Wiggle + bounce effects on scale
Hello to everyone,
I’m quite new on after effects scripts and this could be an easy question for most of you but for me is something impossible to solve. I would like to use in a layer two different animations on Scale, on one side a wiggle that should be working all the time; on the other side, at second 9 the layer’ scale gets increase and I want to use a bounce effect on it. I tried these two functions independently and they work well, but when I write both together on the Scale scripts just works one of them…
How can I use more than one function on the same script, this is a limit that I always have when using scripts?
Thanks!!
Martin R.
/*Animation1*/
w = wiggle(5,3);
[w[0],w[0]]/*Animation2*/
n = 0;
if (numKeys > 0){
n = nearestKey(time).index;
if (key(n).time > time){
n--;
}
}
if (n == 0){
t = 0;
}else{
t = time - key(n).time;
}if (n > 0 && t < 1){
v = velocityAtTime(key(n).time - thisComp.frameDuration/10);
amp = .05;
freq = 4.0;
decay = 8.0;
value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);
}else{
value;

Martin,
expression can generate only one final property driving result. Instead, consider one of the followings:
a) Add ‘Transform’ effect to a layer and apply wiggle effect to its scale transformation (If its selected to Uniform scale, use only wiggle(5,3) without further array).
b) Add null, place it at the center of a layer, parent layer to null and apply wiggle.On the layer, add the second expression to scale. Its a workaround, but should solve it.

Thanks Thomas! Useful videos there, I think I’ll use them 😀
