Var from signal won't update

Help Programming

Hello, I have 2 classes (Player, Projectile) and I want to change the spawning position of the Projectile depending on the facing direction of Player. I put a signal in Player for that :

Player.gd

extends CharacterBody2D

signal is_facing_right

func handle_flip():
	is_facing_right.emit(false) # or true

I then catch the signal in Projectile

Projectile.gd

extends CharacterBody2D
class_name Projectile

var starting_orientation : bool

func _ready():
	parent.connect("is_facing_right", _on_facing_right)
	set_starting_position()

func set_starting_position():
	print("set_starting_position() : " + str(starting_orientation))
	if !starting_orientation:
		position = parent.position + Vector2(-starting_offset, 0)
	elif starting_orientation:
		position = parent.position + Vector2(starting_offset, 0)

func _on_facing_right(value: bool):
	print("_on_facing_right() : " + str(starting_orientation))
	starting_orientation = value

But when I call it, starting_orientation doesn’t change

Can you show the code where handle_flip is called?

Also it does change? It says false after setting it when set_starting_position is called

It won’t change before you set it

This is before you set it in

Player.gd (just the useful part)

func _physics_process(delta):
	var direction = Input.get_axis("ui_left", "ui_right")
	if direction:
		velocity.x = direction * SPEED
		handle_flip()

func handle_flip():
	if Input.get_axis("ui_left", "ui_right") < 0 && !find_child("Sprite2D").flip_h:
		find_child("Sprite2D").flip_h = true
		scale.x = -scale.x
		is_facing_right.emit(false)
	elif Input.get_axis("ui_left", "ui_right") > 0 && find_child("Sprite2D").flip_h:
		find_child("Sprite2D").flip_h = false
		scale.x = -scale.x
		is_facing_right.emit(true)

The signal works fine, it’s just Projectile that I can’t understand for now

I don’t see any issue in projectile, it works as expected from the output, when do you want the variable to change instead?

@athousandships
When I need to change the position of Projectile in set_starting_position()

But maybe I need to change the position before instantiate it so I think you were right !

EDIT : I just needed to edit the parent class before it instantiated, before the position were calculated after the instanciate()
