Up and down
I’m looking for an expression that would take my y-position and decrease it by my desired amount every 2 frames and then bring it back to the original y-position in the next 2 frames.
I’ve tried using sin functions but those go below the original y-position, whereas I want my object to stop at the original position and not go past it.
Thanks for the help!

This should work:
amt = -10;
f = timeToFrames(time);
n = Math.floor(f/2);
if (n%2){
y = linear(time,framesToTime(n*2),framesToTime(n*2+2),amt,0);
}else{
y = linear(time,framesToTime(n*2),framesToTime(n*2+2),0,amt);
}
value + [0,y]

Thank you Dan, that worked!

Just figured I’d add in case anyone is ever looking for this expression. Replaced the values with Slider controls so now it’s easier to adjust values rather than manually retyping them all in.
x = effect("Slider Control 2")("Slider");
amt = (effect("Slider Control")("Slider"));
f = timeToFrames(time);
n = Math.floor(f/x);
if (n%2){
y = linear(time,framesToTime(n*(effect("Slider Control 2")("Slider"))),framesToTime(n*(effect("Slider Control 2")("Slider"))+(effect("Slider Control 2")("Slider"))),amt,0);
}else{
y = linear(time,framesToTime(n*(effect("Slider Control 2")("Slider"))),framesToTime(n*(effect("Slider Control 2")("Slider"))+(effect("Slider Control 2")("Slider"))),0,amt);
}
value + [0,y]
