Scale expression trouble
I am trying to get a layer to scale like a drum hit randomly through out my comp.
I am using this expression for the drum look:
veloc = 35;
amplitude =60;
decay = 10;
y = amplitude*Math.cos(veloc*time)/Math.exp(decay*time);
value + [0,y]I am just not sure where or how to add an expression to make this happen randomly over time.
Another thing I am have some trouble with is how can I setup a expression on the scale as well so the scale picks a random number between like 3-8% and sticks to, doesnt change.
Any help would be GREATLY appeciated.
Thanks in advance

Hi
[michaelvfx] “Another thing I am have some trouble with is how can I setup a expression on the scale as well so the scale picks a random number between like 3-8% and sticks to, doesnt change.”seed=Math.floor(time/1);
seedRandom(seed, true);
value+random(3,8)
// every second the scale value changes randomly between 3+8
