Call a function in a node with an reference to it

Question

I have a Area2d, and I want to call a function in the script of the parent of the node, who enters the Area2d (body_entered).

How can I do that?

Answer 1

Use get_parent() https://docs.godotengine.org/en/stable/classes/class_node.html#class-node-method-get-parent

# Assuming you connected the `body_entered` signal to this function
func _on_body_entered(body):
    body.get_parent().the_function()
