Question

Hello guys,
I’m new in GDExtension, I define two classes helloWorld and cubeClass and defined in register_types like this:


Now I want add to configuration file in gdExtension file under bin path.
But I don’t know how to define another entry_symbol in this file.
Anybody know how to define that? Thanks :smiling_face_with_three_hearts:

I’m sorry for stupid question.
I found this plugin register_types source code and find my mistake.
Sorry again :pray:
