Killing Particles

[evanrudefx]

Hey,

Is it possible to kill particles using popkill in conjunction with pop proximity? I have particles following a curve using a popcurve force. I want particles that stray too far from the curve to die. 

Thanks

The popkill sets a the @dead attribute to 1, you can do the same in a popwrangle or directly delete the particles with the "removepoint" function.
in a popwrangle (make sure you set your input1 as your curve SOP)

// if the points are not within the search radius, delete them
if(pcnumfound(pcopen(0,"P",@P,chf("radius"),1))==0)removepoint(0,@ptnum);
