Today I'll show you the capabilities of Firebase by creating a Multiplayer game in Unity using services like Realtime Database, Authentication & Cloud functions! This setup will allow for secure matchmaking & turn-based multiplayer between users for all platforms and little to no cost!

Nico, I think that your explanations are thorough and great but I have a hard time focusing with the background music. I would prefer that there would be no background music at all because it's distracting to me.

Thanks for the video. From looking at your video I do not understand the waiting for move mechanism. Is the gamemanager polling the firebase server at an interval? Or does it make a request and then wait indefinitely for an answer?

Great video, one question. How would you add a timer, lets say user has 15 seconds to make a move?

@uNicoDev Жыл бұрын

Great question! So in the make a move cloud function you could have the function also store the move timestamp on the database... And then, before each move, check if that timestamp is older than 15 seconds... On the client side you could just have a local timer....maybe make the cloud function timer slightly longer so it's more forgiving to laggy players... If a player runs out of time the other player could send a request to another cloud function that could verify it's true and end the game (it's better that the other player or both do it so if the first one timeouts the game doesn't soft lock)

How do you handle players losing connection? I.e. in a 1vs1 multiplayer game where a lost connection from either player should result in game ending?

@uNicoDev Жыл бұрын

You could add a move timer and if it expires without that player making a move, then end the game (I wrote a comment below on how to do it with this set up). If you don't want to implement a timer in your game, you could have a hidden 'ping' that every player has to do every 15 secs or so that is set up in the same way Edit: here's the comment Great question!

Ciao Niko! If you want to experiment with something different than firebase that offers most of its features in a lightweight open-source solution, for my current Unity project I'm leveraging kinto-storage. I'm very happy so far, open to share more if interested

@uNicoDev Жыл бұрын

Hey! Currently in my production projects we are using Firebase and it would not be easy to migrate but it could be an interesting topic for a video to compare the two services, so I'd be interested to know more as I have not heard of this alternative before

why when i deploy the index file under every function in the cloud panel says us-central1 if i created the database in europe? thanks

@uNicoDev Жыл бұрын

Looks like you can change the region where your cloud function is located in the code itself by doing ".region('europe-west1')" when you invoke it, at example. Got it from here: firebase.google.com/docs/functions/locations#web

@kazimashiatsumaira1684 4 ай бұрын

I am confused. How did you signal other player from within the game that you want to join his room? There was no reference for the connection between them like a same id or room name being shared so one can join his friend's game and not a random player's

@uNicoDev 4 ай бұрын

So if you check out this video's code in the description, in the MatchmakingManager.cs, it is actually listening on a node when the userId is in the queue and the cloud function will 'match' players together by adding the gameId as a children of the node that the two players are listening to: github.com/rotolonico/Unity-Firebase-Multiplayer-Example/blob/v2/Assets/Scripts/Managers/MatchmakingManager.cs

The problem with your approach is firebase unity sdk on desktopis for development purposes only and shouldn't be used in builds as of today. => Firebase auth has no support for native desktop unity games
