Remapping array to slider with easing
Hi all
I have what I thought was simple that really has me stumped!
I’ve an array of y positions that I’d like to simply remap to a slider so the array[0] is 0 on a slider, array[1] is 1 on a slider, array[2] is 2 on slider….. so I can animate between positions with simple values on a slider.
I think there’s some loop to do that I can’t figure out, any help would be much appreciate!

It might be like this (unless you need tweening, which would be a little more complicated):
s = effect(“Slider Control”)(“Slider”);
yPos = [100,200,300,400,500];
idx = Math.round(clamp(s,0,yPos.length-1));
y = yPos[idx];

Many thanks Dan.
Apologies – I inadvertently pressed the Report Post button!!!
That’s great, but yes – really want tweening. I’ll go the long way round for now as it sounds quite complicated. Many thanks for your time.

There are a number of ways to do it, but this should work:
s = effect(“Slider Control”)(“Slider”);
yPos = [100,200,300,400,500];
idx = clamp(s,0,yPos.length-1);
idx1 = Math.floor(idx);
idx2 = Math.ceil(idx);
y1 = yPos[idx1];
y2 = yPos[idx2];
y = ease(idx,idx1,idx2,y1,y2);

Ohhh, thanks, amazing!! Will try when I get back in the morning. It’ll save so much time on this project as I can pretty much automate everything 😀
