Randomly trigger animation?
I’m working on these complex transitions in which I’ve masked an HD video clip into 40 triangular facets with the anchor point adjusted on each so that when rotated 180° they reveal another piece of video behind them and on the other sides of the facets. It’s taking a lot of complex parenting and pre comps to make it work.
I’m keyframing the x rotation for each of the 40 layers (15 frames, easy-eased), then manually distributing the frames by dragging them around to create a sort of random cascade.
I’m wondering whether there’s a way to make those rotations trigger randomly between a set time frame. So, like, over the course of two seconds I want all 40 layers to rotate starting a different times within that timespan. Then by changing a random seed or something I could quickly get a different order of cascade.
Can this be done? If so, any thoughts as to how I’d approach that? I’m so-so on the expressions front.
Thank you.

It will probably be something like this:
tStart = 2; // earliest possible transiton start time
seedRandom(index,true);
myStart = tStart + random(2);
ease(time,myStart,myStart+framesToTime(15),0,180)which should start each transition somewhere between tStart (2 seconds in this example) and tStart+2.

Hi Dan:
Thanks for the quick reply. I’ll play around with this.
Take care.
