Alright, so if I wanna do C++ with godot I have two ways:
Use GDExtension, this is more flexible but might cost some performance since you essentially call godot functions through a "middleman". Every godot function needs to be re-declared in GDExtension. Now, devs have put much effort into this, but there might be some functions that have not been re-declared.
Use modules, as I understand this is the most performant way BUT compiling time might be longer. Here you directly call the godot functions without a middleman.
My question is... How does Unreal Engine do this? It appears you can "add" the engine directly in Visual Studio and then run the game from there. Is this the godot equivalent to a module? Or is it something else? It feels like you can use UE as a library or SDK to make games. Would be nice if godot could do something similar.
