For now I use just a timer, but I want to use some smart way to check simulation done. So basically I need to know a percent of perticles are in sleep state and if like 99% in sleep state then considering simulation done.

It there a way to do what I wan currently?

Code:

Oni.GetParticleVelocities(solver,velocities,numParticles,startingParticle);
for (int i = 0; i < velocities.Length;++i)
{
    if (velocities[i].sqrMagnitude * 0.5f <= solver.parameters.sleepThreshold)
     // this one is sleeping.
}

See the last bit of: http://obi.virtualmethodstudio.com/tutorials/scriptingparticles.html for more info on how to use low level particle getter/setters.

After updating to the new Obi version 4.0.2 and there is no more GetParticleVelocities method. 
So I am not able to check the simulation done condition. 
How can I do it now in a new version? Thanks
