Calling super.to_string from custom _to_string method

Question

Using GDScript in Godot 4, I'd like to customize the string representation of a class using the default representation plus my own message. So, I'm just doing:

func _to_string():
    var my_string = super.to_string()
    my_string += " -> GREEN" if is_green else " -> RED"
    return my_string

However, this results in a stack overflow because of infinite recursion. Also tried using (self as Object).to_string() with the same result. Is there a way to do this?

Answer 1

Call super._to_string() instead, or just super().

Recurve

Answer 2

Unfortunately that gives a compilation error:

Cannot call the parent class' virtual function "_to_string()" because it hasn't been defined.

That's weird because it is defined in Object, which is the base class of everything.
