How to control the starting time in terms of expression?

[ILJC]

Hallo again!

I know there must be some ways to trigger the expression to start not immediately, but at any time I wish.

For e.g. I have here a code:

veloc = 35;

amplitude = 30;

decay = 1.0;

y = amplitude*Math.cos(veloc*time)/Math.exp(decay*time);

value + [0,y]

And I would like to delay the start in 2sek not just by pulling the layer to the right, but to do it in terms of a code.

Could anybody give me a hint?

would be very thankful

See this page for an example that should get you started.

The codes were really very helpful, thak you!

That was helpful, thank you!

I think this is more what you're looking for:

timeToStart = 2;
t = time - timeToStart;
if (t >= 0){
  veloc = 35;
  amplitude = 30;
  decay = 1.0;
  y = amplitude*Math.cos(veloc*t)/Math.exp(decay*t);
}else{
  y = 0;
}
  value + [0,y]
