How could I go about making particles spin in a circle, as if they were in a whirlwind or vortex?

I want the particles to move in a spiral. I’m not sure exactly how to do this though.

To further specify: Think of leaves in a dust devil or debris in a tornado.

Use math.sin and math.cos, and multiply their returned values by time passed.

Are there any solutions that would achieve a more realistic movement pattern?

Just simple rotation scripts. I’m trying to achieve more realism than just basic rotations though.

ya, I assume so… and if the particles, are attached with the part, they move with it in a circle, if they are not , they do not look good , because they emit in place… unless you have an emit directions that relates to the spin… so ya you would want more then just a rotation … I was playing around with something until 4:00 am, starting to get some good effects… have some more ideas to try out… plus perhaps another OS particle system you can find with collision. might be fun… downside is, prob can get a cool effect with a small model… making it all work with a normal sized tornado is another thing

is your whirlwind model, a mesh, or something that forms or what are you using for the source area that would be spinning? … (besides the needed effects to add)

  1. also what have you already tried and what were the results?

The whirlwind itself is also just more vfx. Also, I have only tried rotating the attachment/model, I’m not much of a scripter.
