Animate without Keyframes
usually i animate an object without keyframes using this expression :
ease(time,inPoint+0,inPoint+1,[0],[value]);
how to apply the effect of the expression below to the above
amp = .1;
freq = 1.0;
decay = 4.0;
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){
v = velocityAtTime(key(n).time – thisComp.frameDuration/10);
value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);
}else{value} -

The second expression requires keyframes.

Animation without keyframes
________________________________
1) Create Null with name = “Control”;
2) Create two sliders control: 1 – “Start Number”, 2 – “End Number”;
3) Create text layer and paste expression;
4) Create one marker on your text layer;
That’s all, Cheers ☺
_________________________________
startCount = thisComp.layer(“Control”).effect(“Start Number”)(“Slider”);
endCount = thisComp.layer(“Control”).effect(“End Number”)(“Slider”)*1000;
var num = Math.round(linear(time,inPoint,marker.key(1).time,startCount,endCount))
num = Comma(num);
[num]function Comma(number)
{
number = ” + Math.round(number);
if (number.length > 3)
{
var mod = number.length % 3;
var output = (mod > 0 ? (number.substring(0,mod)) : ”);
for (i=0 ; i < Math.floor(number.length / 3); i++)
{
if ((mod == 0) && (i == 0))
output += number.substring(mod+ 3 * i, mod + 3 * i + 3);
else
output+= ‘,’ + number.substring(mod + 3 * i, mod + 3 * i + 3);
}
return (output);
}
else return number;
}
