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 module. 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 GDExtension API. You can use them in C++ by using creating a godot-cpp based GDExtension, or with any of the community-created GDExtension implementations. Note though that some aspects of the code or directory structures may be different in GDExtension compared to the module APIs.
