Note that this is not the only place. You can also access a static method via an instance.

But according to the issue this already works. I find it a little weird that in this implementation, is_custom()
and is_standard()
will return different values for static_func
and Test.static_func
.

It is worth adding a comment that this wrapper was added only as a workaround to the issue described in #79521 (comment).

Instead of StringName
, you can use a GDScriptFunction
pointer here.
StringName method; | |
GDScriptFunction *function = nullptr; |
Although your approach with StringName
is safer.

Also needs script.is_valid()
check and hot reloading implementation, see #81628. Your approach with StringName
is safer.
