Particle flow rotation (object) problem

#1

Hello everyone.

I’m having a small problem with particle flow. I’ve setup a pflow with a position particles on a plane (vertices).
Shape of particles is a simple box i’ve made. Now what i’m trying to to is make the particles (boxes) rotate 180 degrees
when a certain deflector hits them and then stop after he’s out of range of them.

The problem i’m having is that the particles are rotating but i’m not getting the animation of
the rotation itself but just an instant turn of the particles.

Imagine yourself holding a card and flipping it around, the flip itself happens but the
animation of the flip doesn’t happen, just an instant flip =)

Is there any way of seeing the rotation animation happening without a script?

Have you tried Go To Rotation test? If I understand you correctly that should do the trick.

#3

lol…well you can do a dirty dirty hack and have 18 deflectors slightly spaced apart each rotating the particle ten degrees :stuck_out_tongue:

sounds like a script would be a lot better / flexible…

sorry wasn’t much help

Or use a Spin Operator instead of a Rotation Operator.

I did try a spin operator but they just kept on spinning after the deflector was past them.
I’m trying to let them stop after 180° og 360° =) But the spin operator atleast showed the
animation heh.

I tried the go to rotation but it didn’t work, maybe i was doing something wrong there though, don’t know.

Go To Rot should work just fine, you have to make sure you have a Rotation Op on the nxt event, this will define how much the particles will rotate.

#7

You can use a second Test (eg an Age Test or another Collision Test) to send the Partikels to another event, wehere you kill their rotation (either with a second Spin Operator with Speed 0, or the Stop (Gradually) Operator from Orbaz PFlow Freebies ).

Ok, thanks alot guys, i’ll try it as soon as i get home =)

Exactly :slight_smile: see the example. Rotation Operators give you a little more control over using a Spin op. The rotation duration is controlled by, in this case, the event duration, it is set to 30 frames so it will take 30 frames for the particle to flip from Rotation 01 to Rotation 02, upon reaching the end of Rotation 02 the particle is told to go to the next event via “Test True When: Transition Period Ends”
