Wiggle with intervals expression ?
Hi guys,
Im trying to animate the ECG line (with Particular), and im using wiggle on Y possition while particle constantly moves on X from left to right. The problem is, that I want to have the wiggle to turn on after specific periods of time, and then shut off again, and so on. For instance, it takes for a particle line to get from one side to another 4 seconds, I want to have the wiggle affect on Y position (this Y position wiggle is on separate slider control) to start every 1 second for for the duration 0.5 seconds, and so on. These intervals and durations are arbitrary.
Is there an expression that lets me do that? Thank you in advance for your assistance.

Something like this maybe:
amp = 100;
freq = 4;
spacing = 1;
dur = .5;
attack = .1w = wiggle(freq,amp);
t = time%spacing;
if (t < attack)
linear(t,0,attack,0,w)
else
linear(t,attack,dur,w,0)Dan
