Slider control issue with wiggle expression
Hi, everyone!
I’m using wiggle to animate something, but I want it to slow down the frequency as it approaches the end of the composition. I have used a Slider control, so the expression looks like this…
wiggle(thisComp.layer(“Null 2”).effect(“Slider Control”)(“Slider”),200)
It works fine when I’m keyframing the Slider from 0 to 0.5 at the beginning of the comp, but when I try to keyframe it at the end from 0.5 back down to 0, the object goes crazy. Instead of slowing down the wiggle rate (which is what I intend it to do), it starts shaking rapidly as if it suddenly goes from 0.5 to like 500. When I scrub through the frames, the slider control indeed goes from 0.5 slowly back down to 0, but it definitely does not look like that’s happening.
I tried creating a test comp with the wiggling position of a solid controlled by the slider control that has been keyframed from 0 to 1 and later from 1 back to 0. It still looks like the solid starts jerking around violently after it hits the second keyframe at value 1.
What am I doing wrong here?
Thanks for the help! =]

this dan ebberts code was used to create progressive wiggle which was used in a space simulation ae project.
it should be what you’re looking for.https://forums.creativecow.net/thread/227/15975#15991
