So, I’m working on a special effect using Shuriken particles that involves particles created at the shell of a sphere being sucked toward the center of the particle system. In the old particle system, I would use TangentVelocity.z = -1 to achieve this.
However, after experimentation and Google, I have not found a way to do this. Should I use legacy particles to achieve this effect, or is it possible with Shuriken?
If it’s not, could the capability be added? Seems a bit silly that a particle system would lack this sort of functionality.
(Given that we don’t have a particle system forum, this appears to be the best place for a particle system question. Please, correct me if I asked in the wrong place.)
If you are willing to script then its certainly possible you can control the movement of every particle.
Check out my game Vibre (made for iOS but it still works on Web), the entire view (minus the menus) is built as one particle systems.
Easy way is to set the Start Speed in the “Particle System” section to a negative value.
Dosen’t work, if start speed is less than 0, Unity just defaults it to 0.
EDIT: Nice username.
Also, 1500th post!
Works fine for me on 4.1.5f1. Post a screenshot of your settings.
Oh, and thanks 
Yeah…thanks. I must’ve been messing with some other setting that wouldn’t let it dip below 0… -1 appears to work just fine, in fact…
I was wrong! Thanks for setting me straight.
For future reference if anybody comes looking, these settings achieve that effect:
