ICE: number of particles in a state

[Chris Marshall]

Hello All,

Is it possible to easily obtain the number of particles in a particular State?

Thought it would be easy, but Friday fog is closing in!

Thanks,

Chris

Use the Get Set Size node like this :

OK I'm using the Get Neighbouring Particles by State, which has an output of Number of Particles. So with Enable Cutoff Distance unchecked, this should give what I want, but if I display the values, I'm getting different amounts displayed. Actually maybe it's not taking into account the self particle. 

Sorry, leave it with me.

as you were...

Thanks Guillaume,

My idea was right, but I suspect your solution processes somewhat quicker!!

Bah! Guillaume beat me to the punch. :p

Here's my alternate take on it:

Careful there! I may be talking blarney, but I think get set sum may give the total from the previous frame when used in a simulated tree. Not sure if that's been fixed though.

I wasn't aware of that bug but in my testing my tree evaluated fine.
Perhaps it was fixed already. (2011 SAP here.)

Could be. I'm on 2010 here (for my sins).
