[@elusiveelephant2563]

Hey Nico, Is there a way to update values in the database? For example, if a player gets a kill and I want to update their kills in the database from a 0 to a 1. This isn't possible with static variables in Unity I don't think. Is there a way to do this?

[@jinisunny7023]

How can I use delay in unity 2019.1.5 or less it is saying it is build in 2019.3 so can’t import and also says if you want to import some or every package will not be imported and will show errors if they are used So I continued and full error showed Please help sir

Thank you so much Nico! It helps me!

Olá amigo estou tentado fazer uma integração da unity com firebase para controlar um relé com o esp8266 mas não estou conseguindo fazer a alteração da string, se você puder mim ajudar ficarei muito agradecido. Seria mais ou menos assim: chave: led valor: "0" assim: led: "0" e quando eu clicasse novamente no botão mudaria de estado para led: "1"

[@aboodriazy3387]

by this method how can we retrieve user information like username, display picture? can anyone guide me on this?

[@thebeyondwithin]

Grazie for the tutorial Nico! I was wondering how can this be done for Android/IOS? Android/IOS credentials dont have a client_secret so the POST request in the ExchangeCodeForToken method does not work. Also how would you go about securing client_id, client_secret, API_key?

[@linekan2086]

Hey! thanks for tutorial! I have a question, in the minute 26:19, How i can extract only the localId from respones.Text? Thanks!

[@uNicoDev]

You check out the exact response from the docs: firebase.google.com/docs/reference/rest/auth#section-sign-in-with-oauth-credential You create an object that is serializable and that has the public field localId And then use the FullSerializer library to convert the JSON into that object: github.com/jacobdufault/fullserializer I think I showcased this in my Authentication video: kzbin.info/www/bejne/mqKbgXSNgaqiaac

[@serkantarakci1]

First, I appreciate for your work. But as a beginner (or maybe as a stupid) I don't understand why is it hard to find an easy tutorial in entire web. I want to learn a simple firebase signup and login in unity. What I expect that from a tutorial is, there are 2 input fields: email and password and there are 2 buttons: signup and login and simple short codes regarding them. But even in official firebase documents and videos there are too many codes, too many complicated stuff. Public,private, protected variables...blabla. For example, In here what is "Get google code"? I have never seen such a thing in apps or games. :( Make it simple bro.

[@uNicoDev]

Thank you for watching, I am sorry that this didn't fit your needs. This tutorial was specific for Google authentication, if you want an email password authentication tutorial you can check the playlist link in the description and go to my first video!
