Write the code here.

┬┐Are you accesing every frame to this variable?, if you want variable value every frame should do that,i think accesing basic types is by "value" not reference.

sorry i didn't understand what you just said.here is the code though:

script 1:

var player_direction = 0

func _ready():
    set_fixed_process(true)

func _fixed_process(delta):
    if Input.is_action_pressed("MoveRight"):
        player_direction = 1
        print("player_direction_script1 =", player_direction)

    elif Input.is_action_pressed("MoveLeft"):
        player_direction = -1
        print("player_direction_script1 =", player_direction)

script 2:

var player_node
var player_direction

func _ready():
    player_node = get_node("/root/level/player")
    player_direction = player_node.player_direction
    set_fixed_process(true)

func _fixed_process(delta):  
    if Input.is_action_pressed("DEBUG_INFO"):
        print("player_direction_script2 =", player_direction)

what's happening is that it's printing "player_direction_script2 = 0" nomatter what value its set to in the first script.

Your error:
You copy playernode.playerdirection a single time at startup to the local value player_direction.

This can work with objects like "player_node" because you'd actually copy a reference (kind of a pointer) but won't work (be updated) with simple types like numbers. They're just copied by value.

Output "playernode.playerdirection" in the fixedprocess in script2. Not the local variable "player_direction".

func _fixed_process(delta):  
    if Input.is_action_pressed("DEBUG_INFO"):
        print("player_direction_script2 =", player_node.player_direction)

Im not in a computer but i think that the playerdirection var declaration of script 2 should be in the fixed process of script 2 because ready function only executes 1 time at start. Other thing you can do is "omitt" this declaration and access directly to the playernode.player_direction. Object var's stores entire object reference. But your player direction var only stores a copied value.

Edit: i did't see previous response. It's the same with other words.

I finally got it to work, thanks :)
