Wiggling certain dimensions via sliders
My idea is to have a bunch of falling layers cover the screen for a beat then to fall away. I can do the falling in and out position part, but I am having a one heck of time with isolating the wiggle property to only the x and y parameters of the layer orientation. I was saving the position param for the falling expression I wrote.
I have little programming experience, and I know enough about expression and javascript to be confused.
Basically, I am trying to get a bunch of 3D layers to wiggle in the x and y dimensions only. I want each one to have it’s own random seed and each wiggle parameter has it’s own slider on a null object.
I was able to get the following to work, however a new value is generated on every frame, I want a slower change in orientation, think leaves floating.
[random(thisComp.layer(“Null 1”).effect(“minwiggle”)(“Slider”), thisComp.layer(“Null 1”).effect(“maxwiggle”)(“Slider”)),random(thisComp.layer(“Null 1”).effect(“minwiggle”)(“Slider”), thisComp.layer(“Null 1”).effect(“maxwiggle”)(“Slider”)),orientation[2]]
I know the problem is because I am using the random method. But when I try this approach with wiggle, I get all kinds of errors. Not to mention the expression doesn’t look as elegant as I think it should.
orientation[wiggle(thisComp.layer(“Null 2”).effect(“Wiggle Freq”)(“Slider”), thisComp.layer(“Null 2”).effect(“Wiggle Amp”)(“Slider”), octaves = thisComp.layer(“Null 2”).effect(“Wiggle Octaves”)(“Slider”), amp_mult = thisComp.layer(“Null 2”).effect(“Wiggle Amp Mult”)(“Slider”), t = time*thisComp.layer(“Null 2”).effect(“Wiggle Time”)(“Slider”)), wiggle(thisComp.layer(“Null 2”).effect(“Wiggle Freq”)(“Slider”), thisComp.layer(“Null 2”).effect(“Wiggle Amp”)(“Slider”), octaves = thisComp.layer(“Null 2”).effect(“Wiggle Octaves”)(“Slider”), amp_mult = thisComp.layer(“Null 2”).effect(“Wiggle Amp Mult”)(“Slider”), t = time*thisComp.layer(“Null 2”).effect(“Wiggle Time”)(“Slider”)), orientation[2]]
Basically I used the pick whip to connect wiggle parameters with my null object sliders.
Help, please.
Thank you in advance.

Goodness, that is most atrocious. First off assign your sliders to variables like:
min_wiggle=thisComp.layer(“Null”).effect(“Min Wiggle”)(“Slider”);
Then use those variables inside your formulas. I also wouldn’t use the orientation property, use the normal rotations instead. To isoalte results of your wiggle, simply use the array syntax:
X=wiggle(amp,freq)[1];
Wiggle always works in all dimensions, so no need for any special precautions. If you want different values for X and Y, your wiggle must be put in a function. Search the main AE forum, I believe Filip Vanduren once provided some full code and it included even some stuff for looping.
