Issue description

C++ class WeakRef has no methods except get_ref() and seems no way to use it in c++. Its missing functions from the engine:

void set_obj(Object *p_object);
void set_ref(const Ref<RefCounted> &p_ref);

Steps to reproduce

n/a

Minimal reproduction project

Thanks!

I haven't tested this, but looking at the code, it appears that UtilityFunctions::weakref() can be used to make a WeakRef.

Does that work for you?

I've seen it before. but i think it wasn't working. I will test it again. Thank you.

UtilityFunctions::weakref() returns a Variant. And WeakRef class has no operator= so it cannot be assigned to a stored WeakRef variable. I feel like having operator= for this class is crucial.

Are you perhaps using a WeakRef variable instead of Ref<WeakRef>? I just tried the second and it works fine.

I didn't know about Ref<WeakRef>. Probably because I was expecting something like WeakRef<Object>. Thx. I'll try. I think this needs to be shown in the example project.
