How to use the loopOut(cycle) expression but also increment property position per cycle?
Hi there,
Basically i’m trying to make bubbles in a glass of beer. I would like to cycle the position and opacity properties on the layer. But everytime the cycle repeats I would like the position of the bubble to move 10 units to the right.
How woudl I go about writing this as an expression. I understand the cycle expression.
many thanks

You could create your own version of loopOut with an offset, like this:
if (numKeys > 1){
t0 = key(1).time;
t1 = key(numKeys).time;
delta = t1-t0;
t = (time-inPoint)%delta;
offset = Math.floor((time-inPoint)/delta)*[10,0];
valueAtTime(t0+t) + offset
}else
value

Thanks for the reply.
Been trying to work out what your code is doing. I’m kinda noob to code.
Do you think you could explain what each line is doing, just so I can learn how it works.What does the % sign mean?

The % sign is the modulus operator.
