hi ,

I'm creating this flocking system, where I'm using a wind POP to drive a group of particles about x and Z (a 2D plane) at random.

I'm using the Amplitude parameter in the Noise Tab (within the wind POP) for this… seems ok, at least for now.

I also have a few sequences of geos (all walk cycles) that run at different speeds.

Is there a way of getting the speed of particles within a certain range?

I need to group particles depending on their speed range to copy the correct walk cycle to that group. (e.g: slow particles will be assigned a slow walk, fast particles will have a fast walk… ).

Any ideas?

Thanks

I think I'm blind…

velocity of particles is displayed in the details pane (just in case someone has the same problem)

sorry… I'm newbie in POPs

Then you will want to get the magnitude of the velocity:

length($VX,$VY,$VZ)

You can just use $SPEED in POPs.
