Shooting Downwards in a Platformer

I don’t know how to make the player shoot a bullet downwards, I can instance the bullet but I don’t know how to make the bullet rotate for move down. Shooting left and right works fine.

Player Script:

	if Input.is_action_just_pressed("Shoot") && can_shoot == true && !Input.is_action_pressed("ui_down"):
	var bullet = Bullet.instance()
	if sign($Position2D.position.x) == 1:
		bullet.set_bullet_direction(1)
	if sign($Position2D.position.x) == -1:
		bullet.set_bullet_direction(-1)
	get_parent().add_child(bullet)
	bullet.position = $Position2D.global_position
	current_bullets -= 1
	print (current_bullets)
if Input.is_action_just_pressed("Shoot") && can_shoot == true && on_ground == false && Input.is_action_pressed("ui_down"):
	var bullet = Bullet.instance()
	get_parent().add_child(bullet)
	velocity.y = Jump_Power
	current_bullets -= 1
	print (current_bullets)
if current_bullets == 0:
	can_shoot = false

Bullet Script:

extends Area2D

const Speed = 1000
var velocity = Vector2()
var direction = 1

func _ready():
    pass

func set_bullet_direction(dir):
	    direction = dir
    if dir == -1:
	    $Sprite.flip_h = true

func _physics_process(delta):
    velocity.x = Speed * delta * direction
    translate(velocity)


func _on_VisibilityNotifier2D_screen_exited():
    queue_free()


func _on_Bullet_body_entered(_body):
    queue_free()

Sorry if this is poorly formatted, its my first time using the Q&A. Any help would be greatly appreciated
