Particle-polygon collision callback about liquidfun HOT 1 OPEN

The C++ API has BeginContact() and EndContact() on the b2ContactListener
class.

http://google.github.io/liquidfun/API-Ref/html/classb2_contact_listener.html

On the Javascript version I don't think we have the bindings implemented in
https://github.com/google/liquidfun/tree/master/liquidfun/Box2D/lfjs/jsBindings/Dynamics/Contacts

You could try tackling this yourself if you're ready to hack in some C++.

If you find the listener system too tricky you could try hooking
up b2ParticleSystem::QueryShapeAABB

in
https://github.com/google/liquidfun/blob/master/liquidfun/Box2D/lfjs/jsBindings/Particle/b2ParticleSystemJsBindings.cpp

We're glad you like our library. Any chance you could share what you're
working on?

Thanks,
Stewart

Is there any way to set up a callback for contact begin/end between
particles and Box2D bodies?
I've searched the specification but found nothing – the listener is fired
only on collisions between Box2D bodies. I'm using the JavaScript version.
Thanks a lot, what an amazing library!
