Generating and moving particles on each primitive

[yavahue]

I have a 1 object that consists of a ~1000 closed curves/splines (same ammount of primitives),

i want to generate particles on each curve and move those particles along them, but each particle stays on that same curve it has been generated onto.

 

i started with popnet with a force and a pop wrangle @P = minpos(1,@P);

but of course the particles are jumping on the next spline when it comes near it, which i want to avoid. 

Also tried adding the popnet inside a for each prim loop, but not sure how to use metadata from that loop inside a popnet (particles disappear after the 1st frame)

Can any1 please guide me on what logic i should be using?

You may want to try using a carve node followed by a blast/delete to keep only point #0. This will allow you to move a point along each line, without dealing with popforces.

Atom, thanks for reply. I tried your setup - it works good.

Although i want a lot of points moving by each spline, not just one, with random speeds and directions.

Grab MOPS and follow this - https://entagma.com/houdini-in-five-minutes-18-sops-redshift-mops-isocontours-setting-up-the-particles/

YES!) i just upgraded to MOPs 1.5 - and you came up with this entagma tut!

Thanks a lot! its just what i need!
