I am a bit confused 
So Your navigation node has player as a child, but You want to delete its Player and use another one, but get variables from the first one ?
Generally both your players are instanced. There is one instance being child of navigation set in editor, and another instance, called from script based on packedscene. So they are two instances of one scene. They share every aspect of code, but their private variables will be different. Player nr1 is introduced in editor, You placed him somewhere in the viewport, so he has certain global_position. Player nr2 has been instanced in script and his position was never set, so it is default Vector2.ZERO. Player nr1 is a child of navigation, so his transform depends on navigation transform, Player nr 2 is orphaned, and is independent from any local position. The same goes for every export variable.
I guess You wanted to get actual path and position of Player. You should use reference for actual Player then, but why do you want him deleted ??
Hello, thanks for your answer, I’ll try to explain myself better

What I’m trying to do is instancing the player by code in the navigation2d scene but not by adding it manually in the scene tree. I instanced the player using this code in the navigation 2d script:
extends Navigation2D
onready var player = preload ("res://Player.tscn").instance()
func _unhandled_input(event):
if event is InputEventMouseButton:
if event.button_index == BUTTON_LEFT and event.pressed:
var path = get_simple_path(player.position, event.position,false)
$Line2D.points = path
player.path = path
And after instanced by code when i write the code i can get the player.position and the player.path variable assigend in the player script:
Player script:
extends KinematicBody2D
var speed = 50
var path : = PoolVector2Array()
func _process(delta):
# Calculate the movement distance for this frame
var distance_to_walk = speed * delta
# Move the player along the path until he has run out of movement or the path ends.
while distance_to_walk > 0 and path.size() > 0:
var distance_to_next_point = position.distance_to(path[0])
if distance_to_walk <= distance_to_next_point:
# The player does not have enough movement left to get to the next point.
position += position.direction_to(path[0]) * distance_to_walk
else:
# The player get to the next point
position = path[0]
path.remove(0)
# Update the distance to walk
distance_to_walk -= distance_to_next_point
But I don’t know why it doesn’t work well. So in order to work well I need to manually instanced the player in the navigation 2d scene and in the script just take the instanced player.
extends Navigation2D
onready var player = $Player
func _unhandled_input(event):
if event is InputEventMouseButton:
if event.button_index == BUTTON_LEFT and event.pressed:
var path = get_simple_path(player.position, event.position,false)
$Line2D.points = path
player.path = path
So my question is :what is the diference between manually instancing the player in the navigation scene and then in the navigation2d scene using this code to get the player variable and position:
onready var player = $Player
Than instancing the player by script and using this piece of code to get the player variable and position:
onready var player = preload ("res://Player.tscn").instance()
I don’t get why it works in one way and not in the other one.

Simple answer… because your player node is not a part of the sceneTree in the second example.
Do
add_child(player)
#>> then path get code here <<

Hello Wakatta, thanks for your answer
Mi idea is to open a new scene and instance the player and the navigation 2d separately:
Node 2d (main node)
navigation 2d (instanced)
Player (instanced)
So this is why I don’t want to add the player as a child of the navigation 2d scene, but I want to be able in the navigation 2d script to access the player’s script variables path and position. So I instanced the scene in the navigation 2d script.
But when I create a new scene and instanced both, it doesn’t work, and I don’t know why. Only work if the player is added as a child in the navigation2d scene and the instanced in the new scene.
Why is that?

The player node will work wherever you add it but it must be a part of the screenTree to get the variables you seek.
You can add the player node to another node by reference then get the path and position variables. It does not have to be added as a child of navigation2d
┖╴Main (Node2D)
┠╴Player (KinematicBody2D)
┖ Map (Navigation2D)
If the navigation node creates the player node then
onready var player = preload("res://Player.tscn").instance()
func _ready():
get_parent.add_child(player)
func _unhandled_input(event):
if event is InputEventMouseButton:
if event.button_index == BUTTON_LEFT and event.pressed:
var path = get_simple_path(player.position, event.position,false)
$Line2D.points = path
player.path = path

Thanks, I think is a bit more clear now
