cannon-es VS racing-game

// ============ // part 2 // add base vehicle body // reference: https://github.com/pmndrs/cannon-es/blob/master/examples/rigid_vehicle.html // ============ const carBody = new CANNON.Body({ mass: 20, position: new CANNON.Vec3(0, 6, 0), shape: new CANNON.Box(new CANNON.Vec3(4, 0.5, 2)), });

cannon.js hasn't been maintained for 7-8 years, the project lives on here https://github.com/pmndrs/cannon-es you import it like so

Cannon-ES - 3D physics engine

Since I'm a big Poimandres fan I looked into react-xr, and it was very easy to get a first WebXR project up and running. Unfortunately, there are many dependencies in the ecosystem which slowed me down: react-xr is built on top of react-three-fiber which is built on top of Three.js, and physics is enabled by use-cannon which is built on top of cannon-es. For a long time I was running into issues and helping fix them with a couple of pull requests, and ultimately it was preventing me from working on the actual project. Still, Poimandres is a great community and I got a lot of inspiration from the content being shared in the discord.

This was the post I was remembering, see repo here: https://github.com/pmndrs/cannon-es

btw canon has been abandoned for years. it continues to receive support on here: https://github.com/pmndrs/cannon-es which next to bug fixes also gives it types and esm/tree-shaking.

this is how i did it in racing game: https://github.com/pmndrs/racing-game/blob/main/src/effects/Dust.tsx both the dust and the skid marks are instances, this should be fairly fast.

The racing game works on desktop Firefox on Ubuntu. Kind of. I get only jumpy spinning random frames once the car starts. Maybe it's https://github.com/pmndrs/racing-game/issues/152

The space travel site works on desktop Firefox but I can only click and drag. I didn't find any way to zoom. Basically I'm stuck on the objects I can see: Earth, Moon and Mars. But I didn't even looked for help in the other comments. Got work to do now.

Thanks for answering :-)

beautiful! i love the looks and the physics feel great! you made your own engine for this? i've tried to make a mini racing game for fun once but physics (using cannon though) were the hardest part, it never felt as natural as this.

The open sourced racing game developed by Poimandres and other contributors on Github. The game features a 3D car in a track, and the user is supposed to reach the end of the track by driving the car to the end of the track as soon as possible. This project uses Cannon-ES, a physics library which is a fork of the original CannonJS by Stefan Hedman, currently being developed in house by the developers and other contributors of Poimandres.

https://github.com/pmndrs/zustand#transient-updates-for-often-occuring-state-changes you can do something like this in redux, too, but you can't select state in that case. i use zustand in games even, for instance https://github.com/pmndrs/racing-game the usual problems where react interferes with performance do no apply here.

there's a similar project that's open source and desperately looking for contributors: https://github.com/pmndrs/racing-game :-)
