start operation on layer time instead of comp time

[F***@adobeforums.com]

I cannot get this peice of code to start to work its magic att the beginning of the layer its applied to instead of the beginning of the comp the layer is in.

veloc = 10;
amplitude = 150;
decay = 2;

amplitude*Math.sin(veloc*time)/Math.exp(decay*time)

I have tried just writing layertime but Im very new to this whole expression thing and have yet to start to se logic in the strings. So thanx for anny help

Easy fix:

t = time - inPoint;
veloc = 10;
amplitude = 150;
decay = 2;

amplitude*Math.sin(veloc*t)/Math.exp(decay*t)

Cheers Dan!
Much appreciated

And if I want to control the start time within the layer (ex: +3 seconds) were do I add it?

Thanx

Like this:

delay = 3;
t = time - (inPoint+delay);
if (t < 0){ value }else{ veloc = 10; amplitude = 150; decay = 2; amplitude*Math.sin(veloc*t)/Math.exp(decay*t) }
