Can I access an Object with array brackets, like foo[12] in Godot?

C++ allows me to override the brackets operator, and Godot also allows me to make an Object iterable. I'm interested in my Object, which fetches results, to allows direct access to an index via the brackets. Is that possible?

Kinda. When you use brackets on an object. it'll just act like a getter.

For example

var something := "Test"

func _ready() -> void:
    print(self["something"])

This will print test.

Thanks for your time, yeah but that would not allow me to do self[0] 🤔

Unfortunately there is no way to do that yet (accessing as-is by index). You can technically make a workaround by getting the property list on said object and then check what index it is. But at the end of the day you still technically would still be using a String

Yeah, meh! Thanks though ❤️

This is the closest thing i can think of. Both would print the same thing

var something := "Test"

func _ready() -> void:
        # zero would be pointing to the script
    print(self["1"])
    print(self.get("1"))

func _get(property: StringName) -> Variant:
    if not property.is_valid_int():
        return null
    var properties = get_script().get_script_property_list()
    var script_property = properties.get(int(property))
    var result = get(script_property.name)
    return result

Again this is still actually using a String but its the closest thing to what you wanted.

this would return something right?
I'm looking for a shorthand so Foo[0] returns Foo.results[0]
But I could also use a String for that. I thought of that approach but then I'd prefer a .get_index(i: int) method

[chrome dirge]

Yep it would return something. If you want to make a custom function then its even easier as you can constraint the type to only accept int. But yeah no Foo[0] as-is. Either a workaround or make a function that returns the variable from the property list.
