Invalid set index 'visible' (on base: 'null instance') with value of type 'bool'.

Question

Hello! I'm trying to make a button that makes a Spatial node and it's children invisible.

    onready var LL = $lightscar

func _process(delta):
    if Input.is_action_just_pressed("engine"):
        engineEnabled = !engineEnabled
        print(engineEnabled)
        if not engineEnabled:
            LL.visible = false

I keep getting Invalid set index 'visible' (on base: 'null instance') with value of type 'bool'. when I try to use it! How can I fix?

Hi.
The error means that LL is null and not an object. Therefore the problem arises from:

onready var LL = $lightscar

are you sure that $lightscar is correct?

Answer 1

if get_node_or_null(NodePath("lightscar")):
    $lightscar.visible = false

this checks whether the node exists but i cant see what the problem is

Answer 2

Hello mate, I just had the same problem. The variable becomes null for some reason, so i recreated the variable for ex:

onready var LL = $lightscar

func _process():
var ll = $lightscar
