Inherits: ResourceImporter < Reference < Object

Registers a custom resource importer in the editor. Use the class to parse any file and import it as a new resource type.


EditorImportPlugins 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 get_recognized_extensions and 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 .import directory (see ProjectSettings.application/config/use_hidden_project_data_directory).

Below is an example EditorImportPlugin that imports a Mesh from a file with the extension ".special" or ".spec":

extends EditorImportPlugin

func get_importer_name():
    return "my.special.plugin"

func get_visible_name():
    return "Special Mesh"

func get_recognized_extensions():
    return ["special", "spec"]

func get_save_extension():
    return "mesh"

func get_resource_type():
    return "Mesh"

func get_preset_count():
    return 1

func get_preset_name(i):
    return "Default"

func get_import_options(i):
    return [{"name": "my_option", "default_value": false}]

func import(source_file, save_path, options, platform_variants, gen_files):
    var file = File.new()
    if file.open(source_file, File.READ) != OK:
        return FAILED

    var mesh = Mesh.new()
    # Fill the Mesh with data read in "file", left as an exercise to the reader

    var filename = save_path + "." + get_save_extension()
    return ResourceSaver.save(filename, mesh)

To use EditorImportPlugin, register it using the EditorPlugin.add_import_plugin method first.

Method Descriptions

Array get_import_options ( int preset ) virtual

Gets the options and default values for the preset at this index. Returns an Array of Dictionaries with the following keys: name, default_value, property_hint (optional), hint_string (optional), usage (optional).

int get_import_order ( ) virtual

Gets the order of this importer to be run when importing resources. Importers with lower 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 0 unless overridden by a specific importer. See ImportOrder for some predefined values.

String get_importer_name ( ) virtual

Gets the unique name of the importer.

bool get_option_visibility ( String option, Dictionary options ) virtual

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:

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"):
        return int(options["compress/mode"]) == COMPRESS_LOSSY

    return true

Return true to make all options always visible.

int get_preset_count ( ) virtual

Gets the number of initial presets defined by the plugin. Use get_import_options to get the default options for the preset and get_preset_name to get the name of the preset.

String get_preset_name ( int preset ) virtual

Gets the name of the options preset at this index.

float get_priority ( ) virtual

Gets the priority of this plugin for the recognized extension. Higher priority plugins will be preferred. The default priority is 1.0.

Array get_recognized_extensions ( ) virtual

Gets the list of file extensions to associate with this loader (case-insensitive). e.g. ["obj"].

String get_resource_type ( ) virtual

Gets the Godot resource type associated with this loader. e.g. "Mesh" or "Animation".

String get_save_extension ( ) virtual

Gets the extension used to save this resource in the .import directory (see ProjectSettings.application/config/use_hidden_project_data_directory).

String get_visible_name ( ) virtual

Gets the name to display in the import window. You should choose this name as a continuation to "Import as", e.g. "Import as Special Mesh".

int import ( String source_file, String save_path, Dictionary options, Array platform_variants, Array gen_files ) virtual

Imports source_file into save_path with the import options specified. The platform_variants and gen_files 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.
