Animate Between 2 Slider Values Help
Hello!
Hoping someone can help me out with this.
I have 2 static Slider values and I’m looking for a way to animate from 0 > Slider 1 > Slider 2 (diagram attached)
Not sure what the best way of doing this is when there are 3 values, as I can’t seem to get the Linear function to work for this. Wondering if there’s some combination of If Else with two different Linear functions to separate between A-B and B-C.
Many thanks in advance!

Since posting this, I have put together an expression that works for what I need it for!
I have a control slider that animates from 0 – 1 then 1 – 2. This slider has the following expression:
anim = value;
startval = thisComp.layer(“CONTROLS”).effect(“START”)(“Slider”);
endval = thisComp.layer(“CONTROLS”).effect(“END”)(“Slider”);
if (anim<1) {linear(anim,0,1,0,startval)}
else {linear(anim,1,2,startval,endval)}
Still interested in case there’s a more efficient way of doing this, so open to ideas 🙂

Hi Sammy!
I think something like this would work:
anim = value;
startval = thisComp.layer(“CONTROLS”).effect(“START”)(“Slider”);
endval = thisComp.layer(“CONTROLS”).effect(“END”)(“Slider”);
linear(anim, 0, 2, 0, endval)
Although If you still want to preserve control over the “midpoint” value (B), you can adjust the scaling and leverage a remapping approach:
anim = value;
startval = thisComp.layer(“CONTROLS”).effect(“START”)(“Slider”);
endval = thisComp.layer(“CONTROLS”).effect(“END”)(“Slider”);
// Midpoint value (Slider 1)
midval = (startval + endval) / 2;
// Remap anim from 0-2 range to startval-midval-endval
linear(anim, 0, 2, 0, endval);
