How can I update the physics during the same frame?

Question

I'm trying to have a node change position, and then within the same frame be able to be detected by an Area2D that it has now moved into. My code in the test I ran looks as follows:

onready var a = $a
onready var b = $b

func test():
    a.position = b.position
    print (a.get_overlapping_areas())

func _physics_process(delta):
    if Input.is_action_just_pressed("ui_accept"):
        test()

The first time I hit enter, I get a blank array. Every time afterwards I get an array with a ref to b in it. Clearly the collision isn't being updated on the same frame as the motion.

I've tried using force_update_transform() in between the position change and the get_overlapping_areas() call, but that doesn't change anything. I'd appreciate any suggestions as to what I should try.

Comments

Have you tried passing it as an argument?

func _physics_process(delta):
    if Input.is_action_just_pressed("ui_accept"):
        a.position = b.position
        test(a.get_overlapping_areas())

func test(overlapping_areas):
    print(overlapping_areas)

It doesn't change the behavior, unfortunately.
