Engine extension APIs
=====================

This section introduces various ways in which you can extend the engine with C++ code.
You can use these APIs by creating a :ref:`module <doc_custom_modules_in_cpp>`.
Note that you can change the engine in many more ways than presented here — this section just presents
a subselection of common and useful ways to do it.

Alternatively, some of the functions presented here are also available through the
:ref:`GDExtension <doc_what_is_gdextension>` API.
You can use them in C++ by using creating a :ref:`godot-cpp <doc_about_godot_cpp>` based GDExtension,
or with any of the :ref:`community-created GDExtension implementations <doc_scripting_languages>`. Note though
that some aspects of the code or directory structures may be different in GDExtension compared to the module APIs.
