# haxebullet

|
|
|
||
|
|
[Bullet 3D Physics](http://bulletphysics.org/) bindings for Haxe.
|
||
|
|
|
||
|
|
Based on the webidl approach, works for HL/C & JS:
|

|
||
|
|
- https://github.com/HeapsIO/bullet
|
||
|
|
- https://github.com/bulletphysics/bullet3
|
||
|
|
- https://github.com/kripken/ammo.js
|

|
|
## Usage
|
||
|
|
|
||
|
|
[Reference](http://bulletphysics.org/mediawiki-1.5.8/index.php/Hello_World)
|
||
|
|
|
||
|
|
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.
