Help How can I add sounds for particles collisions?

[netstorm]

Hi dear friends!

Can you please help, how to add sounds when obi fluid particles colliding with each other and with other obstacles?



Thank you! 

I've read documentation about Collisions

Here is the text from docs: "To retrieve the particle-particle contact list, subscribe to its OnParticleCollision event."

So I tried to do this

And there is 0 contacts for particles. For colliders works fine.

To play sounds, when particles collide, I need information about collisions between them: colliding impulses, for example. How can I get this information another way, insted of particles collisions event, as it is not working?

Thanks!
