Actually I think I’ve figured it out. Not sure that this is the most elegant solution, but this is what I came up with…

if (transform.position[1] < 460) t = 0 else
t = (transform.position[1] - 460)/160
linear(t, 100, 0)

Hi, I actually miswrote what I meant. If y is less than 460, then I need opacity needs to be 100%, if it’s greater than 620, it needs to be 0%

Position needs to be listed as an array [x,y]. So if you want to parent the X position to rotate, enter the code:
temp = thisComp.layer(“layerName”).transform.rotation;
[temp, y]
where “y” is whatever the y position already was.

temp = thisComp.layer("layerName").transform.rotation;
[temp, y]

Thanks again!

Yep, that did it, thanks! Is there a similar code to parent to the y-axis?

I’m having this problem, too. It seems like when I rotate on the X and Y axis, it rotates globally, but when I rotate on the Z axis, it rotates locally. Again, this is regardless of what mode After Effects is set in. This is actually a huge problem because I need to control its orientation through an expression, so I need to be able to rotate this thing the way I want to by keyframing rotation. Have any solutions been found since this was originally posted?

That did it! Thank you
