Layer follow problem
Ok so I’ve got this company timeline with kind of a tool tips window that follows along as a pointer moves. The problem is that I need to have the tool tips window stay put until the pointer gets to where it’s going. I control the X position of the pointer with a slider.
Here’s the position code so far:
y = value [1];
val = thisComp.layer(“XSlider”).effect(“Slider Control”)(“Slider”);
follow = val%100;if (follow > 9 < 10) { ease (follow, 9, 10, 0, 10) } else if (follow > 19 < 20) { ease (follow, 19, 20, 10, 20) } // a bunch of other else statements go here for 29 to 30 and so on up to 40 x = value + (follow * 10); [x, y] The problem I'm having is that the else statements don't seem to be working. my tool tips layer hangs at 0 until I get to 9 then smoothly moves from 9 to 10, but when the slider control gets to 19 nothing happens. The marks on the timeline are 100 pixels apart so I multiply the follow distance by 10 I'm probably missing something simple. Maybe this requires a logical operator.

Play around with this:
y = value [1];
val = thisComp.layer(“XSlider”).effect(“Slider Control”)(“Slider”);period = Math.floor(val/10);
x = ease (val%10 +1, 9, 10, period*100, period*100 + 100);

Oops,
I that one had an error. Try this:
y = value [1];
val = thisComp.layer(“XSlider”).effect(“Slider Control”)(“Slider”);period = Math.floor(val/10);
x = ease (val%10, 9, 10, period*100, period*100 + 100);

Thanks, I’ll give that a try.

here’s what I came up with
val = thisComp.layer(“Control”).effect(“XPosition”)(“Slider”);
period = Math.floor(val/10);
offset = ease (val%10, 9, 10, period*10, period*10 + 100);x = linear (offset, 0, 100, 600, 0)
I’ve redesigned the project a bit and am using the offset filter instead of position because of some 3D and scale issues.
Everything works except that I can’t go above 100 on the slider.
Thanks again for your help…

Can you right click the slider number and reset the Max on the slider?

got it figured out. Used the remainder function (%) to loop the slider value at 100.
Now if I could just get the thing to work with negative numbers…. but that’s another project.
here’s the working code.
val = thisComp.layer(“PositionController”).effect(“xPosition”)(“Slider”)%100;
period = Math.floor(val/10);
offset = ease (val%10, 9, 10, period*10, period*10);x = linear (offset, 0, 100, 1, 6000)
y = value [0];[x, y]

It has an error…
…
x = linear (offset, 0, 100, 1, 6000)
y = value [0];[x, y]
The variable y should be value[1], like this
x = linear (offset, 0, 100, 1, 6000)
y = value [1];[x, y]

yup…. Just a type-0…
Nice catch though
