I need somehow to know that all particles are in sleep state. Because I need to stop simulation then, save simulation mesh etc.
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?

The sleep threshold is expressed in Joules/Kg. So simply check if the kinetic energy of the particles is below the sleep threshold. Pseudocode:
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.
}

Thanks a lot for help. This is exactly what I am looking for.
Hello.
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
