Rotating particles randomly on one axis (script ?)

[stevesideas]

Hi guys,

I have a bunch of instanced shaped particles heading in one direction but they are all oriented up the same way. I tried this script:

on ChannelsUsed pCont do
(
pCont.useOrientation = true
)
on Init pCont do
(
--insert variables here
)
on Proceed pCont do
(
  count = pCont.NumParticles() 
  
  for i in 1 to count do 
  (
    pCont.particleIndex = i 
   pCont.setParticleOrientation i = [90, 90, 37]
  )
)
on Release pCont do
(
)

But it did not work...im not a scripter ! So does anyone know where Im going wrong. I jut inserted the 3 figures in the orientation array to see if anything would happen.....

I'm not sure i understood the question. The script indicates you want them all oriented the same way, right ? Then why not use the standard ops to set a fixed orientation ?

Apologies...I'll try and explain.
Say I have a bunch of sharks and they are all heading across the screen with their fins on top. For my animation I require the fins to be rotated randomly around the axis of the direction they are travelling.

The numbers I put in the script were just numbers to test if the script had any effect on the particles. I would have changed one of them to a randomly generated number..

Ah, got you. Well in this case you can still use the rotation operator. Set it to speed space, set the original orientation via x/y/z and use divergence to add a random offset. Or do you mean the orientation should "wobbel" while travelling ?

No it doesnt need to wobble..just initially be randomly oriented around one axis..

Thanks a lot for the help.
