I would have used Pop from Array but Resize should work too. Is there something else in the tree that's creating strands at a default length every frame?

It doesn't actually control the strand length, it's just the sum of deltas in the StrandPosition array. If you want to make the strand shrink, you can remove the last item from the StrandPostion array instead. gray From: [email protected]<mailto:[email protected]> [mailto:[email protected]<mailto:[email protected]>] On Behalf Of adrian wyer Sent: Wednesday, March 05, 2014 11:29 AM To: [email protected]<mailto:[email protected]> Subject: shrinking strands quick question (work goes on even after yesterday) i have a particle system firing points that have strands trailing after them, they stick to a surface on collision i have a state machine which, for starters, won't let me use "IsStuck" as a trigger, i can work around this, but it's bloody annoying the problem is that once the particle enters state 1, IE is stuck on the floor, i want the strand trail to shrink over time i have tried starting a timer on enter state 1, then grabbing values from the timer and subtracting them from .strandlength, but it only shrinks on the first frame, even though this is plugged into execute on every frame i can post a scene i f someone fancies having a look, or if anyone knows how to plot rocket trajectories and have them fade on impact, i'm all ears! thanks Adrian Wyer Fluid Pictures 75-77 Margaret St. London W1W 8SY ++44(0) 207 580 0829<tel:%2B%2B44%280%29%20207%20580%200829> [email protected]<mailto:[email protected]><blocked::blocked::blocked::blocked::mailto:ad<mailto:ad> [email protected]<mailto:[email protected]>> www.fluid-pictures.com<http://www.fluid-pictures.com><blocked::blocked::blocked::blocked::http://www.fluid- pictures.com/<http://pictures.com/>> Fluid Pictures Limited is registered in England and Wales.
