Game development, rust and open source.
I'm currently working on Cargo Space, a 2D coop space game made using the Bevy game engine.
I post about its development and the various tools I make, use or improve along the way.

Most of the Bevy crates I maintain have now been updated for 0.16. I ended up making a graph to track what needed to be done first, including dependencies I was waiting for
- bevy_matchbox: direct p2p, including web
- bevy_ggrs: p2p rollback
- bevy_pancam: map-like cameras
- bevy_trauma_shake: camera shake
- noisy_bevy: cpu/gpu noise
- bevy_pkv: persistent key value store
- bevy_web_asset: http assets
- bevy_roll_safe
- bevy_sparse_grid_2d
- bevy_crossbeam_event
I just finished porting my extreme bevy tutorial series to Bevy 0.14 (how to make a p2p multiplayer web game).

That finally concludes this version's porting work for me, the following crates are now bevy 0.14 compatible:
bevy_matchbox
bevy_pancam
bevy_roll_safe
bevy_smud
bevy_pkv
bevy_web_asset
bevy_trauma_shake
bevy_lospec
bevy_crossbeam_event
bevy_sparse_grid_2d
noisy_bevy
Let me know if I missed a crate you care about.
In my previous post, Introducing Matchbox, I explained how Matchbox solves the problem of setting up peer-to-peer connections in rust web assembly for implementing low-latency multiplayer web games. I said I'd start making games using it and I figured it's about time I make good on that promise, as well as write a tutorial while at it. I'll explain step-by-step how to use Bevy, GGRS, and Matchbox to recreate the old classic Extreme Violence by Simon Green with online p2p multiplayer using rollback netcode.
I just updated Extreme Bevy, my tutorial series on how to create a low-latency p2p web (and native) game using matchbox and bevy_ggrs to Bevy 0.13.
And I also finished chapter 5, on procedural generation. It's starting to look like an actual game now :)
I just released matchbox and bevy_matchbox 0.9.
It's a solution for painless peer-to-peer WebRTC networking for rust wasm (and native).
New in this release is Bevy 0.13 support.
#Bevy 0.13 is out now!
It features Lightmaps, Irradiance Volumes, Approximate Indirect Specular Occlusion, Reflection Probes, Primitive Shapes, ECS System Stepping, Dynamic Queries, Inferred Command Flushes, 2D Nine-Patch, Camera-Driven UI, and more!
@erin_catto really interesting watch, and great reference for comparing solvers. I'm a bit surprised xpbd did so poorly. I've been dabbling a bit with it, and i was also struggling a lot with friction...
I'm also wondering how the performance with the different solvers are? If one is cheaper maybe you could afford to do additional substeps or iterations?
I am following this fantastic #XPBD tutorial in #Bevy by @johanhelsing and I highly recommend it after learning some of the basics of Bevy 😍
https://johanhelsing.studio/posts/bevy-xpbd/
The tutorial isn't complete yet, but the first 6 parts are already a lot of material!
The attached GIF is the result of the first part ✨
@johanhelsing thank you for this treasure 🥰
PS: I know there is the physics library bevy_xpbd, but I want to implement XPBD from scratch for learning :D
In a sudden and ambitious outburst of not-invented-here syndrome combined with hype-train, I decided there weren't enough physics engines out there and it would be a good idea to write one myself using all the latest buzzwords. In this tutorial series, I'll explain step-by-step how to build an extended position-based dynamics (XPBD) rigid-body physics engine using entity component system (ECS) architecture in rust.
