Question

Hey, i am new to Godot and im trying to create a clicker game
I’m getting “invalid get index on base nil” error in this script:

@onready var main = %MainButton

var score = main.score

and click.gd script that attached to the MainButton object contains this:

var score = 0

how can i fix that error?

@AGJ

%MainButton

you already set the MainButton unique name?

[AGJ]

yeah mine MainButton have unique name tag on it

[zdrmlpzdrmlp]

at where do you put this line

@AGJ

var score = main.score

not in _ready()?

[AGJ]

no, that line is not in _ready()

extends Button

@onready var main = %MainButton`

var score = main.score

[zdrmlpzdrmlp]

try change it to:

@AGJ

var score = main.score

@onready var score = main.score
