I'm a expressions newbie and I've googled around but I cant seem to find a solution to my particular problem:
I have a linear wipe with the transition completion value animating from 0 to 100. I would like the value to then ramdomly move between 100 & 50, but smoothly.
I've tried using wiggle but the results are jagged, the the value seems to just jump straight to another rather than traveling.
Any help would be much appreciated
What frequency and amplitute values do you use? wiggle() by it's nature should be smooth - it's simply a bunch of sinus curves overlapping and animating with progressive phase. Try small values like 0.3 for the frequency. The only otehr thing that could influence this would be if you somehow manually changed the random seed using seedRandom() somewhere. If you wnat things to be even smoother, you can always use the .smooth() method after the wiggle to apply box filtering.
ah you are correct, i had the frequency up too high!
