I still have no clue how calling variables from other scripts work

I’ve been developing this rhythm game, (I know it’s quite ambitious for my second game on this engine) and I’ve come across a recurring problem: I can never seem to effectively call variables from other objects.
I’ve had this problem before with a group of position2d nodes trying to communicate with each other, but those were all children of a single node so I just used:
var pos = get_parent().get_node("Position2D")
However now, I am trying to call variables from a node in a different scene, and I keep getting an Invalid index: null instance error. Any advice would be appreciated, as i am very new to this engine.

code for the variable in question:
`func _on_Area2D_body_entered(body):
var piss = get_parent().get_node(“Player”)

if "Player" in body.name && piss.ATK == false:
	piss.HP -= 1 
	print_debug (piss.HP)

To access another node, you need a reference. It doesn’t matter where that node is in relation, as long as you have a reference you’re good.

Your area is detecting contact with a body. A reference to that body is passed to the function: body.

If you want to know if the body it contacted is the player

if body.name == "Player" && body.ATK == false:
    body.HP -= 1

You don’t need to get_node() the player, since you already have it!

thanks man! ill be sure to try that out!
