I can't believe I am asking this but I am incredibly frustrated….. it should just be a simple expression in the group node $LIFE < .1 but it's not working……….. I want to group the particles that are just being born, any help would be greatly appreciated

nice! thank you! it never occurred to me to use the false statement as a way to trigger another conditional……. I like the inline as it feels easier to read…..
Thanks man you are the best!

right but I don't want a simple expression…… I have 5 if statements that I want to evaluate and return different values.
so something like this:
if ($F == 1, 1, 0)
will give me 1 if it's true and 0 if it's false
if i do this:
if($F == 1, 1, 0) || if($F == 5, 10, 0)
it will only return a 1 or a 0 not 1 or 10….. I want to do an inline function but I can't figure out the sytanx in hscript. I know how to create a python function to do this but not hscript

Technical Discussion » Birth Particle from group center?
- liquidsolid
- 12 posts
- Offline
This seems like such a simple thing yet i can't seem to figure it out. simply put i have an object that is broken into many different pieces. Using the conectivity and partition nodes i have since grouped these. Now i want to birth a particle from the center of each group, do some stuff in the pop net and then attach that animation back to each group. Any help would be greatly appreciated.

thanks alan! weird as it was that kinda had occurred to me…. well kinda. i have been having other issues with my install of linux and for some weird reason i feel like it may be my video card. from what i can gather Ati has crap support for linux and i think my issue is compounded by my low level ati card. i will look into the opengl stuff! thank you! and yes i found out real quick that having that pretty stuff turned on in a workstation environment is not a good idea….. pretty cool stuff though, maybe it will work one day.
