Inertial Bounce Scale – NOT starting from zero
Hi
I’ve been using this expression to add a bounce to scale:rate = 500;
rampDur = value[0]/rate;
freq = 3;
decay = 5;
w = freq*Math.PI*2;if (time < (inPoint+outPoint)/2){
if (time < (inPoint + rampDur)){
s = linear(time,inPoint,inPoint+rampDur,0,value[0]);
}else{
t = time – (inPoint+rampDur);
s = value[0] + rate*Math.sin(t*w)/Math.exp(t*decay)/w;
}
}else{
if (time > (outPoint – rampDur)){
s = linear(time,outPoint-rampDur,outPoint,value[0],0);
}else{
t = (outPoint – rampDur) – time;
s = value[0] + rate*Math.sin(t*w)/Math.exp(t*decay)/w;
}
}
[s,s]What I don’t like about it is that it kicks in at the first frame of the layer, and always starts from zero. Is there a way to scale up from, say, 100% to 150% AND add a bounce to it? Preferably this wouldn’t need to occur at the start of a layer.
Thank you
