Making a large Battle Simulator game with Bevy and Rust

#gamedev #rustlang #bevy
Have you ever wondered how games like Ultimate Epic Battle Simulator are able to have millions of units on screen while running at a relatively fine FPS? Well in this video, I built on one of my previous videos "Remaking my game from scratch in an ECS with Rust and Bevy" where I attempted to create a battle simulator like UEBS. I wasn't very successful in the previous video but by the end of the video, using my newly learned skills in Bevy and Rust, I was able to develop a project that runs at a steady 100+ FPS when having 20k tanks duking it out on the big field. In this video I show you some useful optimizations when attempting to make a battle simulator game such as spatial partitioning through Quadtrees and rendering optimizations using custom render pipeline Shader Instancing with WebGPU and wgsl. I was no where near getting millions of units on screen but I'm pretty happy with this project as a whole! If you like the video make sure to drop a like and subscribe.
