Transpiling 2d physics engine from C to Go

• cxgo

  1 268 6.9 Go

  Tool for transpiling C to Go.

  

Today I remembered for some random reason that Go compiler was initially written in C and then was mostly transpiled into Go. So, I was curious, which projects exist to do something like this. And after some googling I've found very interesting project called cxgo.

• Physac

  3 381 4.4 C

  2D physics header-only library for videogames developed in C using raylib library.

To test this, I decided to try to convert something useful and found a small header-only 2D physics engine called physac.

• WorkOS

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• Ebiten

  53 9,805 9.8 Go

  Ebitengine - A dead simple 2D game engine for Go

Apparently, it was pretty easy! After some small fixes it started working. So, I added ebiten to see how it works in practice. And finally, I created a small wasm demo. It was harder, because of some strange bugs, which I could fix by getting rid of unsafe from transplited code. But it wasn't too much hard (actually - nothing, comparing to writing physics engine from scratch).

  Small demo of using physac 2d physics engine in golang
