Clone access only variables

Godot Version

Question

Im trying to make a variable that tells a clone what if statements it can and can’t access.
So what I’m trying to figure out is how can define a varible for the original and the clones that is independent from the other variables.
I currently have something that looks like this:

var selfType == 0

if Input.is_action_pressed("key1"):
	duplicate()
	var justCreated = true
	if justCreated:
		var selfType = type
		print_debug("Cloned")
		justCreated = false

My current attempt is defining the variable twice.
