today, i'm learning to use realtime database in firebase, godot. but there's an error like this "Invalid call. Nonexistent function 'get_database_reference' in base 'Nil'.". Anyone know how to solve this please help me

You have to get the reference first. Sounds like you did not read the wiki. Please check the wiki for how to use the realtime database.

I just realized this page is written for 3.x. I'm not sure what version of Godot you're using. Let me know and if it's 4.x, I can update this page or make a new one accordingly: https://github.com/GodotNuts/GodotFirebase/wiki/Realtime-Database

i am sure that i did every setup step by step, i filled all requirements in env file, set database rule to true, i gave up. Today i try it again but it make me disappointed again.

I see. The error you're getting is because it's made outside of ready. Declare it and set it this way:

var db_ref
func _ready():
  db_ref = what you had before

[WolfgangSenff]

Conversely, I believe you can declare the variable as you have it as onready and that should work.
