Recently, I’ve been interested in various aspects of game development. One area of particular interest is how multiplayer games engines generally work (and deal with state). I came across an excellent series of articles on the architecture of client-server games by Gabriel Gambetta. Read these! At the end of the articles he presents a neat live demo to make concrete the ideas discussed.
I decided to make a clone of Gabriel’s demo so I could better understand how it worked. Once I got into it, I also added entity interpolation, which is talked about in the articles, but not implemented in the original demo.
