In my 2D platformer game, I'm trying to create a button that, when the player or a box is on top of it, opens a door of the same color. Here is the code for the button:

extends StaticBody2D

onready var is_object_on_button = false

func _on_Green_Button_Area_body_entered(body):
    is_object_on_button = true
    print("button is down")

func _on_Green_Button_Area_body_exited(body):
    is_object_on_button = false
    print("button is up")

Code for the door:

extends StaticBody2D

onready var is_object_on_button = Green_Button.is_object_on_button
onready var door_collision = $CollisionPolygon2D

func _process(delta):
    if is_object_on_button:
        door_collision.set_disabled(true)
        print("unlocked")
    else:
        door_collision.set_disabled(false)
        print("locked")

The button prints the right things at the right time, so I assume the button is working properly, but the door constantly stays (and prints) locked. How do I fix this?

Edit: After a bit of experimentation, I think that the problem is that is_object_on_button keeps returning to whatever value its assigned at the start: If I set it to true at the onready, it stays true. I do not know how to fix this, either.
