Question

Hi, how I can call method Engine.has_singleton in C++, I’m trying to create GDExtension but there is no document for it, just GDExtension C++ example — Godot Engine (stable) documentation in English

Hey there,

By using
#include <godot_cpp/classes/engine.hpp>

you are able to call
Engine::has_singleton(...)

[dexterfstone]

gives an error

[zoeren]

That’s sad.

If you need help, you may provide some information about the error.

[dexterfstone]

a nonstatic member reference must be relative to a specific object

[dexterfstone]

I’d do it something like this:

#include <godot_cpp/classes/engine.hpp>
private:
    Engine *_engine;
	Object *_singleton;

    .cpp ...................
    if (_engine->has_singleton("test")) {
		_singleton = _engine->get_singleton("test");
		
	}
