❔ Creating a multiplayer Snake game WPF, Blazor, SignalR
Hello guys! I'm in a hole and can't seem to do anything right at the time and since i don't have much more time, i'm asking for some help with this. Please take a look at the code and i'll get you on my ideas.

So basically the game is running well for a single player.
It still need a decent menu
a Multiplayer Class
and finally a Server to handle the communication between the client. Prefferably launched on an actual WebServer not locally
it's too big a question to ask. i can summarize your possible approach to a few points.
1. set up a server that can correlate all the player's positions and actions
2. set up a communication system (SignalR or something, maybe even code your own)
3. change any method that makes updates to the players in the game to one that can receive input from the server.
so, you basically are trying to recruit ppl for your project?
I'm asking for a fresh set of eyes cause i can't seem to get what to do next
i have a major block in my head
since this is going to be multiplayer, you are going to rewrite the entire thing anyway
the game logic has to run on your server and not a client
the client just renders the data received from the server and sends its input to the server
also, you most likely have to figure out a way to enable clients/player to find a match - or even the server
so, now is probably a good time to take a break and a step back and figure out what things/workflows/user stories you need and how you are going to implement them
did you had a look on what i have so far ?
briefly
ok well it's my first so advanced project i didn't have anything to do with networking in code until i got this
so basically you think i should get models and control on the server?
yes, because the alternative would be to have that on each client
and how are you going to synchronize that?
is everyone going to wait for the slowest network connection?
what if a player disconnects?
well it is pretty simple game i think i would only need to pass the snake array
it doesnt matter what you need to pass
what if you got 5 players with 5 different arrays?
who is right?
i will only allow 2 so the network speed shouldn't be an issue but you're wright it only seems logical to have it on the server
the amount doesnt matter, its more than 1
ok starting small first step should be to get the server up and running and connect a single client
well, you should think about what to use for what
Blazor should to the trick right ?
blazor is web dev
you got a wpf app there
so not web dev
please excuse my ignorance i'm really new to this 🙂
not sure what your plan there is
what would you suggest ?
decide on one
not both
wpf definitely
if you want your server to use c#, then asp.net core will be your server framework
and then you get to decide how to communicate with that, http/rest requests and/or something real time communication like signalr or grpc
i would think SignalR should suffice
in any case, you are going to need error handling
if it's good for a chat programm should be enought for my purpose as well
and fault tollerance/retry logic
and as i mentioned before, you will have to figure out how your clients will find the server and find a game session
and if you ever want to actually release this project, how ppl are going to get a server. will you provide one? will they need to setup one?
will a player/client be a server
and so on
well i'm thinking my own server and the player is a client
the server will be hardcoded for the purpose of the project
then you need some hosting somewhere
but i can test it on virtual maschine on my own pc right ?
i mean sure, but you will encounter an entirely different case of problems, once the server is deployed
the kind you'll never get on a local machine
Makes sence
How about Docker?
thats a nice to have, doesnt change the fundamental problem
I‘ll google around for hosting when i get home
Do you have the time to kind of tutor me about it?
i dont tutor
if you got questions that google cant answer, you'll get plenty of help around here, if you show what you got troubles with
Will do 🙂
@RiA do you have some thoughts for me as well 🙂
i suppose you can set up a temporary system that delays all requests sent by (n + random) ms, to simulate network latency and jitter
same for the recieve side
damn the glitch in my head ist massive
i suppose i need to start from scratch
i'm taking the MVVM Pattern
Models: Snake, Grid, Food,Images, Sound
Views:Singleplayer, Multiplayer, MainMenu
ViewModels: GameState,Direction, Position
That would be the Main project
I'm not sure about the server. it should initialize the multiplayer. So one Listener always open. If a player starts a multiplayer another listener starts connects to the client creating a multiplayer and waits for another client connection. So the other client needs to be able to select the created game
once 2 players are connected the created game ist no longer visible for other clients and the two players are connected p2p
does it make sence that way?
Server: This is where your snake array actually lives. All actual game mechanics should be calculated here. In my opinion, the server should not know the client exists.
Client: This is where your players play the game. All the client does is sends data to the server and receives data from the server. In my opinion, the client should not know that the server exists.
API: This is the layer that connects the server and the client and is generally an abstraction over your server's chosen connectivity choice, whether it be a web API or real-time framework like GRPC. This is how you will ensure the client and the server don't exactly know about each other, but can be trusted to communicate in a standard way.
You do not need to think about an exact schematic for every specific function of how this will work just yet. I strongly recommend you have these three concepts in mind and just start programming!
and ignore MVVM for now, you can refactor later, once your code works
