**繼承：** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

說明
|
|
----
|
|
|
|
The **GDExtension** resource type represents a `shared library <https://en.wikipedia.org/wiki/Shared_library>`__ which can expand the functionality of the engine. The :ref:`GDExtensionManager<class_GDExtensionManager>` singleton is responsible for loading, reloading, and unloading **GDExtension** resources.
|
|
|
|
\ **Note:** GDExtension itself is not a scripting language and has no relation to :ref:`GDScript<class_GDScript>` resources.

|
|
|
|
:ref:`InitializationLevel<enum_GDExtension_InitializationLevel>` **INITIALIZATION_LEVEL_CORE** = ``0``
|
|
|
|
The library is initialized at the same time as the core features of the engine.
|
|
|
|
.. _class_GDExtension_constant_INITIALIZATION_LEVEL_SERVERS:

|
|
|
:ref:`InitializationLevel<enum_GDExtension_InitializationLevel>` **INITIALIZATION_LEVEL_SERVERS** = ``1``
|
|
|
|
The library is initialized at the same time as the engine's servers (such as :ref:`RenderingServer<class_RenderingServer>` or :ref:`PhysicsServer3D<class_PhysicsServer3D>`).
|
|
|
|
.. _class_GDExtension_constant_INITIALIZATION_LEVEL_SCENE:

|
|
|
|
:ref:`InitializationLevel<enum_GDExtension_InitializationLevel>` **INITIALIZATION_LEVEL_SCENE** = ``2``
|
|
|
|
The library is initialized at the same time as the engine's scene-related classes.

|
:ref:`InitializationLevel<enum_GDExtension_InitializationLevel>` **INITIALIZATION_LEVEL_EDITOR** = ``3``
|
|
|
|
The library is initialized at the same time as the engine's editor classes. Only happens when loading the GDExtension in the editor.
