Unity User Data & Scoreboard Tutorial - Firebase Realtime Database

[@xzippyzachx]

*IMPORTANT!!!* These are some common issues and changes that are required since curtain parts of this tutorial are out of date. - The Unity package manager is no longer used to install the Firebase SDK. To install the Firebase packages start by removing any Firebase assets you may have in your project. Download the newest .unitypackage file from this link developers.google.com/unity/archive#firebase_realtime_database. Then in Unity go to Assets > Import Package > Custom Package. Now import the .unitypackage you downloaded. The Firebase core/auth/realtime-database packages will now be installed in your Unity project. - You may need to delete and re-download a new google-services.json file. Download it from your project settings in the Firebase console. Then put the new file in your Assets folder again. - There are also some code changes since this video was recorded. Make sure to check the GitHub repo for the most up-to-date code. If you still have issues feel free to open a help post on my Discord server: discord.gg/7rGAAqC

You're amazing for this. 2 years later and the script still works. Very rare for a firebase tutorial! Very clean and understandable. hot tip, if you're trying to get the child object that is deeper than a level show in this video, change this: string usernameResult = childSnapshot.Child("username").Value.ToString(); to this: string usernameResult = childSnapshot.Child("userInfo").Child("username").Value.ToString();

[@xzippyzachx]

Okay, I have tried everything to add the Firebase packages to my projects. The way you did it in the previous video, this video the and pinned comment in this video. The packages refuse to show up in my package manager and I get the following errors: Assembly 'Assets/ExternalDependencyManager/Editor/1.2.167/Google.IOSResolver.dll' will not be loaded due to errors: Unable to resolve reference 'UnityEditor.iOS.Extensions.Xcode'. Is the assembly missing or incompatible with the current platform? Reference validation can be disabled in the Plugin Inspector.

I tried switching platforms. I tried using the same version of Unity as you do and it still doesn't work. Any idea what I'm doing wrong here?

[@xzippyzachx]

Even if you aren't building for ios it seems to want the build module installed. If you install the ios build module for Unity those errors should no longer appear.

[@aadityarajkarki7610]

Hello very nice tutorial but I want to ask to access kill death we need userid right? so when I google login I will only get my own userid so I can only access my stat. I don't have another player ID so how do I access every player stats without id.

[@xzippyzachx]

I show in the tutorial how you can list out all the players data in a leaderboard. Is that not what you are looking for? If you want to get the stats/data of one player, yes you would need the specific UID of the other player. Not sure what type of game you are making but your systems would need to know the UID of the other player. If you have more questions I suggest asking on my Discord server.

It kind of depends on your use case, I would read the descriptions on the Firebase pages to get an idea of their differences.

[@caligis]

Really great tutorial! I got it working great. Now I want to adapt the tutorial to my own project which works across different scenes; do I need to initialize firebase and auth and things after this section?

[@xzippyzachx]

Glad it helped! Making Firebase work across multiple scenes would require the Firebase Manager to persist between scenes. One way you can do this is by using DontDestroyOnLoad.

[@caligis]

@@xzippyzachx I have another quick question. How common is it to have different UIs in the same scene? I feel like it's natural to have the profile page in another scene but keep getting stuck while trying to make it work across multiple scenes. Doesn't it get messy having all the "management" stuff in one single scene? I have this strange NullReferenceException in my text fields even though they are linked up in the inspector and declared in the code

[@xzippyzachx]

@@caligis Well when you switch scenes those text references will be lost since they are not in the second scene. Its common to have UI screens all in the same scene. You just need to make a UIManager that switches between the UI screens.

[@xzippyzachx]

You can set up your database any way you like. In theory you could make a multiplayer game with it but it wouldn't be the fastest. Maybe a turn based game or non fast pace game it would work for.

[@pierrot457]

Very nice tutorial ! Thanks a lot. I have one question, if you have a huge number of players (like one million for example), each call for updating the leaderboard would be very costly since you retrieve all the players from the database and you sort them. How can you optimize this ?

You could only get the highest X amount of users score. Read through the Firebase docs if you want to learn more about how you can do this.

How can you prevent the data being tempered from the user side and get uploaded to the server?

You would need to have a proper backend server that does the data calls to ensure its not tampered with. Using Firebase functions is another option if you want to go serverless.

Yes, you should look into saving lists of data in the firebase database. Here is the documentation firebase.google.com/docs/database/unity/save-data#append_to_a_list_of_data

Would you consider doing a tutorial on custom authentication, specifically steamworks SteamID > email/password? I feel like that's a huge thing for *any* game running on steam (there are many as you know)- to not have to disturb the flow with a email/password login when you already own it on steam..

[@xzippyzachx]

Yeah I would but I haven't used steamworks authentication myself yet. I don't specifically do research on topics I haven't used before in my own project just to make tutorials. But I do plan on using steam authentication in my own project some day. So yeah I may make a tutorial some day but that most likely wont help you since you are looking for a tutorial on it right now :|
