Backend Services for Games - Auth Service #2

In the previous article I’ve built the authentication functionality. It outputs the previously mentioned Auth Token: a token that allows the client to call protected API in a safe way. But, as I said, a new problem arises: The user must be able to continue with their session without providing login credentials every few minutes. Refresh the token The easiest method to implement the refreshing of the auth token is… Using the current and valid auth token to request a new one. Continue reading

Let’s talk about the first service: the Auth Service. The project structure I can see you being so excited, but you need to wait a little bit more: I am starting a new project, so I first want to talk about how to organize it. I’ll code this service with C#, on ASP.NET 5. I create some C# projects: MHLab.Backend.Auth project: it contains the logic for the service itself. Continue reading

For this reason I decided to describe my process with some articles on this blog. Continue reading

Multiplayer RPG Series - Networking (TCP vs UDP)

And here we are with the first, real post about development of this project! I apologize for the huge delay. :) As most of you certainly noticed, we are planning to create a multiplayer game. This means that we need to communicate with other players around us: nobody likes a multiplayer game that has no multiplayer features! This directly brings us to our next need: we want a way to transfer data among players, to make them know about each other and about their actions. Continue reading

Multiplayer RPG Series - Concepting

So – as I said – to create this blog posts series I will develop a game step-by-step to help myself to understand what I need to write down. Before I start with code and tech, I want to do a little bit of concepting: just to have a straightforward target and to have well-formed ideas. Also, I will try to establish what I need to develop in order to complete this game. Continue reading
