If you're looking for a simple solution that doesn't require complex software, consider using polling. For example, imagine two players, A and B, are playing chess. You can have the client-side of both players request updates from the server at regular intervals. While this method may not be the most optimized, it will get the job done.
Here's an example:
function fetchUpdatesFromServer(){
setTimeout(function(){
$.ajax({
url: "/your_server_url?playerId=" + playerId,
method: "GET",
success: function(data){
//analyze data from server and take action
}
});
}, 500)
}
$(document).ready(function(){
setTimeout(function(){fetchUpdatesFromServer();}, 500);
});
If you're using C# MVC on the server side, you can leverage the SignalR library. Find more information here: https://www.asp.net/signalr. This library allows bidirectional communication between client and server, enabling server functions to call client-side JavaScript functions. SignalR is powerful and can handle tasks like managing user groups for specific interactions in your game.
I hope this information proves helpful!
