Question

I was trying to get a node to constantly teleport next to another node. This runs without errors but has no effect:

extends "res://character_body_2d.gd"

@onready var abstract_mob: CharacterBody2D = $".."

func process(_delta: float) -> void:
	global_position.y = abstract_mob.global_position.y
	global_position.x = abstract_mob.global_position.x - 16

You’re missing an underscore before process. It should be _process
