After a node has been instanced as a child of another, is there a way to set it to that it disregards its parent’s coordinates?
I’m creating a projectile shooter whose projectiles move with my character. It is quite weird.

The correct solution is don’t make the projectile a child of the character. Add it to the scene node or a container. The simplest way to do this is to use get_parent().add_child(projectile), although that comes with some drawbacks, as you have to make sure your character has a parent node.
Alternatively, you can add a Node to your character and add the projectiles to that. Node doesn’t have position information, and so it won’t pass any position to its children.
When I try tried this, the projectiles seem to spawn off screen (despite the fact I set their position beforehand)
Do I need to set their positions some other way?

Add projectile nodes to the parent node that doesn’t move, not character.
You can also set projectile nodes as top level, this will disregard parent’s transform:
func _ready():
set_as_toplevel(true)
Also, you can add a dummy Node to your character and spawn your projectiles there:
var dummy = Node.new()
character.add_child(dummy) # can be setup via scene ofcourse
dummy.add_child(projectile)
The dummy node doesn’t inherit from Node2D so it will not pass down parent’s transform to its children!
When I tried this, the projectiles seem to spawn off screen (despite the fact I set their position beforehand)
extends Area2D
var cooldownReady = true
var alternatingFire = 'left'
onready var projectile = preload("res://scenes/Player/Fire/allyProjectile.tscn")
func _ready():
pass
func _process(delta):
if Input.is_action_pressed("ui_select") and cooldownReady == true:
fireGun(alternatingFire)
elif Input.is_action_pressed("ui_select"):
# oncooldown
pass
func fireGun(direction):
cooldownReady = false
$CooldownTimer.start()
var firedProjectile = projectile.instance()
if direction == 'left':
firedProjectile.position = $LeftGun.position
alternatingFire = 'right'`enter code here`
elif direction == 'right':
firedProjectile.position = $RightGun.position
alternatingFire = 'left'
$projectileRef.add_child(firedProjectile)
func _on_CooldownTimer_timeout():
cooldownReady = true
Do I need to set their positions some other way?
(The alternating fire is for the character’s 2 pistols, every odd function call fires first pistol and the other’s fire second. projectileRef is the node I added to the player)

Try firedProjectile.global_position = $LeftGun.global_position
position works locally relative to a node, so when you’re trying to set projectile’s position relatively to character’s one, it will spawn projectile at Vector2(0,0), which in global coordinates means “off the screen”.

This works perfectly. Thank you!
