In 2010 I tried to program a video game with a friend for the first time. And it was our first time with C++, too. Of course, it was C++2003 since C++11 was the new-not-yet-stable thing.

I must say that our approach was quite naive. For example, we thought we would always play the game on a LAN. Thus, we never worried about lag compensation.

Now, a few years have passed, and I have learned a thing or two, even though I still have to finish a game project.

So, at the beginning of this year, this friend pushed me to learn Rust, and I decided to learn it through game development again.

At a certain point, I decided to use a physics engine, and I found Rapier. I was especially interested in its determinism to finally implement a lag compensation mechanism. But I did not understand how to use it correctly. Only recently, I understood it favors an approach similar to functional programming, whereas I was trying an OOP-like approach. This also led to fights with the borrow checker. So, because of these problems and my usual decrease in interest and focus, I left yet another project incomplete. … [Leggi il resto]
