I need help in converting a single-player card game to multiplayer game

I'm making a version of the Egyptian Rat Screw. I've finished the single-player version where two players play on the same phone. Now I want to make it so they can play on two different phones over the internet.

I lost an entire day trying to figure out how am I supposed to do that. First of all, there are many Unity multiplayer solutions, and I don't know which to choose. I would go with the official ones like Netcode, Lobby, and Relay, but there are not many tutorials out there, and I'm completely new to networking.

Could someone take a look at the project and provide me some help, guidance, tutorials, samples, or anything really because I'm completely lost? Just tell me what to do now .

 

It's usually easier to start from multiplayer.
Converting single player to multiplayer is a bit of a myth, this can get quite difficult.

There are plenty of netcode libs, all of them should be able to handle card games

 

Yeah, that's not very helpful I've found a Blackjack UNet/Mirror sample on the forum, but it's kinda too complex for me. Ughhh, I just need to see a code for a very simple two-player turn-based (card) game. Or a simple tutorial that covers how to make a multiplayer game using XYZ library from start to finish. There aren't any.

 

I've lost a lot of time trying to make this work. I'm even considering giving some cash to someone that can do this for me. In that case, official Unity solutions like Netcode, Lobby, and Relay should be used (whichever is needed). And whoever does this must fork my project and build upon it. Also clean code, comments, etc.

If I'm doing it on my own, the library is not relevant, I just wanna make it work. I just need concrete guides.

 

There's some good videos explaining multiplayer concepts and a basic setup with Mirror here: https://www.youtube.com/c/ShrineApp/videos

Once you understand the basic principles take your pick on a solution, they should all work basically in the same way. Create some small projects implementing the fundamentals, you should be able to find videos on whichever solution you choose. Once you feel you have a sufficient level of understanding have a look at re-writing your project for multiplayer.

 

Multiplayer is hard, a day is not anywhere enough to learn how to make a working multiplayer game if you never done so before. Converting from single player to multiplayer usually means heavily rewriting all of your logic: however long it took you to get the single player working, expect it to take at least twice as long to get a basic multiplayer working.

 

I gave up.
