slider expression
I would like to add an expression to a slider control that says:
starting at “time” subtract or add “amount” over “time” then hold for “time” then repeat.
does this make sense?

right now I’m just keyframing the slider to subtract 250 over ten frames then hold for two seconds then again subtract 250 over ten frames then hold for two seconds.
I can put eases on the keyframes, what about in an expression.Thanks (I’ll learn this stuff one day)
Thank You

Something like this:
moveTime = 10; // frames
holdTime = 2.0; // seconds
amount = -250;segDur = moveTime*thisComp.frameDuration + holdTime;
seg = Math.floor(time/segDur);
t = time%(segDur);
value + seg*amount + linear(t,0,moveTime*thisComp.frameDuration,0,amount)Dan

Wow that works like a charm, thank you very much, but the code is very complex to me any chance you can expound on the different parts of it.
1 question why is “moveTime = 10; // frames” in frames but “holdTime = 2.0; // seconds” is seconds how are frames distinguished from seconds?Thank You
