Elastic Snap Expression
Hi,
I’m trying to write an expression similar to an old motion math script I remember, wherein an object scales from 0 to 100, and oscillates on either side of the 100% value with a certain degree of decay, ultimately settling on 100%.
I’ve searched the archives but I can’t seem to retrofit the expressions I find to suit my purposes. Is this type of thing even possible?
Any help woould be greatly appreciated.
Thanks in advance,

Something like this should get you started:
freq = 4.0;
decay = 1.0;
v = -100*(Math.cos(freq*time*2*Math.PI)/Math.exp(decay*time) – 1);

Thanks Dan, I’ll give that one a shot!
