I have a variable that keeps track of which direction my player is facing. I want this variable to be at a different default values depending of the current level being played.
For example,in Level 1 he faces left by default,but I might want him to face right in Level 2.

Here’s what I tried to do:

extends Node2D

func _ready():
    var facing_x = $KinematicBody2D.get("facing_x")
    facing_x = -1

This is the node of the game’s level,in case the information is relevant.

Hi, actually, get will only give you the value of that variable. Modifying it wont do anything to the original variable.

you should try something like

extends Node2D

func _ready():
    $KinematicBody2D.facing_x = -1

Your variable is defined in your player script that extends a KinematicBody2D, right?

I think you should access it by simply using dot notation.
eg:

onready var player = $Player_node
func _ready():
    var facing_x = player.facing_x  #copy value from node
    ...
    facing_x = -1 #change variable in function
    player.facing_x = -1 #change value in node

If you change facing_x by assigning a new value, it happens only locally (within the _ready function but does not apply to the actual Player node).

Anyway if you only need to change the sprite you could simply use flip_h().

Thank you very much,this solved the problem.

I have a variable that keeps track of what direction the player is facing not only to set animations,but also because I intend to add a dash feature to my game,and want it to happen in the direction the player is currently facing,so flip_h wouldn’t be enough.
