This project grew much larger in scope than I had originally intended, and burnout made it impossible for me to do more with it. It was already getting incredibly unwieldy, so I apologize in advance for not covering non-uniform splines, and the general jankiness of some parts. There are also quite a lot of places where I just talk about something without *showing* it, but since I couldn't animate it all, I opted to keep that information in rather than remove it altogether

MY FIRST EVER GAME! // Code Review

I'm adding mutliplayer networking to my voxel game.
I wanted to share this bug I ran into that took me a full day of detective work to solve. Reliable UDP was the root cause, because I didn't fully understand that the reason laminar recommends us to send a lot of reliable packets, is because, so packet acknowledgment are sent.

I'm using laminar networking library for rust.

Multiplayer programming bug BROKE MY GAME

In my quest to figure out how the game Fez, achieves their mind bending multi dimensional 2D/3D mechanic. II happily managed to make my own version of it, minecraft but played on a 2D slice in a 3D world like Fez.

This is actually a remake of an old video I made about this project. So don't worry if you had a dejavu haha, here's the old video: https://youtu.be/m5S0gLgg2rs 
The reason I remade it, was because I think the content of the original video is so incredibly good, and I want more people to know about it. Updated, improved much better pacing etc...

Making A Multidimensional Game

I considered not even posting a devlog on this because it’s kind of just a side project, but I thought…”hey, why not, there’s no reason NOT to post”, so here it is. Hope you enjoy it and please leave any feedback you have in the comments.
