I Spent 1 Week Learning to Code Shaders with Bevy & Rust

#gamedev #bevy #rustlang In this video, I used an entire week of my spare time trying to learn the secrets of shader effects using the programming language rust inside of the bevy game engine. My journey started because throughout my game development journey, my games all seemed a bit visually bland and the only way to fix this was to learn how to utilize GPU shader languages such as glsl and wgsl to create post processing effects such as bloom, vignette, and film grain as well as spicing up environments with water shaders and effects such as an energy ball. I started out by creating shaders inside of a website called Shadertoy, which allowed me to experiment in realtime with shaders so that I would be ready to port them to wgsl and use them readily inside of bevy. Throughout this video I was able to create a total of 3 shaders in this 1 week time frame. Specifically, I made a water shader, an electric energy ball shader as well as a film grain post processing effect using special techniques such as hashing to simulate a random function inside of shaders which do not retain data between frames and noise generation to make the effects seem more detailed. Also just an FYI, I did not do all this in a 1 week time frame but I create this whole project, including the editing within a 1 week amount of time. I did this so I could have time to rest in between working on this project as I did not want to feel too burnt out.
