Hi, beginner here. I want to apply key & door to this First Person demo (FPP interation)

Basically (as I understand) the Player has raycast to check if the door has method "interact" then press a button to activate the door open animation

Player script

	if Input.is_action_just_pressed("interact"):
		if $Yaw/Camera/InteractionRay.is_colliding():
			var x = $Yaw/Camera/InteractionRay.get_collider()
			print("COLLIDING")
			print(x.get_name())
			if x.has_method("interact"):
				x.interact(self)

Door script

func interact(relate):
	if !animating:
		if state == CLOSED:
			$AnimationPlayer.play("open")
		else:
			$AnimationPlayer.play_backwards("open")

What I try was add a key variable to the door and a Key object with script

func interact(relate):
	get_node("/root/Main/Street/Door/Door").key = true

then change the door script to

var key = false

func interact(relate):
    	if !animating:
    		if state == CLOSED && key == true:
    			$AnimationPlayer.play("open")

It's not working obviously and I have no idea how to do this correctly or is that a better way, Please help!
