if follow.unit_offset > 1:

going through this code i faced with the issue that enemies were still shooting for ever even when they were off screen, this fixed the issue for me:

func _process(delta):
	follow.offset += speed * delta
	position = follow.global_position
	if follow.unit_offset == 1:    # changed  follow.unit_offset > 1 to follow.unit_offset == 1
		queue_free()
