Figure out what Actor was collided with

[tbookout]

Yes!

Not documented yet, but: given a contact, you can simply do this:

Code:

ObiSolver.ParticleInActor pa = solver.particleToActor[contact.particle];

The ParticleInActor struct contains the actor to which the particle belongs, as well as the index of that particle in the actor's arrays.

Awesome! 
My hack was a list of which actors I cared about, and particle range they contained..   Will gladly switch to using this method.
