Hey thanks Liran! Sorry the post took so long to clear on the forum that I actually figured it out myself ☺
I have a few sliders to animate the distance the elements travel out (Dist) and the amplitudes of all the wiggles (Amp)
I ended up just doing this:
Freq = random(2,8);
Tempamp = thisComp.layer("Dotts_wiggler_cntrls").effect("Amp")("Slider");
Amp = random(Tempamp/2, Tempamp*2);
W = wiggle(Freq, Amp)-value;
xSpread = wiggle(0, (thisComp.layer("Dotts_wiggler_cntrls").effect("Dist")("Slider"))*2);
ySpread = wiggle(0, thisComp.layer("Dotts_wiggler_cntrls").effect("Dist")("Slider"));
zSpread = wiggle(0, thisComp.layer("Dotts_wiggler_cntrls").effect("Dist")("Slider"));
[xSpread[0]+W[0], ySpread[1]+W[1], zSpread[2]+W[2]]
