Trying to tally keyframe values
I’ve been struggling to make this work. Maybe someone here has an idea.
I have two sliders. Slider A and Slider B.
Slider A has several keyframes of various values.
Every time it has a value of 5 I want to add 1 to the value of Slider B, but all I can seem to do is get it to “change” its value, not add to it. Once Slider A’s value changes, Slider B goes back to normal.
As you can see what I’m trying to do is tally the number of times a specific value is represented. I intend to do this for several other values too, but for the sake of this example, this is enough.The closest thing I’ve found to this is a counter that counts the number of times a ball is in a certain part of the screen. It’s not quite the same, but the concept is pretty similar.

It’s not too complicated if the expression can expect a slider A keyframe with the value of exactly 5 wherever it needs to tally:
SliderA = effect("Slider A")("Slider");
count = 0;
for (i = 1; i <= SliderA.numKeys; i++){
if (SliderA.key(i).time > time) break;
if (SliderA.key(i).value == 5) count++;
}
count
Otherwise, it gets more complex.

It works! I don’t understand everything the script is saying, but I know enough to change what it’s affecting and targeting. Thank you very much! This was a big help to me.
