I want to implement a version of steam-user in java, which is definetly not easy for me. The problem is I dont really know what I have to do to logon to Steam Servers, if I have to make a loop or so that checks if I am connected or something else. So my first goal is to do something like a logon mechanism. I also know how to use protobufs but I dont know which I have to use. Hopefully there is someone out there who can help me out!
