Not how did THEY create this… How did I do it??

Dave… yeah, exactly my point.

This, judging from the age of my boys was quite some time ago and probably was just something I quickly did as a test of process. I do have the final output as it now shows up at the end of my reel, but no – I don’t have the original project anymore.

I’ll keep digging.

Or you could tie expression controls to the wiggle parameters, and animate the controls.

Wow, that was a complicated expression =)

It shouldn’t be that difficult.

If you want it to be a wiggled value you could do something like this:


f = 2; //frequency of the wiggle
a = 10; //amplitude of the wiggle
k1 = key(2).time; //the time of the 2nd keyframe
k2 = key(3).time; //the time of the 3rd keyframe
mid = (k2 - k1) / 2; //midway between the 2nd and 3rd keyframe
offset = [0,0,0]; //how much the layer will be offset

delta = wiggle(f, a) - value; //the maximum offset (this value wiggles)

if(time < k1 + mid) offset = linear(time, k1, k1 + mid, offset, delta); //if we're not yet halfway between k1 and k2 then increase the offset from [0,0,0] at k1 to the maximum wiggled amount (delta) at the midpoint else offset = linear(time, k2, k2 - mid, delta, offset); //if we've passed the midpoint then decrease the offset from the maximum wiggled amount (delta) at the midpoint to [0,0,0] at k2 value + offset; //return the position value with the offset added

Note that the above code requires there be a 2nd and 3rd keyframe on the position property. This is a simple version of the effect, but it works.

Man, Victor!!!

Where’d you finally find that??? That was exactly the tutorial I remember.

Thanks SO much.

Darby — Giving that a try too.

Thanks SO much for everyone’s free time — or time for free is what I mean.

Please bless the givers.

FYI – for those of you keeping score:

t = time – key(2).time;
if (t<0){
value;
}else{
veloc = 30;
amplitude = 70;
decay = 4
x = amplitude*Math.cos(veloc*t)/Math.exp(decay*t);
value + [x,0];
}
