Thinking Particles confusion
Are there any TP tutorials around?
I’ve worked my way through the 3Dcafe one and the Maxon tutorials but I’m still very confused.
Specifically with Ppass I’m unsure when you’re working with the particle group as a whole, or with individual particles. If someone could explain this works I’d be very grateful. I find the manual a bit confusing.
I’m trying to use PDie to kill off the particles when they collide with, or are inside, geometry and it’s just not working for me. I manage to kill off one of the particles but not all.
thank you

Sorry, message got lost.
What I was trying to say was thanks Adam, I’ll give it a go.

PPass is basicaly an iterator that goes through all particles of a group on each execution of the Expression. If you check particles on collision you can imemdiately use the bool output of the PCollision node to enable/disable PDie, or alternatively set the age of a particle to it’s lifetime.

Thanks Bjorn,
I got the impression from the manual that that was the case. Does that mean that it evaluates from n=1 to particle_count every frame?
I’ve set up a Pstorm which generates 35 particles which go on and do their thing and I’m trying to Pdie each one when it’s y coordinate is greater that a given value. I’ve used Ppass and Pgetdata with the required connections and comparison but only the last particle actually dies. Connections from Ppass are ‘particle’ to the Pdie node, and Pgetdata.
Thanks Alan

Maybe post your setup so i can see what happened.

thanks to Arndt,
It was the time setting in the PDie node – needed to be set to zero!
