How do I deal with UID ?

I have a rocket that creates a pinned particle effect.

As soon there are more rockets and one get's destroied...all particles of all rockets disapear.

I need only the destroyed rocket's particle destry too. Not all of them. UID is very very abstract for me and quite hard to understand how to deal with...I watched several posts and the help...but did not be able to solve my problem. Can you show me a sample to my problem ? thanks so much guys...

My guess is using container would be the best solution for this..

Using uid is ofcourse also possible.

It would mean that while pinning the particles you could set an instance variable on the rocket to particle.uid

and on rocket destroyed - pick particles by unique ID = rocket.variable

thanks a lot
