where would I start with this expression?
Hi all,
I’m not too sure where to start with this one. Any help would be appreciated. I want to make a series of squares/pads (8 or so) that light up then slowly fade out over time. The pad would only light up based of a selector of some sort – but once the pad is not selected it would fade over time (I was thinking an expression slider, but my initial attempts with that don’t seem to work), so basically like a controllable light pad or something of the sort. In my initial attempts have failed unfortunately.
Erin.

The expression is likely going to depend on what you use as a selector. What did you have in mind?

I was thinking of using a slider, but that may not be the best solution. I saw you’re using markers to animate tutorial, do you think that solution could work?

Here’s you you could do it with a checkbox control:
C = effect(“Checkbox Control”)(“Checkbox”);
fadeIn = .2;
fadeOut = 1.0;n = 0;
if (C.numKeys > 0){
n = C.nearestKey(time).index;
if (C.key(n).time > time){
n–;
}
}
if (n > 0){
t = time – C.key(n).time;
if (C.key(n).value == 1){
ease(t,0,fadeIn,0,100)
}else{
ease(t,0,fadeOut,100,0)
}
}else{
0
}Dan
