haxebullet
Native Bullet 3D Physics for Haxe. Includes library file for Kha.
Package is available on haxelib:
haxelib install haxebullet
Docs
Refer to original Bullet documentation.
Remarks
Based on Bullet 2.82, works on C++ and JS targets. Using original C++ sources of Bullet and Ammo.js for JavaScript respectively. The goal of this repository is to provide top class 3D physics solution for Haxe.
The bindings are not complete but it's very easy to add missing stuff based on what's already there. Feel free to contribute!
Usage
In order to get C++ build to work you need to add 'haxebullet/cpp/bullet' directory into your build process so compiler is able to find bullet sources.
In order to get JS build to work you need to add 'haxebullet/js/ammo/ammo.js' script either by embedding or including it with a script tag.
