] import orders will be called first, and higher values will be called later. Use this to ensure the importer runs after the dependencies are already imported. The default import order is [code]0[/code] unless overridden by a specific importer. See [enum ResourceImporter.ImportOrder] for some predefined values.
This method can be overridden to hide specific import options if conditions are met. This is mainly useful for hiding options that depend on others if one of them is disabled. For example:
[codeblock]
func get_option_visibility(option, options):
# Only show the lossy quality setting if the compression mode is set to "Lossy".
if option == "compress/lossy_quality" and options.has("compress/mode"):
Gets the number of initial presets defined by the plugin. Use [method get_import_options] to get the default options for the preset and [method get_preset_name] to get the name of the preset.
Gets the extension used to save this resource in the [code].import[/code] directory (see [member ProjectSettings.application/config/use_hidden_project_data_directory]).
Imports [code]source_file[/code] into [code]save_path[/code] with the import [code]options[/code] specified. The [code]platform_variants[/code] and [code]gen_files[/code] arrays will be modified by this function.
This method must be overridden to do the actual importing work. See this class' description for an example of overriding this method.
