The problem with using and random value in a
type of expression is that when the random value changes, the rotational value for the rotor jumps to some random value. THat's not what we want.
Code: Select all
Time * (random value)
In QC the trick is the Integrator patch, which like the mathematical term takes the value history into account when determining the new rotational value. It's as simple as joining this set of five patches and entering your Min. Max values into the random patch and 0º and 360º into interpolation patch.
I know the expression in AE for Random and for Slider. I guess I can make keyframes for the Slider Value and do away with the need for a random expression to change the rotational speed at different points in time but how do I stop the rotor jumping around when I change the speed?
I could write an expression for a sin wave for the speed or a parabola but it seems like overkill and not really the desired level of "randomness" I'm looking for either.
