haxebullet
Bullet 3D Physics bindings for Haxe.
Based on the webidl approach, works for HL/C & JS:
- https://github.com/ncannasse/webidl
- https://github.com/HeapsIO/bullet
- https://github.com/bulletphysics/bullet3
- https://github.com/kripken/ammo.js
Usage
In order to get HL/C build to work you need to add haxebullet/bullet and haxebullet/hl directories into your build process so the compiler is able to find bullet sources.
In order to get JS build to work you need to add haxebullet/ammo/ammo.js script either by embedding or including it with a script tag.
