Starting an Expression at a Specific Time
Hi All,
So I’m trying to get an expression to start at a specific time, but I’ve not been able to get it to work. Here is the one I’m trying to do:veloc = 7;
amplitude = 80;
decay = .7;amplitude*Math.sin(veloc*time)/Math.exp(decay*time)
It’s a pendulum motion that I’m applying to the X axis on a layer. Should I maybe be using a different expression for this that would allow me to stop and start it ? Thanks.

Something like this, probably:
timeToStart = 4; // start at 4 seconds
if (time < timeToStart){ deltaX = 0; }else{ t = time - timeToStart; veloc = 7; amplitude = 80; decay = .7; deltaX = amplitude*Math.sin(veloc*t)/Math.exp(decay*t); } value + [deltaX,0] Dan
