i want to spawn these things at a set distance from the player, in a random point of the upper circumference formed by the distance radius, but after spawning they just travel in random (relative to where they spawned relative to the player) directions

this shouldn't need sharing since it works for other travelling attacks but whatever

#_process of the attack node
func _process(delta: float) -> void:
	if Time.get_ticks_msec() > endtime:
		queue_free()
	global_position = prior_global_position+travel.call(self)*delta
	prior_global_position = global_position
	return

#the travel and spawner functions:
func page_flurry_travel(node,travel_angle):
	return Vector2.LEFT.rotated(travel_angle)*200
func page_flurry_exec(delta) -> void:
	flurry_duration -= delta
	if flurry_duration <= 0:
		flurry_duration = 0
		flurry = false
		attacks_onscreen -= 1
		return
	if Time.get_ticks_msec() < flurry_lastspawn+333:
		return
	flurry_lastspawn = Time.get_ticks_msec()
	var pinpoint = RandomNumberGenerator.new().randi_range(0,PI) #top half circle
	var player = get_tree().current_scene.get_node("Player")
	#FIXME vector magnitudes
	var startpos = player.global_position + Vector2.RIGHT.rotated(pinpoint)*200
	get_node("Hitbox").attack(1,false,startpos,2,func(x): return page_flurry_travel(x,pinpoint),droppable_init)
	return
