Unity User Data & Scoreboard Tutorial - Firebase Realtime Database

Hello, its working in 2023??? Thanks

legit full lag

thanks for the video. You help me a lot !!! success in your work♥

Can i load data from google sheets?

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

every time I call the save data method, unity crashes... help :(
Also, there is no "My Registry" on my unity, I am using 2021.3.16f1

I tried redownloading google-services json, still same, crashes when calling the save data method

I need help please. When I'm trying to reference my FirebaseDatabase, I get this error message: DatabaseException: Failed to get FirebaseDatabase instance: Specify DatabaseURL within FirebaseApp or from your GetInstance() call. What ist the problem here? I downloaded the json file and put it into unity.

please help me how do I delete data from firebase using button or something script in unity?

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();

hey i am getting a bunch of errors and i simply cannot fix them

life saver!!!!!!!!!!!!!!!

i got data base reference null error even i download full project

/* Hi there. Another great tutorial. I failed a bit until I checked the comments.
*Fortunately I muddled my way through, one small caveat to smooth UI swapping.
* I commented out all of the methods for swapping screens. UserDataScreen() .. RegisterScreen() etc.
I replaced all of these methods with */

public void SwitchScenes(GameObject nextUI)
{
if (instance.activeUI.activeInHierarchy)
{
instance.activeUI.SetActive(false);
}

instance.activeUI = nextUI;
instance.activeUI.SetActive(true);
}

// added a variable at the top:

public GameObject activeUI;

// in Awake() I added this:

if (!instance.loginUI.activeInHierarchy)
{
instance.loginUI.SetActive(true);
instance.activeUI = instance.loginUI;
}

//And the magic of all of this is, when I want to switch to a new scene, it doesn't matter which UI I'm travelling from, it will remember, deactivate the "activeUI" and activate the UI passed in the method.

UIManager.instance.SwitchScenes(UIManager.instance.userDataUI);

// For anyone who sees this comment I hope it makes a difference for you, and HAPPY NEW YEAR <3

Thank you for going into detail about the db rules, I had mine just slightly wrong and was helpful to see your example.

".read": "auth != null",
"$user_id": {
".write": "$user_id === auth.uid",
}
}

Well cant you just use unity instead of firebase at all

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?

can i make multiplayer game in unity with firebase with out using firebase cloud functions will i have to use listners or what please someone guide me

Thanks!

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..

Great tutorial :) thank you

Great job, thanks for sharing!!

Can firebase be used for desktop games?

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 ?

thank you man , just bless you!

I have this error, any help, please ? (great video!!)

Assets\Scripts\FirebaseManager.cs(400,48): error CS0246: The type or namespace name 'scoreElement' could not be found (are you missing a using directive or an assembly reference?)
